ANALYSIS OF DATA:
1. What are the three changes you observed in a muscle while it is working (contracted)?
- Noticed a few things:
1. The circumference is larger then when it is relaxed.
2. The more it is used the faster it become fatigued
3. The more you used the muscle it began to hurt after a little while!
2. What effect did the cold temperature have on the action of your hand muscles? Explain.
-The cold had a great deal of effect on the hand muscles. It made the muscles tighter and achier when you tried to flex. It was almost like they didn’t want to work any longer!
But after the try the hand became numb and I was able to flex it a little faster.
3. In Figure 3, make a line graph of your results of the fatigue experiment. Be sure to fill in the values on the vertical axis.
4.What effect did fatigue have on the action of your hand muscles? Explain.
- It began to hurt and achy after each attempt it also slowed down dramatically but after then hand became numb it started to pick up speed again! But after my hand started to “thaw” then I could feel the pain again!
