摘要

摘要本研究的目的是比较临界速度(CV)测试中估计的跑步速度与10公里比赛中的实际跑步速度。这是一项横断面研究,有34名跑步者,20名男性和14名女性(42,4±11,0)。参与者参加了两天的测试和一天的正式10公里比赛。参观期间进行了以下试验:1)400米跑道试验和2)2000米跑道试验。他们被随机挑选,并被安排在官方田径跑道上,其间至少休息48小时。参与研究的运动员被要求适当地恢复、进食和补水。CV计算为距离与比赛时间的线性关系,对应线性回归线的斜率。两项试验都是在类似的气候条件下进行的。我们发现通过CV测试估计的速度与10公里比赛的实际跑步速度之间有很好的一致性。虽然CV测试估计的速度与实际10公里比赛的速度存在差异,但变化增量很低。因此,这些数据表明CV测试似乎是估计10公里比赛速度的好工具。在400米和2000米两个固定距离的场地上测定的CV可以有效地估计10公里比赛的跑步速度。

Critical velocity estimates running velocity in a 10-km running race in recreational runners
Abstract The aim of this study was to compare the estimated running velocity in a critical velocity (CV) test with the real running velocity in a 10-km race. This is a cross-sectional study with a convenience sample of 34 runners, 20 males and 14 females (42,4 ± 11,0). The participants attended two days of testing and one day to participate in an official 10-km race. During the visits, the following tests were performed: i) 400-meter running track test and ii) 2000 meter running track test. They were randomly selected and held in official athletics track with at least 48 hours rest between them. The athletes were instructed to participate in the study properly recovered, fed and hydrated. The CV was calculated as the linear relation between distance and race time, corresponding to the slope of the linear regression line. Both tests occurred in similar climatic situations. We found good agreement between the velocities estimated through the CV test and the real running velocity of a 10-km race. Although there was a difference in velocities estimated by the CV test and the real 10-km race, the variation delta was low. Thus, these data indicate that the CV test seems to be a good tool for estimating the velocity of a 10-km race. The CV determined in the field with two fixed distances 400 and 2000 meter was valid to estimate the running velocity of a 10-km race.

期刊介绍: The Brazilian Journal of Kinanthropometry and Human Performance is a journal of Physical Education, Kinesiology, Sport and related areas, whose focus is human movement, being reviewed by an international panel of peers, with emphasis on the measurement of the man in its morphological and functional aspects, as well as conditioning factors of physical performance. Given the multidisciplinary nature of the journal, these areas of study are approached in several contexts, with interactions with social, behavioral, health and environmental aspects. The journal publishes original articles as well as relevant Review/Update articles and Points of View.
