	abstract = {This study examined the effects of elevating blood lactate concentration by arm exercise on subsequent performance during repeated 30 s sprints with the legs. Eight male students performed two 30 s cycle ergometer sprints separated by 6 min of recovery, on two occasions. On one occasion the subjects performed only the two 30 s cycle ergometer sprints ({\textquoteright}legs{\textquoteright}), while on the other occasion 5 min of heavy arm cranking preceded the two sprints ({\textquoteright}arms and legs{\textquoteright}). Blood lactate concentration was determined from capillary samples at rest, after a standardized warm-up and 3 and 5 min following each exercise bout. In the {\textquoteright}legs{\textquoteright} condition, the peak power output (PPO) and mean power output (MPO) in the second sprint were 92\% (P \&lt; 0.05) and 85\% (P \&lt; 0.01) of the values attained during the first sprint, respectively. Prior arm exercise, which increased blood lactate to 11.0 {\textpm} 0.6 mM, had no effect on PPO and MPO during the first cycle ergometer sprint (≃ 4\% drop, N.S.). However, in the second sprint after prior arm exercise, PPO was 10\% lower than the PPO attained during the corresponding sprint in the {\textquoteright}legs{\textquoteright} condition (sprint 2 {\textquoteright}arms and legs{\textquoteright} 963 {\textpm} 42 W, sprint 2 {\textquoteright}legs{\textquoteright} 1074 {\textpm} 60 W, P \&lt; 0.05), while MPO was better maintained (sprint 2 {\textquoteright}arms and legs{\textquoteright} 517 {\textpm} 17 W, sprint 2 {\textquoteright}legs{\textquoteright} 549 {\textpm} 24 W, N.S.). The rate of blood lactate accumulation after both cycle ergometer sprints was considerably decreased (by ≃ 50\%) when blood lactate levels were pre-elevated by arm crank exercise. It is suggested that the elevation of blood lactate levels by prior arm exercise can cause a significant drop in PPO of the second sprint by decreasing muscle buffering capacity and lactate/H+ efflux from the muscle. The less pronounced drop in MPO during the second sprint in the {\textquoteright}arms and legs{\textquoteright} condition was assumed to be due to an increased aerobic contribution to energy supply.},
