Abstract

Background: Several authors have studied the influence of exercise on the nervous system and cognitive functioning in untrained subjects and different exercises from anaerobic exercise intense exercise to exhaustion at submaximal endurance exercise using the Flicker Fusion Threshold (UFF). Although the effect on the central nervous system (CNS) of maximum aerobic stimuli is not well studied. Objective: The purpose of this study is examine changes in Flicker Fusion thresholds before and after perform an incremental cycling test to exhaustion as a means to evaluate the central nervous system fatigue (SNC). Participants: 7 cyclists (62.6±4.11 kg, 172.8±7.94 cm, 14.7±0.8 years, 13.4±3.53 % grass, 21.0±1.83 kg/m2; VO2max [ml/ kg/min] 63.2±5.13, VO2max [l]: 4.1±0.5). Method: were tested in an incremental maximal test in cycle ergometer (starting at 50W with 50W increments every 5 minute until complete fatigue). The variables (UFF upward, downward and classic, the subjective test and sensory sensitivity) were measured pretest and postest. Each subject performed the test three times and obtaining an average value. Results: The results show an increase in the UFF, so fatigue does not occur in the CNS after a maximum incremental cycle ergometer test.
