Muscle Fiber Contraction and Relaxation 

Step 2: Analyze 

Study the hypothetical case scenario below.

It is the beginning of a new football season. After a break from sports and workouts, Samson is excited about playing for his new club. His first training session with his coach was good. Samson pushed himself beyond his endurance limit to impress Coach Fredrick. He engaged in various activities, including a 200-meter race, intense cardio training, and an hour of weight lifting. Everything was fine with Samson until two days after his training session when he started experiencing soreness, aches, and painful sensation in muscles around his shoulder, thigh, and calf.

Step 3: Respond

Prepare a 500- 600 word assessment describing the process involved in muscle soreness. Consider the following points:

• Describe the sequence of events involved in a muscle contraction.
• Explain muscle contraction and the metabolic changes that occur in the muscle during contraction.
• Explain muscle relaxation and the metabolic changes that occur in the muscle during relaxation.
• Describe the relationship between muscle metabolism and muscle fatigue.
