The purpose of the present study was to investigate effects of both local and generalphysical fatigue on visual simple and visual choice reaction time of elite level athletes. 15male and 3 female national Muay-Thai athletes (M
age
= 21.55, SD= 3.47) who participated atleast 5 training sessions per week volunteered to participate present study. Subjects wereasked to perform Wingate anaerobic test on a mechanically braked cycle ergometer (834 E,Monark) to induce general fatigue. Hand grip dynamometer was used for resistance exercisesto induce local fatigue. Simple, two-choice and three-choice visual reaction times weremeasured at resting, after local and general physical fatigue conditions both on right and lefthands, respectively. The results of repeated measure ANOVAs yielded that compared toresting conditions simple reaction time significantly increased after inducing the local andgeneral physical fatigue on both hands. On the other hand, although two-choice and three-choice reaction time mean scores increased from resting to both general and local physicalfatigue conditions, these increments were not statistically different among measurements.
Itwas concluded that both dynamic and resistance exercise induced fatigue may seems tolengthen only simple reaction time and did not affect decision making processes of elite levelMuay-Thai athletes
