  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.

  Psychological well-being and aggression in handball players: examining the mediating role of exercise addiction

  Objective: This study aimed to examine the relationship between psychological well-being and aggression among handball players and to determine whether exercise addiction mediates this relationship. Methods: A descriptive, cross-sectional, and correlational design was used. The population consisted of players competing in the Turkish Handball Leagues during the 2024–2025 season, and 442 athletes participated using a non-probability sampling method. Data were collected via an online survey including a personal information form, the Psychological Well-Being Scale, the Buss–Perry Aggression Questionnaire, and the Exercise Addiction Inventory. Results: Psychological well-being showed a significant negative correlation with aggression (r = −0.242, p < 0.001). Exercise addiction was positively associated with both psychological well-being (r = 0.212, p < 0.001) and aggression (r = 0.105, p = 0.027). Mediation analysis indicated that exercise addiction significantly and partially mediated the relationship between psychological well-being and aggression (indirect effect 95% CI: 0.0246–0.1654). The direct effect of psychological well-being on aggression remained significant (β = −0.7093, p < 0.001). Conclusion: Higher psychological well-being was associated with lower aggression among handball players, whereas exercise addiction was associated with both higher psychological well-being and higher aggression and emerged as a partial statistical mediator of this relationship. These findings may help inform future studies and preventive strategies focusing on athlete mental health and behavioral regulation. However, because of the cross-sectional design, causal inferences cannot be drawn.
