Abstract While the effect of lower body compression garments on performance and physiological responses are well documented, no studies have examined the effect of upper body compression garments (UBCG) on upper-body dominant exercise. This study examined the effects of wearing UBCG on performance and physiological responses during simulated flat-water kayaking. Five male (mean values±s: 21.8±2.8 years; 83.5±9.2 kg; 63.0±5.5 ml·kg?1·min?1) and two female (mean values±s: 25.0±4.2 years; 71.4±2.7 kg; 51.0±4.8 ml·kg-1·min-1) elite flat-water kayakers completed a six-step incremental test followed by a four-minute maximal performance test (4minPT) in both UBCG and control (no shirt or sports training bra) conditions in a randomized counter-balanced order. Heart rate and oxygen consumption (O2) as well as performance measures (power, distance covered, stroke rate) were recorded during the tests, and blood lactate was measured immediately after each incremental step and three minutes following the 4minPT. Near-infrared spectroscopy-derived measures of blood flow and oxygenation of the flexor carpi radialis were monitored continuously for all tests. No significant differences between the UBCG and control conditions were evident for any performance, cardiorespiratory or oxygenation measure across the incremental step test and 4minPT. It was concluded that wearing UBCG did not provide any significant physiological or performance benefits during simulated flat-water kayaking. 相似文献

针对基本权利的效力需要由法律的具体化才能实现的观点,分类讨论了基本权利效力的实现途径,概括出基本权利独立的规范价值。虽然不同性质的基本权利的实现途径是不一样的,但基本权利规范都有其独立的价值,主要表现在:基本权利有其独立存在的形态,不因为立法的具体化而失去效力;它的直接效力表现为赋予国家以一定的义务,包括消极的义务和积极的义务,以及对立法进行调控与制约的“高级法”效力;国家没有履行义务而使基本权利受到侵害时,可以提请宪法诉讼。 相似文献
