Efectos de desentrenamiento de 16 semanas sobre la fuerza muscular, flexibilidad y autonomía funcional de mujeres mayores, después de un programa de ejercicios

Abstract

The present investigation evaluated the effects of 16 weeks of detraining on muscular force, flexibility and functional autonomy in older women after an exercise program. 10 women were analyzed, aged 61.2±6.7 years and weighing 65.6±14.4 kg. The one-repetition maximum (1RM) test was used to evaluate strength; the sit and reach test was used for flexibility, and the GDLAM protocol was used for functional autonomy. The Student t and Wilcoxon tests were used. After 16 weeks of detraining, strength in the low rowing (∆% = -20.1%; p=0.01) and dorsal traction exercises (∆% = -16.1%; p=0.01) showed a statistically significant decrease. The other exercises, biceps (∆% = -8.3%), triceps (∆% = -9.2%) and pectoral (∆% = -13%), did not decrease. Functional autonomy LPDV (∆%= -11.7%), LPS (∆%= -5.2%), C10m (∆%= 0.7%) and LCLC (∆%= 3.1%), as well as the GDLAM index (IG) (Δ% = -3.06%; p = 0.35) did not decrease either in the detraining period. Flexibility did not show a statistically significant decrease (Δ% = 6.05%; p = 0.67). The study showed that, after 16 weeks of detraining, strength, functional autonomy and flexibility did not evidence statistically significant decreases.
