Comparison of Choice Reaction Time in Athlete and Non-athlete Females During an Incremental Exercise in Various Intensities

The purpose of this study was to compare the choice reaction time in athlete and non-athlete females during an incremental exercise in various intensities. Twenty healthy subjects were selected from the students of Guilan University. The first group was the athlete group with 10 subjects (age 22.6±1.07 years, weight 54.6±6.6 kg, height 161.2±3.6cm) who had at least two years activity in sports such as basketball, handball and volleyball. The second group was the non-athlete group which contained 10 subjects (age 23.3±1.4 years, weight 56.2±9.6kg, height 162±4.2cm) who had no background of regular exercise. Subjects were settled into an incremental exercise in various intensities on treadmill. Before and during the activity in each 30 seconds the researcher implemented two choice reaction time tasks. During the exercise in each stage, the subjectsʹ HR were recorded. The result of t-test and one-way ANOVA showed that choice reaction time was not significantly different in various intensities of exercise (%65, %73, %84, %91, %97 HRmax and exhaustion) also between the two groups there were no significant difference of intensity of exercise in which the best and worst choice reaction time can be gained (P>0.05). Therefore, we concluded that the intensity of incremental exercise has no significant effect on CRT of athlete and non-athlete femals.
