Efeitos do treinamento funcional com cargas sobre a composi o corporal: Um estudo experimental em mulheres fisicamente inativas Effects of the functional strength training on body composition: An experimental study in physically inactive women

O presente estudo objetivou analisar os efeitos do treinamento funcional com cargas (TFC) na composi o corporal de mulheres fisicamente inativas. Vinte mulheres (25.70 ± 4.20 anos) foram designadas aleatoriamente para os grupos experimental (GE, n = 10) e controle (GC, n = 10), tendo o GE realizado 12 semanas de TFC, enquanto o GC n o recebeu qualquer interven o. As variáveis antropométricas avaliadas em ambos os grupos foram: massa corporal (MC), estatura, índice de massa corporal (IMC), massa de gordura absoluta, massa corporal magra (MCM) e percentual de gordura (%G). Os testes t de Student independente e pareado foram utilizados para a compara o das médias inter e intra-grupos experimental e controle (p < .05). O GE apresentou redu es significativas nos valores de %G (p < .001), enquanto o GC aumentou seus níveis de MCM (p < .001), IMC (p < .001) e MC (p = .021). Os resultados indicaram que após de 12 semanas o TFC reduz os níveis de gordura corporal, mas n o promove aumentos de MCM em mulheres fisicamente inativas. This study aimed to analyze the effects of the functional strength training (FST) on body composition of physically inactive women. Twenty women aged between 19 and 34 years old (25.70 ± 4.20 yr.) were randomly assigned to experimental (EG, n = 10) and control group (CG, n = 10). The EG performed 12 weeks of FST, while CG did not receive any intervention. The anthropometric variables evaluated in both groups were: body mass (BM), height, body mass index (BMI), absolute fat mass (AFM), lean body mass (LBM) and fat percent (%F). The paired and independent samples t tests were used to identify modifications between and within experimental and control groups (p < .05). The EG decreased %F values (p < .001), while CG increased the LBM (p < .001), BMI (p < .001) and BM (p = .021). Results showed that after 12 weeks FST can be useful to reduce body fat mass, but it doesn’t promote increases on LBM of physically inactive women.
