Purpose: The present study was conducted to investigate the effect of throw distance, mental fatigue and muscular fatigue on throw accuracy and movement time in dart throwing skill.
Methods: This is a quasi-experimental research with a pretest-posttest design. Twenty eight right-handed male and female participated in this study. They had no regular experience in throwing darts. Data were collected from the dart throwing task in six experimental conditions. After checking the normality of data distribution, 3x2 analysis of variance test was used with repeated measurements at a significance level of 0.05.
Results: The results showed that the main effect of fatigue (p = 0.001) and the main effect of throw distance (p=0.001), was significant on the throwing accuracy. However, no significant interaction effect was observed (p=0.401). Also, the main effect of fatigue (p = 0.001) and the main effect of throwing distance (p = 0.001) on movement time were significant. However, no significant interaction effect was observed (p = 0.909).
Conclusion: Mental and muscular fatigue can negatively affect the performance accuracy. On the other hand, the movement time decreases by reducing the amount of force during muscular fatigue. Also, increasing the throw distance can reduce the movement time to produce the required force and thus reduce the throw accuracy.
