Internal training load monitoring across a period training in volleyball players

The aim of this study was to monitor and analyze the dynamics of internal training load using session rating of perceived exertion (session-RPE) method during a training period of volleyball. Twelve volleyball players (23.5 ± 3.4 y, 88.2 ± 11.4 kg, 190.4 ± 10.8 cm) were monitored during 22 training weeks divided into five mesocycles. The ANOVA revealed that the total week training load (TWTL), monotony, and strain were different among the mesocycles (p < 0.05). The higher values of TWTL were showed during mesocycles 2, 4, and 5. Monotony presented values below 1.4 ± 0.1 AU. The mean TWTL of the 22 weeks presented a mean of 1790.9 UA and a coefficient of variation of 16%. The lower and higher mean values of TWTL of the 22 weeks were 1324.3 and 2232.7 UA, respectively. Thus, the internal training load distribution presented moments with higher and lower magnitude between weeks, and increase from 1st to 2nd mesocycle with maintenance of this following others mesocycles.本研究旨在采用感知运动负荷会话评分法（session rating of perceived exertion, session-RPE），监测并分析排球训练周期内的内部训练负荷动态变化。招募12名排球运动员（年龄23.5±3.4岁，体重88.2±11.4kg，身高190.4±10.8cm），对其22周的训练周期进行监测，该训练周期被划分为5个中周期。方差分析（ANOVA）结果表明，总周训练负荷（total week training load, TWTL）、单调指数（monotony）与负荷应变（strain）在各中周期间存在显著统计学差异（p<0.05）。中周期2、4、5的总周训练负荷数值更高；单调指数均值低于1.4±0.1任意单位（AU）。22周训练周期的总周训练负荷均值为1790.9 UA，变异系数为16%；该周期内总周训练负荷的最低与最高周均值分别为1324.3 UA与2232.7 UA。综上，内部训练负荷在各周间呈现出负荷大小不一的分布特征，且负荷水平从第1个中周期升至第2个中周期，后续各中周期则维持该负荷水平。
