High antagonist muscle activation in elderly men limits movement efficiency and may contribute to reduced power output.
Older adults often have higher antagonist muscle activity, which can reduce movement efficiency. Training that focuses on smooth, controlled movements and reducing unnecessary tension in opposing muscles may help improve power output and functional performance.
High antagonist muscle activity may limit the full movement efficiency depending on the type of muscle action, testing conditions and the velocity and/or the time duration of the action, especially in the elderly.
Why this rating
EMG data clearly shows higher antagonist activation in elderly groups with statistical significance.

- Maximal power output in the upper extremity is optimized at loads of 30-45% of one-repetition maximum (1RM), whereas maximal power in the lower extremity is optimized at loads of 60-70% of 1RM.Good
- Age-related declines in explosive strength and power are greater than the declines in maximal isometric strength.Good
