The aims of the study were to modify the training impulse (TRIMP) method of quantifying training load for use with intermittent team sports, and to examine the relationship between this modified TRIMP (TRIMP(MOD)) and changes in the physiological profile of team sport players during a competitive season. Eight male field hockey players, participating in the English Premier Division, took part in the study (mean+/-s: age 26+/-4 years, body mass 80.8+/-5.2 kg, stature 1.82+/-0.04 m). Participants performed three treadmill exercise tests at the start of the competitive season and mid-season: a submaximal test to establish the treadmill speed at a blood lactate concentration of 4 mmol . l(-1); a maximal incremental test to determine maximal oxygen uptake ([V]O(2max)) and peak running speed; and an all-out constant-load test to determine time to exhaustion. Heart rate was recorded during all training sessions and match-play, from which TRIMP(MOD) was calculated. Mean weekly TRIMP(MOD) was correlated with the change in [V]O(2max) and treadmill speed at a blood lactate concentration of 4 mmol x l(-1) from the start of to mid-season (P<0.05). The results suggest that TRIMP(MOD) is a means of quantifying training load in team sports and can be used to prescribe training for the maintenance or improvement of aerobic fitness during the competitive season.
本研究的目的是调整用于量化间歇团队运动训练负荷的训练冲动（TRIMP）方法，并研究这种调整后的TRIMP（TRIMP(MOD)）与团队运动运动员在竞争赛季生理状况变化之间的关系。八名参加英格兰超级联赛的男子曲棍球运动员参与了该研究（平均值±标准差：年龄26±4岁，体重80.8±5.2千克，身高1.82±0.04米）。参与者在竞争赛季开始时和赛季中期进行了三项跑步机运动测试：一项亚极量测试，以确定血乳酸浓度为4 mmol·l⁻¹时的跑步机速度；一项最大递增测试，以确定最大摄氧量（[V]O₂max）和最高跑步速度；以及一项全力恒定负荷测试，以确定疲劳时间。在所有训练课程和比赛期间记录心率，并据此计算TRIMP(MOD)。平均每周TRIMP(MOD)与从赛季开始到赛季中期血乳酸浓度为4 mmol·x·l⁻¹时[V]O₂max和跑步机速度的变化相关（P<0.05）。结果表明，TRIMP(MOD)是一种量化团队运动训练负荷的方法，可用于在竞争赛季规定训练，以维持或提高有氧适能。
