This study investigated the effects of biset, drop-set and traditional resistance training (RT) techniques on metabolic responses in resistance-trained males. Fifteen trained males (age 29.7 ± 6.1 years; body mass 83.4 ± 7.6 kg; RT experience 11.4 ± 6.7 years; one-repetition maximum (1RM) barbell bench press: body mass ratio 1.4 ± 0.1 a.u.) were assigned to three experimental conditions, in a randomized crossover design. The experimental conditions were bi-set (3×10 repetitions at 70%1RM in barbell bench press followed by 10 repetitions at 60%1RM in incline bench press), drop-set (3×10 repetitions at 70%1RM followed by 10 repetitions at 50%1RM in barbell bench press) and traditional RT (3×20 at 60%1RM in barbell bench press). A portable gas analyzer was used to assess energy expenditure and maximal oxygen uptake during the experimental protocols. Blood lactate levels were assessed at baseline and 1, 3, and 5 minutes after the training session. There were no differences for total training volume ( = 0.999). Post hoc comparisons revealed that bi-set elicited higher aerobic energy expenditure ( = 0.003 vs. drop-set; < 0.001 vs. traditional RT) and aerobic oxygen consumption ( = 0.034 vs. drop-set; < 0.001 vs. traditional RT) than other RT schemes. There were no differences regarding anaerobic EE between-conditions ( > 0.05). There was a main effect of time and condition for blood lactate levels ( < 0.001). Post hoc comparisons revealed that drop-set training elicited higher blood lactate levels than traditional RT ( = 0.009). The results suggest that RT techniques may have a potential role in optimizing metabolic responses in resistance-trained males.
本研究调查了双组训练、递减组训练和传统抗阻训练（RT）技术对经过抗阻训练男性代谢反应的影响。15名经过训练的男性（年龄29.7±6.1岁；体重83.4±7.6千克；抗阻训练经验11.4±6.7年；杠铃卧推一次最大重复量（1RM）与体重之比为1.4±0.1任意单位）采用随机交叉设计被分配到三种实验条件。实验条件分别为双组训练（杠铃卧推70%1RM进行3组，每组10次重复，随后上斜卧推60%1RM进行10次重复）、递减组训练（杠铃卧推70%1RM进行3组，每组10次重复，随后50%1RM进行10次重复）和传统抗阻训练（杠铃卧推60%1RM进行3组，每组20次重复）。在实验方案期间，使用便携式气体分析仪评估能量消耗和最大摄氧量。在基线以及训练后1、3和5分钟评估血乳酸水平。总训练量无差异（P = 0.999）。事后比较显示，与其他抗阻训练方案相比，双组训练引起更高的有氧能量消耗（与递减组训练相比，P = 0.003；与传统抗阻训练相比，P < 0.001）和有氧耗氧量（与递减组训练相比，P = 0.034；与传统抗阻训练相比，P < 0.001）。不同条件之间的无氧能量消耗无差异（P > 0.05）。血乳酸水平存在时间和条件的主效应（P < 0.001）。事后比较显示，递减组训练引起的血乳酸水平高于传统抗阻训练（P = 0.009）。结果表明，抗阻训练技术可能在优化经过抗阻训练男性的代谢反应方面具有潜在作用。
