This study examined the effect of active and passive recovery on lactate concentration and subsequent performance of repeated work bouts in 18 male NCAA Division I ice hockey players. Using a repeated measures design, subjects performed a series of skating tests before and after a 15-minute recovery. The skating test consisted of skating a course for 7 shifts, which lasted 40 seconds per shift with 90 seconds rest between shifts. Active recovery (low-intensity cycling) and passive recovery (sitting) lasted for 15 minutes and were followed by an identical 7-shift skating test. Passive vs. active recovery showed no statistically significant differences for distance skated, heart rate, or lactate. There appeared to be a trend for greater skating distance in period 2 when active recovery was used, but the difference was not significant (p > 0.05). It was concluded that active recovery did not enhance lactate removal or subsequent performance of repeated work bouts in simulated hockey play.
