american college of sports medicine acsm guidelines
American College of Sports Medicine (ACSM) Guidelines
  • For Developing Cardiovascular Endurance

• Frequency – 3x/wk

• Intensity – 50-85% maximum heart rate

reserve or 50-85% maximum oxygen uptake reserve

• Duration – 20-60 minutes

• Mode – rhythmical and continuous

acsm guidelines continued
ACSM Guidelines Continued

• For Developing Muscular Strength

• 8-10 separate exercises using major

muscle groups

• 8-12 repetitions of each exercise to volitional fatigue

• 2-3 days/wk

• For Developing Muscular Endurance

• 15- 20 repetitions to volitional fatigue

acsm guidelines continued7
ACSM Guidelines Continued
  • For Developing Muscular Flexibility

• 5-15 minutes of moderate aerobic activity prior to stretching

• 2-3 days/wk after each aerobic workout

monitoring exercise intensity
Monitoring Exercise Intensity
  • Training Heart Rate Range

• % maximum heart rate (HR)

• % heart rate reserve (HRR) (Karvonen Formula)

• Training HR = (max HR - rest HR) X intensity percentage + RHR

• Example -- 20 y.o., rest HR = 70 bpm

• Training HR = (200 - 70) X 70% + 70 = 161 bpm

• 75% HHR = 85% max HR

warm up
Warm-Up
  • Group of exercises performed immediately before an activity
  • Provides adjustment from rest to exercise
  • 5-20 minutes depending on sport and environmental conditions
  • Active warm-up prior to vigorous stretching
cool down
Cool-Down
  • Purpose is to slowly decrease heart rate and lower body temperature
  • Active recovery promotes faster decrease in muscle and blood levels of lactic acid
  • Active recovery keeps the leg muscle “pump” going and prevents pooling of blood in the legs
  • Active recovery lessens chance of catecholamine produced cardiac irregularities in high risk persons
environmental considerations
Environmental Considerations
  • High air temperature and relative humidity increase risk for hyperthermia
  • Normal core temperature = 37 deg. C
  • Possible death at 45 deg. C
  • Factors affecting susceptibility to heat injury:

• Fitness level

• Hydration

• Clothing

• Metabolic Rate

• Wind

environmental considerations continued
Environmental Considerations Continued
  • Cold air temperature increases risk for hypothermia
  • Factors related to hypothermia

• Insulation—clothing and subcutaneous fat

• Air temperature

• Wind—accelerates heat loss (Windchill)

• Water vapor pressure—low in cold air which

increases evaporation and heat loss

environmental considerations continued14
Environmental Considerations Continued
  • Air pollution caused by ozone, sulfur dioxide and carbon monoxide

• Ozone—generated by combining UV light and internal combustion engine emissions. Decreases pulmonary function

• Sulfur Dioxide—fossil fuels (refineries). Causes bronchoconstriction in asthmatics

• Carbon Monoxide—fossil fuels, coal, oil, gasoline, wood and cigarette smoking. Decreases oxygen carry capacity of blood

medical considerations for exercise
Medical Considerations For Exercise
  • Physician Clearance
  • Medical History
  • Medication Profile
coronary artery disease cad
Coronary Artery Disease (CAD)
  • Narrowing of coronary arteries usually caused by arteriosclerosis (pathological condition resulting in thickening, hardening and loss of elasticity of arterial walls)
risk factors
Risk Factors
  • hypertension BP >140/90 mmHg
  • elevated blood lipids
      • total cholesterol > 200 mg/dl
      • LDL > 160 mg/dl (less than 2 risk factors)
      • > 130 mg/dl (2 or more risk factors)
      • > 100 mg/dl with CHD
      • HDL < 35 mg/dl
      • triglycerides > 400 mg/dl
risk factors continued
Risk Factors Continued
  • obesity
  • cigarette smoking
  • diabetes mellitus
  • psychological stressors
  • family hx early onset atherosclerosis
risk factors continued21
Risk Factors Continued
  • alcohol consumption
  • physical inactivity
  • age
  • gender—males 35-44 y.o. mortality rate 6x greater than females
  • elevated levels of homocysteine
coronary heart disease chd
Coronary Heart Disease (CHD)
  • Myocardial damage due to insufficient blood flow. The disease is caused by pathological changes in the coronary arteries sufficient to interfere with adequate blood flow.
chd continued
CHD Continued
  • exercise-induced complications—most occur in individuals with underlying heart disease or congenital abnormalities. A cardiac event during exercise is not common in individuals without heart disease. Exercise induced cardiac problems in those older than 35 tend to be due to CHD while those in individuals younger than 35 tend to be due to cardiovascular structural abnormalities.
chd continued24
CHD Continued
  • familial trait—there is a genetic predisposition to the development of CHD. The risk of a myocardial infarction (MI) is high when a MI or sudden death in a male first-degree relative occurs before age 55 and a female first-degree relative before age 65.
chd continued25
CHD Continued
  • Nicotine in tobacco smoke causes an increase in heart rate and blood pressure that increases the work of the heart (an increase in the rate-pressure product or double product). Nicotine may also increase platelet adhesiveness increasing blood viscosity. Carbon monoxide in tobacco smoke decreases the oxygen carrying capacity of red blood cells to the heart muscle.
chd continued26
CHD Continued
  • psychological stress—individuals with severe anxiety or frequent outbursts of anger exhibit higher levels of cardiac reactivity (characterized by increased heart rate, systolic blood pressure and peripheral resistance) as well as increased coronary artery spasms and sudden death
coronary disease continued
Coronary Disease Continued
  • Exercise Guidelines--guidelines are generalized due to multiple coronary diseases (e.g. CAD, CHD, myocardial infarction, coronary artery bypass graft, valvular disease, congestive heart failure, cardiac transplant, aneurysm, angina, cardiac arrhythmias )
coronary disease continued28
Coronary Disease Continued
  • Exercise Guidelines (continued)
  • General Considerations--
      • general low fitness levels
      • monitor for abnormal exercise response
      • awareness of other medical conditions
      • In-patient (Phase I) cardiac rehabilitation
      • Out-patient (Phases II-IV) cardiac rehabilitation
coronary disease continued29
Coronary Disease Continued
  • Aerobic/Endurance
      • 40-70% of vo2 peak
      • 3-7 d/wk
      • 20-40 min
  • Strength
      • higher repetitions, lower resistance
      • 2-3 d/wk
  • Flexibility
      • 2-3 d/wk
asthma exercise induced
Asthma/Exercise Induced
  • causative factors—asthma is characterized by increased airway reactivity to various stimuli including exercise. During an attack biochemical mediators are released due to mast cell degranulation causing airway smooth muscle constriction (bronchospasm).
asthma continued
Asthma Continued
  • Physical stimuli such as cooling and evaporation across airway epithelium during exercise or cold air exposure may directly stimulate the release of biochemical mediators. Individuals with exercise induced asthma may demonstrate normal airway function at rest but may develop bronchospasm during or after exercise.
asthma continued33
Asthma Continued
  • preventative measures—
      • identification and elimination of precipitating agents (pollens, dust mites, animal dander, drugs, foods, wine, exposure to fumes and chemicals)
      • education to improve compliance with medication
asthma continued34
Asthma Continued
  • Preventative measures (continued)
      • pharmacological agents—inhaled corticosteriod bronchodilators as preventative medicine (can be used on an ongoing basis) and inhaled cromolyn sodium (used up to 15 minutes before beginning exercise) to stabilize mast cells before exercise
      • optimizing inhaled or oral bronchodilator therapy
chronic obstructive pulmonary disease copd
Chronic Obstructive Pulmonary Disease (COPD)
  • chronic asthma
  • chronic bronchitis
  • pulmonary emphysema
  • chronic bronchiolitis
pulmonary dysfunction exercise guidelines
Pulmonary DysfunctionExercise Guidelines
  • Exercise induced asthma (EIA)
  • individuals are often asymptomatic (or minimally symptomatic) between exacerbations. This population of individuals should be able to engage in vigorous exercise training.
modifications to exercise program for eia
Modifications to Exercise Program for EIA

• warm-up and cool-down periods

• type of exercise--outdoor running exacerbates EIA, swimming reduces incidence

• length of exercise--long, intense continues exercise causes more EIA than short bursts

• intensity of exercise-high intensity (above 80-90% of maximal heart rate) causes more EIA

• nasal rather than mouth breathing

• wear a mask or scarf in cold weather

• monitor exercise environment for potential allergens and irritants

exercise guidelines copd
Exercise Guidelines COPD
  • COPD—these individuals are often elderly and have high co-existing impairment of other organ systems. If oxygen saturation drops below + 90% (pulse oximetry) or arterial blood oxygen drops below 55 torr (arterial blood gas) supplemental oxygen should be used via nasal cannula.
exercise guidelines copd continued
Exercise GuidelinesCOPD Continued
  • Aerobic/Endurance—
      • Monitor dyspnea
      • 1-2 sessions 3-7d/wk
      • 30 min (shorter intermittent sessions initially)
      • target intensity—heart rate (HR) attained at a work rate equal to 85% of the peak work rate during an initial incremental test (other methods for target HR during exercise may not be appropriate due to ventilatory limitation, increased resting HR and considerable day-to-day variations in resting HR)
exercise guidelines copd continued40
Exercise GuidelinesCOPD Continued
  • Strength
    • low resistance, high repetitions
    • 2-3d/wk
  • Flexibility
    • 3 sessions/wk
  • Neuromuscular (walking, balance and breathing exercises)
    • daily
diabetes mellitus dm
Diabetes Mellitus (DM)
  • Type 1 (Insulin Dependent, IDDM)
  • absolute deficiency of insulin due to a marked reduction in pancreatic insulin-secreting beta cells. Insulin must be supplied by insulin injection or insulin pump. Cause is thought to involve an autoimmune response leading to the destruction of beta cells.
type 1 dm continued
Type 1 DM Continued
  • Are prone to develop ketoacidosis with marked hyperglycemia. Can occur at any age but usually before the age of 30. Represents 10% to 15% of individuals with DM.
dm continued
DM Continued
  • Type 2 (Non-Insulin Dependent, NIIDM)
  • relative insulin deficiency. May have elevated, reduced or normal insulin levels but have hyperglycemic. Usually a combination of peripheral insulin resistance and defective insulin secretion.
type 2 dm continued
Type 2 DM Continued
  • Resulting hyperglycemia causes beta cells to secrete more insulin that is usually ineffective in lowering blood glucose and further contributes to peripheral insulin resistance. Usually do not develop ketoacidosis. Usually occurs after the age of 40 but is becoming more common in younger individuals. Represents 85% to 90% of individuals with DM.
diagnostic criteria for diabetes
Diagnostic Criteria for Diabetes

• Symptoms of diabetes plus casual plasma glucose concentration of >200 mg/dL (11.1mmol/L) (casual is defined as any time of day without regard to time since the last meal); the classic symptoms of diabetes include polyuria, polydipsia, and unexplained weight loss; or

• Fasting plasma glucose of >126 mg/dL (7.0 mmol/L) (fasting is defined as no caloric intake for at least 8 hours); or

• Two- hour plasma glucose of >200 mg/dL during an oral glucose tolerance test; the test should be performed as described by World Health Organization, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water

insulin regulation
Insulin Regulation
  • blood levels of glucose
  • blood levels of amino acids potentiate the glucose stimulus for insulin secretion
  • gastrointestinal hormones—gastrin, secretin, cholecystokinin
  • other hormones—glucagon, growth hormone, cortisol, progesterone and estrogen
metabolic complications
Metabolic Complications
  • ketoacidosis
  • dehydration
  • retinopathy
  • hypertension
  • neuropathy
  • nephropathy
  • atherosclerosis
  • poor wound healing
medications dm
Medications (DM)
  • Type 1--most individuals use subcutaneous insulin injections consisting of a mixed insulin, split dose regimen. This includes a mixture of short-acting insulin and longer-acting (sustained release) insulin in morning and afternoon doses.
medications dm continued
Medications (DM) Continued
  • Type 2--oral hypoglycemic agents that help restore peripheral insulin receptor sensitivity and stimulate pancreatic insulin release
  • Type 1/Type 2--also antihypertensive, lipid-lowering and pain medications
exercise benefits dm
Exercise Benefits (DM)
  • Type 1—exercise is not considered a component of treatment in type 1 diabetes to lower blood glucose but individuals should exercise to gain other benefits normally associated with regular exercise
exercise benefits dm continued
Exercise Benefits (DM) Continued
  • Type 2—
  • improved daily blood glucose control
  • improved peripheral insulin sensitivity and insulin receptor affinity
  • other benefits normally associated with regular exercise
precautions for avoiding hypoglycemic events
Precautions for Avoiding Hypoglycemic Events
  • Measure blood glucose before, during and after exercise
  • Avoid exercise during periods of peak insulin activity
  • Unplanned exercise should be preceded by extra carbohydrate, e.g., 20 to 30 g/30 min of exercise; insulin may have to be decreased after exercise
  • If exercise is planned, insulin dosages must be decreased before and after exercise, according to the exercise intensity and duration as well as the personal experience of the patient; insulin dosage reductions may amount to 50 to 90% of daily insulin requirements
precautions for avoiding hypoglycemic events continued
Precautions for Avoiding Hypoglycemic Events Continued
  • During exercise, easily absorbable carbohydrates may have to be consumed
  • After exercise, an extra carbohydrate- rich snack may be necessary
  • Be knowledgeable of the signs and symptoms of hypoglycemia
  • Exercise with a partner
obesity57
Obesity
  • Criteria
  • Body Mass Index (BMI)
    • moderately overweight/obese--27.1-30.0 kg/m2
    • markedly overweight/obese--30.1-40.0 kg/m2
    • morbidly obese--> 40.0 kg/m2
obesity continued
Obesity Continued
  • Criteria (continued)
  • Percentage body fat
    • > 25% males
    • > 32% females
obesity continued59
Obesity Continued
  • Metabolic complications—Primary metabolic complication is the development of DM. In obesity the beta cells become less responsive to stimulation by increased blood glucose levels. In turn, the blood insulin levels do not increase when needed.
obesity continued60
Obesity Continued
  • Metabolic complications (continued)--In addition, obesity decreases the number of insulin receptors in insulin target cells. Other complications of obesity are hypertension, elevated serum cholesterol levels and decreased cardiorespiratory function.
criteria for weight loss program
Criteria for Weight Loss Program
  • Provides intake of not lower than 1200 kcal/day for normal adults and allows for a proper distribution of foods to meet the nutritional requirements. (Note: this requirement may not be appropriate for children, older individuals, and athletes)
  • Includes foods acceptable to the dieter in terms of sociocultural background, usual habits, taste, costs, and ease in acquisition and preparation; however, these foods should be low in total fat, saturated fat, cholesterol, and sodium
  • Provides a negative caloric balance (not to exceed 500 to 1000 kcal/day), resulting in gradual weight loss without metabolic derangements, such as ketosis
  • Results in a maximal weight loss of 1 kg/week
criteria for weight loss programs continued
Criteria for Weight Loss Programs Continued
  • Includes the use of behavior modification techniques to identify and eliminate diet habits that contribute to malnutrition
  • Includes an exercise program that promotes a daily caloric expenditure of more than 300 kcal. For many participants, this may be best accomplished with moderate-intensity, long- duration exercise, such as walking
  • Provides that new eating and physical activity habits can be continued for life to maintain the achieved lower body weight

      • atherosclerosis
      • impaired cognitive function
      • thickening and stiffening of medium and small blood vessels
      • retinopathy
      • nephropathy
htn continued68
HTN Continued
  • Medications—initiation of drug therapy should consider:
  • severity of HTN
  • presence or absence of target-organ disease
  • presence or absence of other medical conditions and CHD risk factors
htn continued69
HTN Continued
  • Pharmacological agents—
      • alpha blockers—block adrenergic vascular smooth muscle receptors which promotes a decrease in vascular resistance
      • beta blockers—block adrenergic receptors in the heart decreasing heart rate and myocardial contraction force
      • alpha-beta blockers
htn continued70
HTN Continued
  • Pharmacological agents (continued)
      • calcium channel blockers—block entry of calcium into vascular smooth muscle inhibiting contraction leading to vasodilation and decreased vascular resistance
      • angiotensin-converting enzyme inhibitors—inhibit transformation of angiotensin I to angiotensin II (angiotensin II is a vasoconstrictor)
      • diuretics—decrease fluid volume within the vascular system
lifestyle modifications for hypertension
Lifestyle Modifications for Hypertension
  • Lose weight if overweight
  • Limit alcohol intake to no more than 1 oz (30 mL) of ethanol (e.g., 24 oz [720 mL] of beer, 10 oz [300 mL] of wine, or 2 oz [60 mL] of 100 proof whiskey) per day or .5 oz (15 mL) of ethanol per day for women and lighter-weight people
  • Increase aerobic physical activity (accumulate 30 to 45 minutes most days of the week)
  • Reduce sodium intake to no more than 100 mmol/d (2.4 g of sodium or <6 g of sodium chloride)
  • Maintain adequate intake of dietary potassium (approximately 90 mmol/d or 3.5 g/d)
lifestyle modifications for hypertension continued
Lifestyle Modifications for Hypertension Continued
  • Maintain adequate intake of dietary calcium and magnesium for general health
  • Stop smoking
  • Reduce intake of dietary saturated fat and cholesterol for overall cardiovascular health
recommendations for exercise training and testing for hypertensives continued
Recommendations for Exercise Training and Testing for Hypertensives Continued
  • Mass exercise testing is not advocated to determine those individuals at high risk for developing hypertension in the future as a result of an exaggerated exercise BP response. However, if exercise test results are available and an individual has a hypertensive response to exercise, this information does provide some indication of risk stratification for that patient and the necessity for appropriate lifestyle counseling to ameliorate this increase. In certain instances, medication changes may be appropriate
recommendations for hypertensives continued
Recommendations for Hypertensives Continued
  • Endurance exercise training by individuals who are at high risk for developing hypertension will reduce the rise in BP that occurs with age, thus justifying its use as a nonpharmacologic strategy to reduce the incidence of hypertension in susceptible individuals
  • Endurance exercise training will elicit an average reduction of 10 mm Hg for both systolic and diastolic BP in individuals with stage 1 or stage 2 essential hypertension(BP in the range of 140 to 179/90 to 109 mm Hg) and even greater reductions in BP in patients with secondary hypertension due to renal dysfunction
recommendations for hypertensives continued75
Recommendations for Hypertensives Continued
  • The recommended mode, frequency, duration, and intensity of exercise are generally the same as those for low risk individuals. Exercise training at somewhat lower intensities (e.g., 40 to 70% VO2 max) appears to lower BP as much as, if not more than, exercise at higher intensities, which may be especially important in specific hypertensive populations, such as elderly
recommendations for hypertensives continued76
Recommendations for Hypertensives Continued
  • Based on the high number of exercise-related health benefits and low risk for morbidity and/or mortality, it seems reasonable to recommend exercise as part of the initial treatment strategy for individuals with stage 1or stage2 essential hypertension.
  • Individuals with more marked elevations in BP should add endurance exercise training to their treatment regimen only after initiating pharmacological therapy; exercise may reduce their BP further, allow them to decrease their antihypertensive medications, and attenuate their risk for premature mortality
recommendations for hypertensives continued77
Recommendations for Hypertensives Continued
  • Resistance training is not recommended as the primary form of exercise training for hypertensive individuals. With the exception of circuit weight training, resistance training has not consistently been shown to lower BP. Thus, resistance training is recommended as a component of a well rounded fitness program, but not when done independently
osteoporosis
Osteoporosis
  • systemic skeletal disease characterized by low bone mineral density (BMD) leading to bone fragility and increased risk of fracture
  • Osteoporosis exercise related prevention goals—
      • to increase bone mass during and just after periods of growth
      • to maintain bone mass or decrease the rate of loss in adulthood
      • to decrease incidence of falls in older adults
osteoporosis continued
Osteoporosis Continued
  • Exercise Guidelines—
  • Aerobic--
      • walking, cycling, swimming (activities with a weight-bearing component are associated with a higher BMD than those without a weight-bearing component)
      • 40-70% of peak HR
      • 3-5d/wk
      • 20-30 min/session

      • long-term effect on bone mass conservation will require at least 9-12 mo of exercise training
      • avoid flexion of spine and stooping with forward flexion (can increase vertebral fractures)
      • cardiac complications (due to older age of most individuals with osteoporosis)
      • start with low workouts and progress slowly due to low muscular strength in many individuals with osteoporosis
      • amenorrheic and postmenopausal women (hypoestrogenism)
arthritis

lbp continued93
LBP Continued
  • Exercise Guidelines (continued)
      • low impact aerobic exercise (e.g. walking) can provide very low levels of supporting tissue load while activating supporting back musculature
      • low back muscle endurance and strengthening exercises can reduce incidence of low back injury (endurance > strength)
lbp continued94
LBP Continued
  • Exercise Guidelines (continued)
      • flexibility exercise (unloaded flexion-extension) can be initiated in individuals with LBP after the spine has been stabilized and after endurance and strength conditioning has occurred
      • abdominal exercise that produces low back spine compression
      • exercises can be performed daily
guidelines for strength training for children
Guidelines for Strength Training for Children
  • All strength- training activities should be supervised and monitored closely by appropriately trained personnel
  • No matter how big, strong, or mature the individual appears, remember that he or she is physiologically immature
  • The primary focus, at least initially, should be directed at learning proper techniques for all exercise movements and developing an interest in resistance training
guidelines for strength training children continued
Guidelines for Strength Training Children Continued
  • Proper techniques should be demonstrated first, followed by gradual application of resistance or weight
  • Proper breathing techniques (ie.,no breath-holding) should be taught
  • Stress that exercises should be performed in a manner in which the speed is controlled, avoiding ballistic (fast and jerky) movements
guidelines for strength training children continued100
Guidelines for Strength Training Children Continued
  • Avoid the practice of power lifting and body building
  • Perform full-range, multi-joint exercises (as opposed to single-joint exercises)
  • Be sure participant can understand and follow directions
strength training exercise prescription for children
Strength Training Exercise Prescription for Children
  • Intensity
    • Avoid repetitive use of maximal amounts of weight in strength training programs until reaching Tanner stage 5 (adolescence) level of development maturity
    • Weight loads should be used that permit 8 or more repetitions to be completed per set, since heavy weights can be potentially dangerous and damaging to the developing skeletal and joint structures
strength training exercise prescription for children continued
Strength Training Exercise Prescription for Children Continued
  • Intensity Continued
    • It is not recommended that resistance exercise be performed to the point of severe muscular fatigue
    • As a training effect occurs, achieve an overload initially by increasing the number of repetitions, and then by increasing the absolute resistance
strength training exercise prescription for children103
Strength Training Exercise Prescription for Children
  • Duration
    • Perform 1 to 2 sets of 8 to 10 different exercises(with 8 to 12 repetitions per set), ensuring that all of the major muscle groups are included (in early stages of training, 1 set should be performed until proper technique is demonstrated)
    • Rest at least 1 to 2 minutes between exercises, and intersperse rest days between training days
strength training exercise prescription for children continued104
Strength Training Exercise Prescription for Children Continued
  • Frequency
    • Limit strength training sessions to twice per week and encourage children and adolescents to participate in other forms of physical activity
exercise testing changes with aging
Exercise Testing, Changes With Aging
  • Resting Heart Rate - no change
  • Maximal Heart Rate- decrease
  • Maximal Cardiac Output- decrease
  • Resting and Exercise BP- increase
  • Maximal oxygen uptake- decrease
  • Residual volume- increase
  • Vital Capacity- decrease
  • Reaction time- increase
exercise testing changes with aging continued
Exercise Testing, Changes With Aging Continued
  • Muscular strength- decrease
  • Bone mass- decrease
  • Flexibility- decrease
  • Fat-free body mass- decrease
  • Percent body fat- increase
  • Glucose tolerance- decrease
  • Recovery time- increase
considerations for testing the elderly
Considerations for Testing the Elderly
  • For those with expected low work capacities, the initial workload should be low (2 to 3 METS) and workload increments should be small (.5 to 1.0 METS), e.g., Naughton protocol
  • A cycle ergometer may be preferable to a treadmill for those with poor balance, poor neuromuscular coordination, impaired vision, senile gait patterns, weight-bearing limitations, and foot problems
considerations for exercise testing the elderly continued
Considerations for Exercise Testing the Elderly Continued
  • Added treadmill handrail support may be required due to reduced balance, decreased muscular strength, poor neuromuscular coordination, or fear. Handrail support or gait abnormalities, however, can reduce the accuracy of estimating peak MET capacity based on exercise duration or peak workload achieved
  • Treadmill speed may need to be adapted according to walking ability
  • For those who have difficulty adjusting to the exercise equipment, the initial stage may need to be extended, the test restarted, or the test repeated
considerations for exercise testing the elderly continued113
Considerations for Exercise Testing the Elderly Continued
  • Exercise- induced arrhythmias are more frequent in the elderly than in other age groups
  • Prescribed medications are common and may influence exercise electrocardiographic and hemodynamic responses
mode of exercise for the elderly
Mode of Exercise for the Elderly
  • The exercise modality should be one that does not impose excessive orthopedic stress
  • Walking is an excellent mode of exercise for many elderly
  • Aquatic exercise and stationary cycle exercise may be especially advantageous for those with reduced ability to tolerate weight -bearing activity
mode of exercise for the elderly continued
Mode of Exercise for the Elderly Continued
  • The activity should be accessible, convenient, and enjoyable to the participant- all factors directly related to exercise adherence
  • A group setting may provide important social reinforcement to adherence
intensity for exercise prescriptions for the elderly continued
-Intensity for Exercise Prescriptions for the Elderly Continued
  • To minimize medical problems and promote long-term compliance, exercise intensity for inactive elderly people should start low and individually progress according to tolerance and preference
  • Many older persons suffer from a variety of medical conditions; thus, a conservative approach to increasing exercise intensity is warranted initially
  • Exercise need not be vigorous and continuous to be beneficial; a daily accumulation of 30 minutes of moderate-intensity exercise provides health benefits
intensity for exercise prescriptions for elderly continued
Intensity for Exercise Prescriptions for Elderly Continued
  • Longer- duration or higher-aerobic intensity offers additional health benefits, although it can lead to greater risk of cardiovascular and musculoskeletal problems and lower compliance to a long term exercise plan
  • The intensity guidelines and precautions established for younger people for aerobic exercise training generally apply to the elderly
intensity for exercise prescriptions for the elderly continued118
Intensity for Exercise Prescriptions for the Elderly Continued
  • A measured peak heart rate is preferable to an age predicted peak heart rate when prescribing aerobic exercise because of the variability in peak heart rate in persons over 65 years of age and their greater risk of underlying coronary artery disease
  • Use of percentage of peak heart rate to calculate a target heart rate range in the elderly may provide a more accurate estimate of percentage of peak VO2 than the heart rate reserve method
  • Elderly persons are more likely than young persons to be taking medications that can influence peak heart rate
duration for exercise prescriptions for the elderly continued
Duration for Exercise Prescriptions for the Elderly Continued
  • Exercise duration need not be continuous to produce benefits; thus those who have difficulty sustaining exercise for 30 minutes or who prefer shorter bouts of exercise can be advised to exercise for 10 minute periods at different times throughout the day
  • To avoid injury and ensure safety, older individuals should initially increase exercise duration rather than intensity
frequency for exercise prescriptions for the elderly
Frequency for Exercise Prescriptions for the Elderly
  • Exercise performed at moderate intensity should be undertaken most days of the week
  • If exercise is undertaken at a vigorous level, it should be performed at least 3 times per week, with exercise and no exercise days alternated
resistance training guidelines for the elderly
Resistance Training Guidelines for the Elderly
  • Intensity
    • Perform at least 1 set of 8 to 10 exercises that use all the major muscle groups (e.g., gluteals, quadriceps, hamstrings, pectorals,latissimus dorsi, deltoids, and abdominals)
    • Each set should involve 10 to 15 repetitions that elicit a perceived exertion rating of 12 to 13 (somewhat hard)
resistance training guidelines for the elderly continued
Resistance Training Guidelines for the Elderly Continued
  • As a training effect occurs, achieve an overload initially by increasing the number of repetitions, and then by increasing the resistance
  • When returning from a lay-off, start with resistances of 50% or less of previous training intensity, then gradually increase the resistance
resistance training guidelines for the elderly continued123
Resistance Training Guidelines for the Elderly Continued
  • Frequency
    • Resistance training should be performed at least twice a week, with at least 48 hours of rest between sessions
  • Duration
    • Sessions lasting longer than 60 minutes may have a detrimental effect on exercise adherence.
    • Adherence to guidelines should permit individuals to complete total body resistance training sessions within 20 to 30 minutes
practical guidelines for resistance training for the elderly
Practical Guidelines for Resistance Training for the Elderly
  • The major goal of the resistance training program is to develop sufficient muscular fitness to enhance an individual’s ability to live a physically independent lifestyle
  • The first several resistance training sessions should be closely supervised and monitored by trained personnel who are sensitive to the special needs and capabilities of the elderly
  • Begin (the first 8 weeks) with minimal resistance to allow for adaptations of the connective tissue elements
practical guidelines for resistance training continued
Practical Guidelines for Resistance Training Continued
  • Teach proper training techniques for all of the exercises to be used in the program
  • Instruct older participants to maintain their normal breathing pattern while exercising
  • Stress that all exercises should be performed in a manner in which the speed is controlled (no ballistic movements should be allowed)
  • Perform the exercises in a range of motion that is within a “pain- free arc”
practical guidelines for resistance training continued126
Practical Guidelines for Resistance Training Continued
  • Perform multi-joint exercises (as opposed to single-joint exercises)
  • Given a choice, use machines to resistance train, as opposed to free weights (machines require less skill to use, protect the back by stabilizing the user’s body position, and allow the user to start with lower resistances, to increase by smaller increments, and to more easily control the exercise range of motion)
practical guidelines for resistance training continued127
Practical Guidelines for Resistance Training Continued
  • Never permit arthritic participants to participate in strength training exercises during active periods of pain or inflammation
  • Engage in a year- round resistance training program
  • Routine activities, such as domestic work, gardening, and walking, may help to maintain muscular strength
flexibility exercise prescription for the elderly continued
Flexibility Exercise Prescription for the Elderly Continued
  • Intensity
    • Exercises should incorporate slow movement, e.g., static stretches that are sustained for 10 to 30 seconds
    • At least four repetitions per muscle group should be performed
    • The degree of stretch achieved should not cause pain, but rather mild discomfort
flexibility exercise prescription continued
Flexibility Exercise Prescription Continued
  • Frequency
    • Stretching exercises should be performed a minimum of 2 to 3 d/wk and should be included as an integral part of the warm-up and cool-down exercises
  • Duration
    • The stretching phase of an exercise session should last long enough to exercise the major muscle/tendon groups
    • an entire exercise session devoted to flexibility may be appropriate for deconditioned older adults who are beginning an exercise program
stretching guidelines for older adults
Stretching Guidelines for Older Adults
  • Always precede stretching exercises with some type of warm-up activity to increase circulation and internal body temperature
  • Stretch smoothly and never bounce
  • Do not stretch a joint beyond its pain-free range of motion
  • Gradually ease into a stretch, and hold it only as long as it feels comfortable (10 to 30 seconds)
