摘要: Severe ankle injuries can require extended periods of immobilization that adversely affect the strength muscles. We have investigated a single-leg training program muscles surrounding to determine if it produces crossover benefit for contralateral Twenty subjects without any history were randomly divided into control and group. Both groups underwent isokinetic testing at beginning end an 8-week period. The group maintained normal activities between tests. Half trained dominant leg only other half nondominant period, three times per week. who improved peak torque values by 8.5% in 1.5% untrained leg. Similarly, 9.3% 3.5% In contrast, showed no significant change torque, power, or endurance initial final With improvements as high 40% 19% eccentric inversion, this technique deserves further investigation injured population where benefits may be more substantial.
