The purpose of this study was to determine if the HRindex Method (VO2max = [6 x HRindex - 5] x 3.5, where HRindex = HRmax/HRrest) was accurate for tracking changes in VO2max following 8-weeks of endurance training among collegiate female soccer players. Predicted VO2max via the HRindex Method and observed VO2max from a maximal exercise test on a treadmill were determined for a group of female soccer athletes (n = 15) before and following an 8-week endurance training protocol. The predicted (pVO2max) and observed (aVO2max) values were compared at baseline and within 1-week post-training. Change values (i.e., the difference between pre to post) for each variable were also determined and compared. There was a significant difference between aVO2max before (43.2 ± 2.8 ml·kg·min(-1)) and following (46.2 ± 2.1 ml·kg·min(-1)) the 8-week training program (p < 0.05). However, pVO2max did not significantly change following training (pre = 43.4 ± 4.6 ml·kg·min(-1), post = 42.9 ± 4.1 ml·kg·min(-1), p = 0.53). Furthermore, the correlation between the change in aVO2max and the change in pVO2max was trivial and non-significant (r = 0.30, p = 0.28). The HRindex Method does not appear to be suitable for predicting changes in VO2max following 8-weeks of endurance training in female collegiate soccer players.
本研究的目的是确定HR指数法（最大摄氧量= [6×HR指数 - 5]×3.5，其中HR指数=最大心率/静息心率）对于追踪大学女子足球运动员进行8周耐力训练后最大摄氧量的变化是否准确。在一组女子足球运动员（n = 15）进行8周耐力训练方案之前和之后，通过HR指数法预测的最大摄氧量以及在跑步机上进行的最大运动测试中观察到的最大摄氧量。在基线和训练后1周内比较预测值（pVO2max）和观察值（aVO2max）。还确定并比较了每个变量的变化值（即训练前与训练后的差值）。8周训练计划之前（43.2±2.8 ml·kg·min(-1)）和之后（46.2±2.1 ml·kg·min(-1)）的aVO2max之间存在显著差异（p < 0.05）。然而，训练后pVO2max没有显著变化（训练前= 43.4±4.6 ml·kg·min(-1)，训练后= 42.9±4.1 ml·kg·min(-1)，p = 0.53）。此外，aVO2max的变化与pVO2max的变化之间的相关性很小且无统计学意义（r = 0.30，p = 0.28）。HR指数法似乎不适用于预测大学女子足球运动员进行8周耐力训练后最大摄氧量的变化。
