A study of optimal handle shape and muscle strength distribution on lower arm when holding a foil.
The strength of five working muscle groups of the lower arms of 8 male fencers, including adductor pollicis, extensor carpi radialis, flexor carpi radialis, extensor carpi ulnaris, and flexor carpi ulnaris, were examined during competition. Root mean square values of muscular electromyographic signals indicated that the shape of foil handles significantly influenced distribution of working strength of each muscle group. Use of the Pistol-Viscounti type of foil handle showed better distribution of strength among the 5 muscle groups than did other types of foils. Using the Pistol-Viscounti foil handle not only reduced muscular fatigue but also lessened cumulative trauma symptoms while holding a foil for a long duration.
