目的:探究阳极经颅直流电刺激(a-tDCS)结合抗阻训练对健康成年人下肢力量和无氧功率的训练效果。方法:选取30名有丰富抗阻训练经验的(19.70±1.47)岁健康成年人,并随机分配到复合训练组(a-tDCS+抗阻训练,n=15)和单一训练组(n=15);2组受试者每周均进行2次颈后杠铃深蹲训练,复合训练组需要在每次深蹲训练前进行20 min a-tDCS(电流2mA)干预,训练时长为5周;采用双因素重复测量方差分析(干预方式×测试阶段),探讨上述自变量对受试者的下肢最大力量和无氧功率指标的影响,包括峰值功率(PP)、平均功率(AP)以及功率衰减(PD)。结果:5周训练干预后,2组受试者后测的1RM深蹲成绩相较前测均有显著提高(p<0.05),且复合训练组受试者1RM深蹲成绩的提高效果显著于单一训练组〔复合训练组(19.20±7.38) kg对比单一训练组(12.27±8.66) kg,p<0.05〕;复合训练组和单一训练组的PP、AP、PD在干预前后的差异均不显著(p>0.05)。结论:a-tDCS结合抗阻训练对下肢肌力的增强作用显著于单一抗阻训练,a-tDCS可以作为健康成年人增强下肢力量的一种辅助训练方法。

Objective: To investigate the effects of transcranial direct current stimulation (a-tDCS) combined with squat training on lower limb strength and anaerobic power in healthy adults. Methods: Thirty adults with extensive resistance training experience were selected to undergo two interventions randomly. composite training group (a-tDCS + resistance training, n=15) and single resistance training group (n=15). Both groups performed back barbell squat training twice a week for 5 weeks. The combined training group received 20-minutes a-tDCS intervention (current: 2mA) before each squat training session. A two-factor repeated-measures analysis of variance (intervention mode × test time) was used to compare the differences in squat 1 repetition maximum (1 RM) and lower extremity anaerobic work metrics, including peak power (PP), average power (AP), and power decline (PD), before and after interventions. Results: 1) After the 5-week training intervention, the 1RM performance of both groups was significantly improved compared with the pre-test (p<0.05), and the improvement of in 1RM squat performance in the composite training group was significantly better than that of the single training group (p<0.05); 2) no differences of PP, AP, FI between the pre and post-tests of the two groups were found to reach the level of significance (p>0.05). Conclusions: a-tDCS combined with resistance training is more effective in enhancing lower limb muscle strength than resistance training alone and a-tDCS can be used as an auxiliary training method to efficiently improve lower limb maximal strength in healthy adults.
