Studying the effect of intensity of exercise on fatigue

Equipment

stopwatch

Method

1. Perform some dynamic warm-up exercises on your non-dominant hand ('hand') to reduce the risk of muscle strain
2. Stretch your hand into the air above your head so that your arm is fully extended
3. Clench and unclench your hand at a frequency of one clench every two seconds
4. Record the time it takes for your hand to become completely fatigued - this is the point where it is too painful to continue
5. Rest the hand for two minutes
6. Repeat steps 2-5 but each time increase the frequency of clenching from one clench every two seconds to five clenches every two seconds in intervals of one clench every two seconds
7. Rest the hand for five minutes but each minute perform some static warm-down stretches on the hand
8. Repeat the entire process, steps 1-7, another two times to enable an average to be calculated
9. Perform some static warm-down stretches on the hand

Safety

The subject may develop muscle strain, so it is important that the warm-up and warm-down procedure is followed.

There are no other significant risks.
