目的：研究主动伸展计划对老年女性膝关节屈肌的柔韧性、扭矩和功能活动度的影响。这项研究的假设是，主动屈膝肌伸展计划增加了灵活性和肌肉扭矩，并改善了功能活动。设计：12名年龄为68.3+/-6.2岁的活跃老年女性参与了这项持续12周的研究。本研究分为三个阶段(A(1)-B-A(2))，每个阶段持续4周。A阶段(1)和A(2)为对照阶段(无干预)，B阶段(伸展)包括7次主动屈膝肌伸展(每次1min，休息30秒，每周两次)。通过测量膝关节伸展运动范围、“计时起跳”测试和60度/秒的测力测试，评估膝关节的灵活性、功能性和等速扭矩(膝关节屈肌和伸肌)。结果：伸展增加了膝关节屈肌的柔韧性(41.5%；P=0.0001)、屈膝扭矩(11.40%)和伸肌扭矩(10.1%)(P<0.05)。
Objective: To investigate the effect of an active stretching program on the knee flexors with regards to flexibility, torque, and functional mobility of older women. The hypothesis of this study was that a program of active knee-flexor stretching increases flexibility and muscle torque and improves functional mobility.Design: Twelve active older women aged 68.3 +/- 6.2 yrs participated in this study, which lasted 12 wks. This study was divided into three phases (A(1)-B-A(2)), each lasting 4 wks. Phases A(1) and A(2) were control phases (without intervention), and phase B (stretch) consisted of seven repetitions of active knee-flexor stretching (1 min each, 30-sec rest, twice a week). Flexibility, functionality, and isokinetic torque (knee flexors and extensors) were assessed by measuring the knee-extension range of motion, the "Timed Up & Go" test, and by a dynamometry test at 60 degrees/sec.Results: Stretching increased the flexibility of the knee flexors (41.5%; P = 0.0001), knee-flexor torque (11.40%), and extensor torque (10.1%) (P
