Older adults use a unique strategy to lift inertial loads with the elbow flexor muscles.
Strength training improves the steadiness of slow lengthening contractions performed by old adults. Effect of grip span on maximal grip force and fatigue of flexor digitorum superficialis. Electrode placement is not responsible for the divergent increases in EMG and force with strength training. Motor unit synchronization reduces the steadiness of anisometric contractions by a hand muscle.
