Previous issue date: 2012-12-12 / Physiological changes induced by the aging process is dynamic and progressive, reducing the adaptability and independence of older people and may be influenced by genetic and environmental factors. Thus the aim of this thesis was to investigate the association between polymorphism of the ACE gene ID and the phenotypes of muscular strength and blood pressure of 62 elderly Brazilian (67.35 ? 5.66 years) during a 16-week program of supervised training. The elderly women were stratified by age, with the group 1 (G1, n = 34) <70 years and group 2 (G2 n = 28) ≥ 70 years, and in three groups by ACE, ACE-II (n = 8) ACE- DD (n = 35) and ACE-ID (n = 19). The level of muscle strength was evaluated by the method of maximum repetitions and measures of blood pressure (BP) were measured before and after training (PAPr?1 and PAP?s1) and before and after each training session (PAPre2 and PAP?s2), in place of training. DNA samples were isolated from peripheral blood leukocytes polymorphism and insertion / deletion (ID) of the ACE gene (rs1800795) was genotyped by polymerase chain reaction (PCR) plus PCR-confirmatory. The genotype distribution of the polymorphism ID attended the prerogatives of Hardy-Weit?herg. There was variation in power levels before and after training and the age between groups (t-test) and the ACE polymorphism (ANOVA) (p <0.05). Depending on the results it was concluded that resistance training helps to reduce SBP and increased muscle strength of upper and lower limbs when considering the age and ACE polymorphism. In this study the Elderly carriers of the D allele were more reactive to changes in BP resistance training. This study was multidisciplinary project involving researchers in the areas Medical, Physical Education, Pharmacy, Nutrition, Gerontology and Statistics. This fulfilled the requirements of the multidisciplinary Graduate Program in Health Sciences / As altera??es fisiol?gicas induzidas pelo processo de envelhecimento s?o din?micas e progressivas, reduzindo a capacidade de adapta??o e autonomia do idoso, podendo ser influenciada por fatores gen?ticos e ambientais. Assim o objetivo desta tese foi verificar a associa??o entre o polimorfismo ID do gene da ECA e os fen?tipos de for?a muscular e press?o arterial sist?mica de 62 idosas brasileiras (67,35?5,66 anos) durante um programa de 16 semanas de treinamento supervisionado. As idosas foram estratificadas pela idade, sendo o grupo1 (G1, n=34 )<70 anos e grupo 2 (G2 n=28)≥ 70 anos, e em tr?s grupos pela ECA, ECA-II (n=8) ECA-DD (n=35) e ECA-ID (n=19). O n?vel de for?a muscular foi avaliado pelo m?todo de repeti??es m?ximas e as medidas da press?o arterial (PA) foram aferidas antes e ap?s o treinamento (PAPr?1 e PAP?s1) e antes e ap?s cada sess?o de treino (PAPre2 e PAP?s2), no local de treinamento. Amostras de DNA foram isoladas a partir de leuc?citos de sangue perif?rico e o polimorfismo de inser??o/dele??o (ID) do gene ECA (rs1800795) foi genotipado pela rea??o em cadeia de polimerase (PCR) acrescida de PCR-confirmat?ria. A distribui??o genot?pica do polimorfismo ID atendeu as prerrogativas do equil?brio de Hardy-Weit?herg. Houve varia??o nos n?veis de for?a pr? e p?s-treinamento e entre os grupos pela idade (teste t) e pelo polimorfismo da ECA (ANOVA) com (p<0,05). Em fun??o dos resultados concluiu-se que o treinamento contra resist?ncia contribui para redu??o da PAS e aumento da for?a muscular de membros superiores e inferiores quando consideradas a idade e o polimorfismo da ECA. Neste estudo as Idosas portadoras do alelo D foram mais reativas as varia??es da PA ao treinamento resistido. A realiza??o deste estudo teve car?ter multidisciplinar, envolvendo pesquisadores das ?reas Medicina, Educa??o F?sica, Farm?cia, Nutri??o, Gerontologia e Estat?stica. Este aspecto preencheu os requisitos da multidisciplinaridade do Programa de P?s-gradua??o em Ci?ncias da Sa?de
