In recent years, technology-based initiatives have provided children and adolescents with a compelling and viable way to encourage PA. Based on the results of previous research, we have conducted this review to gain a better understanding of if and how specific commercially available wearable devices impact physical activity promotion and health in children and adolescents. We have conducted this review, that was based on a theoretical framework of the self-determination theory (SDT), and focused on the impact that wearable devices have on physical activity promotion and health. The electronic databases of Google Scholar, Web of Science, and PubMed were searched between 2010 and 2023 for all available literature. Eleven studies overall satisfied the requirements for inclusion criteria. The sa...

Methods: The sample of participants consisted of 10 male judokas (Age = 20 ± 2.1 years) who are judo masters (black belt holders) with a minimum of 10 years of training and competition experience. The study was designed as a double-blinded crossover design with the order of treatments being randomly assigned. The washout period was 72 h. All subjects received a dose of sodium bicarbonate (0.3 g/kg body weight) or a placebo 120 min before the fatigue caused by the special judo fitness test (SJFT). Lactate concentration (LC), countermovement jump (CMJ), hand grip strength and degree of perceived fatigue on Borg’s scale (RPE) were tested two times before SJFT and four times after SJFT. Results: There was no interaction between groups and type of recovery at any time during the two types of recovery for RPE, grip strength, VJ and lactate concentration (p > 0.05)....

The aim of this study was to establish if sodium bicarbonate affects the blood marker levels after a Special Judo Fitness Test in elite judo athletes. Material and Methods. Ten male judo athletes (age 20 ? 2.1 years; body height 180.18 ? 8.11 cm; body mass 85.24 ? 23.17 kg; body mass index 25.2 ? 3.4 kg/m2), judo masters (black belt holders) with at least 10 years of training and competition experience, agreed to participate in the current research. Results. The results showed a significant main effect of time (p < 0.05) for the following variables: uric acid, aspartate aminotransferase, alanine transaminase, creatine kinase, lactate dehydrogenase, phosphate, magnesium, calcium, sodium, potassium, and chloride. We found that creatine kinase, C-reactive protein, sodium and chloride were significantly different (p < 0.05) in the sodium bicarbonate group compared to placebo group after the Special Judo Fitness Test. Conclusion. The main finding of the present study ...
