Cortical arousal and central nervous system fatigue after a mountain marathon

Ultraendurance research has focused on the study of physiological parameters and body composition.

Sumario:Ultraendurance research has focused on the study of physiological parameters and body composition. The study of the influence on cognitive function and central nervous system (CNS) using the Critical Flicker Fusion Threshold (CFFT) has not been measured in this event. The objective of this study was to analyzed changes in CFFT before and after a mountain marathon. We analysed 26 athletes (22 men and 4 women, 66.9 ± 10.0 kg, 171.4 ± 7.1 cm, 37.8 ± 9.9 years). Before and after the event the mountain marathon runners performed a CFFT test, and for every test each subject performed the CFFT test three times. In addition, blood lactate concentration was analysed before and after the race as well as measuring heart rate during the race. The results found that the CFFT decreased after the event, with non-significance shown (p < 0.05). The mean heart rate was150.9 ± 7.9 bpm and final lactate concentration was 4.5 ± 1.2 mmol/l. The mountain marathon event was not therefore, found to affect the CNS, fatigue was caused by other peripheral causes.
