Estudio comparativo de la duración, intensidad y contexto de las clases de Educación Física impartidas en secundaria por profesores de Educación Física y estudiantes de licenciatura en Actividad Física y Deporte

The objective was to evaluate the duration, intensity and context of physical education classes taught by physical education teachers and undergraduate students in physical activity and sport (LAFD) in public high schools in the municipality of Mexicali, Baja California, Mexico. The system was used as an evaluation instrument to observe the physical activity instruction time (SOFIT), the methodological design was descriptive transversal evaluating 19 physical education classes taught by public secondary teachers and 19 classes taught students of the seventh semester of LAFD. Descriptive statistics were performed to evaluate the variables of duration, intensity and context, the percentages of change (Δ%) of the time of teaching the class and the index of moderate to vigorous physical activity were calculated, resulting in 17% and 91.2% more in the LAFD students than in high school teachers. The equality of the variance was calculated using the t-Student test for independent samples resulting in the physical activity index (p-value = .00) and the duration of the physical education class (p-value = .03), greater than α≤ .05. Based on the results, we can infer according to the evaluations that in the subjects that participated, constructive elements must be provided to increase the time of the physical education class, and in the secondary school teachers to provide feedback on how to teach the class through training with didactic strategies involving the high school student in motor actions of moderate to vigorous intensity at least 50% of the physics class.
