Abstract The purpose of the present study was to examine the reliability and sensitivity of three ecologically valid repeated high intensity exercise (RHIE) tests for professional rugby league and rugby union players. A further purpose was to investigate the relationship between RHIE performance and measures of speed (20m sprint) and high-intensity intermittent running ability (yo-yo intermittent recovery test). Thirty six rugby union and rugby league players were separated into three equal groups based on playing position: backs, rugby league (RL) forwards and rugby union (RU) forwards. Test-retest reliability was assessed by comparing total sprint time over nine sprints during two identical testing sessions. The intra-class correlation coefficients (ICC) for total sprint time were moderate to high (0.82, 0.97 and 0.94) and coefficient of variation (CV) low (4.2%, 1.4%, and 0.6%) for the backs, RL forwards and RU forwards tests, respectively. However, sprint performance decrement scores were poorer, with ICC and CV of 0.78, 0.86 and 0.88 and 49.5%, 48.2%, and 35.8% for the backs, RL forwards and RU forwards, respectively. Total sprint times for the backs, RL forwards, and RU forwards decreased over the three tests by 0.54 s, 0.53 s and 2.09 s respectively. Changes in RHIE total sprint time were moderately related to changes in 20 m sprint times (T1 to T2; r = 0.63, T2 to T3; r = 0.69 and T1 to T3; r = 0.63; all p < 0.05), but not yo-yo intermittent recovery test performances. The present study has shown that the designed rugby league and rugby union RHIE tests have moderate to high reliability and produce significant improvements over a training period when total sprint times are compared.
