Effects of exercise on the muscles
- Short Term Effects
- Increase in muscle temperature
- Due to the chemical reactions producing heat.
- Warms up your muscles
in preparation for
exercise.
- Reduces chances of injury.
- Due to the chemical reactions producing heat.
- Fatigue
- Ability to use oxygen is
less efficient.
- Muscles demand more
oxygen to finction.
- Ability to use oxygen is
less efficient.
- Build up of lactic acid
- Due to oxygen debt.
- Stored on the working muscles.
- Causes fatigue.
- During aerobic respiration.
- Due to oxygen debt.
- Glycogen stores released
- In the muscles from the liver.
- Causes increase in glucose levels.
- Increases energy availability.
- In the muscles from the liver.
- Increased demand for oxygen
- More oxygen is needed
to produce glucose.
- Can cause and oxygen debt.
- More oxygen is needed
to produce glucose.
- Increase in muscle temperature
- Long Term Effects
- Muscular Hypotrophy
- Only with training.
- Muscles get bigger and stronger.
- Requires sustained exercise.
- Requires adequate rest.
- Beneficial in weightlifting
to help lift heavier weights
with ease and outlift
competitors.
- Only with training.
- Improved muscular endurance
- Requires sustained exercise.
- Allows muscles to work for
longer without fatigue.
- Beneficial in long distance
events as fatigue is offset for
longer, allowing the runner to
work harder for longer.
- Requires sustained exercise.
- Strengthening of areas around joints
- Such as tendons.
- Decreases risk of injury.
- Allows harder training sessions.
- Such as tendons.
- Increased myoglobin stores
- Gives more protein to the muscles.
- Aids the
transportation of
oxygen.
- Benefits marathon runners, better
supply of oxygen to the muscles
offsetting the chance of oxygen debt
and lactic acid.
- Gives more protein to the muscles.
- Muscular Hypotrophy
