Presentation Transcript
Chapter 5 Fitness programs
Barriers to physical activity • Lack of discipline • Lack of time • Feeling uncomfortable (physically and socially) • Lack of motivation • Boredom • Tiredness.
Fundamental principles of program design • Specificity • Overload • Progression • Detraining • Individuality
Components of fitness sessions • Resistance training • Cardiovascular training • Flexibility training.
Warm-up • Prepares the body and mind for what is to follow • Usually around 10−15 minutes of a one hour session, but varies • Gradual increase in heart rate for cardiovascular training.
Stimulus or conditioning phase • Goal focused • Includes muscle strength, endurance, cardiorespiratory and flexibility components • Continuous and/or intermittent activities.
Cool-down • Gradual return of body as close to resting state as possible • Length of time varies depending on intensity and duration of workout • Can help to prevent/minimise risk of dizziness.
Cardiorespiratory training • Improves VO2 max • Reduces maximal and resting heart rates • Increases stroke volume • Reduces body fat • Increases HDL levels • Improves glucose metabolism • Improves transport and use of oxygen.
Cardiorespiratory training • Beginners and unfit may start with as little as 10 minutes of training • Progress gradually to 20−60 minutes of training per session • Detraining can occur within 14 days of ceasing training.
Heart rate measurements • Can help with intensity measurements • Not suitable for those on medications affecting heart rate and pregnant women • Carotid pulse • Radial pulse.
Prediction of maximal heart rate • PMHR = 208− (0.7 x age) • Measured in beats per minute (BPM).
Starting intensities • Beginner with low fitness <60% max heart rate • Beginner with average fitness 60−70% max heart rate • Aerobically trained 70−85% max heart rate.
Heart rate reserve or Karvonen formula • Target heart rate at 60% = ([MHR – HRR] x 0.60) + RHR
Rate of perceived exertion • Subjective measure of intensity • Useful when heart rate measurements are inappropriate, e.g. pregnancy • Modified scale 0−10 • 0 = nothing at all • 10 = very, very strong—maximal.
Resistance training • Muscular strength • Muscular endurance—static and dynamic • Not possible to completely train one aspect without the other benefitting somewhat.
Benefits of resistance training • Increased muscle size • Increased ligament and tendon strength • Increased muscle strength and endurance • May help to improve posture • Injury rehabilitation • Delay the age-associated muscle atrophy
Benefits of resistance training (continued) • Alter body composition • Reduced the risk of osteoporosis • Improved self image.
4 Rs of resistance overload • Repetitions • Resistance • Rate • Rest
Types of flexibility training • Static • Dynamic • Ballistic • Proprioceptive neuromuscular facilitation (PNF).
