“…To avoid performance-related issues and recovery challenges due to malnutrition and/or dehydration, as well as electrolyte imbalances, it is essential to design a nutritional plan for each specific phase in an athlete’s career. This plan should consider the varying requirements during competitive periods, training, or off-season, each with its distinct characteristics [ 29 ]. Nutrition in sports is planned, personalized, and periodized, aiming during training to promote recovery and adaptation, achieve optimal body composition, and minimize injuries and illnesses, thereby enabling athletes to train at the highest level.…”

“…For moderate to high intensity exercise (1–3 h per day), the recommended intake increases to 6–10 g/kg/day. Ultra-endurance athletes that have a very high degree of dedication to daily physical activity (4–5 h of exercise at a moderate to high intensity per day) may require a daily intake of 8–12 g per kilogram of body weight [ 29 ]. The International Society of Sports Nutrition (ISSN) suggests that athletes should follow a high carbohydrate (CHO) diet, consuming 8–12 g of carbohydrates per kilogram of body weight per day, in order to optimize their glycogen level [ 134 ].…”

The dietary practices of athletes play a crucial role in shaping their body composition, influencing sports performance, training adaptations, and overall health. However, despite the widely acknowledged significance of dietary intake in athletic success, there exists a gap in our understanding of the intricate relationships between nutrition, body composition, and performance. Furthermore, emerging evidence suggests that many athletes fail to adopt optimal nutritional practices, which can impede their potential achievements. In response, this Special Issue seeks to gather research papers that delve into athletes’ dietary practices and their potential impacts on body composition and sports performance. Additionally, studies focusing on interventions aimed at optimizing dietary habits are encouraged. This paper outlines the key aspects and points that will be developed in the ensuing articles of this Special Issue.

“…Track and field sports can be divided into the strength type, speed type, and endurance type. Different types of sports have slightly different requirements for nutrition [17]. Strength-type athletes have faster protein metabolism and higher excitability of nerves and muscles; therefore, they need to supplement high-protein food.…”

This study aims to understand the influence of nutritional supplementation and sports training on the physical fitness of track and field athletes. Twenty track and field athletes from Chongqing Normal University were supplemented with nutrition and trained for eight weeks. Water, sugar, and vitamins were supplemented. They were trained three times a week, two hours each time. One hour was for special track and field training, and one hour was for physical training. Before and after the experiment, the body composition, sports quality, and functional movement screening (FMS) of the athletes were tested. Compared with before the experiment, the muscle weight of the athletes increased, the fat-free weight increased (p < 0.05), the sports quality significantly improved, the endurance increased, the speed increased, the flexibility improved, the total score of FMS also increased significantly (p < 0.05). Nutritional supplementation and sports training can improve athletes' body composition and sports quality and enhance limb flexibility and stability, which has a positive impact on physical fitness. They can be applied in practical training.

“…El consumo de proteínas como un factor para estimular la síntesis proteica, además del ejercicio hipertrófico, debe generar un balance positivo en la disponibilidad de aminoácidos (Groen et al, 2015), las cantidades a consumir son superiores a las requeridas para compensar la degradación y se relacionan con el esfuerzo de la actividad realizada (Artioli et al, 2019). De base, los deportistas requieren mayores cantidades de proteína que los 0.80 g/kg/d de los no deportistas (Gogojewicz et al, 2020;Grout et al, 2016;Huecker et al, 2019;Jäger et al, 2017;Naderi et al, 2016). Para la mayoría de los deportistas lo recomendado va de 1.40 a 2.00 g/kg/d para construir masa muscular y mantenerla a través de un balance positivo de aminoácidos (Jäger et al, 2017).…”

“…El consumo en exceso de proteínas no se manifiesta negativamente en el corto plazo, el metabolismo proteico se encarga de oxidar los aminoácidos procedentes de las proteínas para formar Urea y cadenas de carbono aprovechables como energía o para almacenarse como grasa (Grout et al, 2016;Naderi et al, 2016;Schoenfeld & Aragon, 2018). No obstante, a largo plazo, debido a la función de los riñones de reabsorción de aminoácidos así como en la excreción de amonio y Urea, han sido estudiados dentro del marco de afección por el consumo excesivo de proteínas, encontrando contraste entre los efectos que van desde positivos a negativos (Huecker et al, 2019;Wu, 2016).…”

Para aumentar la masa muscular, el CrossFit® ha sido relevante a la hora de ofrecer un ejercicio hipertrófico, aunque, el requerimiento proteico a consumir puede transformarse en excesivo. Las funciones renales activadas por la cantidad de metabolitos de degradación de proteínas se han asociado con procesos que desencadenan alteraciones renales. OBJETIVO: Identificar si el perfil de consumo proteico en deportistas de CrossFit® incide sobre la función renal. MATERIAL Y MÉTODO: En un período de cuatro meses, se registró el peso, altura, índice de masa corporal; dieta e información de suplementación proteica de 27 deportistas de CrossFit® voluntarios (23 hombres, 4 mujeres; edad promedio: 28.20 ± 3.60 años) en "Distrito Crossfit" (Jalisco, México). Se solicitaron estudios de Nitrógeno Ureico en Sangre, Urea y Creatinina Sérica, en "Salud Digna" (Jalisco, México), para determinar la tasa de filtración glomerular, con las fórmulas de Cockcroft-Gault, Modification of Diet in Renal Disease-4 y Mawer. Se compararon grupos de consumo alto versus normal por g/kg/d y mayor y menor consumo de 236.00 g/día, considerando la cantidad requerida para aumentar la masa muscular. RESULTADOS: Existieron disminuciones significativas (p<0.050) en la tasa de filtración glomerular con un alto consumo de 236.00 g/día y hubo un aumento significativo (p<0.050) de creatinina sérica en la suplementación durante más de un año, con una ingesta aumentada de 236.00 g/día, en comparación con aquellos con una ingesta adecuada sin suplementación. CONCLUSIÓN: El factor relevante para generar un efecto significativo en la filtración glomerular, es la cantidad y el tiempo de consumo de proteínas. To increase muscle mass, CrossFit® has been relevant in offering hypertrophic exercise, although the protein requirement to be consumed may become excessive. Renal functions activated by the amount of protein degradation metabolites have been associated with processes that trigger renal alterations. OBJECTIVE: To identify whether the protein intake profile in CrossFit® athletes affects renal function. MATERIALS AND METHODS: Over a period of four months, the weight, height, body mass index, diet, and protein supplementation information of 27 volunteer CrossFit® athletes (23 men, 4 women; average age: 28.20 ± 3.60 years) was recorded at "Distrito Crossfit" (Jalisco, México). Blood Urea Nitrogen, Urea, and Serum Creatinine studies were requested at "Salud Digna" (Jalisco, México) to determine glomerular filtration rate, with the Cockcroft-Gault, Modification of Diet in Renal Disease-4 and Mawer formulas. High versus normal intake groups were compared by g/kg/d and a higher and lower intake of 236.00 g/day, considering the amount required to increase muscle mass. RESULTS: There was a significant decrease (p<0.050) in the glomerular filtration rate with high a intake of 236.00 g/day and there was a significant increase (p<0.050) in serum creatinine on supplementation for more than one year with increased intake of 236.00 g/day compared to those with adequate intake without supplementation. CONCLUSION: The relevant factor to generate a significant effect on glomerular filtration is the amount and time of protein intake.
