Introduction:
Several authors have studied the influence of exercise
on the nervous system and cognitive functioning in untrained subjects and different types of efforts using the
Flicker Fusion Threshold (FFT). However, the effect on
the central nervous system (CNS) of maximum aerobic
stimuli is not well studied. The purpose of this study was
to examine changes in FFT before and after perform an
incremental VO2max running test as a means to evaluate
the CNS fatigue.
Methods:
9 male trained triathletes (26±6.7 years; 173.3±5.9 cm;
66.4±5.9 kg; VO2max: 59.5±5.1 ml/kg/min) were tested in
an incremental treadmill maximal running test (starting at
10 km/h during 5 min and with 1km/h increments every 1
min until complete fatigue). Before and after the maximal
test the subject performed ascending and descending test,
3 times and average value was analysed. FFT ascendent
(FFTa) and descendent (FFTd), the subjective test (ST) and
sensory sensitivity (SS) was recorded by Lafayette Instrument Flicker Fusion Control Unit. The flicker frequency
increment (2Hz/sec) changed in 2 ways: from 10 to 100
Hz and from 60 to 0 Hz in ascending and descending test
respectively. ...
DANI: el resumen de este poster está publicado en la revista Cultura, Ciencia y Deporte que si tiene FI en SJR. Pero la cita la he hecho sobre el congreso en el que fue presentado y por tanto no he puesto el FI (he estado viendo ejemplos de poster en Abacus)y por eso he decidido hacerlo así.
