Impactos del aislamiento social en la actividad física y la imagen corporal evidencias de estudiantes universitarios durante la pandemia de Covid-19
(Centro Universitário Estácio de Ourinhos, 2026) Missias Moreira, Ramon; Mota, Jorge; Castro Lemus, Nuria; Motricidad Humana y Rendimiento Deportivo; SEJ596: Feminism, Entrepreneurship and Innovation in Exercise
La pandemia de COVID-19 provocó cambios significativos en las rutinas cotidianas, afectando especialmente la salud física y mental de los estudiantes universitarios. En este contexto, el presente estudio tuvo como objetivo analizar el impacto del aislamiento social en la práctica de actividad física y en la percepción de la imagen corporal entre estudiantes universitarios de Educación Física. Se realizó un estudio observacional de corte transversal con enfoque metodológico mixto, con predominio cualitativo, en el que participaron 65 estudiantes de una universidad pública brasileña. La recolección de datos se llevó a cabo mediante cuestionarios en línea que incluyeron variables biosociodemográficas, clínicas y percepciones subjetivas relacionadas con la actividad física durante el período de confinamiento. Los datos fueron analizados mediante estadística descriptiva y análisis de contenido según Bardin (2011). Los resultados evidenciaron una reducción significativa en los niveles de actividad física y un aumento del comportamiento sedentario, reportado por el 53,85% de los participantes. Asimismo, se observó una prevalencia de sobrepeso y obesidad del 46,16% y alteraciones en la calidad del sueño en el 30,78% de los estudiantes. Los relatos cualitativos destacaron tanto las dificultades impuestas por el aislamiento como la resignificación de la actividad física como estrategia de autocuidado y bienestar. Se concluye que el aislamiento social intensificó el sedentarismo y las preocupaciones relacionadas con la imagen corporal, aunque también evidenció estrategias adaptativas de los estudiantes para mantener prácticas corporales orientadas al bienestar.
Editorial: Dietary supplements and ergogenic aids in relation to health and performance
(Frontiers Media S.A., 2024) Forbes, Scott C.; Best, Russ; Domínguez Herrera, Raúl; Motricidad Humana y Rendimiento Deportivo
Dietary supplements and ergogenic aids are used to enhance exercise performance and health. When deciding to use dietary supplements or ergogenic aids, one must use an evidence-based approach. Further, it is important to examine the safety and efficacy of these dietary supplements under specific populations or to evaluate the interaction effects with other ingredients. Therefore, we created a special issue entitled “Dietary supplements and ergogenic aids in relation to health and performance”, which attracted several global experts in exercise nutrition. Specifically, the special issue attracted 6 high quality original manuscripts. In this editorial, we will briefly highlight key points of each manuscript.

Misogyny and cultural impoverishment: the educational effects of symbolic violence against women in sports media
(Universidade Estadual de Maringá (UEM), 2026) Bianchi, Paula; Moya Mata, Irene; Altmann, Helena; Cabeza Ruiz, Ruth; Motricidad Humana y Rendimiento Deportivo; HUM1097: FEMINAE: Feminismo, Educación, Motricidad e Investigación
Los medios de comunicación no solo informan, sino que también educan moldeando imaginarios sociales que influyen en la construcción de identidades, aspiraciones y referentes, especialmente en la infancia y adolescencia. Sin embargo, incluso con el aumento de la participación de las mujeres en actividades deportivas en todos los niveles, las deportistas siguen estando escasamente representadas en la prensa escrita. El presente artículo analiza la representación del deporte femenino en dos diarios deportivos españoles (Marca y Diario AS) durante el primer trimestre de 2025, con el objetivo de identificar las formas de violencia simbólica asociadas al tratamiento mediático de las deportistas. A través de una metodología mixta, se analizaron 60 portadas y 415 titulares. La presencia del deporte femenino se observó únicamente en el 37% del material analizado. El número de titulares relacionados con las deportistas fue aún menor, representando solo el 7%. Además de la escasa presencia, las narrativas textuales y visuales refuerzan estereotipos sexistas y formas de violencia simbólica. Se destaca la necesidad de incluir la alfabetización mediática con perspectiva feminista en la formación docente y en la Educación Física escolar con el fin de educar para el desarrollo una mirada crítica ante estos discursos, promoviendo una cultura deportiva más equitativa

Could the Hybridization of the SE/TGfU Pedagogical Models Be an Alternative for Learning Sports and Promoting Health? School Context Study
(MDPI, 2023) López Lemus, Ismael; Del Villar, Fernando; Rodríguez Gutiérrez, Amparo; González Silva, Jara; Moreno, Alberto; Motricidad Humana y Rendimiento Deportivo
The present study aims to analyze the influence of the Sport Education (SE)/Teaching for understanding (TGfU) hybrid unit on enjoyment, perceived competence, intention to be physically active, skill execution, decision making, performance and game involvement. A short-term (12-lesson) pre-test/post-test quasi-experimental design was conducted in two groups: control (technical approach: 70 students; age = 14.43 ± 0.693; n = 32 female) and experimental (hybrid unit SE–TGfU: 67 students; age = 13.91 ± 0.900; n = 30 female). The coding instrument was based on the Game performance Assessment Instrument. The Enjoyment and Perceived Competence Scale and the Measure of Intentionality to be Physically Active questionnaire were also used. The results of pairwise comparisons between the groups showed higher post-test scores for most dependent variables for boys and girls using the hybrid SE/TGfU unit. Lower post-test scores were found in pairwise comparisons for several dependent variables in both boys and girls. The present study showed that the application of hybrid models SE/TGfU could increase and help facilitate students’ game involvement and game performance, enjoyment, perceived competence and intention to be physically active, in both boys and girls. In future studies, it would be necessary to analyze psychological variables in the educational context for a deeper assessment.

(Taylor & Francis, 2026) Pecellín Marchena, Roberto C.; Biagiotti, Gilda; Sanz Martinez, Patricia; Pérez López, Aurora Virginia; Motricidad Humana y Rendimiento Deportivo; Contabilidad y Economía Financiera; Didáctica y Organización Educativa; HUM1097: FEMINAE: Feminismo, Educación, Motricidad e Investigación; SEJ472: Nuevas Tendencias de Investigación en Auditoria y Sistema de Información Contable; HUM423: I.D.E.A (Innovación, Desarrollo, Evaluación y Asesoramiento)
This study explores the experiences of Spanish graduates with disabilities who successfully completed a university degree in the field of Social Sciences. The research employed a qualitative methodology, using individual semi-structured interviews to explore factors that contributed to the university success of 32 graduates with disabilities. The information was analysed through an inductive system of categories and codes. The findings are presented in three main areas that highlight self-efficacy as a key factor for university success: personal characteristics that acted as facilitators, coping strategies for learning difficulties, and actions to build relationships within the university community to overcome obstacles. The study concludes that self-efficacy is an ability that helps people with disabilities to overcome barriers and achieve university success
Acute Nitrate Supplementation Affects Transition Points in Progressive Incremental Testing?
(Universidad Nacional Costa Rica. UNA, 2025) Dias dos Santos Leal, Ludmila; de Abreu, Wilson César; Gonçalves, Reginaldo; Domínguez Herrera, Raúl; Fernandes da Silva, Sandro; Motricidad Humana y Rendimiento Deportivo
Introduction: Nitrate supplementation has shown promising results in endurance sports. Objective: This study aims to use heart rate (HR) and its derivatives—the heart rate inflection point (HRIP) and heart rate deflection point (HRDP)—to detect metabolic transition points (MTPs) and peak velocity (Vpeak) in amateur runners after acute nitrate (NO3-) supple-mentation with sugar beet juice. Methodology: We administered 70 ml of concentrated beet juice rich in NO-3 (~6.4 mmol NO3- - 400 mg) or a NO-3 depleted placebo (0.04 mmol NO-3 >0.8 g/L) to thirteen male amateur athletes two hours before they underwent progressive incremental testing (PIT) on a treadmill until exhaustion, with a 7-day washout period. We plotted HR data every 2 minutes to identify HRIP and HRDP, and subjects needed to reach at least 90% of their HRMÁX for the test to be considered maximal. We calculated Vpeak using Kuipers’ formula and set the threshold for statistical signifi-cance at p<0.05. Results: HRMAX values after supplementation with either placebo or beet juice did not differ significantly (p=0.573). Similarly, MTP data, including HRIP (p=0.252) and HRDP values (p=0.508), showed no significant differences after supplementation. No differences were observed in Vpeak or the velocities at HRIP and HRDP post-supplementation (p=0.562; p=0.340, respectively). Conclusions: Nitrate supplementation did not enhance performance as evidenced by HRMAX, HRIP, HRDP, and Vpeak metrics remaining unchanged post-supplementation.
Brecha de género en nutrición deportiva. Un camino todavía por recorrer
(Academia Española de Nutrición y Dietética, 2024) Domínguez Herrera, Raúl; Pérez López, Alberto; Pérez Esteve, Edgar; Pérez Armijo, Patricio; Bonilla, Diego A.; Kammar García, Ashuin; Troncoso Pantoja, Claudia; Fernández Villa, Tania; Apolinar Jiménez, Evelia; Gamero, Amparo; Lozano Lorca, Macarena; Amendra Pegueros, Rafael; Motricidad Humana y Rendimiento Deportivo
La década de 1960 marcó un cambio clave en el deporte gracias a su profesionalización y al avance de las Ciencias del Deporte, destacando los estudios escandinavos sobre la relación entre glucógeno, dieta y fatiga, lo que sentó las bases de la nutrición deportiva. Estos descubrimientos influyeron en recomendacio-nes dietéticas para atletas, como el consumo de carbohidra-tos, que coincidieron con hitos como la ruptura del récord de maratón en 1967. Hoy, la nutrición deportiva es esencial en el rendimiento de las y los atletas, con organismos como el Co-mité Olímpico Internacional, el Colegio Americano de Medicina del Deporte o la Sociedad Internacional del Nutrición Deportiva, quienes han establecido pautas basadas en evidencia, y con ello el rol clave del dietista-nutricionista se ha consolidado en equi-pos deportivos de alto nivel.
Sports Supplement Use in Road Cycling: A Comparative Analysis by Sex and Competitive Category †
(MDPI, 2025) García Durán, Jesús; Romero García, David; Martínez Sanz, José Miguel; González Jurado, José Antonio; Sánchez Oliver, Antonio Jesús; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
This study analyzes and compares sports supplement (SS) consumption among federated road cyclists, considering sex and competition category. The aim is to identify key factors influencing SS use and provide insights for developing nutritional strategies in cycling. A cross-sectional, descriptive study was conducted, involving 1503 cyclists (1231 men and 272 women). Data were collected through a validated questionnaire assessing anthropometric data, training habits, SS consumption patterns, and sources of information. Results indicate that 64.3% of cyclists currently use SS. Women reported a significantly higher consumption rate (88.2%) compared to men (59.1%), although men had a higher average SS intake than women (8.28 ± 9.36 vs. 6.76 ± 5.96). Additionally, SS use decreased with age and competition level, with elite cyclists showing the highest prevalence (76.3%) and master 50 the lowest (58.4%). Group A supplements (scientifically supported) were the most frequently used, while Group C supplements (limited evidence) and Group D substances (prohibited) were more commonly consumed by men. Findings highlight significant differences in SS consumption based on sex and competition level, with elite cyclists and women reporting higher prevalence. However, men reported a higher average number of SS consumed. The study underscores the need for targeted nutritional education, particularly among master cyclists, to promote evidence-based SS use and minimize the risks of ineffective or unsafe supplementation. Future research should explore the long-term effects of SS consumption in cycling and the effectiveness of educational interventions for safe and optimized supplementation practices.
Sport supplementation in competitive swimmers: a systematic review with meta-analysis
(BMC, 2025) Domínguez Herrera, Raúl; López León, Inmaculada; Moreno Lara, Javier; Rico, Esteban; Sánchez Oliver, Antonio Jesús; Sánchez Gómez, Angela; Pecci Barea, Francisco Javier; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
Background:Competitive swimmers have a high prevalence of sports supplement (SS) consumption. However, only a few SS are scientifically proven to be safe, effective, and legal. Therefore, before incorporating supplements to enhance performance and health in competitive swimming, it is crucial to conduct an analysis and review to assess their effects. The objective of this study was to analyze the demonstrated effects of SS, as reported in published studies, on the swimming performance of competitive swimmers. Methods:Following PRISMA guidelines, a systematic search was conducted across six databases for the selection of studies included in this review. Studies that analyzed the effects of sports supplementation compared to placebo were included and subjected to meta-analysis. Results:This revision included 23 studies, 16 of them (69.6%) qualified as excellent and 7 (30.4%) as good at the methodological level based on the punctuation in the PEDro scale. The systematic review included 422 swimmers (61.8% male, 38.2% female), with distances assessed ranging from 50 m to 800 m, including studies employing interval procedures. Creatine showed a significant effect (ES = −0.46; 95% CIs = −0.75 to −0.17, p = 0.002; I2 = 11%) on swimming performance, while the rest of the analyzed supplements did not show significant effects (all p > 0.05). Conclusions:Creatine supplementation demonstrated ergogenic benefits for competitive swimmers, although the evidence supporting the use of this supplement is still limited. Sodium bicarbonate and β-alanine may enhance performance in distances with higher glycolytic demands, while caffeine is effective at dosages of 3–6 mg/kg administered 60 min before exercise. Further research is needed to confirm the potential ergogenic effects of other supplements, such as beetroot juice.

(Nature Publishing Group, 2025) Montalvo Alonso, Juan Jesús; Val Manzano, Marta del; Ferragut, Carmen; Valadés, David; López Samanes, Álvaro; Domínguez Herrera, Raúl; Pérez López, Alberto; Motricidad Humana y Rendimiento Deportivo
To examine the single and combined effect of acute beetroot juice and caffeine supplementation in muscular strength, power, and endurance performance. Thirteen resistance-trained males participated in a triple-blind, cross-over, randomized controlled-trial with four conditions: (a) caffeine (CAF); (b) beetroot juice (BJ); (c) caffeine and beetroot juice (CAF + BJ); (d) placebo (PLA). Participants ingested 70 mL of beetroot juice, concentrated NO3−-rich beverage (BJ, 6.4 mmol NO3−) or PLA (~ 0.04 mmol NO3−) 180 min and caffeine or placebo (3 mg/kg) 60 min before the trial. Muscular strength/power was evaluated at 25%, 50%, 75%, 90% and 100%1RM and muscular endurance at 65%1RM, in bench press (BP) and back squat (BS). In all tests, mean (Vmean and Wmean) and peak (Vpeak and Wpeak) velocity and power output were measured. In BS, muscular strength/power showed a supplement-by-load effect in Vmean and Wmean (P < 0.05, ηp2 = 0.167–0.173), with caffeine increased compared to placebo at 75%, 90% and 100%1RM (9–25%, P < 0.005, g = 0.51–1.47); while in muscular endurance, significant differences were found in number of repetitions, Vmean and Wmean (P < 0.05, ηp2 > 0.277), in all experimental groups (CAF, BJ and CAF + BJ) compared to placebo (6–17%, P < 0.05, g = 0.46–94). No differences in muscular strength/power or endurance were found in BP. Single and combined acute beetroot juice and caffeine intake increased muscular endurance performance at 65%1RM in back squat but not in bench press exercise.
Perceived neighborhood assets and anthropometric indicators in schoolchildren living in high-risk urban areas
(Universidade Federal de Santa Catarina (UFSC), 2026) Castro Lemus, Nuria; Mendoza Lobo, Karen Lizeth; Coll Costa, Jorge de Lázaro; Márquez López, Esperanza; Motricidad Humana y Rendimiento Deportivo; SEJ596: Feminism, Entrepreneurship and Innovation in Exercise
This study examined the association between perceived neighborhood assets and anthropometric markers in schoolchildren living in urban areas at high social risk, comparing findings for arm span with those observed for body mass index (BMI). A cross-sectional study was conducted with 164 schoolchildren (82 girls and 82 boys; aged 6-15 years) from Tegucigalpa, Honduras. An adapted neighborhood assets scale was administered, and its internal structure was evaluated through exploratory factor analysis. The association between perceived community capital and arm span was estimated using hierarchical linear regression while adjusting for age and sex. BMI was examined as a comparative weight-related indicator. Factor analysis identified a three-factor structure with high internal consistency (α = 0.837-0.943). Sex comparisons showed no differences in age, BMI, or arm span, although community capital scores were higher among girls (p = 0.035). In the adjusted model, community capital was positively associated with arm span (β = 0.155; p = 0.004), increasing the explained variance by 2.2%. No significant associations were observed between community capital and BMI. These findings suggest that among schoolchildren living in socially adverse urban contexts, perceived community capital may be associated with a structural marker of physical growth but not with a weight-related indicator. Longitudinal studies are required to clarify the temporal nature and direction of these associations

(MDPI, 2025) Puchalt Urbano, Xavier; Calderón García, Andrea; Jesús R. Huertas; Sánchez Oliver, Antonio Jesús; López de la Torre, Cristina; Águila Aguilar, Elena; López Soto, Pablo Jesús; Luque, Raúl M.; Mata Ordóñez, Fernando; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
Field hockey is a high-intensity intermittent sport, where nutrition and sleep play an important role in the performance and health of all players, especially in women, who often exhibit a dietary pattern characterized by low energy and carbohydrate intake, along with poor nighttime habits. The purpose of this study is to evaluate the profile of female field hockey players by analyzing their energy and macronutrient intake, prevalence of LEA risk, use of SS, and sleep characteristics. Methods: A cross-sectional, observational, and descriptive study was carried out with 75 female players. Validated questionnaires were used to determine general sports nutrition knowledge (NUKYA) and specific knowledge of carbohydrates in sports (CEAC-Q), sleep quality (ASSQ), low energy availability risk (LEAF-Q), and use of sport supplements. In addition, a 7-day dietary record was analyzed. Results: Players showed a high general nutrition knowledge (NUKYA mean: 66.0 ± 8.5 points; 68.0% scored high), but a pronounced deficiency in specific carbohydrate knowledge (CEAC-Q mean: 24.3 ± 14.9 points; 84.0% scored low). Dietary intake analysis revealed significant deficiencies: mean energy intake was 31.9 ± 10.8 kcal/kg/day, resulting in insufficient intake for 78.7% of players. Carbohydrate intake was particularly low (3.6 ± 1.5 g/kg/day), with 86.7% failing to meet recommendations. Furthermore, 33.3% of players were at risk of Low Energy Availability (LEA). LEA risk (LEAF-Q score) was negatively correlated with both protein (r = −0.363; p = 0.001) and carbohydrate intake (r = −0.347; p = 0.003). Regarding sleep, the mean disturbance score (SDS) was 6.5 ± 2.9 (mild disturbance), with 33.3% showing moderate–severe disturbance, and 92.0% sleeping ≤8 h. Finally, 78.7% of players used supplements, with usage correlated with CEAC-Q scores (r = 0.233; p = 0.044), and 86.4% were guided by non-professional sources. Conclusions: Female hockey players do not meet dietary recommendations for energy and carbohydrates and exhibit a high prevalence of low energy availability and sleep disturbances, despite having acceptable general sports nutrition knowledge. It is recommended to implement specific educational and nutritional strategies to enhance the knowledge, performance, and health of female hockey players.
Effects of Low Load Blood Flow Restriction Training on Post-Surgical Musculoskeletal Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
(MDPI, 2025) Santos Pérez, Diego; Ochiana, Nicolae; Carrasco Páez, Luis; Martínez Díaz, Inmaculada C.; Motricidad Humana y Rendimiento Deportivo; Educación Física y Deporte; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
Low-Load Blood Flow Restriction Training (LLBFRT) is an emerging approach in order to increase muscle endurance and muscle volume, as well as decrease pain in the early rehabilitation phase. The purpose of this review was to analyze the published literature on the effects of this intervention on musculoskeletal postsurgical rehabilitation. Methods: Six electronic databases (Cochrane Library, PubMed, SPORTDiscus, SCOPUS, CINAHL, and Web of Science) were searched from 2004 to 2024. Articles including adults who underwent any type of musculoskeletal surgery were screened. The Risk of Bias and Quality of Evidence were assessed using the Cochrane Risk-of-Bias Tool (RoB 2) and GRADE-CERQual scale. A meta-analysis was performed on the identified studies using RevMan version 5.4. The analysis model was synthesized as a random effects model, and the standard mean difference (SMD) was used as the effect measure. Results: Thirteen articles fulfilled the selection criteria and were included in this review. Muscle strength, muscle volume, and perceived pain had positive results in almost all studies; however, the meta-analysis reported a lack of overall effect in favor of LLLBFRT vs. control interventions in both lower and upper limb evaluations. Conclusions: Although some studies indicate positive effects of LLBFRT on strength, muscle size, and pain perception in operated lower and upper limbs, these results must be interpreted carefully since the overall effects are unclear. Nonetheless, the selected studies did not report discomfort claims; therefore, the LLBFRT could be a safe recovery strategy to use when rehabilitation programs need to gain variety.

Resultados: La experiencia generó niveles elevados de implicación y participación sostenida. Emergieron cuatro dimensiones principales: conciencia corporal, expresión emocional, construcción identitaria e interacción social y alfabetización digital. Los perfiles más activos mostraron narrativas complejas, creatividad y uso significativo del entorno digital. Conclusiones: Instagram actuó como espacio pedagógico de producción simbólica, comunidad de aprendizaje y extensión virtual de contenidos propios de la Expresión Corporal. Instagram puede constituir un recurso pedagógico útil en la formación inicial del profesorado de Educación Física cuando se incorpora mediante diseños didácticos sólidos, favoreciendo nuevas formas de aprendizaje expresivo, relacional y reflexivo.
Effects of an innovative educational program on female athletes’ knowledge and habits related to pelvic floor care: a quasi-experimental study
(Frontiers Media, 2025) Vico Moreno, Elena; Bosch Donate, Elisa; Fernández Domínguez, Juan Carlos; Sastre Munar, Andreu; Bachero Mena, Beatriz; Romero Franco, Natalia; Motricidad Humana y Rendimiento Deportivo
The physical demands of sports require female athletes to be aware of pelvic floor (PF) care. However, knowledge about PF dysfunctions and unhealthy habits remains insufficient in sports populations. Innovative and specific educational strategies are needed to engage female athletes. This study evaluated the effects of an online educational program on PF knowledge and care habits in female athletes. A three-session online program with practical content and 3D models was implemented. Of the 130 registered athletes (35.9 ± 11.2 years old), 70 fully attended (FA), 23 partially attended (PA), and 37 did not attend (NA). Before and 4 weeks after the program, participants completed a questionnaire assessing: (1) demographics and sports data; (2) PF symptomatology; (3) knowledge of urinary incontinence (UI), female sexual dysfunction (FSD), ano-rectal incontinence (ARI), and pelvic organ prolapse (POP); and (4) habits during micturition, defecation, and sports practice. FA and PA athletes rated the utility of the program (0–10 scale). After the program, FA athletes showed improved knowledge of UI (p = 0.032), FSD, ARI, and POP (ps < 0.001) compared to baseline and NA athletes (ps < 0.001). FA athletes also reduced unhealthy habits during micturition (p = 0.003) and defecation (p = 0.003), and had fewer unhealthy habits overall compared to NA athletes. The utility of the program was rated 8.4 points. A three-session innovative online educational program proved effective in enhancing PF-related knowledge and improving care habits among female athletes.
Consensus Document of the Spanish Nutrition Society (SEÑ) on Nutritional Strategies in Sports
(MDPI (Multidisciplinary Digital Publishing Institute), 2025) Mielgo Ayuso, Juan; Macho González, Adrián; Úbeda, Natalia; Sánchez Oliver, Antonio Jesús; Martínez Ferrán, María; Fernández Lázaro, Diego; Aparicio Ugarriza, Raquel; Roche, Enrique; González Gross, Marcela; Motricidad Humana y Rendimiento Deportivo; CTS972: Análisis Biológico y Funcional del Ejercicio Físico
Nutrition plays a fundamental role in sports performance by influencing energy availability, recovery, and training adaptation. In recent years, different dietary strategies have gained popularity among athletes, although the evidence supporting their efficacy is inconsistent. Objective: This consensus document, developed under the auspices of the Spanish Society of Nutrition, aims to provide a critical overview of the most relevant nutritional strategies currently used in sports and to offer evidence-based practical recommendations for both professional and recreational athletes, coaches, and health professionals. Methods: A narrative review was conducted following standardized scientific procedures by a multidisciplinary panel of experts. The analyzed strategies included high-carbohydrate, low-carbohydrate, ketogenic, intermittent fasting, plant-based, Paleolithic, and carbohydrate periodization diets. Each strategy was assessed based on its physiological rationale, evidence of performance in endurance, strength/power, sprint, aesthetic, weight category, and team sports, practical applications, and potential risks. Results: The available evidence shows that no single dietary strategy can be universally recommended for all athletes. High carbohydrate availability remains the most consistent approach for sustaining performance in endurance and high-intensity efforts. Low-carbohydrate and ketogenic diets enhance fat oxidation but often compromise exercise economy at competitive intensity levels. Intermittent fasting may improve body composition and metabolic health; however, it requires careful adaptation. Well-planned plant-based diets can support performance, although attention to certain nutrients (e.g., B12, iron, and omega-3) is essential. Paleolithic diets improve metabolic parameters but show limited direct evidence of athletic performance. Carbohydrate periodization is a promising tool for combining metabolic adaptations with competitive demands. Conclusions: Nutritional strategies should be individualized according to the athlete’s sport, training phase, and personal context. Professional guidance is crucial for minimizing risks and optimizing benefits. Further well-designed, long-term studies on athletes are needed to resolve the current controversies.
