ABSTRACT

SUMMARY: The aim of this study was to determine the effects of High-intensity interval training (HIIT) on the quality of life in healthy young people (YNG) and older adults (OLD)and its correlation with physical health status (anthropometric parameters and lower limb functionality) YNG (21 ? 2 years, BMI 26.37 ? 2.69 n = 12) and OLD (67 ? 5 years, BMI 27.16 ? 3.04 n = 12) groups underwent 12weeks of HIIT. Before and after the HIIT, anthropometric assessments, lower limb functionality tests, and SF-36 quality-of-life questionnaire were performed. There were no significant changes in the SF-36 dimensions (P>0.05). After HIIT, there were improvement percentage changes in Mental Component Summary (MCS) (YNG, +8.51 ? 25.80 % vs. OLD, +2.30 ? 9.05 %) and in Physical Component Summary (PCS) (YNG, +2.66 ? 20.54 % vs. OLD, +4.34 ? 22.71 %). Negative correlations were observed between body mass index (BMI) with PCS (R=-0.570, P=0.009) and with MCS (R=-0.649, P=0.002) in OLD as well as between MCS and waist circumference (R=-0.557, P?0.001) in both groups. Also, correlations were observed between PCS and the sit-to-stand test (R=-0.424, P=0.006) in both groups and gait speed (R=0.458, P=0.042) only in YNG. HIIT promotes positive percentage changes in quality of life, with YNG showing better results in PCS and OLD in MCS. Quality of life and physical health status were correlated in both groups.


RESUMEN: Determinar los efectos del entrenamiento interválico de alta intensidad (HIIT) sobre la calidad de vida en jóvenes sanos (YNG) y personas mayores (OLD) y su correlación con el estado de salud física (parámetros antropométricos y funcionalidad de miembros inferiores). Ambos grupos, YNG (21 ? 2 años, IMC 26,37 ? 2,69 n = 12) y OLD (67 ? 5 años, IMC 27,16 ? 3,04 n = 12) realizaron 12 semanas de HIIT. Antes y después del HIIT, se realizaron evaluaciones antropométricas, pruebas de funcionalidad de miembros inferiores y cuestionario de calidad de vida SF-36. No hubo cambios significativos en las dimensiones del SF-36 (P >0,05). Después del HIIT, hubo cambios porcentuales de mejora en el componente sumario mental (MCS) (YNG, +8.51 ? 25.80 % vs. OLD, +2.30 ? 9.05 %) y el componente sumario física (PCS) (YNG, +2,66 ? 20,54 % vs. OLD, +2,30 ? 9,05 %), correspondientes a la calidad de vida. Se observaron correlaciones negativas entre el índice de masa corporal (IMC) con PCS (R=-0,570; P=0,009) y con MCS (R=0,649; P=0,002) en OLD, así como entre MCS y circunferencia de cintura (R = - 0,557, P?0,001) en ambos grupos. Además, se observaron correlaciones entre PCS y la prueba de sentarse y levantarse (R = -0,424; P = 0,006) en ambos grupos y la velocidad de la marcha (R = 0,458; P = 0,042) solo en YNG. HIIT promueve cambios porcentuales positivos en la calidad de vida, con YNG mostrando mejores resultados en PCS y OLD en MCS. La calidad de vida y el estado de salud física se correlacionaron en ambos grupos.
