Attentional processes during submaximal exercises

Abstract

Blood levels of lactate and glucose were measured in 15 healthy male athletes with the purpose of evaluating possible correlation between their blood values and intensity and selectivity of attention, after a 30-min steady-state test performed at 60 and 80% of maximal oxygen consumption (VO_2max). On the basis of the results, we conclude that, during aerobic exercise, a worsening of attentional capabilities does not occur unless there is an increase of blood lactate above 4 mmol/l.
