Previous studies examining methods of monitoring the training and match load in soccer players have simply compared those methods to each other, not to changes in fitness. Training and match load measures from nine professional youth soccer players were collected for a period of six weeks. A lactate threshold test was conducted before and after this period. Mean weekly training and match load as determined by session-RPE, Banister's TRIMP, Team TRIMP and individualised TRIMP (iTRIMP) were correlated with each other, percentage changes in the velocity at 2 mmol · L(-1) (vLT) and 4 mmol · L(-1) (vOBLA) blood lactate concentration, and heart rate at 2 mmol · L(-1) (LT(HR)) and 4 mmol · L(-1) (OBLA(HR)). There were no significant changes in fitness across the six weeks: vLT (p = 0.54), vOBLA (p = 0.16), LT(HR) (p = 0.51) and OBLA(HR) (p = 0.63). Banister's TRIMP was significantly correlated with session-RPE (r = 0.75; p = 0.02) and Team TRIMP (r = 0.92; p < 0.001). The percentage change in vLT was significantly correlated to mean weekly iTRIMP (r = 0.67; p = 0.04). The results suggest that an individualised measure of internal load (iTRIMP) related better than other methods to changes in vLT in professional youth soccer players.
先前的研究检查了监测足球运动员训练和比赛负荷的方法，只是将这些方法相互比较，而不是与体能变化进行比较。在六周的时间里，收集了九名职业青年足球运动员的训练和比赛负荷测量数据。在这段时间前后进行了一次乳酸阈测试。通过会话 RPE、巴尼斯特 TRIMP、团队 TRIMP 和个体化 TRIMP（iTRIMP）确定的平均每周训练和比赛负荷与彼此相关，速度在 2 mmol·L(-1)（vLT）和 4 mmol·L(-1)（vOBLA）血乳酸浓度的百分比变化，以及 2 mmol·L(-1)（LT(HR)）和 4 mmol·L(-1)（OBLA(HR)）的心率。在六周内，体能没有明显变化：vLT（p = 0.54），vOBLA（p = 0.16），LT(HR)（p = 0.51）和 OBLA(HR)（p = 0.63）。巴尼斯特 TRIMP 与会话 RPE（r = 0.75；p = 0.02）和团队 TRIMP（r = 0.92；p < 0.001）显著相关。vLT 的百分比变化与平均每周 iTRIMP 显著相关（r = 0.67；p = 0.04）。结果表明，与其他方法相比，个体内部负荷（iTRIMP）的测量方法与专业青年足球运动员 vLT 的变化更好相关。
