本研究的目的是探讨有氧训练、力量训练及其组合对非活动老年人关节活动度的影响。32名不活跃的老年男性(65-78岁)被分成四组(每组8人)：对照组(C)、力量训练组(ST)、心血管训练组(CT)和力量与有氧训练组(SA)。S组、A组和SA组的受试者每周训练三次，为期16周。ST包括10个主要肌群的阻力训练，强度为1-RM的55~80%，CT包括以最大心率的50~80%的步行/慢跑。训练前测量体重、身高、体力活动水平和最大摄氧量(VO(Over Dot)(2)-max)。在训练前和训练结束时评估等速(60和180°x秒(-1))和向心力量(卧位和腿部推举时为1-rm)。在训练前、训练8周和16周分别测定髋屈、伸、外展、内收、肩伸、屈、内收、屈膝、屈肘、坐伸评分，两组间V(Over Dot)O(2)max、体重、身高差异无统计学意义(p<；0.05)。ST和SA而不是CT和C在训练结束时增加了等速力量和向心力量(p<；0.05)。ST和SA在训练中期和训练后均显著提高(p<；0.05)坐前屈、屈肘、屈膝、肩屈伸和髋屈伸。CT仅在训练后髋关节屈曲和伸展时增加(p<；0.05)。结果表明，阻力训练可能能够增加一些不活跃的老年人的关节的活动范围，可能是由于肌肉力量的改善。
The purpose of this study was to investigate the effects of aerobic training, strength training and their combination on joint range of motion of inactive older individuals. Thirty-two inactive older men (65 - 78 yr) were assigned to one of four groups (n = 8 per group): control (C), strength training (ST), cardiovascular training (CT), and combination of strength and aerobic training (SA). Subjects in the S, A, and SA trained three times a week for 16 weeks. ST included 10 resistance exercises for the major muscle groups at an intensity of 55-80% of 1-RM and CT included walking/jogging at 50-80% of maximal heart rate. Body weight and height, physical activity level and maximal oxygen uptake (VO(over dot)(2)-max) were measured before the training period. Isokinetic (60 and 180 deg x sec(-1)) and concentric strength (1-RM in bench and leg press) were assessed prior to and at the end of the training period. Hip flexion, extension, abduction, and adduction, shoulder extension, flexion, and adduction, knee flexion, elbow flexion and sit-and-reach score were determined before and at 8 and 16 weeks of training, There were no differences between groups in V(over dot)O(2)max, body weight, and height (p < 0.05). ST and SA but not CT and C increased isokinetic and concentric strength at the end of the training period (p < 0.05). ST and SA increased significantly (p < 0.05) sit-and-reach performance, elbow flexion, knee flexion, shoulder flexion and extension and hip flexion and extension both at mid- and post-training. CT increased (p < 0.05) only hip flexion and extension at post training. Results indicate that resistance training may be able to increase range of motion of a number of joints of inactive older individuals possibly due to an improvement in muscle strength.
