The purpose of the present study was to investigate the effect of two different resistance training (RT) prescription methods on phase angle (PA) in older women. Seventy-six older women (68.5 ± 5.7 years) were randomly assigned to one of three groups: two training groups that performed an eight-week RT programme either in a constant load (CT, n = 25) or an ascending pyramidal load (PR, n = 26) routine three times per week, or a control group (CG, n = 25) that performed no exercise. The CT programme consisted of three sets of 8-12 repetition maximum (RM) with a constant load for the three sets, whereas the PR training consisted of three sets of 12/10/8 RM with incremental loads for each set. PA was assessed by whole-body spectral bioelectrical impedance. After the RT period, both CT and PR achieved higher (P < .05) values of PA (CT = 5.76 ± 0.59°, PR = 5.63 ± 0.61°, CG = 5.48 ± 0.46°) compared to the CG; however, there was no difference (P > .05) between trained groups. The results suggest that eight weeks of RT based on a PR and CT load routines promote an improvement in PA, and both prescription methods performed similarly.
本研究的目的是调查两种不同的阻力训练(RT)处方方法对老年女性相位角(PA)的影响。76名老年女性(68.5±5.7岁)被随机分配到三组中的一组:两个训练组,一组进行为期八周的RT计划,采用恒定负荷(CT,n = 25)或递增金字塔负荷(PR,n = 26)常规,每周进行三次;另一组为对照组(CG,n = 25),不进行任何运动。CT计划包括三组,每组进行8 - 12次最大重复次数(RM),且三组负荷恒定;而PR训练包括三组,每组分别进行12/10/8 RM,每组负荷递增。通过全身频谱生物电阻抗评估PA。在RT期结束后,与CG组相比,CT组和PR组的PA值均更高(P < 0.05)(CT = 5.76±0.59°,PR = 5.63±0.61°,CG = 5.48±0.46°);然而,训练组之间没有差异(P > 0.05)。结果表明,基于PR和CT负荷常规的八周RT可促进PA的改善,且两种处方方法的效果相似。
