The present study examined the prolonged effects of localized muscle fatigue on lactate production during exercise.

Subjects completed a max VO2 test and two testing sessions, which consisted of cycling for 20 minutes at 80%-85% max VO2, once with prior fatigue and once without. Two-way repeated measures ANOVA showed gross lactate production was 20% higher in the non-fatigue trial than in the fatigue trial (9.3 {dollar}\\pm{dollar}.03 vs. 7.6 {dollar}\\pm{dollar}.04, p =.02). Net lactate production was 34% higher in the non-fatigued trial than in the fatigue trial (7.8 {dollar}\\pm{dollar}.4 vs. 5.2 {dollar}\\pm{dollar}.4, p =.006).
