Resumen

Se registró la frecuencia cardiaca de 182 estudiantes (97 chicos y 85 chicas) de entre 12 y 18 años durante sus clases de Educación Física. Los resultados muestran una media del 21,62±14,33% del tiempo de clase en valores MVPA (moderate to vigorous physical activity). Respecto al género, pese a no ser significativo, los mayores valores corresponden a la chicas (23,47±14,45% vs 19,99±14,10%; p=0,106). No se ha observado efecto del tipo de sesión (deportes colectivos, deportes individuales, juegos tradicionales o bailes) sobre el tiempo en valores MVPA (p>0,05; TE<0,020), obteniéndose los mayores valores en sesiones de deportes colectivos. Los resultados muestran que la intensidad y duración de las clases registradas no cumplen con las recomendaciones para suponer un adecuado trabajo cardiovascular.

PALABRAS CLAVE: Frecuencia cardiaca, niveles de actividad física, educación secundaria, MVPA, IMC.

 

 

ABSTRACT:

 Heart rate from 182 students (97 boys and 85 girls) aged between 12 and 18 years was assessed during physical education classes. Results have shown an average time of 21.62±14.33% of lesson time in MVPA (moderate to vigorous physical activity). Though there was no significant gender difference, girls were more active (23.47±14.45% vs 19.99±14.10%). There was no significant effect of session type (team sports, individual sports, traditional games or dancing) on time spent at MVPA values (p>0.05; ES<0.020), obtaining the highest values in team sports sessions. Results show that intensity and duration of analyzed classes do not comply with recommendations to become an adequate cardiovascular exercise.

KEYWORDS: Heart rate, physical activity levels, Secondary Education, MVPA, BMI.
