The current case study aimed to quantify within-subjects correlations between training load and well-being in elite male beach soccer players. Data were obtained over three consecutive days during the preparation camp for the FIFA Beach Soccer World Cup Russia 2021. The session rating of perceived exertion (s-RPE) and external training load metrics using global positioning system (GPS) were recorded. Eleven players reported perceived well-being (sleep quality, fatigue, muscle soreness and stress) using a Likert scale (Hooper Index) before breakfast. Within-subjects correlation coefficients between workload and well-being were calculated. Workload metrics and perceived well-being indices were significantly lower on day three than on days one and two. The Hooper Index presented a positive correlation with s-RPE ( = 0.86 [0.67, 0.94], 95% confidence interval, CI), exposure time ( = 0.88 [0.71, 0.95]), total distance ( = 0.83 [0.60, 0.93]), high-speed distance ( = 0.77 [0.50, 0.91]), and number of sprints ( = 0.75 [0.47, 0.90]). Sleep quality presented a to positive correlation with s-RPE ( = 0.51 [0.11, 0.77]), exposure time ( = 0.50 [0.10, 0.76]), high-speed distance ( = 0.53 [0.15, 0.78]), number of sprints ( = 0.62 [0.28, 0.83]) and total distance ( = 0.41 [0.18, 0.78]). Fatigue presented a to positive correlation with s-RPE ( = 0.85 [0.66, 0.94]), exposure time ( = 0.90 [0.78, 0.96]), total distance ( = 0.86 [0.68, 0.94]), high-speed distance ( = 0.65 [0.31, 0.84]) and number of sprints ( = 0.56 [0.18, 0.79]). Muscle soreness presented a to positive correlation with s-RPE ( = 0.79 [0.56, 0.91]), exposure time ( = 0.83 [0.62, 0.93]), total distance ( = 0.81 [0.59, 0.92]), high-speed distance ( = 0.75 [0.47, 0.89]) and number of sprints ( = 0.59 [0.22, 0.81]). Overall, workload presented a meaningful correlation with perceived well-being indices in elite male beach soccer players during a training camp. These findings suggest that workload metrics and perceived well-being indices can be implemented into the daily routine of an elite beach soccer team, which may assist coaches, sports scientists, and practitioners in better preparing players for beach soccer competitions.
本案例研究旨在量化精英男沙滩足球运动员训练负荷与健康之间的个体内相关性。数据是在俄罗斯 2021 年国际足球联合会沙滩足球世界杯备战期间连续三天获得的。记录了赛中感知用力（s-RPE）和使用全球定位系统（GPS）的外部训练负荷指标。11 名球员在早餐前使用李克特量表（胡珀指数）报告了感知健康状况（睡眠质量、疲劳、肌肉酸痛和压力）。计算了工作负荷与健康状况之间的个体内相关系数。工作负荷指标和感知健康指数在第三天明显低于第 1 天和第 2 天。Hooper 指数与 s-RPE（ = 0.86 [0.67, 0.94]，95%置信区间，CI）、暴露时间（ = 0.88 [0.71, 0.95]）、总距离（ = 0.83 [0.60, 0.93]）、高速距离（ = 0.77 [0.50, 0.91]）和冲刺次数（ = 0.75 [0.47, 0.90]）呈正相关。睡眠质量与 s-RPE（ = 0.51 [0.11, 0.77]）、暴露时间（ = 0.50 [0.10, 0.76]）、高速距离（ = 0.53 [0.15, 0.78]）、冲刺次数（ = 0.62 [0.28, 0.83]）和总距离（ = 0.41 [0.18, 0.78]）呈正相关。疲劳与 s-RPE（ = 0.85 [0.66, 0.94]）、暴露时间（ = 0.90 [0.78, 0.96]）、总距离（ = 0.86 [0.68, 0.94]）、高速距离（ = 0.65 [0.31, 0.84]）和冲刺次数（ = 0.56 [0.18, 0.79]）呈正相关。肌肉酸痛与 s-RPE（ = 0.79 [0.56, 0.91]）、暴露时间（ = 0.83 [0.62, 0.93]）、总距离（ = 0.81 [0.59, 0.92]）、高速距离（ = 0.75 [0.47, 0.89]）和冲刺次数（ = 0.59 [0.22, 0.81]）呈正相关。总体而言，在训练营期间，工作负荷与精英男沙滩足球运动员的感知健康状况呈显著相关性。这些发现表明，工作负荷指标和感知健康状况指数可以纳入精英沙滩足球队的日常训练中，这可能有助于教练、运动科学家和从业者更好地为沙滩足球比赛做准备。
