Previous issue date: 2009-05-15 / Changes introduced by cardiopulmonar and neuromuscular training on basal serum insulin-like grow factor-1 (IGF-1) and cortisol levels, functional autonomy and quality of life in elderly women The aim of this study was to compare the effects of strength and aerobic training on basal serum IGF-1 and Cortisol levels, functional autonomy (FA) and quality of life (QoL) in elderly women after 12 weeks of training. The subjects were submitted the strength training (75-85% 1-RM) with weight exercises (SG; n=12; age=66.08 ? 3,37 years; BMI=26,77 ? 3,72 kg/m2), aerobic training with aquatic
exercises (AG; n=13; age=68,69 ? 4,70 years; BMI=29,19 ? 2,96 kg/m2) and control group (CG; n=10; age=68,80 ? 5,41 years; BMI=29,70 ? 2,82 kg/m2). Fasting blood was analyzed to measure basal IGF-1 and cortisol levels by
chemiluminescence method. The t-Student test showed increased IGF-1 in the SG (p<0.05) for intragroup comparison. The Repeated-measure ANOVA presented increased IGF-1 (p<0.05) in the SG compared to the other two groups. There were no differences in cortisol levels. All the FA tests (GDLAM autonomy protocol) presented decreased significant in the time marked in seconds to the
SG. The same results were found in the AG, except in the rise from a sitting position test. The autonomy index presented significant improvements (p<0.05) in
the SG related to the AG and CG and in the AG to the CG. The SG showed increased QoL (p<0.05) (by WHOQOL-Old questionnaire) in the facet 1 (sensorial functioning) and facet 5 (death and dying). Thus, the SG obtained
positive changes on IGF-1 and FA levels when compared to the AG. This suggests that strength training can indicated to decrease the effects of ageing. / O objetivo do estudo foi comparar os efeitos dos treinamentos de for?a e ?bico sobre os n?veis s?ricos basais de IGF-1 e Cortisol, autonomia funcional (AF) e qualidade de vida (QV) em mulheres idosas ap?s 12 semanas de treinamento. Os sujeitos foram submetidos a um treinamento de for?a (75-85% 1-RM) na muscula??o (GF; n=12; idade=66,08 ? 3,37 anos; IMC=26,77 ? 3,72
kg/m2), treinamento aer?bico na hidrogin?stica (GA; n=13; idade=68,69 ? 4,70 anos; IMC=29,19 ? 2,96 kg/m2) e um grupo controle (GC; n=10; idade=68,80 ?
5,41 anos; IMC=29,70 ? 2,82 kg/m2). A coletada de sangue foi feita em jejum para as an?lises dos n?veis de IGF-1 e Cortisol basal (M?todo Quimioluminesc?ncia). O teste t-Student mostrou aumento do IGF-1 no GF (p<0,05) na compara??o intragrupo. A ANOVA de medidas repetidas apresentou eleva??o do IGF-1 (p<0,05) no GF comparado aos demais grupos. Os n?veis de cortisol n?o apresentaram diferen?as. Todos os testes de AF (protocolo de autonomia GDLAM) apresentaram redu??es significativas nos tempos aferidos em segundos para o GF. Os mesmos resultados foram encontrados para o GA,
exceto no teste levantar da posi??o sentada. O ?ndice de autonomia apresentou melhoras significativas (p<0,05) do GF para o GA e GC e do GA para o GC. O GF apresentou aumentos significativos (p<0,05) na QV (question?rio WHOQOLOld) nas facetas 1 (habilidade sens?rio) e 5 (morte e morrer). Assim, o GF obteve melhoras significativas nos n?veis de IGF-1 e de AF quando comparado ao GA. Isto sugere que o treinamento de for?a pode ser indicado para minimizar os efeitos delet?rios do envelhecimento
