    ¿Se deberían replantear las recomendaciones relativas al uso sedentario del tiempo de pantalla en adolescentes?
    (Murcia: Servicio de Publicaciones de la Universidad de Murcia, 2018) Sevil Serrano, Javier; Abós Catalán, Ángel; Aibar Solana, Alberto; Sanz Remacha, María; García-González, Luis
    El objetivo fue analizar el tiempo medio de uso diario de cuatro medios tecnológicos de pantalla (i.e., TV, ordenador, videojuegos y móvil) e identiicar el grado de cumplimiento de las recomendaciones de pantalla, tanto de manera independiente como en su conjunto. Asimismo, se analiza- ron las diferencias en función del tipo de jornada y el género. Participaron 105 estudiantes (M=13.05±0.59)que cumplimentaron un cuestionario refe- rente al tiempo de pantalla de dichos medios tecnológicos. Los adolescentes de esta muestra pasan un tiempo medio de uso diario de 407 minutos de medios tecnológicos de pantalla, siendo la TV el medio más utilizado. Nin- guno de los adolescentes cumple las recomendaciones de tiempo de panta- lla. Asimismo, existe un mayor de tiempo de uso tecnológico los ines de semana y por parte de los chicos. Se discute la necesidad de actualización de las recomendaciones relativas al uso del tiempo de pantalla en adolescentes.

    Weight status Is related to health-related physical fitness and physical activity but not to sedentary behaviour in children
    (MDPI, 2020-06-23) López-Gil, José Francisco ; Brazo-Sayavera, Javier ; Yuste Lucas, Juan Luis; Renato Cavichiolli, Fernando; Expresión Plástica, Musical y Dinámica, ; Actividad Física y Deporte
    Purpose: The aim of this research was to describe, examine, and compare the level of physical fitness, physical activity, and sedentary behaviour in pupils aged 6–13 in the Region of Murcia, Spain, in accordance with weight status. Methods: A total of 370 children (166 girls and 204 boys) aged 6–13 (M = 8.7; DT = 1.8) from the Region of Murcia participated in this descriptive and cross-sectional study. Some anthropometric parameters such as body mass index, waist circumference, as well as skinfold measurements were determined. ALPHA-FIT Test Battery was used to evaluate physical fitness. Krece Plus Short Test was used to measure physical activity level and sedentary behaviour. Results: 52.4% of the children presented excess weight (according to the World Health Organization growth references). Regarding boys, statistically significant differences were found for cardiorespiratory fitness (p < 0.001), relative handgrip strength (p < 0.001), lower muscular strength (p < 0.001), speed-agility (p < 0.001), as well as sport activities hours (p = 0.001) among the three weight status groups (normal weight, overweight, and obesity). As for girls, statistically significant differences were found for cardiorespiratory fitness (p = 0.004), relative handgrip strength (p < 0.001), lower muscular strength (p < 0.001), sport activities hours (p = 0.005), as well as physical activity level (assessed by Krece Plus Test) (p = 0.017). A negative statistically significant correlation was found between body mass index and cardiorespiratory fitness (rho = −0.389), lower muscular strength, (rho = −0.340), and relative handgrip strength (rho = −0.547). At the same time, a positive statistically significant relationship between body mass index and the time spent in speed-agility (rho = 0.263) was shown. Regarding waist circumference and body fat percentage, similar relationships were identified. Moreover, a greater probability of having higher cardiorespiratory fitness (OR = 1.58; CI95% = 1.38–1.82), relative handgrip strength (OR = 1.25; CI95% = 1.19–1.31), more hours of sport activities (OR = 1.40; CI95% = 1.19–1.66), and physical activity level (assessed by Krece Plus Test) (OR = 1.23; CI95% = 1.07–1.42) was noted in the normal weight group. Conclusions: Children that presented normal weight achieved higher results for health-related physical fitness and physical activity than those with excess weight; this was, however, not found to be the case for sedentary behaviour. The authors emphasise the need for changes in public policies and school-based intervention programmes to develop higher levels of both PF and PA in overweight and obese children.
