We dissected the gastrocnemius from a frog and ran some experiments on it. This experiment was incrementally increasing the stimulus voltage to see the response in tension. I know this is because the threshold is not reached, but I don't know how to explain this physiologically?

Activity 2 - Twitch Contractions and Summation [PowerPhys]
I got 100% on this but it took a while to do this report. I hope it helps those that want to understand better this type of contractions. Think before copying it. The best way to learn something is to understand it and make it meaningful. Have a great day!!
Muscle physiology- if injury was responsible for the development of soreness
In a fitness test a subject repeatedly stepped up using the right leg while the left leg was used to oppose the effect of gravity in the step down. Muscle pain was experienced several hours after the test. The soreness reached a peak in 1 to 2 days and persisted for about a week. The presences of proteins specific for muscle in the subject’s serum provided evidence for muscle cell i
