Abstract:
UNASSIGNED: McMahon, G. No effect of interset palm cooling on acute bench press performance, neuromuscular or metabolic responses, following moderate-intensity resistance exercise. J Strength Cond Res 38(7): 1213-1220, 2024-Despite the growing literature in high-intensity exercise regarding palm cooling, the acute effects of palm cooling on exercise performance indices, neuromuscular and metabolic responses, have not been described during moderate-intensity resistance exercise. Nine (age, 22 ± 1 year; mass, 80.8 ± 16.2 kg; height, 1.80 ± 0.11 m) healthy, male (n = 7) and female (n = 2) resistance-trained subjects performed 4 sets of bench press to failure at 60% 1 repetition maximum with 3-minute passive recovery. Subjects were randomly allocated to either the cooling (COL; 2 minutes of cooling at 10 °C) or the control (passive rest; CON) condition separated by 1 week between the conditions. Exercise performance (volume load, repetitions, barbell velocity), muscle activation, blood lactate, and rate of perceived exertion were assessed. Despite changes across the variables during the resistance exercise sessions, there were no statistical differences (p > 0.05) in any of the performance, neuromuscular or physiological responses, between the 2 experimental conditions, despite palm temperature being significantly (p < 0.001) reduced in the cooling condition compared with control throughout. Therefore, based on the results of this study, palm cooling does not enhance acute moderate-intensity resistance exercise.

■麦克马洪,G.插入手掌冷却对急性台式压力机性能没有影响,神经肌肉或代谢反应,在中等强度的阻力运动之后。JStrengthCondRes38(7):1213-1220,2024-尽管有关手掌冷却的高强度运动的文献越来越多,手掌降温对运动性能指标的急性影响,神经肌肉和代谢反应,在中等强度的阻力运动中没有被描述。九(年龄,22±1年;质量,80.8±16.2kg;高度,1.80±0.11米)健康,男性(n=7)和女性(n=2)抵抗训练的受试者以60%1的最大重复次数进行了4组卧床,并进行了3分钟的被动恢复。将受试者随机分配到冷却(COL;在10°C下冷却2分钟)或对照(被动休息;CON)条件,这些条件之间间隔1周。运动性能(体积负载,重复,杠铃速度),肌肉激活,血乳酸,并评估了感知的劳累率。尽管在抵抗运动期间变量发生了变化,各项表现均无统计学差异(p>0.05),神经肌肉或生理反应,在两个实验条件之间,尽管在冷却条件下与对照组相比,棕榈温度显着降低(p<0.001)。因此,根据这项研究的结果,手掌冷却不会增强急性中等强度的阻力运动。
