Several studies have been carried out in order to evaluate the potential influence of increased physical activity on the health, biological ageing and functional ability of the elderly. However, only limited information is available on the effects of multicomponent training and detraining on functional performance.
The purpose of the present study was to investigate the effect of 8-month multicomponent training and 3-month detraining on the functional fitness of older women.
Fifty-seven women were randomly assigned to an exercise (n = 32; 68.4 +/- 2.93 years) or a control group (n = 25; 69.6 +/- 4.20 years). The training program consisted of 2 sessions per week of aerobic, strength, balance and flexibility exercises. The functional fitness test battery was performed to assess the physical parameters associated with independent functioning in older adults.
No significant changes were observed in body mass index and cardiovascular endurance as a result of the exercise training. Training induced significant (p < 0.05) improvements in chair stand (27.3%), arm curl (17.4%), chair sit-and-reach (17.4%), up-and-go (11%) and back scratch (14.5%) tests. However, both upper and lower body strength and upper and lower flexibility declined significantly after detraining in the exercise group.
The results of this study highlight the negative effects of interrupting exercise on several physical parameters of functional fitness.
为了评估增加体育活动对老年人健康、生物衰老和功能能力的潜在影响,已经开展了多项研究。然而,关于多组分训练和停训对功能表现的影响,目前仅有有限的信息。
本研究的目的是调查8个月的多组分训练和3个月的停训对老年女性功能体能的影响。
57名女性被随机分为运动组(n = 32;68.4 +/- 2.93岁)或对照组(n = 25;69.6 +/- 4.20岁)。训练计划包括每周进行2次有氧、力量、平衡和柔韧性练习。进行功能体能测试组来评估与老年人独立功能相关的身体参数。
运动训练后,体重指数和心血管耐力未观察到显著变化。训练使坐立试验(提高27.3%)、手臂弯举试验(提高17.4%)、坐位体前屈试验(提高17.4%)、起立行走试验(提高11%)和背部伸展试验(提高14.5%)有显著(p < 0.05)改善。然而,运动组停训后,上、下肢力量以及上、下肢柔韧性均显著下降。
本研究结果突出了中断运动对功能体能的几个身体参数的负面影响。
