Soc19- Short Term Effects Of Exercise

Question 1

Effects on the muscles:

Answer 1

• Muscle fatigue is when you exercise- your muscles can feel weak, painful and tired.
• This occurs as a result of anaerobic (no oxygen) respiration.
• If there is no oxygen available for respiration - we produce lactic acid, this process is known as ‘lactate accumulation.
• Cramps are a severe sort of muscle fatigue, which causes the muscles to contract in a painful way.

Question 2

Effects on the heart:

Answer 2

• When you exercise your heart beats faster- your heart rate is the number of times your heart beats per minute.
• A trained athlete is likely to have a lower resting heart rate than someone who is untrained.
