Question

1. Please provide a mechanistic basis for the decrease in the amount of force generated by the contracting muscle with time.

2. What are possible causes of gender differences in muscle strength and the potential difference in the time to peak force and onset of fatigue

3. Postulate on the possible causes and potential advantages of the differences in the force generation by different muscle finger types

4. What is the overall force differential between the dominant and the non-dominant hands? How does this differ between males and females

Answer 1

Question no 1

The amount of force generated will decrease over time as fatigue of the muscle occur .

Fatigue is the decrease of muscle activity due to repetition of stimulali . As a resul if energy depletion as well as fatigue of the nerves that carry the stimulali this condition occur .

This is the fatigue curve of muscle and main reason for fatigue are

1. Lack of nutrients like glucose
2. Lack of O2
3. Ach exhaustion in endplate
4. Accumulation of lalctic acid and phosphoric acid
