Objetivo: Comparar la composición corporal por antropometría clásica e impedancia bioeléctrica en estudiantado universitario de una universidad peruana. Método: Estudio correlacional, transversal, conformado por 152 estudiantes (77 varones y 75 mujeres) matriculados en el ciclo 2018-II con edad promedio de 20.45 ± 3.63 años. Se calculó para el método de antropometría el índice de masa corporal, mediciones antropométricas y se utilizó la ecuación de Yuhasz (1974) para determinar el porcentaje de grasa corporal, y para el de bioimpedancia eléctrica se utilizó el analizador tetrapolar multifrecuencia de medición segmental directa Inbody 120. Para establecer la correlación se utilizó el coeficiente de Pearson y para la concordancia se utilizó el método gráfico de Bland Altman e índice de estabilidad. Los datos fueron analizados con el programa estadístico IBM SPSS Statistics, versión 27.0. Para todos los análisis se utilizó un nivel de significancia (p<0.05). Resultados: Existe una fuerte correlación estadísticamente significativa (p<0.01y r=0.95) entre los métodos de antropometría y bioimpedancia eléctrica para la determinación del porcentaje de grasa corporal; además, una buena concordancia según el método gráfico de Bland Altman, reforzada con el índice de estabilidad para complemento de la interpretación (IE= 95 %). Conclusiones: Ambos métodos son intercambiables entre sí, por lo que pueden ser usados indistintamente en este tipo de población para determinar el porcentaje de grasa corporal expresado en porcentaje.

Objective: to analyze the morphofunctional profile of Chilean professional soccer players according to their playing position. Method: the study design was non-experimental, with a descriptive-correlational scope. Twenty-nine professional soccer players belonging to the Valdivia Sports Club of Chile were evaluated. Fat percentage was established by measuring four skin folds and applying the Durnin and Womersley equation. For the physical variables, the maximum squat repetition test was applied, and the Brzycki method was used to project the maximum force in one repetition. In explosive force, the Bosco Test was performed; this test evaluates the squat jump (SJ). The level 1 recovery Yoyo Test was used for the aerobic resistance, with heart rate (HR) measurement at the end and in recovery (1 minute). Results: Only significant differences in height are observed between goalkeepers and midfielders (F = 4.491; p = 0.012); this implies that age, weight, and Σ4 folds do not affect in the playing position. Conclusions: it is observed that, in each game position, the players present a different morphofunctional configuration, which allows inferring that the work must be differentiated.

This work has the objective of characterizing the approach to the area of Physical Education in virtuality in elementary and middle schools in the territory of the South American Division of the Adventist educational system in the year 2020. It is a work of quantitative approach, descriptive research and cross-sectional design. The sample consisted of 163 Physical Education teachers at the elementary and middle school levels in Adventist schools in Ecuador, Peru, Bolivia, Uruguay, Paraguay, Argentina, Chile and Colombia. The results highlight the disciplinary adherence of teachers, the use of technological platforms as support for virtual attention and social networks, follow-up of actions, tasks and assignments to students. There is an evaluation process that has become more complex given the virtuality and the conditions of the students, and a good participation in the classes. It is necessary to strengthen the continuous training of teachers and support in the field of teaching methodologies in Physical Education.
