The main aim of the present study was to implement an exergame program that uses Fitlight technology to identify the impact on motor, recognition, and cognitive reaction times in junior athletes practicing team sports: basketball, handball, and volleyball. The second aim was to identifying differences in progress of the three types of reaction time between female and male players through computerized tests. The study included 360 subjects for basketball, 130 athletes of which were 68 male subjects and 62 female subjects; for handball, 124 athletes of which 64 were male subjects and 60 female athletes; for volleyball, 106 athletes of which 48 male were subjects and 48 female athletes. Characteristics of the experimental players: average age ± SD 13.60 ± 1.07; average sports experience ± SD 6.24 ± 0.92. The research included an initial and a final test between which a program of exergames was implemented over a period of 3 months focused on optimizing human reaction times. The evaluation of the reaction times was carried out through three computer games, the results being processed in SPSS 22. The relevant results of the research: for the simple motor reaction time (MSRT), the greatest progress between tests was the volleyball group, and for women, it was the basketball group; for the recognition reaction time (RRT), the male handball group and the female basketball group recorded the greatest progress; for the cognitive reactive time (CRT), the greatest progress was achieved by the male and female volleyball players. In all tests, the progress of the female basketball, handball, and volleyball players showed superior progress to similar male players. The results of the research highlighted the effectiveness of the experimental exergame program by using Fitlight technology in optimizing human reaction times in junior team-game athletes. Using computer games to evaluate reaction times allowed us to differentiate the evaluation on the types of human reactions under both standardized conditions but also under conditions of efficiency and attractiveness.

The aim of the research was to implement an athletic program to improve the explosive force in order to optimize physical fitness at the level of elite football-tennis players and evaluate the progress made through specific tests using the Opto Jump. The research included 10 elite European and world-class players, on whom an experimental program was applied in order to improve the explosive force of the limbs in conditions of speed, endurance, and dynamic balance. Study tests: five vertical jumps on the spot, on the left/right leg; five back and forth jumps on the left/right leg; five left/right side jumps on the left/right leg; vertical jumps on both legs 60 s; BFS vertical jumps. For each test, the following parameters specific to the explosive force were statistically analyzed: contact time (s); flight time (s); jump height (cm), jump power (w/kg); RSI—Reactive Strength Index, defined as Height (m/s). In the study, the average value of the parameters specific to the jumps performed in each test was taken into account. During the study, the tests were performed and processed on the Opto Jump device and software. In all tests of the experiment monitored through Opto Jump, significant progress was made in the final test compared to the initial one, which demonstrates the efficiency of the physical training program implemented for the development of explosive force, with an impact on the sports performance of elite players. The most relevant results obtained for the left leg regarding the improvement of the explosive force of the lower limbs materialized in the jump height parameter was in the test of five vertical jumps on one leg on the spot, and for the right leg in the tests of: five back and forth jumps and five left/right side jumps. The most significant advances in the study were in the tests, in descending order of their weight: 60 s vertical jumps on both legs; five back-and-forth jumps and five left/right side jumps, five vertical jumps on one leg standing, and BFS vertical jumps.

The aim of the research was to identify the effect of 4vs.4 small-sided games (SSGs) with goalkeepers (4vs.4+GK), applied twice a week, for 8 weeks, on U18 football players’ physical ability, compared to that of the athletes who performed specific aerobic endurance training. The research included 40 football players U18, divided into two groups: 20 in the experiment group (EG) aged 17.49 ± 0.61 years and 20 in the control group (CG) aged 17.66 ± 0.54 years. From the initial test (IT) to final tests (FT) performed on the parameters, maximum oxygen consumption (VO_2max) and 10 m and 20 m sprint and agility with and without a ball showed a significant increase for both groups. The first and last SSG training was monitored, using total distance (TD), high-intensity distance (HSR—high-speed running) and maximum intensity distance (VHSR—very-high-speed running). Comparative analyses of EG and CG parameters at the FT shows that the differences between the means of two groups are statistically significant in favor of the experimental group in terms of all parameters, except 10 m sprint (p < 0.05). Referring to SSGs, the experimental group had a 7.78% increase rate in TD (p < 0.0005), a 30.90% (p < 0.0005) increase rate with HSR and no significant differences (p > 0.05) with VHSR. The experimental training program of 4vs.4+GK SSGs, applied to U18 football players, produced significant progress in the physical, and functional parameters.

The present study analyzed the relationships among material difficulties, job insecurity, work meaning and the mental health of sports coaches. Participants for this study were 200 coaches (120 men and 80 women, aged between 18 and 60 years, M = 41.04, SD = 8.71). The instruments used were (a) The Difficulties List, (b) Qualitative Job Insecurity, (c) Quantitative Job Insecurity, (d) The Work and Meaning Inventory, Depression, Anxiety, and Stress Scales. Statistical analysis was performed through SPSS 24. The results obtained by three multiple mediations showed that material difficulties were not directly associated with depression, anxiety, and stress. Although qualitative job insecurity mediates the relationship between material difficulties and mental health (β = 0.14, p < 0.01 for depression, β = 0.17, p < 0.01 for anxiety, and β = 0.14, p < 0.01 for stress) quantitative job insecurity and work meaning do not mediate this relationship but had significant direct effects. The conclusions of the study led to the need for material and psychological support for coaches to have a meaningful activity, so that they could achieve significant performance with their athletes.

Physical performance regarding the rankings of U16 junior tennis players is not precisely understood. The purpose of this preliminary research was to check if the top-ranked players had better results in the evaluation of physical tests than the lower-ranked ones. Therefore, the scope was to determine if the national ranking is related to the physical characteristics. The physical tests used were approved by the Romanian Tennis Federation. The following research methodology has been used: protocol methodology, the recording of data in research methodology, test in research methodology, and the statistical methodology. The tennis players followed their usual physical training for three months and at the end of this period, they were tested. Twenty-two tennis players, eleven girls, and eleven boys, between 14 and 16 years old, were part of this preliminary research. The following measures were conducted: 5-10 m sprint, 30 m sprint test, 6 x 20 m sprints, long jump, repeated lateral jumps performed on both legs over the gym bench, one-handed medicine ball throw with, overhead medicine ball throw test, lateral steps test, Hexagon test, agility test, and push-ups test. Results The group of tennis players was followed during 12 weeks of their usual training. The variables were expressed in mean and standard deviation. The purpose was to check if there is any correlation between the ranking and the morphological parameters. Pearson correlation has been used. The normality of the variance and covariance was certified with Shapiro-Wilks Normality Test. Conclusion After comparing the results, it was shown that the players from the group with better ranking positions, had superior results in the evaluation tests.

DanceSport is part of the category of expressive sports, being in a continuous transformation and evolution, whose regulations are constantly adapting to society and to present times and offering a complex spectacle. For athletes – dancers to assert themselves on the dance floor, during competitions, many more elements and aspects are needed and not just their interest or desire to participate. Several mandatory conditions need to be considered, the first of which is staged selection, thus following the selection criteria of each stage. Given the diversity of forms that selection can take in expression sports (according to certain principles) and at the same time, taking stock of the most used terms in the field, we further set out certain models and classification criteria but also methods and forms of selection. In order to materialize the aforementioned information and without claiming to be exhaustive, we affirm that the nature of the evidence and its specificity but also, the new ways to learn and improve the process must be considered. In any sport, the selection is a long process that requires seriousness, perseverance, and exigency from all those who are involved, still, it is recommended to consider both the particularities of the sport and the particularities of each dancer.
