The purpose of this study was to evaluate the effect of 8-week β-alanine supplementation on C-Reactive Protein (CRP), interleukin-6 (IL-6), body composition, and bio-motor abilities in elite male basketball players. Twenty male basketball players (age: 23 + 0.6 years; body mass: 78.3 + 4.8 kg; height:185.3 + 5.4 cm, %BF, 15.2 ± 4.8) volunteered to participate in this study. They were divided into a β-alanine group (BG, N = 10) and a placebo group (PG, N = 10). All players were preparing for university competitions and had played for over five years. Players used 6.4 g/d of β-alanine in BG and maltodextrin in PG. The participants were involved in regular basketball training three months before the study. CRP, IL-6, body composition parameters, and bio-motor abilities were measured before starting the exercises and after completing the eight-week training period. The research findings showed a significant decrease in CRP and IL-6 and an increase in anaerobic peak power between the pre-test and post-test, as well as between BG and PG groups (p < 0.05). Although the other measured factors were a relative improvement compared to the pre-test and also compared to PG, these changes were not statistically significant (p < 0.05). Eight weeks of β-alanine supplementation ameliorated increases in IL-6 and CRP associated with in-season physical stressors in collegiate basketball players. These changes in pro-inflammatory cytokines suggest that β-alanine supplementation may be a useful nutritional strategy for immune regulation and can also improve anaerobic performance compared to PG.

This study aimed to evaluate the effects of jump rope training on cardiovascular capacity, assessed with the Ruffier test, and muscular strength, measured using isometric dynamometry (BioFET Mustec, Almere, The Netherlands), within a university physical education program. A total of 52 undergraduate students from non-specialist faculties at the University of Oradea were randomly assigned to either an experimental group (EG) or a control group (CG). Over eight weeks, the EG performed a ten-minute jump rope training session once per week in combination with cardiovascular exercises, while the CG participated only in cardiovascular exercises. Statistical analyses revealed a significant group effect on cardiovascular response (Ruffier Index: p = 0.019; Cohen’s d = −0.271) and a substantial increase in right lower limb strength (p = 0.003; d = 1.026) in the EG compared to the CG. Furthermore, improvements were observed in upper limb strength (left arm: p = 0.010; d = 0.922) and left lower limb strength (p = 0.027; d = 0.779). These findings suggest that incorporating jump rope training into university physical education classes may represent an effective and low-cost strategy to enhance both cardiovascular efficiency and muscular strength in young adults. Given its simplicity and affordability, jump rope training appears feasible for implementation in schools and universities, even where resources are limited. Future research should investigate its long-term effects across different populations.

Background/Objectives: Agility and reaction speed are critical components of sports performance and are influenced by both physical conditioning and psychological state. Interventions such as SmartACT, which integrate mindfulness, acceptance, and commitment, guided imagery and hypnosis techniques are still underexplored in high-performance sport, despite their potential to affect both psychological and motor dimensions. Methods: This 7-week controlled trial investigated the effectiveness of SmartACT in reducing psychological and somatic symptoms and enhancing motor performance in adolescent athletes. A total of 193 athletes aged 15–18 years were assigned to three groups: SmartACT (n = 69), MAC (Mindfulness–Acceptance–Commitment, the standardized Gardner & Moore protocol; n = 65), and a control group (n = 59). Agility was measured using the T-Drill Agility Test with Microgate electronic timing, and reaction speed was assessed using BlazePod devices. Psychological and somatic symptoms were evaluated using the Depression, Anxiety, and Stress Scale (DASS-21) and the Ghent Multidimensional Somatic Complaints Scale (GMSCS). Results: The SmartACT group showed significantly improved agility (MD = −1.07 s, p < 0.001, d = 2.50, 95% CI [1.79, 3.35]), faster reaction times (MD = −643.75 ms, p < 0.001, d = 0.85, 95% CI [0.35, 1.41]), and a higher number of BlazePod touches (MD = +2.53, p < 0.001, d = 1.43, 95% CI [0.87, 2.07]). Psychological symptoms (DASS-21) and somatic complaints (GMSCS) decreased significantly more than in the MAC and control groups. Conclusions: SmartACT appears to be an effective hybrid psychological intervention to simultaneously improve physical performance and reduce psychological and psychosomatic distress in adolescent athletes.

Limited research has explored the impact of balance training on young alpine skiers, despite its recognized importance in the sport. This study evaluated the effects of a 10-week dry-land balance training program on the balance and skiing technique of skiers aged 9–11 years. The program employed five training modalities: neuromuscular, plyometric, core stability, proprioceptive, and equipment-based balance training. Thirty participants were divided into experimental and control groups based on their initial SKI IQ scores. The assessments included static balance (BTS P-Walk), explosive power (BTS G-Walk), and on-snow metrics (SKI IQ; balance, pressure, and edging) using CARV technology. The statistical analysis revealed significant improvements in the experimental group for the SKI IQ (F = 13.239; p = 0.001; η² = 0.321) in terms of the balance metric (F = 4.800; p = 0.037) and pressure metric (F = 8.084; p = 0.008), and for the static balance parameters, such as mediolateral stability in a two-legged stance (F = 4.304; p = 0.047; η² = 0.133) and anteroposterior stability in eyes-closed conditions (F = 14.249; p = 0.001; η² = 0.337). The single-leg stance stability and explosive force (F = 6.08; p = 0.02) also showed marked enhancements. The edging performance, however, showed no significant change. This study underscores the value of balance training for enhancing young skiers’ performance metrics and highlights wearable technology as an effective tool for real-time feedback. Integrating balance-focused programs into alpine skiing preparation can boost performance.

Background: Executive functions, notably attention and processing speed, are essential for athletic performance, especially in sports that require quick reactions and decision-making under pressure. The current study aims to assess the impact of the SmartACT program—a psychological intervention that includes acceptance and commitment therapy, hypnosis, and guided imagery—on attentional processes and psychological flexibility in adolescent student-athletes. Methods: This 7-week quasi-experimental controlled study investigated the efficacy of SmartACT in adolescent student-athletes aged 15 to 18. A total of 309 individuals were divided into three groups using convenience sampling: SmartACT (n = 93), MAC (Mindfulness–Acceptance–Commitment, the standardized Gardner & Moore technique; n = 109), and control (n = 107). The d2 test was used to examine attention and visual processing, while the Acceptance and Action Questionnaire—II (AAQ-II) was used to assess psychological flexibility, both before and after the intervention. The data were analyzed using mixed-design repeated-measures ANOVA and paired-samples t-tests. Results: The SmartACT group showed significant improvement on both tests, specifically in the total number of items processed in the d2 test (457.83 to 600.24; p < 0.001), and experiential avoidance, measured by AAQ-II, decreased (18.48 to 12.80; p < 0.001), indicating increased psychological flexibility. Conclusions: The main findings of our study suggest that integrating ACT with hypnosis and imagery may enhance cognitive attentional functions and psychological flexibility in adolescent student-athletes.

Background/Objectives: Whether coordination-based training can develop group cohesion in youth sport, and how cohesion relates to peripheral oxytocin, is unclear. We examined cohesion and salivary oxytocin during a six-month coordination- and cohesion-oriented program in junior handball players. Methods: Sixty-four male players (12–14 years) from four clubs joined a prospective, non-randomized, within-club controlled study (not prospectively registered). In each club, one pre-existing training slot (eight players) formed the experimental group (EG; n = 32) and the other the control group (CG; n = 32). For 24 weeks (three sessions/week), EG replaced 20–25 min of technical–tactical work with coordination, cooperation, and interpersonal-synchrony exercises. The primary outcome was Youth Sport Environment Questionnaire (YSEQ) Task Cohesion. Results: In the baseline-adjusted, cluster-robust analysis, T1 Task Cohesion was 0.72 points higher in EG than CG (95% CI 0.22–1.23; p = 0.010); Social Cohesion differed similarly (adjusted difference 0.77 points; 95% CI 0.33–1.22; p = 0.003). The adjusted oxytocin difference was imprecise and non-significant (5.0 pg/mL; 95% CI −0.01 to 10.02; p = 0.050), and oxytocin change was unrelated to Task Cohesion change. Conclusions: The program was accompanied by a more favorable cohesion trajectory than time-matched standard training. Non-randomized allocation precludes causal conclusions; oxytocin findings remain exploratory.
