The aim of this study was 2-fold: (1) to examine the relationships between psychophysiological responses and locomotor demands with variations in technical performance during 2v2 and 4v4 conditioned games and (2) to compare psychophysiological and locomotor responses among players exhibiting higher and lower technical performance levels during the conditioned games.
Twenty-four male youth soccer players (16.3 ± 0.8 y old) participating at the trained/developmental level underwent monitoring for psychophysiological responses (including heart rate, rating of perceived exertion, and visual analog scale), locomotor demands (such as distance covered), and technical performance variables (including successful and unsuccessful passes and shots, as well as lost balls) across 2v2 and 4v4 formats. These formats were applied 4 times within a single session and were replicated twice over 2 weeks.
Large correlations between the number of lost balls per minute and mean heart rate were found in both the 2v2 and 4v4 games (r = .586 and r = .665, respectively). Successful shots were inversely and largely correlated with mean heart rate (r = -.518) in 4v4 games. The number of interceptions per minute was inversely and significantly correlated with the visual analog scale in 2v2 and 4v4 games (r = -.455 and r = -.710, respectively). The frequency of lost balls was significantly higher among players who attained a higher mean heart rate (2v2: +42.9%, P = .031, d = -0.965; 4v4: +57.1%, P < .001, d = -2.072).
Coaches should be aware that highly psychophysiologically demanding scenarios may significantly impair technical performance. Therefore, prioritizing technical performance by deliberately adjusting the intensity should be considered.
本研究旨在:(1)探究 2 对 2 和 4 对 4 条件比赛中技术表现变化时,运动员的心理生理反应和跑动需求之间的关系;(2)比较条件比赛中技术表现较高和较低的运动员的心理生理和跑动反应。
24 名男性青少年足球运动员(16.3±0.8 岁),参加训练/发展水平,在 2 对 2 和 4 对 4 格式下,进行心理生理反应(包括心率、感知运动评分和视觉模拟量表)、跑动需求(如跑动距离)和技术表现变量(包括成功和不成功传球和射门,以及丢球)的监测。这些格式在单个会议中进行了 4 次,在 2 周内重复了 2 次。
在 2 对 2 和 4 对 4 比赛中,每分钟丢球数与平均心率之间存在较大相关性(r =.586 和 r =.665)。4 对 4 比赛中,成功射门与平均心率呈负相关(r = -.518)。每分钟拦截次数与 2 对 2 和 4 对 4 比赛中的视觉模拟量表呈负相关(r = -.455 和 r = -.710)。在达到较高平均心率的运动员中,丢球频率明显较高(2 对 2:+42.9%,P =.031,d = -0.965;4 对 4:+57.1%,P <.001,d = -2.072)。
教练应意识到,高度心理生理需求的情况下可能会严重影响技术表现。因此,应优先考虑技术表现,通过有目的地调整强度来实现。
