Abstract
Purpose: The aim of this study was to investigate the relationship between cardiorespiratory endurance and speed with the mediation of mental stubbornness on the decision-making accuracy of Futsal Premier League referees.
Methods: In the present study, 123 judges (37 females and 86 males) participated in this study voluntarily. The judges completed a hardiness questionnaire and then took the speed and endurance test, and finally their decision-making accuracy was assessed by a video test.
Results: The results of path analysis with PLS software showed that there is a positive and significant causal relationship between cardiorespiratory endurance and futsal referees' decision accuracy (P = 0.000, T = 4.03, b = 0.37). There is a positive and significant causal relationship between cardiorespiratory endurance and mental stubbornness of futsal referees (P = 0.000, T = 4.03, b = 0.42). Mental toughness plays a positive and significant mediating role between cardiorespiratory endurance and decision making accuracy (P = 0.039, T = 2.07, b = 0.07). There is a negative and significant causal relationship between the physical fitness factor of speed (time) and the accuracy of futsal referees' decision making (P = 0.000, T = 3.53, b = -0.33).
Conclusion: It can be concluded that cardiorespiratory speed and endurance both play an important role in the decision-making accuracy of male and female judges and also mental toughness has a positive and significant mediating role between cardiorespiratory endurance and decision-making accuracy.
