Abstract

BACKGROUND

The most demanding scenarios and physical demands of elite basketball 5-on-5 scrimmages are unknown to trainers, although recent advances in microtechnology allows the gaps in this research to be filled. The purpose of this study was to describe and compare the physical demands, through the most demanding scenarios and traditional average measures, of two different 5-on-5 scrimmage situations executed during training sessions in elite male basketball players.

METHODS

Physical demand measures (i.e., total distance covered, high-speed running distance, number of high-intensity accelerations actions, number of high-intensity decelerations actions) were collected from 12 players from the Spanish first Division using a Local Positioning System. Measures were compared via a Bayesian inference analysis, considering playing in half-court (HALF) and half-court and transition (HTRAN) conditions for the 5-on-5 scrimmage.

RESULTS

This study showed that, irrespective of the approach used to quantify the physical demands (traditional [average measures per minute] and novel rolling average time epoch [most demanding scenarios]), during the HALF condition players covered less and performed a lower number of high-intensity accelerations and decelerations than in HTRAN (Bayesian factor >10 and standardized effect size >0.6). Furthermore, players' physical demands during 5-on-5 scrimmage situations, independently of the court size, were underestimated consistently by the traditional approach.

CONCLUSIONS

Quantifying players' physical demands through the rolling approach may provide a more accurate measure of the most intense periods of activity. Based on the physical demands described, HTRAN may be used to help train players to perform optimally during the most physically-stressful scenarios of match-play whereas HALF may be more suitable to be included in warm-ups, recovery sessions and sessions immediately before a match.

摘要

背景

尽管最近微技术的进步可以填补这方面研究的空白,但精英篮球 5 对 5 模拟比赛中最苛刻的场景和身体需求对教练来说仍是未知的。本研究的目的是描述和比较两种不同的 5 对 5 模拟比赛情况下精英男性篮球运动员在训练期间的身体需求,通过最苛刻的场景和传统平均指标来进行比较。

方法

使用局部定位系统从西班牙甲级联赛的 12 名球员身上收集身体需求指标(即总距离、高速跑动距离、高强度加速次数、高强度减速次数)。通过贝叶斯推理分析比较措施,考虑在半场(HALF)和半场和过渡(HTRAN)条件下进行 5 对 5 模拟比赛。

结果

本研究表明,无论使用何种方法来量化身体需求(传统的[每分钟平均指标]和新的滚动平均时间区间[最苛刻的场景]),在 HALF 条件下,球员的覆盖范围较小,高强度加速和减速次数也少于 HTRAN(贝叶斯因子>10,标准化效应大小>0.6)。此外,球员在 5 对 5 模拟比赛情况下的身体需求,无论球场大小如何,传统方法都一直低估了球员的身体需求。

结论

通过滚动方法量化球员的身体需求可以更准确地衡量最激烈的活动时期。根据所描述的身体需求,HTRAN 可用于帮助训练球员在比赛中最具身体压力的场景中表现最佳,而 HALF 可能更适合在热身、恢复和比赛前的训练中使用。
