Anatomy and physiology: the short and long term effects of exercise
Study Hub
Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit will explore the immediate responses our bodies make to cope with the effects of exercise as well as the longer term adaptations it makes in response to training that enable us to cope better with exercise and improve performance.
Lesson Summary
You will learn to demonstrate your understanding of how the body responds to different types of exercise and how to optimise recovery.
Key Notes
- Immediate effects of exercise include sweat, red skin, increased rate and depth of breathing, and increased heart rate.
- Methods to recover from exercise include an active cool down, manipulating diet and using ice baths or massage.
- Anaerobic exercise results in oxygen debt and the build up of lactic acid that needs to be replenished during recovery.
Vocabulary To Learn
- intensity: how hard you are working
- recovery: various strategies, such as nutrition, hydration and adequate rest are employed to optimise future performance and minimise fatigue and injury risk
- oxygen debt: the amount of extra oxygen required to remove the lactic acid and replace the body's reserves of oxygen
- lactic acid: a by-product of anaerobic respiration that accumulates in muscles during intense exercise, contributing to muscle fatigue and soreness
Common Mistakes To Avoid
- A proper cool down speeds up reduction in heart rate after exercise and prevents muscle soreness.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Immediate effects of exercise include sweat, red skin, increased rate and depth of breathing, and increased heart rate. Methods to recover from exercise include an active cool down, manipulating diet and using ice baths or massage.
2. What does this key word mean in this lesson? 'intensity'
how hard you are working.
3. Correct this common mistake.
Mistake: A proper cool down speeds up reduction in heart rate after exercise and prevents muscle soreness. Correction: An active cool down actually prolongs the elevated heart and breathing rate after exercise to help flush fresh oxygen through the muscles and improve recovery. However, DOMS may still occur due to microtears in muscles if training was intense.
