The first part of the muscle function lab I had to what effects Ice cold H2O had on my muscles. To do this I made an ice bath in a bucket of water. The first set of fists that I made was at normal room temperature. I then submerge my hand in to the bucket of ice and let it sit for one minute. The results were a little different then I thought.
Room temperature- 47
One minute in Ice Bath- 32
The second part of the lab was making the same fist but I recorded what my fatigue was over ten sets. This time I was more on with my hypothesis. I knew that I would get fatigued and felt that amount to times I could make a fist would get smaller with each set.

What are the three changes you observed in a muscle while it is working (contracted)?
1- My muscles became weaker and fatigued with each set.
2- I noticed my veins getting larger and bulging.
3- I also felt tightness in my joints slowing down the squeezing.
What effect did the cold temperature have on the action of your hand muscles? Explain.
The Ice bath had an effect of slowing down the cellular metabolism and thus my fist became weak and slow. With the vasoconstriction from the cold along with the tightness of my joints it was very hard and I had to push myself. I think a lot of this lab has to do with your mind set, and you can overcome the fatigue and weakness to a point.
