摘要

摘要目的本研究旨在研究在玩家数量平衡和不平衡的情况下,使用不同相对游戏区域的小游戏中的生理、机械和感知负荷。方法收集12名优秀青年男子足球运动员的数据,包括使用商用GPS的心率和标准时间运动输出。结果随着音高大小的增加,数据显示出更高的心血管、身体和感知需求(例如,在中等音高格式和小音高格式中,平均HR分别为88.7和86.7%,高强度加速度分别为8和2。最大音高格式导致高强度距离的积累更大(47±30m),与最小投球相比,更高的峰值速度(25.2±1.6 km/h−1)和更高的距离和加速度频率(35±9 m和8±3)(均p<0.01)。结论这些数据表明,球队管理可以规定不同的比赛形式,包括数字失衡,以针对特定球员的条件刺激(例如,针对没有持续接触比赛的球员进行更高的训练负荷)。

The influence of relative playing area and player numerical imbalance on physical and perceptual demands in soccer small-sided game formats
ABSTRACT Purpose This study aimed to examine physiological, mechanical and perceptual loading in small-sided games using different relative playing areas with balanced and unbalanced player numbers. Methods Data were collected in twelve elite youth male soccer players and included heart rate and standard time-motion outputs using commercial GPS. Results The data demonstrated higher cardiovascular, physical and perceptual demands with increasing pitch size (e.g. average HR was 88.7 vs. 86.7% HRmax with 8 vs. 2 high-intensity acceleration in medium vs. small pitch formats. The largest pitch format resulted in a greater accumulation of high-intensity distance (47 ± 30 m), higher peak velocity (25.2 ± 1.6 km.h−1) and a higher distance and frequency of accelerations (35 ± 9 m and 8 ± 3) compared with the smallest pitch (all p < 0.01). In unbalanced games, there was significantly greater average heart rate in the overloaded team (84.4 ± 4.9 vs. 80.4 ± 4.8% HRmax in 4 v. 6). Conclusion These data suggest that different game formats including numerical imbalance could be prescribed for squad management to target conditioning stimuli for specific players (e.g. to target a higher training load for players that do not get consistent match exposure).
