摘要

本研究旨在探讨年轻成年运动员在不同制动力下10-s最大循环努力所获得的性能参数的可重复性。48例男性运动员,年龄18.9 ~ 29.9岁(175.5±6.9 cm, 76.2±10.1 kg)。运动方案在一个随机制动力(体重的4%至11%)的自行车测力仪中进行。在一周内通过重复测试检查个体内变异。计算描述性统计数据,并使用配对t检验检验会话之间的差异。计算了重复测量的相关系数、技术测量误差(TEM)、变异系数和ICC。使用Bland-Altman程序检查试验之间的一致性。当采样率为50 Hz时,峰值功率的平均值相对稳定,在1068瓦至1082瓦之间(t(47) = 1.149, p = 0.256, ES-r = 0.165)或对应于采样率为1 Hz时(t(47) = 0.742, p = 0.462, ES-r = 0.107)。重复测量之间的相关性很高(+0.907,95% CI: +0.839 ~ +0.947), TEM约为59.3瓦特(%CV = 5.52%;ICC = 0.951, 95% CI: 0.912 ~ 0.972)。目前的研究表明,男性成年运动员的峰值功率的再现性往往是可以接受的,在个人误差似乎与制动力无关。

Reproducibility of peak power output during a 10-s cycling maximal effort using different sampling rates.

The study was aimed to investigate the reproducibility of performance parameters obtained from 10-s maximal cycling effort against different braking forces in young adult athletes. The sample (n = 48) included male athletes aged 18.9-29.9 years (175.5 ± 6.9 cm, 76.2 ± 10.1 kg). The exercise protocol was performed in a cycle-ergometer against a random braking force (4% to 11% of body mass). Intra-individual variation was examined from repeated tests within one week. Descriptive statistics were computed and differences between sessions were tested using paired t-test. The coefficient of correlation between repeated measures, technical error of measurement (TEM), coefficient of variation and ICC were calculated. Agreement between trials was examined using the Bland-Altman procedure. Mean values of peak power were relatively stable when obtained from sampling rates of 50 Hz and ranged between 1068 watt and 1082 watt (t(47) = 1.149, p = 0.256, ES-r = 0.165) or while corresponding to a sampling rate of 1 Hz (t(47) = 0.742, p = 0.462, ES-r = 0.107). Correlations between repeated measures were high (+0.907, 95% CI: +0.839 to +0.947) and TEM about 59.3 watt (%CV = 5.52%; ICC = 0.951, 95% CI: 0.912 to 0.972). The present study suggests that reproducibility of peak power in male adult athletes tended to be acceptable and within individual error appeared unrelated to braking force.
