The aim of this study was to investigate the physiological demands and technical-tactical performances of field players in Italian elite beach soccer team.
Three official matches of the Italian First Division beach soccer tournament were analyzed to evaluate the heart rate (HR) and time-motion analysis considering: standing, walking, jogging, running and sprinting, and technical-tactical aspects. Repeated-measures ANOVAs were used to determine the effects of time on the physiological measures and time motion analysis.
The mean heart rate (HR) was 161±20 b·min-1 corresponding to an overall mean of 84.3±10.5% of maximum heart rate (HRmax). Beach soccer players spent 52.5% of the time exercising at HR>85% of their HRmax. The time motion analysis results showed that for 50% of the match the players performed very low intensity activities. The notational analysis showed that during the 52.8% of the offensive actions 2 players were involved and the 42.6% of the offensive actions was performed by one pass.
These findings demonstrate that the beach soccer is an intermittent high intensity sport with a significant involvement of anaerobic metabolism. The results of time motion analysis and notational analysis underscored that the sand does not support the movements of players overall high intensity running. Team work is difficult to implement due to irregular rebounds and it does not consent precise passes. Furthermore this study suggests that it is important to include an intermittent training with high intensity and short recovery to improve the athlete's performance.
本研究旨在调查意大利精英沙滩足球队中场上球员的生理需求以及技术战术表现。
分析了意大利甲级沙滩足球锦标赛的三场正式比赛,以评估心率(HR)以及时间动作分析,其中考虑了:站立、行走、慢跑、跑步和冲刺,以及技术战术方面。采用重复测量方差分析来确定时间对生理指标和时间动作分析的影响。
平均心率(HR)为161±20次·分钟-1,相当于最大心率(HRmax)总体平均值的84.3±10.5%。沙滩足球运动员在心率>其HRmax的85%时花费52.5%的时间进行运动。时间动作分析结果表明,在比赛的50%时间里,球员进行的是极低强度活动。记录分析表明,在52.8%的进攻动作中有2名球员参与,42.6%的进攻动作是通过一次传球完成的。
这些发现表明,沙滩足球是一项间歇性高强度运动,无氧代谢参与度高。时间动作分析和记录分析的结果强调,沙子不利于球员进行整体高强度奔跑。由于反弹不规则,团队协作难以实施,也不利于精准传球。此外,本研究表明,进行高强度且恢复时间短的间歇性训练对于提高运动员的表现很重要。
