To analyze the effects of whole body electrostimulation (WB-EMS) with body weight training on functional fitness and body composition of older men. Twenty physically inactive older men were randomized into: Control group (control), performed the body weight exercise training wearing electrostimulation clothing, but without receiving electrical current stimuli ( = 10), and body weight associated with whole body electrostimulation group (BW+WB-EMS), performed the body weight exercise training wearing electrostimulation clothing plus whole body electrostimulation ( = 10). The training sessions were performed twice a week for 6 weeks and included eight exercises using body weight, performed in two sets of eight repetitions. Physical function was assessed using a battery composed of seven tests, six derived from the Senior fitness test and a handgrip strength test. We also measured the muscle thickness (MT) of the biceps and triceps brachii and vastus lateralis. The BW+WB-EMS group presented increased ( < 0.05) performance in the 30-s chair stand test (10.2 ± 3.3 vs. 13.8 ± 5.0 reps), arm curl (16.6 ± 3.9 vs. 19.9 ± 6.1 reps), 6-min walk test (402 ± 96 vs. 500 ± 104 m), and handgrip strength test (30 ± 11 vs. 32 ± 11 kgf). The BW+WB-EMS group also presented increased MT ( < 0.05) in the biceps brachii (17.7 ± 3.0 vs. 21.4 ± 3.4 mm), triceps brachial (14.7 ± 3.6 vs. 17.5 ± 4.1 mm), and vastus lateralis muscles (15.1 ± 2.6 vs. 18.6 ± 4.3 mm). Moderate correlations were found in arm curl ( = 0.011, = 0.552) but not handgrip strength ( = 0.053, = 0.439) with changes in the biceps MT. Moderate changes in the 6-min walk distance were significantly correlated with changes in vastus lateralis MT ( = 0.036, = 0.471). There was a moderate correlation between the changes in the 30-s chair stand test ( = 0.006, = 0.589) and changes in the vastus lateralis MT. Furthermore, although a moderate correlation ( = 0.438) was found between triceps MT and handgrip strength no significant difference ( = 0.053) was reported. Additionally, there were no statistical differences in any parameters for the control group. WB-EMS with body weight training increased functional fitness and MT in physically inactive older men.
分析全身电刺激（WB - EMS）结合体重训练对老年男性功能适应性和身体成分的影响。20名身体活动不足的老年男性被随机分为：对照组（control），穿着电刺激服装进行体重锻炼训练，但不接受电流刺激（n = 10），以及体重结合全身电刺激组（BW + WB - EMS），穿着电刺激服装并进行全身电刺激的同时进行体重锻炼训练（n = 10）。训练课程每周进行两次，共6周，包括八项利用体重的练习，分两组进行，每组八次重复。使用由七项测试组成的一套测试来评估身体功能，其中六项源自老年健身测试，还有一项握力测试。我们还测量了肱二头肌、肱三头肌和股外侧肌的肌肉厚度（MT）。BW + WB - EMS组在30秒椅子站立测试（10.2 ± 3.3次与13.8 ± 5.0次重复）、手臂弯举（16.6 ± 3.9次与19.9 ± 6.1次重复）、6分钟步行测试（402 ± 96米与500 ± 104米）以及握力测试（30 ± 11千克力与32 ± 11千克力）中的表现有所提高（P < 0.05）。BW + WB - EMS组的肱二头肌（17.7 ± 3.0毫米与21.4 ± 3.4毫米）、肱三头肌（14.7 ± 3.6毫米与17.5 ± 4.1毫米）和股外侧肌（15.1 ± 2.6毫米与18.6 ± 4.3毫米）的MT也有所增加（P < 0.05）。在手臂弯举中发现中度相关性（r = 0.011，P = 0.552），但在握力与肱二头肌MT变化之间未发现相关性（r = 0.053，P = 0.439）。6分钟步行距离的中度变化与股外侧肌MT变化显著相关（r = 0.036，P = 0.471）。30秒椅子站立测试的变化与股外侧肌MT变化之间存在中度相关性（r = 0.006，P = 0.589）。此外，虽然在肱三头肌MT与握力之间发现了中度相关性（r = 0.438），但未报告显著差异（P = 0.053）。此外，对照组在任何参数上均无统计学差异。全身电刺激结合体重训练可提高身体活动不足的老年男性的功能适应性和肌肉厚度。
