The effects of differing recovery patterns following intermittent exercise on blood lactate and subsequent performance were examined. Fourteen male subjects completed three randomly assigned experimental protocols. Each protocol consisted of eight 45s-bouts of cycling on a Monark cycle ergometer at 120% of VO$ sb2$ max interposed with five minute recovery periods. Each protocol ended with a maximal performance task consisting of a 45s all-out cycling test. Recovery patterns included passive, cycling (45% of VO$ sb2$ max), and arm cranking (45% of VO$ sb2$ max). Results revealed similar blood lactate concentrations in the passive and arm cranking conditions but significantly lower (p $<$.05) levels in the cycling condition. Mean power outputs measured from the performance task were significantly higher (p $<$.05) in the cycling and arm cranking recovery conditions. The correlation between blood lactate levels and mean power output was low (r = $-$0.28), suggesting that other factors were influencing subsequent performance.
