The aim of this study was to examine the effects of upper-body graduated compression sleeves (CS) on neuromuscular and metabolic responses during a power training. Fifteen resistance trained men (age: 23.07 ± 3.92 years; body mass: 76.13 ± 7.62 kg; height: 177 ± 6 cm) performed 2 separate power training protocols, either wearing CS or placebo sleeves (PS), in a counterbalanced fashion. Participants first performed a familiarization session and a bench press 1 repetition maximum (1RM) test. The training protocol consisted of 6 sets of 6 repetitions of bench press with a load of 50% 1RM. Statistical analysis compared mean power, peak power, blood lactate, muscle activation, isometric strength, and repetitions to failure. Mean and peak power significantly (p ≤ 0.05) decreased with increasing sets. However, there was no significant difference (p > 0.05) on mean and peak power between protocols. Blood lactate clearance was also not significantly different (p > 0.05) between CS and PS. Muscle activation was not different between PRE and POST (p > 0.05) for any of the muscles analyzed. Isometric strength decreased from PRE to POST (p ≤ 0.05) and was not different between CS and PS. Repetitions to failure were not different between protocols (p > 0.05). These results demonstrate no positive performance effects when wearing graduated CS during power exercise in young trained men.
本研究的目的是检验上半身渐进式加压袖套（CS）在力量训练期间对神经肌肉和代谢反应的影响。15名进行过抗阻训练的男性（年龄：23.07±3.92岁；体重：76.13±7.62千克；身高：177±6厘米）以平衡的方式进行了2种单独的力量训练方案，分别穿着CS或安慰剂袖套（PS）。参与者首先进行了一次适应性训练和一次卧推1次重复最大值（1RM）测试。训练方案包括6组，每组6次重复的卧推，负荷为1RM的50%。统计分析比较了平均功率、峰值功率、血乳酸、肌肉激活、等长力量和重复至疲劳次数。平均功率和峰值功率随着组数增加而显著（p≤0.05）下降。然而，两种方案之间的平均功率和峰值功率没有显著差异（p>0.05）。CS组和PS组之间的血乳酸清除率也没有显著差异（p>0.05）。对于所分析的任何肌肉，训练前（PRE）和训练后（POST）的肌肉激活没有差异（p>0.05）。等长力量从训练前到训练后下降（p≤0.05），CS组和PS组之间没有差异。两种方案之间的重复至疲劳次数没有差异（p>0.05）。这些结果表明，年轻的受过训练的男性在进行力量训练时，佩戴渐进式CS并没有积极的表现效果。
