Thus the aim of this study was to determine the role of mental toughness of open and closed skill athletes. To obtain data, the investigators had selected Two hundred and nine (N=209) male inter-college level athletes of 20 to 25 years of age group were selected to act as subjects. They were further divided into two groups which includes n=130 open skill athletes and n=79 closed skill athletes of various games and sports. The purposive sampling technique was used to attain the objectives of the study. All the subjects, after having been informed about the objective and protocol of the study, gave their consent and volunteered to participate in this study. To determine the significant differences between open and closed skill athletes, unpaired t-test was employed for data analyses. For testing the hypotheses, the level of significance was set at 0.05. It is concluded from the above findings that insignificant differences were found with regard to mental toughness of open and closed skill athletes in the sub-variables; i.e. reboundability, ability to handle pressure, concentration, confidence, motivation and overall mental toughness.
