Short Term (Acute) Physiological Responses to Exercise

Effects that take place

while we are exercising…

short term physiological responses to exercise immediate or acute effects of exercise on the body
Short Term Physiological Responses to Exercise Immediate or acute effects of exercise on the body.

TASK:

  • Measure your ‘resting’ heart rate (15 seconds then x4)
  • 1 minute of strenuous exercise (star jumps, squat jumps, press ups, lunge jumps).
  • Measure heart rate (15 seconds then x4)
  • Listen to my instructions for timing
slide10
Thinking about the 1 minute of exercise you just did- What effects did you feel taking place within your body?

BRAINSTORM

short term physiological responses to exercise immediate or acute effects of exercise on the body1
Short Term Physiological Responses to Exercise Immediate or acute effects of exercise on the body.

Simplified answers:

  • Increased temperature
  • Increased heart rate
  • Increased respiration

ACHIEVED !!

muscular system increased temperature
Muscular System- Increased Temperature
  • Muscles receive more

blood and oxygen

          • Working harder
  • Muscles increase

in temperature

          • Bi-product of energy production
          • Blood moves to surface of the skin (heat regulation)
          • Sweating (heat regulation)
cardiovascular cardiac output increases the heart beats faster and stronger
Cardiovascular- Cardiac Output Increases“The heart beats faster and stronger”
  • The heart rate increases to ensure that

more oxygen is delivered to the working

muscles.

  • This also allows Co2 to be

removed from the body.

  • Stroke volume also

increases so the amount of

blood processed each beat

increases.

  • (Cardiac output (Q) = SV x HR)
respiratory system increased ventilation breathing quickens and deepens
Respiratory System- Increased Ventilation“Breathing quickens and deepens”
  • Increase in the number of breaths per minute

(respiratory rate)

  • Increase in the amount of air taken in each breath.

(tidal volume)

long term chronic physiological responses to exercise

Long Term (Chronic) Physiological Responses to Exercise

Effects that take place following exercise weeks, months, years later…

  • Muscular system
  • Cardiovascular/ Circulatory system
  • Respiratory system

Think about the effects of training on the body. Try to link your answer to the three energy systems.

BRAINSTORM

long term physiological responses to exercise effect of training on the body
Long Term Physiological Responses to Exercise Effect of training on the body.

Simplified answers:

  • Muscles increase in size and strength.
  • Size of the heart increases.
  • The heart pumps more blood per beat (stroke volume).
  • The cardiovascular system becomes more efficient.
  • The recovery rate becomes quicker.
  • Resting heart rate becomes lower.

ACHIEVED !!

muscular system
Muscular System
  • Muscles increase in size and strength
        • Hypertrophy
        • Receiving more O2
        • Working harder
  • Muscles become more flexible
        • Subject to training
  • Muscles receive more O2
        • From increases in the cardio

respiratory system

cardiovascular system
Cardiovascular System
  • Increased heart size
      • Because the heart is a muscle too! The heart is

pumping much more blood around the body to

produce O2 and remove CO2.

  • Exercising heart rate becomes lower
      • Because the heart is larger (more blood pumped through per beat)
  • Increased stroke volume
      • Because the heart is larger (more blood pumped through per beat)
  • Decreased resting heart rate
      • Heart is bigger, therefore it doesn’t need to pump as often
respiratory system
Respiratory System
  • The lungs can breathe in and out a greater volume of air, and with it oxygen.
    • Increased efficiency for exchange in the lungs and muscles.
    • This means more O2 being delivered to muscles and more Co2 being removed from the muscles.
the interconnection between the 3 energy systems
The Interconnection between the 3 Energy Systems
  • Muscular system
  • Cardiovascular/ Circulatory system
  • Respiratory system

None of these effects are possible unless all three energy systems work together to increase O2 and remove Co2.

sticky notes
Sticky Notes
  • One thing you do not understand fully from the last two lessons (short term & long term effects of exercise).
  • The aspect/ aspects that are the most difficult to understand from the whole content anatomy (bones/muscles/movements), biomechanics (stability/force summation/Netwon’s laws), physiology- be specific- what parts in particular?)
  • One sport that you would like to play for practical lessons.
energy systems

Energy Systems

Anaerobic & Aerobic

energy systems1
Energy Systems
  • Three pathways provide energy for physical activity.
    • Two are anaerobic (without oxygen) and the other is aerobic (with oxygen).
energy systems2
Energy Systems
  • The type of energy pathway used is dependent on the type of activity performed.
    • Activity that is longer in duration and of low intensity is fuelled by the aerobic energy system
    • Activity that is shorter in duration and of higher intensity is fuelled by the anaerobic energy systems
energy systems3
Energy Systems

Anaerobic

0-10 seconds: ATP-PC system

10 seconds- 2 minutes- Lactic acid system

2 minutes + Oxygen system - Aerobic

anaerobic energy systems sports
Anaerobic Energy Systems- Sports
  • Sports and activities that use this energy system include team sports such as;
    • Rugby
    • Netball
    • Soccer
  • where high intensity activity is performed for short periods of time.
anaerobic exercise
Anaerobic Exercise
  • Anaerobic exercise is defined as exercise performed at an intensity where a persons cardiovascular system cannot supply enough oxygen to keep up with demand and therefore energy is produced without the presence of O2.
lactic acid
Lactic Acid
  • Lactic acid is a bi-product of this energy production resulting in muscle soreness and will lead to a decrease in work intensity or a build up of lactate to the point where exercise can no longer continue.
anaerobic energy system key points
Anaerobic Energy System- Key Points
  • An – aerobic.
  • Anti- oxygen
  • Exercise performed

without oxygen.

  • Usually lasts for

around 0-2 minutes.

  • First 10 seconds include the ATP- CP system.
aerobic exercise
Aerobic Exercise
  • Aerobic exercise is defined as exercise performed at intensity when a persons cardiovascular system can supply enough oxygen to keep up with demand.
  • Examples include running, swimming and biking long distances.
