Introduction: Taekwondo is a complex combat sport requiring high levels of strength, balance, reaction time, attention, agility, and endurance for effective performance under rapid offensive and defensive conditions. This study aimed to investigate the effects of an 8-week plyometric training program on static balance (SB), dynamic balance (DB), reaction time (RT), and attention (AT) in adolescent female taekwondo athletes. Methods: Twenty female athletes (age: 14.85 +/- 1.53 years; height: 162.27 +/- 7.12 cm; body mass: 56.69 +/- 6.45 kg) voluntarily participated in the study at Mardin Halit Demir Martial Arts Club. Participants were randomly assigned to either an experimental group (EG, n = 10) or a control group (CG, n = 10). The EG performed plyometric training twice weekly for 8 weeks in addition to regular taekwondo training, while the CG continued only taekwondo training. Static balance was defined as the primary outcome, whereas dynamic balance, reaction time, and attention were considered secondary outcomes. A 2 & times; 2 repeated-measures analysis of variance (group & times; time) was used to examine intervention effects. Results: Significant group & times; time interactions were observed for static balance and dynamic balance (p < 0.05), favoring the experimental group. However, no significant group & times; time interactions were found for reaction time or attention (p > 0.05). Discussion: These findings suggest that plyometric training may effectively improve balance performance in adolescent female taekwondo athletes, particularly static and dynamic balance. However, no significant effects were observed for reaction time or attention. Further studies with larger sample sizes are needed to clarify the potential effects of plyometric training on cognitive performance.

Background and Study Aim Material and Methods Understanding the impact of swimming exercises on post-Covid-19 respiratory function is crucial for optimizing recovery strategies in affected individuals. The aim of this study is to determine the effect of 8-week swimming exercises on respiratory function parameters in adult individuals who have had Covid-19 disease. Sixteen male students, aged 19-21, voluntarily participated in the study. Eight participants were assigned to the experimental group (EG), and eight to the control group (CG), all of whom were students of the Faculty of Sports Sciences at the University. The EG underwent an 8-week swimming exercise program conducted at the Bingol Youth and Sports swimming pool (25 meters), three days a week. The CG was not involved in any exercise regimen. Pulmonary function tests (FVC, FEV1, FEV1/FVC, PEF) were conducted using a Cosmed Pony FXdel 2016 spirometer, one day before and one day after the exercise program for both EG and CG. Data analysis was performed using Independent Samples and Paired Samples T tests in SPSS 25, with a significance level set at p < 0.05. Results A statistically significant increase in respiratory FVC, FEV1, FEV1/FVC, and PEF function values was observed in the experimental group (EG) after the exercise intervention (p < 0.05). This increase was observed when comparing these values to their pre-exercise measurements. In contrast, there was no statistically significant difference in respiratory function results before and after exercise in the control group (CG) (p > 0.05). Conclusions The findings of this study highlight the therapeutic potential of an 8-week swimming exercise program in significantly enhancing respiratory function among adult individuals who have previously contracted Covid-19. These results offer valuable insights for the development of post-Covid-19 rehabilitation protocols, emphasizing the importance of regular exercise, such as swimming, in the recovery process.
