Abstract: | Physical exercise is considered an important intervention for promoting well-being and healthy aging.
The objective was to determine the efects of moderate-to-high intensity resistance circuit training on
diferent parameters of body composition, functional autonomy, muscular strength and quality of life in
elderly. A randomized controlled trial was conducted. A total of 45 subjects (27 females, 18 males) aged
between 65–75 years old from Murcia (Spain) were divided by sex, and randomly to experimental group
(n=33, mean age 69±3.2 years old) receiving 12 weeks of moderate-to-high intensity resistance circuit
training and control group (n=33, mean age 70±4.1 years old) receiving no exercise intervention.
Intra-group comparison, the experimental group showed a signifcant increment of lean body mass
in women and men, which also presented a decrease of fat mass. Both sex presented a signifcant
improve in functional autonomy, and signifcately higher values of muscular strength. But no changes
were observed regarding quality of life in these groups. The control group did not show any diferences
pre and post-intervention in women, but in men presented an increment of body mass index and total
weight post-intervention. No changes were showed in the other variables. Similar results were founded
at inter-group comparison. The moderate-to-high intensity resistance circuit training showed increase
in total lean body mass, improvements in functional capacity and signifcantly increase in upper and
lower muscular strength in women and men. Progressive resistance circuit training should be promoted
for the elderly as it has the potential to improve physical performance, thereby prolonging healthy
independent aging. El objetivo fue determinar los efectos del entrenamiento en circuito de resistencia de intensidad moderada-alta sobre diferentes parámetros de composición corporal, autonomía funcional, fuerza muscular y calidad de vida en ancianos. Se realizó un ensayo controlado aleatorizado. Un total de 45 sujetos (27 mujeres, 18 varones) de edades entre 65-75 años de Murcia (España) fueron divididos por sexo, y aleatoriamente al grupo experimental (n = 33, edad media 69 ± 3,2 años) que recibió 12 semanas de entrenamiento en circuito de resistencia de intensidad moderada a alta de intensidad moderada-alta y el grupo de control (n = 33, edad media 70 ± 4,1 años) que no recibió ninguna intervención de ejercicio. En la comparación intragrupo, el grupo experimental mostró un aumento significativo de la masa corporal magra en mujeres y hombres, que también presentaron una disminución de la masa grasa. Ambos sexos presentaron una mejora en la autonomía funcional, y valores significativamente más altos de fuerza muscular. Pero no se observaron cambios en la calidad de vida de estos grupos.El entrenamiento en circuito de resistencia de intensidad moderada-alta mostró aumento en la masa corporal magra total, mejoras en la capacidad funcional y aumento significativo de la fuerza muscular superior e inferior en mujeres y hombres y tiene el potencial de mejorar el rendimiento físico y, por tanto, de prolongar un envejecimiento saludable e independiente. |
