摘要

疲劳引起跑步形式的改变,导致运动效率降低。减少疲劳量及其对形体的后续影响对于提高跑步表现是有价值的。目前还不清楚压缩服对肌肉组织有什么影响;然而,有人声称它可以减轻疲劳。这项研究的目的是确定当跑到精疲力竭时,压缩紧身衣和跑步短裤哪个更有利于提高表现。11名跑步者穿着紧身衣和跑步短裤,在跑步机上以目前5公里的比赛速度跑步,直到自愿精疲力竭,同时记录他们的生物力学、心率和感知运动的速度。疲劳效应表现为初始接触时膝关节伸角减小(p = 0.03),踝关节背屈角减小(p = 0.04),载荷率增大(p = 0.02),垂直冲击峰值增大(p = 0.05)。条件效应包括更短的步幅长度(p = 0.01),更快的步幅速率(p = 0.01)和压缩紧身衣减少髋关节活动范围(p = 0.02)。两组患者的疲劳时间差异无统计学意义(p = 0.88)。因此,到疲劳的时间长度不受条件的影响,然而,穿着紧身衣跑步时改变的力学可以减少潜在的伤害。

Biomechanical adjustments during an exhaustive treadmill run: comparison of compression tights and running shorts.

Fatigue induces changes to running form resulting in movements that are less efficient. Reducing the amount of fatigue and its subsequent effect on form is valuable for improving running performance. It is unknown what effects compressive clothing has on musculature; however, there have been claims that it may reduce fatigue. The aim of this study was to determine whether compressive tights or running shorts are more beneficial for improving performance when running to exhaustion. Eleven runners ran at their current five-kilometre race pace on a treadmill to voluntary exhaustion in a repeated measures design wearing both compression tights and running shorts while their biomechanics, heart rate and rate of perceived exertion were recorded. Fatigue effects showed a less extended knee angle (p = 0.03) and a smaller ankle dorsiflexion angle (p = 0.04) at initial contact, and increased loading rate (p = 0.02) and vertical impact peak (p = 0.05). Condition effects included a shorter stride length (p = 0.01), faster stride rate (p = 0.01), and decreased hip range of motion (p = 0.02) with compression tights. There was no significant difference in time to exhaustion between conditions (p = 0.88). Thus, the length of time to fatigue was unaffected by condition, however, the altered mechanics when running in compression tights may reduce potential injury.

期刊介绍: Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
