Riboli, A, Esposito, F, and Coratella, G. Small-sided games in elite football: practical solutions to replicate the 4-min match-derived maximal intensities. J Strength Cond Res 37(2): 366-374, 2023-The purpose of the study was to determine the area per player (ApP, m 2 ·player -1 ) to replicate the maximal 4-min match-play period (4-min Peak ) using small-sided or large-sided games (SSGs) lasting the same duration in elite football players. Twenty players (age: 26 ± 5 years) competing in European championship and international UEFA competitions were monitored during SSGs with (SSG with ) or without (SSG without ) goalkeepers, both lasting 4-min. A total of 1,724 and 561 individual observations for SSG with and SSG without across 99 and 34 different SSGs formats were undertaken. Whole (90-min avg ) and 4-min Peak match demands were calculated. Relative (m·min -1 ) total, high-speed (HSRD), very high-speed (VHSRD), sprint, and acceleration/deceleration distance were collected. For both SSG with and SSG without , ApP was small -to- very-largely correlated with TD, HSRD, VHSRD, and sprint, whereas an inverse trivial -to- small correlation with acceleration/deceleration was found. In SSG with , the ApP to replicate 4-min Peak was larger ( p < 0.001, effect size [ES]: 0.33-5.80) than that to mimic 90-min avg for total distance, HSRD, VHSRD, and sprint, whereas for acceleration/deceleration the ApP was lower ( p < 0.001, ES: -3.13 to 0.48) for 4-min Peak . In SSG without , the ApP to replicate 4-min Peak was larger ( p < 0.001, ES: 0.04-3.72) than that to mimic 90-min avg for HSRD, VHSRD, and sprint. Some positional differences ( p < 0.05, ES: 0.22-1.10) in ApP were found. The ApP to replicate 4-min Peak was higher for SSG with than SSG without ( p < 0.001, ES: 0.67-3.58). These findings may help practitioners to recreate the 4-min Peak to manage ApP during SSGs in elite football.
里博利、埃斯波西托和科拉泰拉。精英足球中的小场比赛:复制 4 分钟比赛衍生最大强度的实用解决方案。J 力量与调节研究 37(2):366-374,2023 年-本研究的目的是确定每位球员的面积(ApP,m 2 ·player -1 ),以使用在精英足球运动员中持续相同时间的小场或大场比赛(SSG)复制最大的 4 分钟比赛期(4 分钟高峰)。20 名参加欧洲锦标赛和国际 UEFA 比赛的球员在有(SSG with )和没有(SSG without )守门员的 SSG 中进行监测,持续 4 分钟。总共进行了 99 种不同的 SSG 格式和 34 种不同的 SSG 格式的 SSG with 和 SSG without ,分别进行了 1724 次和 561 次个体观察。计算了整个(90 分钟平均)和 4 分钟高峰比赛需求。收集了相对(m·min -1 )总距离、高速(HSRD)、超高速度(VHSRD)、冲刺和加速/减速距离。对于 SSG with 和 SSG without ,ApP 与 TD、HSRD、VHSRD 和冲刺呈小到非常大的相关性,而与加速/减速呈负相关,相关程度从微不足道到小。在 SSG with 中,复制 4 分钟高峰的 ApP 大于(p < 0.001,效应大小[ES]:0.33-5.80),而模拟总距离、HSRD、VHSRD 和冲刺的 90 分钟平均 ApP 则更大,而对于加速/减速,4 分钟高峰的 ApP 更小(p < 0.001,ES:-3.13 至 0.48)。在 SSG without 中,复制 4 分钟高峰的 ApP 大于(p < 0.001,ES:0.04-3.72),而模拟 90 分钟平均的 HSRD、VHSRD 和冲刺的 ApP 则更大。在 ApP 中发现了一些位置差异(p < 0.05,ES:0.22-1.10)。复制 4 分钟高峰的 ApP 在 SSG with 中高于 SSG without (p < 0.001,ES:0.67-3.58)。这些发现可能有助于教练在精英足球的 SSG 中复制 4 分钟高峰,以管理 ApP。
