This study examined the effect of active and passive recovery on lactate concentration and subsequent performance of repeated work bouts in IS male college ice hockey players. Using a repeated measure 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 lasting 40 sec per shift with 90 sec rest between shifts. The recovery active (low intensity cycling) or passive (sitting) recovery lasted for 15 minutes followed by an identical seven shift skating test. Lactate was measured at rest, 3-5 min following the first skating test and 12-15 min into the recovery period. A 2 x 2 analysis of variance with repeated measures of distance and heart rate revealed significant differences between period 1 and 2 for both variables ( p=0.002 and p = 0.001 respectively). There was no interaction between periods and recovery for either distance or heart rate. Passive versus active recovery also showed no statistically significant difference for distance skated or heart rate. No significant difference was found in lactate between active or passive recovery. However, lactate at 3-5 min was greater than at 12-15 min (p<0.001). Pearson correlation coefficient showed no relationship for lactate changes during active recovery to skating distance (r = 0.11, p>0.05) or HR (r ~ 0.21, p>0.05) in the second period. No relationship was found among heart rate during period 2 for either active or passive 12 min lactate values. There appeared to be a trend for greater skating distance in period 2 when active recovery was used, but the difference was not significant. It was concluded that active recovery did not enhance lactate removal or subsequent performance of repeated work bouts.
