Background: In the field of sports, controlling an individual's emotions is an essential skill for effective performance. It is therefore crucial to understand the current situation of athletes and thus provide better training and emotional regulation resources. Objective: The research aims to determine the role of athletic mental energy in psychological resilience and to reveal its relations with each other and with some variables. Methods: The study group of the research consists of a total of 462 athlete-students (age 21.36 ± 1.49 years), 138 (29.9%) females and 324 (70.1%) males. The Brief Resilience Scale and the Athletic Mental Energy Scale (AMES) were used in the study. Descriptive statistics, t-test and multiple linear regression analysis were applied for data analysis. Results: In the research findings, the positive correlation between psychological resilience and all sub-dimensions of the AMES was statistically significant. In the regression model, the significant effect of athletic mental energy on the prediction of psychological resilience was determined (F(6, 455) = 12.06, p < .001, R2 = .14). It was observed that the males' mean scores in the AMES (calmness) sub-dimension and psychological resilience were higher than those of females while females' mean scores in the AMES (motivation) sub-dimension were higher than those of males. Conclusions: In general, we suggest that athletic mental energy contributes significantly to psychological resilience. In addition, it can be said that the predictability of concentration and calmness on psychological resilience is higher than the other sub-dimensions of athletic mental energy.

To determine the statistical relationships among different consolidated performance tests (Yo-Yo, jump, sprint and agility), and the Powersprint™ device, an isotonic equipment, usually used to increase the muscular strength of athletes, used here as performance test. One hundred individuals were involved in the tests (16 females and 84 males). Ninety-five subjects were practicing different field sports, whereas 3 female and 2 male subjects were inactive. Gender, height and body mass were recorded. Participants completed the following tests: Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1 and PowerSprint 3.0™. Results of this experiment highlighted that PowerSprint 3.0™ is positively and significantly correlated with Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1. Additionally, the principal component analysis, as expected, was able to neatly differentiates between male, female and inactive subjects. The selected tests appeared particularly effective in giving information about athlete performances in soccer. Performances measured with the PowerSprint 3.0™ positively and significantly correlated with jumps, COD, sprint and YYIR1 tests. This is an indication of the possible use of this light, inexpensive and portable instrument for measuring athlete performances and checking the effectiveness of training programs.
