ABSTRACT
Objectives: The aim of this research was to establish cognitive changes in relation to blood lactate levels obtained during slow performance of a regimen of exercise sessions.
Methods: A total of 15 male professional bodybuilders participated in the study; CrossFit® professionals performed the Workout 15.5, Week 5 Open 2015 consisting of 27-21-15-9 repetitions for time of Row (calories) and Thrusters, with 1-min recovery. Blood lactate, blood glucose, reaction time (RT), execution time of a dual cognitive task, number of errors, and number of omissions were measured at rest, at conclusion of the session, and after recovery for 15 min.
Results: The bodybuilders had slightly elevated basal lactate levels than in untrained individuals. The bodybuilders showed significantly increased lactacidemia and decreased RT after completing the training session. Need to define what onset of blood lactate accumulation (OBLA) means.
Conclusion: We conclude that bodybuilding fitness regimens lead to an increase in basal lactate levels to 3.16 mmol/L and that acute training sessions can improve attentional performance in relation to lactacidemia, suggesting pro-cognitive effects of a workout.
