The purpose of this study was to establish the validity, reliability and objectivity of an intermittent cycling test of anaerobic power and endurance for ice hockey players. The intermittent cycling test consisted of 6 repetitions, each 15s in duration with each repetition separated by a 15s recovery interval resulting in a total work time of 90s and a work to recovery ratio of 1:1. Four groups of subjects completed laboratory and on‐ice anaerobic tests. The groups consisted of 17 varsity hockey players, 11 varsity and junior varsity players, 14 junior varsity players, and 15 physical education students. All four groups completed the intermittent cycling test. The three hockey groups were assessed on a repeat sprint skate test. Physiological and metabolic data were also collected on group 2 to investigate the aerobic and anaerobic intensity of the test. The intermittent cycling test discriminated among the varsity, junior varsity, and non‐varsity players, thereby establishing construct validity. Peak power (watts/kg) correlated significantly (r=–.87) with on‐ice skating speed while mean power (watts/kg) correlated significantly (r=–.78) with the anaerobic endurance index of the repeat sprint skate test. Hence, criterion related validity was established. Intraclass correlation coefficients of. 93 and. 99 attested to the reliability and objectivity of the intermittent cycling test. The test taxed both the aerobic and anaerobic sytems. Peak VO2during the test was 97.8% of VO2maxwith a post‐exercise lactate concentration of 13.3 mmol/1. The drop‐off in power output between repetitions 1 and 6 was 28% for the varsity players, 35% for the junior varsity hockey players, and 43% for the physical education students. It was concluded mat the intermittent cycling test is a valid, reliable, and objective test of the anaerobic endurance of ice hockey players.
