    Introducción: Los hábitos alimentarios y la salud mental son aspectos fundamentales para optimizar la preparación y el rendimiento deportivo de los basquetbolistas. Objetivo: Comparar la frecuencia en el consumo de alimentos y la calidad de vida relacionada con la salud (CVRS) entre basquetbolistas de distinto nivel competitivo (profesional, universitario y amateur). Material y métodos: Estudio transversal que evaluó 122 basquetbolistas masculinos (edad media de 30,60 + 10,79 años), distribuidos en jugadores de básquetbol profesional (JBP; n=25), universitario (JBU; n=26) y amateur (JBA; n=71). Las variables de estudio se evaluaron a través de encuestas en línea referentes a la frecuencia en el consumo de alimentos y CVRS (SF-36). Resultados: Los JBP ostentan un consumo significativamente mayor de cena (F= 5,007; p= 0,020) comparados con los JBU, y de frutas (F= 5,857; p= 0,012), verduras (F= 3,756; p= 0,020) y cena (F= 5,007; p= 0,011) respecto a los JBA. Mientras que los JBU presentan un consumo significativamente mayor de frutas (F= 5,857; p= 0,035) que los JBA. Además, los JBU presentaron un consumo significativamente mayor de bebidas azucaradas (F= 9,293; p= 0,004) respecto a los JBP y JBA. La CVRS no presentó diferencias significativas entre los grupos. Conclusión: Los JBP presentan mayor frecuencia en el consumo de alimentos saludables al compararlos con JBU y JBA. Además, los JBU reportan mayor frecuencia en el consumo de bebidas azucaradas respecto a JBP y JBA. Mientras que, la CVRS es positiva independiente al nivel competitivo de los basquetbolistas.

    Effects of a High-Intensity Interval Training Program on Body Composition and Physical Fitness in Female Field Hockey Players

    High-intensity interval training (HIIT) is zed by achieving similar effects to conventional physical and physiological training in a shorter time, allowing its dissemination in the sports field. The present study was aimed to analyze the effects of a HIIT program on body composition and general and specific physical fitness in Chilean female field hockey players. Experimental, repeated measures, simple blind, parallel groups, and a quantitative approach were used. The participants were randomized, and distributed into a control group (CG; n= 10) that maintained regular field hockey training and an experimental group (EG; n= 10) that also received complementary training with HIIT. Body composition (muscle mass and adipose mass), general physical fitness (jump performance with countermovement jump [CMJ] and maximum oxygen consumption [VO2max] were evaluated with the test Course-Navette), and specific physical fitness (pushing speed, dribbling speed, and shooting accuracy) were assessed with established protocols. Pre- and post-intervention comparisons were made with Student's t and Wilcoxon tests, considering p<0.05. The main results indicate that the EG presented a significant increase in muscle mass (p = 0.024; d = 0.62), CMJ (p = 0.005; d = 1.10), VO2max (p = 0.001; d = 1.58) and a significant reduction in adipose mass (p = 0.023; d = 0.36) and time in pushing speed (p = 0.028; d = 0.79). The CG did not present significant changes in any of the variables analyzed, and no significant differences were reported between the groups. In conclusion, eight weeks of HIIT significantly increases muscle mass, jump performance, and VO2max and significantly reduces adipose mass and time in pushing speed in Chilean female field hockey players.
