The purpose was to compare the blood lactate response and performance of varsity hockey players to recreational players, and to provide a shift by shift analysis of blood lactate accumulation in a simulated ice hockey task. Ten university, varsity players and ten recreational players performed a continuous aerobic treadmill test (VO2max), a 45 s Wingate test, and four trials of the Repeat Sprint Skate (RSS) test. Each RSS test consisted of four repetitions of a 91.4 m skate with repetitions initiated on 30 s intervals. To simulate game, competition, 5 min of recovery separated each RSS test. Results indicated: (1) performance of the varsity players was superior (p < 0.01) to that of the recreational players in the RSS test; (2) four shifts of the RSS test elicited similar peak blood lactate concentrations for the varsity and recreational groups; (3) change in blood lactate following 15 min of passive recovery was similar in the two groups, and (4) there was a significant relationship (&prop; = 0.05) between performance indices in the RSS test and corresponding variables measured in the 45 s Wingate test.
