Tometz, MJ, Jevas, SA, Esposito, PM, and Annaccone, AR. Validation of internal and external load metrics in NCAA D1 women's beach volleyball. J Strength Cond Res 36(8): 2223-2229, 2022-The purpose of this study was to determine the validity of internal and external load metrics in NCAA D1 women's beach volleyball. Subjects included 13 NCAA D1 women's beach volleyball players (age: 20.3 ± 1.4 years). A total of 578 data points were analyzed from 51 team training sessions, including practice, games, and sport-specific conditioning during the pre-season semester (15 weeks). Data points included Edward's training impulse (TRIMP) (228.0 ± 80.7 arbitrary units [AU]), session rating of perceived exertion (sRPE) Load (532.5 ± 232.8 [AU]), distance covered (DC) in meters (2,635.4 ± 884.3 [m]), and daily environmental condition variables {(temperature (76.5 ± 13.7 [°F]), relative humidity (72.5 ± 13.2 [%]), and wet-bulb globe temperature (52.9 ± 19.9 [°F])}. The subjects wore Polar Team Pro heart rate monitors with global positioning system during each session. Subjects completed an sRPE questionnaire after every session. Pearson product moment correlations yielded statistically significant relationships (p < 0.01) between TRIMP and sRPE Load (r = 0.81), TRIMP and DC (r = 0.78), and sRPE Load and DC (r = 0.82). A forward selection multiple regression yielded that sRPE Load could predict TRIMP with the equation: TRIMPTometz = 78.735 + (sRPE Load * 0.28) (p < 0.001). These findings support sRPE Load as a valid alternative to TRIMP when monitoring internal loads in NCAA D1 women's beach volleyball. Session rating of perceived exertion Load may be more practical and accessible for teams. Distance covered should be considered when periodizing and monitoring training loads because of its relationship with internal loads.
托梅茨、Jevas、埃斯波西托、安纳科内。美国大学生体育协会（NCAA）一级女子沙滩排球内部和外部负荷指标的验证。《力量与调节研究杂志》36(8)：2223-2229，2022-本研究的目的是确定美国大学生体育协会一级女子沙滩排球内部和外部负荷指标的有效性。研究对象包括 13 名美国大学生体育协会一级女子沙滩排球运动员（年龄：20.3±1.4 岁）。在整个赛季（15 周）的 preseason 期间，从 51 次团队训练中分析了 578 个数据点，包括练习、比赛和专项体能训练。数据点包括爱德华训练冲动（TRIMP）（228.0±80.7 个任意单位[AU]）、会话感知用力（sRPE）负荷（532.5±232.8[AU]）、以米为单位的距离（2635.4±884.3[m]）和每日环境条件变量{（温度（76.5±13.7[°F]）、相对湿度（72.5±13.2[%]）和湿球温度（52.9±19.9[°F]）}。在每次训练中，运动员都佩戴 Polar Team Pro 心率监测器和全球定位系统。每次训练后，运动员都会完成一份 sRPE 问卷。皮尔逊积矩相关产生了统计学上显著的关系（p<0.01），TRIMP 与 sRPE 负荷（r=0.81）、TRIMP 与 DC（r=0.78）和 sRPE 负荷与 DC（r=0.82）。向前选择多元回归表明，sRPE 负荷可以通过以下公式预测 TRIMP：TRIMPTometz=78.735+（sRPE 负荷*0.28）（p<0.001）。这些发现支持在监测美国大学生体育协会一级女子沙滩排球内部负荷时，sRPE 负荷是 TRIMP 的有效替代方法。sRPE 负荷可能更实用，更容易为团队所接受。考虑到其与内部负荷的关系，在进行训练负荷分期和监测时，应考虑距离。
