Six children, three with cerebral palsy and three with myelomeningocele, participated in a progressive, 8-week, circuit muscular strength training program. The program was designed to improve wheelchair propulsion, an important functional outcome. Subjects performed three sets of six-repetition maximum (6-RM) upper body strength exercises, three times a week. Exercises included shoulder flexion, extension, abduction, internal and external rotation, elbow flexion, extension, and shoulder flexion/elbow extension (bench press). Subjects exercised quickly with little rest between each set for approximately 30 minutes per session. All children used wheelchairs extensively and participated in a 50-m, and a 12-minute wheelchair propulsion test before and after the 8-week program. The sign test was used to determine if statistically significant (P < or = .05) wheelchair propulsion or 6-RM changes occurred over the training period. Subjects improved significantly (P < or = .031) in all muscular strength (6-RM) measures and the 12-minute distance test. There was a trend toward improvement in the 50-meter test, although this change was not significant (P < or = .05). The results indicate that progressive resistance exercise training seems to improve muscular strength and wheelchair performance in selected disabled children.
六名儿童参与了一项为期8周的渐进式循环肌肉力量训练计划，其中三名患有脑瘫，三名患有脊髓脊膜膨出。该计划旨在改善轮椅推进能力，这是一项重要的功能指标。受试者每周进行三次上肢力量练习，每组进行六次重复的最大重量（6-RM），共三组。练习包括肩部屈曲、伸展、外展、内旋和外旋、肘部屈曲、伸展以及肩部屈曲/肘部伸展（卧推）。受试者每组练习之间休息时间很短，快速完成练习，每次训练约30分钟。所有儿童都大量使用轮椅，并在8周训练计划前后分别参加了50米和12分钟的轮椅推进测试。使用符号检验来确定在训练期间轮椅推进能力或6-RM是否发生了具有统计学意义（P≤0.05）的变化。受试者在所有肌肉力量（6-RM）指标和12分钟距离测试中均有显著改善（P≤0.031）。50米测试有改善的趋势，尽管这一变化不显著（P≤0.05）。结果表明，渐进性抗阻运动训练似乎能改善特定残疾儿童的肌肉力量和轮椅使用表现。
