El objetivo del presente estudio fue analizar el efecto a corto plazo de un programa de actividad física alta intensidad (HIIT) sobre la memoria en jóvenes estudiantes. Se trata de un estudio cuantitativo longitudinal con grupo experimental (GE n = 74) y grupo control (GC n = 81). El GE fue sometido a un entrenamiento de 20 minutos de AF de alta intensidad a primera hora de la jornada escolar. Se registraron medidas de memoria a las 8:15 de la mañana (Pre, justo antes del entrenamiento), 9:15 (Post, inmediatamente después del entrenamiento), 10:45 (M3, a las 2 horas), y a las 13,15 (M4, cuatro horas después). La memoria fue medida mediante una prueba ad hoc basada en cartas de la baraja española, donde el participante debía observar con atención 15 cartas mostradas durante 20 segundos y memorizar el mayor número de cartas posible. Para obtener los resultados se empleó ANOVA 2(Grupo) x 4(Tiempo). Los resultados muestran una mejora de la memoria en los adolescentes del grupo experimental (p<0,05). Se obtuvieron diferencias también en función del sexo, y nivel de actividad física semanal de los participantes. Estos resultados sugieren que realizar un programa de actividad física de ala intensidad, a primera hora de la mañana, puede ayudar a mejorar la memoria de los adolescentes
Immediate acute effect of high intensity physical activity in adolescents’ memory. The aim of this study was to analyze the short-term effect of a high intensity physical activity program (HIIT) on memory in young students. It is a longitudinal quantitative study with an experimental group (GE n = 74) and a control group (GC n = 81). The GE underwent a 20-minute high intensity AF training early in the schoo before training), 9:15 (Post, immediately after training), 10:45 (M3, at 2 hours), and at 13, 15 (M4, four hours later). The memory was measured by an ad hoc test based on cards from the Spanish deck, where the participant had to watch carefully 15 cards shown for 20 seconds and memorize as many cards as possible. To obtain the results, ANOVA 2 (Group) x 4 (Time) was used. The results show an improvement of the memory in the adolescents of the experimental group (p<0.05). Differences were also obtained according to the sex, and level of weekly physical activity of the participants. These results suggest that performing a physical activity program of intensity wing, early in the morning, can help improve the memory of adolescents. l day.
