External Loads Of Men’S And Women’S Varsity Ice Hockey Players During A Practice And Game

PURPOSE: The purpose of this study was to quantify and compare internal load, using training impulse (TRIMP) and sessional rating of perceived exertion (sRPE), of men and women varsity ice hockey players during a practice and game. METHODS: Data (mean ± SD) were collected for 26 male (22.1 ± 1.1 yr, 85.9 ± 5.4 kg, 181.3 ± 5.1 cm) and 24 female (19.8 ± 1.4 yr, 68.0 ± 6.9 kg, 168.1 ± 5.9 cm) varsity ice hockey players. On-ice internal load was reported TRIMP (Arbitrary Units, AU), measured using HR monitors worn on the upper arm, and sessional rating of perceived exertion (sRPE, AU), using the Borg 10 RPE scale with time on-ice during one practice and one home game of the regular season. RESULTS: During the 75 min practices, the mean HRmax values for males and females were 183 ± 8 and 177 ± 14 bpm, indicating a high intensity for both with no significant difference between sexes (p=0.124). During the games (15-min warm-up and 3 X 20-min periods), the mean HRmax values for males and females were 178 ± 24 and 190 ± 5 bpm, with the females significantly higher than the males (p=0.044). The TRIMP scores for the males were 109 ± 49 and 91 ± 57 AU for the game and practice and not significantly different (p=0.263) and the sRPE scores were significantly (p=0.044) higher during the game (457 ± 234) vs. practice (346 ± 222 AU). The TRIMP scores for the females were 79 ± 25 and 94 ± 56 AU for the practice and game and not significantly different (p=0.261) and the sRPE were also not significantly different (p=0.445) between the practice (348 ± 152 AU) and game (390 ± 225 AU). Males had a significantly greater TRIMP (p=0.012) and sRPE (p=0.029) compared to females during the practices but there were no significant differences in TRIMP (p=0.875) or sRPE (p=0.487) between males and females during the game. Overall, there was a significant positive correlation between TRIMP and sRPE (p=0.029) but when separated into males and females, there was a significant correlation for the males (p=0.032) but no significant correlation for the females (p=0.770). CONCLUSION: Preliminary data suggests no differences in internal loads between practices and games for females, but game loads exceeded training loads for males. Furthermore, training loads were higher for males compared to females, however game loads were similar. Supported by a grant from Mitacs and PepsiCo.
