This study aimed to compare the mechanical (lifting velocity and maximum number of repetitions), physiological (muscular activation, lactate, heart rate, and blood pressure), and psychological (rating of perceived exertion) responses to upper-body pushing exercises performed wearing a sports elastomeric garment or a placebo garment. Nineteen physically active young adults randomly completed two training sessions that differed only in the sports garment used (elastomeric technology or placebo). In each session, subjects performed one set of seated shoulder presses and another set of push-ups until muscular failure. The dependent variables were measured immediately after finishing the set of each exercise. Compared to the placebo garment, the elastomeric garment allowed participants to obtain greater muscular activation in the pectoralis major (push-ups: = 0.04, = 0.49; seated shoulder press: < 0.01, = 0.64), triceps brachialis (push-ups, < 0.01, = 0.77; seated shoulder press: < 0.01, = 0.65), and anterior deltoid (push-ups: < 0.01, = 0.72; seated shoulder press: < 0.01, = 0.83) muscles. Similarly, participants performed more repetitions (push-ups: < 0.01; = 0.94; seated shoulder press: = 0.03, = 0.23), with higher movement velocity (all ≤ 0.04, all ≥ 0.47), and lower perceived exertion in the first repetition (push-ups: < 0.01, = 0.61; seated shoulder press: = 0.05; = 0.76) wearing the elastomeric garment compared to placebo. There were no between-garment differences in most cardiovascular variables (all ≥ 0.10). Higher diastolic blood pressure was only found after the seated shoulder press wearing the elastomeric garment compared to the placebo ( = 0.04; = 0.49). Finally, significantly lower blood lactate levels were achieved in the push-ups performed wearing the elastomeric garment ( < 0.01; = 0.91), but no significant differences were observed in the seated shoulder press ( = 0.08). Overall, the findings of this study suggest that elastomeric technology integrated into a sports garment provides an ergogenic effect on mechanical, physiological, and psychological variables during the execution of pushing upper-limb resistance exercises.
本研究旨在比较穿着运动弹性服装或安慰剂服装进行上身推类运动时的力学反应（提升速度和最大重复次数）、生理反应（肌肉激活、乳酸、心率和血压）以及心理反应（主观用力感觉评分）。19名身体活跃的年轻成年人随机完成了两个仅在使用的运动服装（弹性技术服装或安慰剂服装）上有所不同的训练课程。在每个课程中，受试者进行一组坐姿肩推和另一组俯卧撑，直至肌肉疲劳。在每组运动结束后立即测量因变量。与安慰剂服装相比，弹性服装能使参与者在胸大肌（俯卧撑： = 0.04， = 0.49；坐姿肩推： < 0.01， = 0.64）、肱三头肌（俯卧撑， < 0.01， = 0.77；坐姿肩推： < 0.01， = 0.65）和三角肌前束（俯卧撑： < 0.01， = 0.72；坐姿肩推： < 0.01， = 0.83）肌肉中获得更大的肌肉激活。同样，与安慰剂相比，穿着弹性服装时，参与者能完成更多的重复次数（俯卧撑： < 0.01； = 0.94；坐姿肩推： = 0.
