本研究的目的是检查穿着压缩相比，经典的弹性紧身裤和传统的短裤（对照试验）的氧气消耗和感觉反应在次极量跑步运动的影响。在第一部分中，对6名经过训练的运动员在10、12、14和16 km跑时的有氧能量消耗进行了评估。h（-1）。在第二部分中，能源成本随着时间的推移而增加（即，慢成分表示为运动结束时和最后2分钟之间的VO 2值的差异）在6名训练过的跑步者中以恒定的跑步配速（相当于最大VO 2的80%）持续15分钟。所有的测试都是在200米的室内跑道上进行的，具有等效的热应力条件。在所有测试期间，使用便携式代谢系统（Cosmed K4 b（2），罗马，意大利）测定VO 2。在每次试验后，跑步者被要求对他们的感知努力（RPE）和对服装，出汗，舒适度和整体热感觉的感知进行评分。结果表明，在第一部分中，仅在12公里处的能源成本显着降低。h（-1）通过穿着压缩和弹性紧身衣相比，传统的短裤。在第二部分，穿着压缩紧身衣显着降低VO 2慢成分26和36%相比，弹性紧身衣和传统的短裤，分别。有出汗和舒适的感觉，RPE，并为整个热感觉之间的服装条件的第一部分和第二部分没有差异。在跑步运动期间穿着压缩紧身衣可以增强整体循环并减少肌肉振荡，以促进在给定的延长的次最大速度下的较低能量消耗。
This study aimed to examine the effects of wearing compression compared to classic elastic tights and conventional shorts (control trial) on oxygen cost and sensation responses during submaximal running exercise. In part I, aerobic energy cost was evaluated in six trained runners at 10, 12,14, and 16 km (.) h(-1). In part II, the increase in energy cost over time (i.e., slow component expressed as difference in VO2 values between min 2 and end-exercise) was determined in six trained runners at a constant running pace corresponding to 80% of maximal VO2 for 15 min duration. All tests were performed on a 200-m indoor track with equivalent thermal stress conditions. VO2 was determined with a portable metabolic system (Cosmed K4b(2), Rome, Italy) during all testing sessions. Runners were asked their ratings of percieved exertion (RPE) and perceptions for clothing, sweating, comfort, and whole thermal sensations following each trial. Results showed in part I a significant lower energy cost only at 12 km (.) h(-1) by wearing compression and elastic tights compared to conventional shorts. During part II, wearing compression tights decreased significantly VO2 slow component by 26 and 36% compared to elastic tights and conventional shorts, respectively. There were no differences in sweating and comfort sensations, RPE, and for whole thermal sensation between clothing conditions in parts I and II. Wearing compression tights during running exercise may enhance overall circulation and decrease muscle oscillation to promote a lower energy expenditure at a given prolonged submaximal speed.
