Result Tables Table 1: Muscle Fatigue Data Trial Time (Seconds) Trial 1 128 Seconds Trial 2 104 Seconds Trial 3 91 Seconds Post-Lab Questions 1. Did you notice any changes in the amount of time you could perform each wall sit, or how your legs felt after each of the trials? 2. Explain the actions that were occurring at the molecular level to produce this movement. Include sources of energy and any possible effect of muscle fatigue. exercise is used you would feel some burning from the legs, and once the exercise is over, there is tightness coming from your legs and lower stomach. 3. Hypothesize what would happen if blood flow was restricted to the leg when this experiment performed. 4. How do banding patterns change when a muscle contract? 5. What is the difference between a muscle organ, a muscle fiber, myofibril, and a myofilament? 6. Outline the molecular mechanism for skeletal muscle contraction. At what point is ATP used and why? .
