背景。本研究的目的是比较老年人最大等速仅偏心阻力训练与仅最大等速或最大等速向心阻力训练引起的自愿力量（等长、向心和偏心）和功能活动度的变化。方法。 12 名女性（73 +/- 7 岁）和 18 名男性（73 +/- 5 岁）使用 Biodex System 3 测力计完成了为期 12 周的训练计划（每周 3 次）。主要结果指标包括峰值等长和等速（同心和偏心）膝伸肌力量、同心功、同心力、上下楼梯以及步态速度。参与者被随机分配到三个训练组之一：仅等长训练组、仅等速向心训练组或仅等速偏心训练组。结果。经过 12 周的训练后，所有三个训练组均表现出峰值等长和等速向心和偏心力量的增加（p
Background. The aim of the present study was to compare the changes in voluntary strength (isometric, concentric, and eccentric) and functional mobility in response to maximal isokinetic eccentric-only resistance training to those elicited by maximal isometric-only or maximal isokinetic concentric-only resistance training in older adults.Methods. Twelve women (73 +/- 7 years) and 18 men (73 +/- 5 years) completed a 12-week training program (three times per week) using a Biodex System 3 dynamometer. Primary outcome measures included peak isometric and isokinetic (concentric and eccentric) knee extensor strength, concentric work, concentric power, stair ascent and descent, and gait speed. Participants were randomly assigned to one of three training groups: isometric-only, isokinetic concentric-only, or isokinetic eccentric-only.Results. All three training groups demonstrated an increase in peak isometric and isokinetic concentric and eccentric strength following 12 weeks of training (p
