Abstract

PURPOSE

The aim of this study was to analyze the within-week differences in external training intensity in different microcycles considering different playing positions in women elite volleyball players.

METHODS

The training and match data were collected during the 2020-2021 season, which included 10 friendly matches, 41 league matches and 11 champions league matches. The players' position, training/match duration, training/match load, local positioning system (LPS) total distance, LPS jumps, accelerations, decelerations, high metabolic load distance (HMLD), acute and chronic (AC) mean and AC ratio calculated with the rolling average (RA) method and the exponentially weighted moving average (EWMA) method, monotony and strain values were analyzed.

RESULTS

All the variables except strain, Acc/Dec ratio and acute mean (RA) showed significant differences among distance to match days. Regarding the players' positions, the only difference was found in the AC ratio (EWMA); in all microcycles, the middle blocker player showed workload values when compared with the left hitter, setter and libero.

CONCLUSION

Overall, the analysis revealed that the intensity of all performance indicators, except for strain, acc/dec and acute mean load (RA), showed significant differences among distance to match day with moderate to large effect sizes. When comparing players' positions, the middle blocker accumulated the lowest loads. There were no significant differences among other positions.

摘要

目的

本研究旨在分析不同微周期内,精英女排运动员不同场上位置的外部训练强度在一周内的差异。

方法

收集了2020 - 2021赛季的训练和比赛数据,包括10场友谊赛、41场联赛和11场欧冠比赛。分析了运动员的位置、训练/比赛时长、训练/比赛负荷、局部定位系统(LPS)总距离、LPS跳跃次数、加速次数、减速次数、高代谢负荷距离(HMLD),以及用滚动平均值(RA)法和指数加权移动平均值(EWMA)法计算的急性和慢性(AC)平均值及AC比值、单调值和应变值。

结果

除应变、加速/减速比值和急性平均值(RA)外,所有变量在距比赛日的天数上均存在显著差异。关于运动员的位置,仅在AC比值(EWMA)上发现差异;在所有微周期中,与左攻手、二传手和自由人相比,中间拦网球员的工作量值较高。

结论

总体而言,分析表明,除应变、加速/减速和急性平均负荷(RA)外,所有表现指标的强度在距比赛日的天数上均存在显著差异,效应大小为中等至较大。比较运动员位置时,中间拦网球员的负荷最低。其他位置之间无显著差异。
