Short Term (Acute) Physiological Responses to ExerciseEffects that take place while we are exercising…
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
BRAINSTORM
Thinking about the 1 minute of exercise you just did- What effects did you feel taking place within your body?
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
•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”
• 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”
• Increase in the number of breaths per minute
(respiratory rate)
• Increase in the amount of air taken in each breath.
(tidal volume)

Short Term Effects of Exercise- Summary•Muscular System▫ Increased temperature

Long Term (Chronic) Physiological Responses to Exercise
Effects that take place following exercise weeks, months, years later…
Body Systems•Muscular system
•Cardiovascular/ Circulatory system
•Respiratory system
BRAINSTORM
Think about the effects of training on the body. Try to link your answer to the three energy systems.
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•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•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•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
•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.
Body system Short term response to exercise
Long term response to exercise
Muscular• Muscles receive more
blood and oxygen• Muscles increase in
temperature• Muscles become more
flexible
• Muscles get larger and stronger• Muscles become more flexible• Muscles get more blood• Vessels can receive more
oxygen
Cardiovascular
• The blood is able to carry more oxygen
• Heart beat increases• More blood pumped
around body
• The blood is able to carry more oxygen
• The heart gets larger• Resting heart rate gets lower• Heart rate returns to normal
faster• Exercise heart rate gets lower
Respiratory• Breathing rate increases• Amount of air taken in each
breath increases
• The lungs can breathe in and out a greater volume of air, and with
it oxygen
Sticky Notes1. One thing you do not understand fully from the last
two lessons (short term & long term effects of exercise).
2. 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?)
3. One sport that you would like to play for practical lessons.

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

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 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 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•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 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.
