Muscle hypertrophy is associated with a ________________ in electromyography.
- A.
Increase
- B.
Decrease
- C.
No change
Correct Answer
A. IncreaseExplanation
Muscle hypertrophy is associated with an increase in electromyography (EMG) activity. EMG measures the electrical activity produced by skeletal muscles. When muscles undergo hypertrophy, which is the enlargement of muscle cells, there is typically an increase in muscle fiber size and overall muscle mass. This increase in muscle size is often accompanied by an increase in electrical activity, as larger muscles generally produce stronger and more coordinated contractions, leading to higher EMG readings.Rate this question:
