Elite sports environments can increase psychiatric conditions like stress and depression due to social pressure for specific body shapes, encouraging disordered eating behaviors, especially in endurance, aesthetic, and weight-dependent sports. This review aims to investigate eating habits among athletes suffering from poor mental health and identify dietary strategies or nutritional advice to mitigate these conditions in physically active individuals. The review focused on studies conducted after 2010 involving adults in any level of regular physical activity, showcasing psychiatric symptoms related to a disordered relationship with food, including depression and various eating disorders. The search on the literature databases was conducted on 20th October 2023 through multiple electronic databases (PubMed, SCOPUS, and Google Scholar) to capture as many relevant citations as possible. Exclusions were made for studies on children or psychiatric patients. The research was sourced from significant databases, emphasizing the correlation between dietary habits and mental health in athletes. Findings reveal that athletes, particularly in ultra-endurance and weight-dependent sports, are susceptible to psychiatric disorders such as depression, anxiety, and exercise addiction. Competitive bodybuilders also showed higher levels of depression and orthorexia nervosa symptoms. Tailored nutrition therapy, guided by healthcare professionals and adjusted to each athlete's specific needs and preferences, is crucial for addressing psychiatric symptoms and eating disorders in athletes. A holistic approach to recovery and well-being can significantly enhance both performance and overall quality of life, underscoring the importance of high-quality, balanced diets in supporting mental health and athletes' achievement.

Background and Study Aim. The consumption of nitrate has been linked to various advantages, including aiding recovery by lessening fatigue, enhancing oxygen supply to muscles, and increasing the elimination of metabolic by-products during intense physical activity. Given the rising trend of utilizing dietary supplements for peak athletic performance, this literature review aims to explore the role and promise of nitrate supplementation in influencing muscle function and boosting physical prowess, while also shedding light on its potential perks and drawbacks.Material and Methods. Electronic databases including Web of Science (all databases), PubMed, Scopus, Google Scholar, Science Direct, were explored on June 11, 2022. The search terms were drawn from prior systematic reviews on nitrate supplementation and exercise and informed by a recent narrative review on Nitrates impact on athletic performance and muscle hypertrophy.Results. The findings of this review indicate that nitrate intake, owing to its ability to widen blood vessels, could potentially enhance blood flow and oxygen delivery to muscles during exercise. Consequently, this improved circulation might facilitate better nutrient and oxygen transportation to muscle tissue, thereby fostering muscle development through enhanced nutrient absorption and waste removal during physical exertion. However, it's crucial to note that excessive nitrate consumption might trigger adverse effects related to the formation of nitrosamines.Conclusion. In summary, investigations into the potential advantages of nitrate supplementation, whether through dietary sources or supplements, in augmenting athletic performance are promising. This is evident from the observed effects of increased muscle protein synthesis, reduced muscle soreness, and enhanced cognitive function under stressful conditions. Nonetheless, it's imperative to exercise caution against over-supplementation due to the potential risks of toxicity and associated side effects.

Background and Study Aim. Branched-chain amino acids (BCAAs) have received considerable attention in sports science due to their potential benefits in improving athletic performance and promoting muscle recovery. BCAAs including leucine, isoleucine, and valine, are essential amino acids that are important for muscle protein physiology. To date, studies have shown positive effects of BCAAs supplementation on muscle recovery, muscle soreness, and cognitive function. Hence, with the growing popularity of using dietary supplements for optimal athletic performance, this narrative literature review aims to investigate the role and potential of BCAAs supplementation to influence muscle function and improve physical performance, while highlighting the potential benefits and side effects associated with their supplementation.Material and Methods. The current review was conducted according to PRISMA (Preferred reporting items for systematic review and meta-analysis) guidelines. Electronic databases including Web of Science (all databases), PubMed, Scopus, Google Scholar, Science Direct, were explored on June 11, 2022.Results. Based on recent evidence, BCAAs have been shown to reduce muscle damage, improve muscle recovery and repair, increase muscle protein synthesis, and maintain muscle mass during periods of energy restriction, however may also have some potential side effects such as liver damage, kidney dysfunction and negative effects on glucose metabolism.Conclusion. In conclusion, studies investigating the potential benefits of BCAAs obtained from supplementation and diet to improve athletic performance are promising due to their demonstrated effects in increasing muscle protein synthesis, reducing muscle soreness, and improving cognitive function under stress.

Background and Study Aim. Coaches play a critical role in athlete development, yet coaching education in the Philippines remains fragmented, decentralized, and under-regulated. Despite the growing success of Filipino athletes on the international stage, the absence of a national framework has resulted in inconsistent certification standards, limited access to continuing professional development (CPD), and uneven opportunities for career progression. This study aims to address this gap by proposing a unified National Coaching Education Framework (NCEF) for the Philippines. Material and Methods. The study employed a policy-oriented approach that combined a structured literature review with comparative policy analysis of international models such as Canada"™s National Coaching Certification Program (NCCP), the United Kingdom"™s Coaching Certificate (UKCC), and Singapore"™s Continuing Coach Education (CCE) Program. Thematic analysis was conducted across academic literature, government reports, and institutional documents. Results. Findings reveal four critical issues: (1) fragmentation and lack of standardization in certification, (2) limited access to CPD, (3) inequities in affordability and regional accessibility, and (4) a disconnect between academic preparation and applied coaching practice. Based on these insights, the proposed NCEF introduces a tiered certification system"”community, developmental, and elite/high-performance coaches"”supported by mandatory CPD, ethics, and safeguarding standards. Conclusions. This framework contributes to the professionalization of coaching in the Philippines while aligning with international benchmarks. It also provides practical implications for policymakers and institutions, offering a pathway toward a more equitable, accountable, and sustainable coaching system.
