Attentional processes during submaximal exercises

In 15 healthy male athletes, blood levels of lactate and glucose were measured with the purpose to evaluate possible correlation between their blood values and intensity and selectivity of attention, after a steady 30 min steady-state test performed at 60% and 80% of VO2max. On the basis of results, we conclude that, during an aerobic exercise, does not occur a worsening of attentional capabilities, unless there is an increase of blood lactate above 4 mmol/l.
