Background: The burgeoning field of nutrigenomics offers a promising avenue for enhancing athletic performance through personalized nutrition plans tailored to an individual's genetic makeup. This study delves into the intricate dynamics between gene-diet interactions and their implications for athletes' performance, recovery rate, and endurance levels, thus contributing to the growing discourse on personalized sports nutrition and training regimens. Objective: The primary objective of this study was to investigate the impact of gene-diet interactions on sports performance, with a specific focus on understanding how these interactions influence athletes' recovery rates and endurance levels. The study aimed to provide empirical evidence to support the development of personalized nutrition and training strategies in the realm of sports. Methods: Utilizing a quantitative research design, this investigation analyzed data from 400 athletes, drawing on secondary sources, including the World Bank's extensive databases. Statistical analyses were conducted using the Statistical Package for the Social Sciences (SPSS) Version 25, encompassing descriptive statistics, Pearson correlation analysis, regression analysis, and factor analysis through Principal Component Analysis. This comprehensive methodological approach aimed to unravel the complex relationships between genetic variations, dietary patterns, and athletic performance metrics. Results: Descriptive statistics revealed a wide range of performance scores (50.57 - 99.60), recovery rates (1.02 - 9.99), and endurance levels (1.00 - 9.93), indicating significant variability among athletes. Correlation analysis demonstrated a modest but significant relationship between recovery rate and performance score (r = .140, p < .05), while regression analysis showed minimal explanatory power of gene variation and diet type on performance scores (R Square = .012). Factor analysis identified a latent factor predominantly influenced by recovery rate, suggesting an underlying trait affecting various aspects of athletic performance. Conclusion: This study underscores the complex and multifaceted nature of gene-diet interactions in influencing sports performance. The findings advocate for a more nuanced, personalized approach to nutrition and training, emphasizing the need for further research to explore a broader spectrum of genetic and dietary factors. The potential of nutrigenomics in sports underscores the importance of individualized dietary plans in optimizing athletic performance and recovery.

The scientific study analyzed the role of nutrition and the use of supplements in the training of powerlifters. After all, nutrition plays a key role in the training of powerlifters, affecting strength, endurance, recovery and overall sports performance. The article examines scientifically based principles of nutrition, the role of macro- and microelements, the effectiveness of sports supplements, and also presents the results of its own research on the influence of nutrition on strength indicators and recovery of athletes. Because modern sport, in particular powerlifting, is increasingly developing and gaining popularity among different groups of the population by age, gender, and level of training. The development of powerlifting in the USA, Ukraine and other countries is an indicator of society's demand for cultivating the cult of the body and its perfect functioning. Powerlifting is practiced by both amateurs and professional athletes. Their training systems are different and the body's reaction to power loads is individual. Therefore, it is relevant to analyze one of the many components of the powerlifter's training system, the role of nutrition and supplements. Because balanced nutrition and the use of supplements, and not the use of prohibited drugs, gives a natural increase in sports performance. Thus, it is relevant to study the long-term impact of different nutrition strategies on the sports results of powerlifters; study personalized approaches to nutrition depending on genetic factors; analyze the effectiveness of combined nutrition and training programs for maximum strength gains; assess the impact of micronutrients and vitamin complexes on the recovery and performance indicators of athletes.

Nutrition plays an important role not only in athletic performance but also in the recovery period. In terms of micronutrients, macronutrient intake and hydration and dietary supplements enhance both performance and recovery among athletes. Adequate nutrition influence muscles work, higher energy endurance and muscle strength besides supporting the recovery period after the exercise. The purpose of this research is to investigate the impact for various nutritional modifications in sports enthusiasts for carbohydrates and protein consumption, hydration, and supplementation on the martial arts’ performance and recovery, as well as other sporting activities. A randomized controlled trial (RCT) was conducted with 60 athletes from diverse sports, assigned to four intervention groups: carbohydrate loading, protein intake, proper fluid intake, and dietary supplementations including creatine, beta- alanine and branch chain amino acids. All the endurance, strength and recovery assessments such as time-to-exhaustion, one-repetition maximum (1RM) and blood lactate clearance were measured at baseline, halfway through the intervention and at the end. To evaluate the effectiveness of each intervention, data that were collected were also subjected to repeated measures ANOVA. Improvements were recorded in all the groups; however, the high carbohydrate group recorded the most pronounced improvement in endurance performance with time to exhaustion improving by 8. 2%. The high-protein group lifts significantly their strength by 9. 5% in 1RM squat whereas the supplementation group recorded the greatest enhancement in strength, power and recovery facets up to 12. 5% in 1RM bench press and muscle soreness decrease by 4. 2 points. These findings indicate that specific modifications in the diet in the form of carbohydrates for endurance runners and protein/creatine monohydrate for strength performers, can increase performance. Positive effects of hydration also became significant for endurance though their effects on the strength parameters were slightly smaller. The aids like creatine and beta-alanine are said to have shown significant results in enhancing strength, power and recovery. Proper nutrition really counts in an athlete’s abilities and even the time he takes to recuperate from an exercise. The best results can be achieved when nutritional strategies used are in line with sport and the athlete’s individual physiological adaptations. These findings make it beneficial for athletes and coaches to positively adopt sound progressive meal’s plan to enhance performance plus recovery time. Keywords- Nutritional Interventions and Their Effects on Athletic Performance and Recovery

The article addresses the importance of the specificity of sports nutrition and the consideration of its gender differences for optimizing athletes' nutrition to improve their performance, accelerate recovery, and reduce the risk of injury. The aim is to study the features of sports nutrition for martial arts athletes engaged in MMA, with an emphasis on gender aspects, in order to develop recommendations for optimizing dietary strategies to enhance athletic results and overall health. The results of a scientific analysis of specialized methodological literature are presented, examining how hormonal cycles (the menstrual cycle in women and testosterone levels in men) influence nutritional needs and athletic performance. Data on the impact of gender on the macro- and micronutrient requirements of MMA athletes are explored. Key aspects are developed, and practical recommendations are formulated for creating diets that optimize nutrition while considering gender aspects and aligning with the specific training needs of male and female MMA athletes. This includes assessing the nutritional needs of each athlete based on their gender, age, training goals, and physical indicators; developing and considering portion sizes and food quality; and maintaining a balance between energy needs and caloric intake. Hormonal cycles, particularly the menstrual cycle in women and fluctuations in testosterone levels in men, significantly influence the nutritional needs and athletic performance of combat sports athletes involved in MMA. Understanding these changes allows for the development of effective nutrition and training strategies that enhance performance and overall well-being. The application of evidence-based diets and nutritional strategies can significantly enhance competitive success in mixed martial arts. Vitamins and minerals have varying effects on recovery and performance in male and female combat athletes. Young male and female athletes have different needs for energy, macronutrients, and specific vitamins and minerals, influenced by both physiological and psychological factors.

Sleep is vital for the maintenance of physical and mental health, recovery and performance in athletes. Sleep also has a restorative effect on the immune system and the endocrine system. Sleep must be of adequate duration, timing and quality to promote recovery following training and competition. Inadequate sleep adversely impacts carbohydrate metabolism, appetite, energy intake and protein synthesis affecting recovery from the energy demands of daily living and training/competition related fatigue. Sleep's role in overall health and well-being has been established. Athletes have high sleep needs and are particularly vulnerable to sleep difficulties due to high training and competition demands, as such the implementation of the potential nutritional interventions to improve sleep duration and quality is commonplace. The use of certain nutrition strategies and supplements has an evidence base i.e. carbohydrate, caffeine, creatine, kiwifruit, magnesium, meal make-up and timing, protein and tart cherry. However, further research involving both foods and supplements is necessary to clarify the interactions between nutrition and the circadian system as there is potential to improve sleep and recovery. Additional research is necessary to clarify guidelines and develop products and protocols for foods and supplements to benefit athlete health, performance and/or recovery. The purpose of this review is to highlight the potential interaction between sleep and nutrition for athletes and how these interactions might benefit sleep and/or recovery.

This study aims to assess the impact of protein utilization and injury management on enhancing athletic performance and recovery in modern sports.

Keywords such as "Injury Management," "Protein Utilization," and "Athletic Performance" guided the search for relevant studies. The analysis reveals that adequate protein intake and balanced nutrition are vital for muscle repair, reducing muscle damage, and accelerating recovery following injury or intense exercise. The findings emphasize that effective nutritional strategies not only support recovery but also contribute to injury prevention and overall performance improvement. Personalized nutrition plans tailored to individual needs and specific conditions, including those of athletes with spinal cord injuries or from various sports disciplines, are crucial for optimizing outcomes. The study highlights that integrating protein and nutritional strategies into training and recovery programs can significantly enhance athletic performance and reduce the risk of injuries. Effective injury management, coupled with appropriate protein utilization, plays a pivotal role in achieving better recovery rates and improving overall health. By adopting these evidence-based strategies, athletes can better meet their performance goals and enhance their overall well-being. This research underscores the importance of a comprehensive and personalized approach to nutrition and injury management in sports health, offering valuable insights for optimizing athletic training and recovery practices

Background: Despite the well-documented benefits of exercise and sports participation, young athletes are particularly vulnerable to musculoskeletal injuries. This is especially true during periods of rapid growth, sports specialisation, and high training loads. While injuries are an inevitable aspect of sports participation, the risk can be minimised by promoting the development of strong, resilient tissues through proper nutrition and injury prevention strategies. Moreover, targeted nutrition strategies can accelerate recovery and rehabilitation, allowing for a quicker return to sports participation. Methods: This narrative review synthesises scientific evidence with practical insights to offer comprehensive dietary recommendations aimed at strengthening tissues and supporting the healing process during recovery and rehabilitation. The selection of all sources cited and synthesised in this narrative review were agreed upon by contributing author consensus, experts in sports nutrition (R.A., H.V., B.D.) and exercise and sports medicine (M.H.). Results: Key topics include factors that contribute to injury susceptibility, general dietary recommendations for growth and development, sports nutrition guidelines, and nutrition considerations during injury and rehabilitation. This review also addresses external factors that may lead to suboptimal nutrition, such as food literacy and eating disorders. Conclusions: By highlighting these factors, this article aims to equip coaches, nutritionists, dietitians, athletic trainers, physical therapists, parents/guardians, sporting organisations, and schools with essential knowledge to implement effective nutritional strategies for injury prevention, recovery, and rehabilitation, ultimately enhancing long-term health and athletic performance.

Enhanced literacy leads to healthier behaviors, particularly important for athletes. Variations in nutrition literacy among athletes across different sports disciplines are crucial for performance and well-being. Coaching emphasis, sport-specific demands, athlete demographics, and supplement use contribute to these variations, highlighting the importance of tailored education programs. Understanding athletes' knowledge and utilization of these aids, as well as their dietary practices, offers valuable insights into optimizing athletes’ performance. Factors such as the type of sport, individual preferences, and the availability of nutritional information play crucial roles in shaping athletes' decisions regarding ergogenic aid use. Conclusion: The connection between athletes' nutrition literacy and their use of ergogenic aids underscores the importance of tailored education and personalized nutrition plans for optimizing performance and well-being in sports.

Should Protein Be Included in CHO-Based Sports Supplements?

Purpose: This study provides a comprehensive overview of the dietary habits and nutritional requirements of athletes competing. The research aims to address the diverse scenarios athletes face, particularly in competitive sports, and explore recent advancements in sports nutrition accordingly. Research Methodology: A qualitative review was conducted, synthesising data from existing literature and evidence-based practices in sports nutrition. Key elements such as pre-race dietary strategies, energy replenishment protocols, and nutrient requirements for athletes in weight-specific sports were analysed. Additionally, metabolic pathways critical to athletic performance were examined to identify the most effective nutrients and supplements. Findings: The study highlights that optimal nutrition enhances athletic performance and recovery. Pre-race diets that emphasise easily digestible carbohydrates and rapid energy replenishment strategies post-exercise were found effective. Athletes in weight-categorised sports must carefully manage body weight while maintaining energy levels to sustain high performance. Supplements such as branched-chain amino acids, maltodextrin, and vitamins E and B12 were identified as beneficial in improving recovery and performance when integrated into a balanced diet. Managerial Implications: The findings underscore the importance of personalised dietary plans for athletes, tailored to the demands of specific sports and individual metabolic needs. Sports organisations and coaching teams can adopt these insights to develop effective nutritional protocols, optimising performance and recovery. Nutritionists working with athletes should also consider the unique challenges of weight maintenance and rapid energy replenishment in different sporting contexts.

In the past few years, much research has been conducted on edible mushrooms, among which Pleurotus ostreatus (PO)—also known as oyster mushrooms—has received attention due to its many health and medicinal benefits. Some research has shown that PO and its active compounds, such as lectins, polysaccharides, primarily β‐glucans, phenols, polyphenols, terpenoids, ergosterols, and glycoproteins, are strong immune system modulators, have anti‐inflammatory properties, and have potentially positive effects on the cardiovascular system and athletic performance. In this narrative review, an extensive search (academic databases from inception to April 25, 2024) was conducted in the scientific literature, and various aspects of PO and its effects on health and athletic performance were investigated. This narrative review article thereby demonstrates the potential benefits of PO for improving the overall baseline health and concomitant athletic sports performance, recovery, and cardiovascular system function. In addition to potential enhancements in antioxidant defense, substrate metabolism, and being a rich source of many essential nutrients, we describe a possible positive relationship between PO intake and improved athletic performance and recovery in athletes after intense exercise by reducing inflammation, modulating the microbiome, neutralizing free radicals, and strengthening the cardiovascular system. However, more research in basic studies and clinical trials is needed to investigate PO’s clinical applications, mechanisms, and effects on athletes.

Acceleration is a key determinant of performance in athletics and team sports (e.g., football, rugby). Resisted sprint training has gained significant attention as a method to enhance acceleration, typically through the addition of external resistance, such as sleds or resistance devices. Recent focus has been on heavy resisted sprint training (HRS), defined by resisted loads ≥30% body mass (BM) or ≥30% velocity decrement (Vdec). However, the long-term effects of HRS compared with non-resisted sprint training (NRS) on acceleration performance and kinematic adaptations remain inconclusive. This review with meta-analysis aims to review the current literature on intervention studies investigating the effects of HRS on acceleration performance and kinematics. This review with meta-analysis followed the PRISMA guidelines. Literature was searched up to and including December 30, 2024, using PubMed, Web of Science, and SPORTDiscus. Inclusion criteria were applied: (1) a longitudinal study over a minimum of 4 weeks; (2) studies using resistance (sleds, towing devices) and load intensities of ≥30% BM or ≥30% Vdec; (3) measurement of acceleration(030m) measured in (s) with a minimum distance of 5 m, or kinematic changes such as stride length, stride frequency, contact time, and flight time; (4) peer-reviewed studies. Eleven studies were included in this review, assessing changes in acceleration performance and kinematics. Results showed that HRS enhanced stride length, stride frequency, and 10-m sprint performance (P < 0.05low heterogeneity). HRS showed significant improvements in 10-m sprint performance compared to NRS. However, no significant improvement was observed in kinematics such as gait and joint angles (trunk angle, hip angle, and push-off angle) (P > 0.05). Our findings align with existing literature, confirming that HRS provides an effective load stimulus for enhancing acceleration performance. Specifically, HRS significantly improves sprint performance in the initial 10 m of acceleration by optimizing stride length or frequency. Heavier loads can facilitate a more horizontal force application, contributing to improved acceleration. However, compared to NRS, the performance-enhancing benefits of HRS have not been demonstrated. Differences between studies were primarily attributed to the participants’ performance level, training duration, and cycles, and targeted sprint phases (start, acceleration, or maximal speed). We recommend individualizing optimal loads and training volumes based on athlete characteristics and sport-specific demands. Future research should focus on optimizing resistance load based on athletes' initial speed and strength levels, as well as their training cycle phase.

Frequent air travel and the condensed game schedule typical of a National Basketball Association (NBA) team during the season, often results in accompanying sleep disturbances related to sleep length, sleep quality, and sleep timing (with highly harmful impacts on health, both physical and mental). These issues are not only problematic for NBA players, but also the coaches, training staff, and management support. In this narrative review, we summarize the detrimental effects that this travel and game schedule could have on NBA team members' sleep, as well as their physical and mental health. Multiple peer-reviewed articles address the role of sleep in athletic performance and health; however, to date, the literature focused on sleep-related issues that are unique to the NBA schedule is scarce. Firstly, this review addresses the impact of the NBA schedule, outlining the number of games and the travel involved (number of flights, the timing of flights, timings of arrival at destination and hotel); we also outline a typical daily NBA travel schedule, providing the reader a glimpse of what this encompasses. Secondly, we provide a brief overview of sleep science and discuss specific applications related to the NBA. Finally, we provide comment on the unique current situation of the NBA "bubble". Based on this review, there appears to be considerable scope for further investigation of the acute and chronic effects of sleep disturbances concerning the NBA travel and game schedule. Sleep science recommendations need to inform practice, target sleep interventions, and personalized protocols designed to enhance sleep health that can be incorporated at the organizational level.

This review synthesizes contemporary research on nutritional strategies to boost athletic performance, with a special focus on effective macronutrient management, hydration practices, and the crucial roles of micronutrients and specific dietary supplements. It highlights the importance of tailored nutrition plans that meet individual athletic demands, enhance recovery, and improve overall performance. Drawing on the latest scientific insights, this article serves as a comprehensive guide for athletes and sports nutritionists aiming to optimize athletic output and recovery processes. Through the examination of current studies and expert recommendations, we provide actionable insights into developing nutritional protocols that not only support rigorous training schedules but also foster long-term health and performance sustainability. This review aims to bridge the gap between advanced nutritional theory and practical applications for performance enhancement.

Cannabis use has increased, in large part due to decriminalization. Despite this increase in usage, it remains unclear what proportion of athletes use cannabis and what effect it has on athletic performance and recovery. To systematically review cannabis use among athletes, including epidemiology, effect on performance and recovery, and regulations for use in sport. PubMed, MEDLINE, and EMBASE databases were queried from database inception through November 15, 2018. A hand search of policies, official documents, and media reports was performed for relevant information. All studies related to cannabis use in athletes, including impact on athletic performance or recovery, were included. Systematic review. Level 4. Demographic and descriptive data of included studies relating to epidemiology of cannabis use in athletes were extracted and presented in weighted means or percentages where applicable. Overall, 37 studies were included, of which the majority were cross-sectional studies of elite and university athletes. Among 11 studies reporting use among athletes (n = 46,202), approximately 23.4% of respondents reported using cannabis in the past 12 months. Two studies found a negative impact on performance, while another 2 studies found no impact. There was no literature on the influence of cannabis on athletic recovery. Across athletic organizations and leagues, there is considerable variability in acceptable thresholds for urine tetrahydrocannabinol levels (>15 to 150 ng/mL) and penalties for athletes found to be above these accepted thresholds. Overall, these results suggest that approximately 1 in 4 athletes report using cannabis within the past year. Based on the available evidence, cannabis does not appear to positively affect performance, but the literature surrounding this is generally poor. Given the variability in regulation across different sport types and competition levels, as well as the growing number of states legalizing recreational cannabis use, there is a need to improve our understanding of the effects of cannabis use on the athlete and perhaps adopt a clearer and overarching policy for the use of cannabis by athletes in all sports and at all levels.
