The aim of this cohort study was two-fold: (i) to analyze within-group changes of final velocity in a 30-15 intermittent fitness test (V), final velocity in a Vameval test (V), 20-m sprint and countermovement jump (CMJ); (ii) to explore the relationships between V and Vvameval outcomes and their changes with internal and external loads. Twenty-two professional soccer players (mean ± SD; age 27.2 ± 3.4 years, height 174.2 ± 3.6 cm, body mass 69.1 ± 6.4 kg, and body fat 10.4 ± 4.1%, 3.1 ± 1.5 years in the club) participated in this study. External and internal loads were obtained using global positioning system, heart rate and rate of perceived effort (sRPE) after each training session. Players were assessed in CMJ, 20-m sprint, Vameval and 30-15 intermittent fitness test, before and after the observed period. Very large relationships were observed between V and Vameval for pre- ( = 0.76), post ( = 0.80) and pooled-data ( = 0.81). V showed less sensitivity (-22.4%, [-45.0 to 9.4]), ES -0.45 [-1.05 to 0.16]) than V. ∆V had unclear associations with all sRPE, but had moderate correlations with objective internal and external measures, while, ∆V varied between large and very large relationships with all sRPE, but had unclear associations with all other selected training loads. Objective internal and external loads may be used to track aerobic power related changes from V.
（i）分析30-15间歇体能测试中的最终速度（V）、瓦梅瓦尔测试中的最终速度（V）、20米短跑和反向纵跳（CMJ）的组内变化；（ii）探讨V和瓦梅瓦尔测试结果之间的关系及其随内部和外部负荷的变化。22名职业足球运动员（平均值±标准差；年龄27.2±3.4岁，身高174.2±3.6厘米，体重69.1±6.4千克，体脂10.4±4.1%，在俱乐部效力3.1±1.5年）参与了本研究。每次训练课后，使用全球定位系统、心率和主观用力程度（sRPE）来获取外部和内部负荷。在观察期前后，对运动员进行CMJ、20米短跑、瓦梅瓦尔测试和30-15间歇体能测试评估。观察到V和瓦梅瓦尔测试在训练前（r = 0.76）、训练后（r = 0.80）和汇总数据（r = 0.81）之间存在非常强的相关性。V的敏感性低于V（-22.4%，[-45.0至9.4]），效应量ES为-0.45 [-1.05至0.16]）。∆V与所有sRPE的关联不明确，但与客观的内部和外部测量指标有中度相关性，而∆V与所有sRPE的相关性在大到非常强之间变化，但与所有其他选定的训练负荷的关联不明确。客观的内部和外部负荷可用于追踪与V相关的有氧能力变化。
