Published: Jan. 31, 2025

Imposing constraints such as limiting dribbling in smallsided games (SSGs) is known to increase physiological and locomotor demands. However, the long-term effects on physical adaptations remain unexplored. This experimental study aimed compare impact of free-play SSGs (freeD) limited-dribbling (limitedD) aerobic anaerobic youth basketball players. Forty-five players (aged 15.7 ± 0.6 years, with 4.2 0.7 years experience) were randomly assigned two groups (freeD limitedD) a control group (not exposed SSG interventions). During eight-week intervention, participated additional sessions twice week, session work time durations ranging from 12 16 min. Both followed identical formats, court dimensions, training regimens, only difference being that one free play while other was prohibited during progression. Aerobic capacity assessed using Yo-Yo Intermittent Recovery Test Level 1 (YYIRT), 30-second Wingate measured peak power output (PPO) average (APO) at baseline post-intervention. Statistical analysis conducted mixed ANOVA examine interactions between group. Comparisons YYIRT post-intervention revealed limitedD performed significantly better than both freeD (p = 0.035; d 1.038) < 0.001; 2.050), also showed performance 0.021; 0.082) Regarding PPO, 0.043; 0.943). Finally, for APO, 0.928) 1.793), exhibited 0.046; 0.036). Limiting more effective play. makes it potentially valuable strategy designing training. Coaches may consider incorporating conditions into boost intensity sessions, improve cardiovascular endurance, enhance power.

Published: Feb. 9, 2025

This study aimed to investigate the uniformity of adaptive changes in cardiorespiratory fitness and anaerobic power high-intensity interval interventions (HIIT) designed using techniques specified for soccer players. Thirty well-trained athletes (age = 25 ± 3.1 years; body mass 82.4 3.4 kg; height 183 2.1 cm) were randomly assigned two experimental groups engaging intervention individualized 30–15 Intermittent Fitness Test [HIITvIFT (two sets 5–8 min intervals, comprising 15 s running at 95% VIFT followed by passive recovery)], small-sided game with matched timing (SSG [4 2.5–4 3 v efforts]), as well an active control group. Before after a 6-week consisting three sessions per week, participants underwent lab-based test breath-by-breath gas analyzer non-invasive impedance cardiography evaluate aerobic cardiac function measures. Also, was measured lower-body Wingate test. Both resulted significant enhancement all measures over training period. Analyzing inter-individual variability through determining residuals individual indicated HIITvIFT results ventilatory threshold (VT [first (VT1) second (VT2)]), peak average output than SSG (p 0.02, 0.04, 0.01, respectively). In addition, change maximum oxygen uptake, maximal ventilation, following notably greater 0.002, 0.006, and, 0.019, There no difference between hemodynamics (cardiac stroke volume). Overall, facilitating more homogenous stress, identical physiological demands uniform adaptations SSG.

Effects of Combined Versus Single Supplementation of Creatine, Beta-Alanine, and L-Citrulline During Short Sprint Interval Training on Basketball Players’ Performance: A Double-Blind Randomized Placebo-Controlled Trial

International Journal of Sports Physiology and Performance, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 9

Published: Jan. 1, 2025

Purpose : Athletes often use sport supplements to improve their physical and physiological performance. This randomized, double-blind, placebo (PL) -controlled study aimed investigate the effects of combined versus single supplementation creatine (Cr), beta-alanine (BA), L -citrulline (L-Cit) during short sprint interval training (SSIT) on basketball players’ performance over a period 28 days. Methods Forty-eight players were equally assigned 6 groups Cr (0.1 g/kg monohydrate daily), BA (4.8 g L-Cit (6 supplementation, PL, an active control group, each group consisted 8 participants. The participated in SSIT (3 sets 10 repetitions 5-s all-out runs) sessions 3 times week for 4 weeks.

Results All (Cr, BA, L-Cit, combined, PL) showed significant improvements 4-week intervention ( P < .05). Interestingly, supplement displayed significantly = .001) greater changes than PL indicating better outcomes adaptations. However, differences variables observed among groups. Conclusion Our findings indicate that short-term with Cr, as well combination them SSIT, can compared PL.
