The effect of fatigue due to different intensities of exercise on coincidence-anticipation timing performance with intra trial variation

The aim of this study was to examine impact of different intensities of exercise fatigue on increasing and decreasing intra trial stimulus speed on coincidence-anticipation timing. Subjects were 15 volunteer students (20.33±0.97) years of Allameh Tabataba’i University. After sampling and choose proper software (coincidence-anticipation timing software) anticipation all subjects performed 1 block consist of 10 trial with intra trial variation under three fatigue conditions: rest, moderate-intensity and high-intensity exercise on treadmill until the participants reached a steady state of 50% and 80% of heart rate reserve (HRR), respectively. Data was analyzed with Kalmogorov- Smiranov Test normality and homogeneity of variance tests Levine test, repeated measure (ANOVA) and Bonferroni post hoc test frequently in significant level of (0.05). Results showed in increasing rate moderate intensity exercise-related fatigue (50%), variable error was not significant (P>0.05), but absolute error was significant (P0.05), but in high-intensity exercise related fatigue (80%) variable error and absolute error was significant(P
