Efeito de um mês de destreinamento sobre a aptidão física relacionada à saúde em programa de mudança de estilo de vida

Abstract

Effects of One Month2 ) e realizados testes motores para flexibilidade (FLEX), força de membros inferiores (FMI) e superiores (FMS) e consumo máximo de oxigênio (VO 2máx. ) no início do programa (MI), após nove meses de treinamento (MT) e após pausa de um mês (MD). O tratamento estatístico utilizado foi ANOVA com nível de significância de 5% e o teste de Tukey para a localização das diferenças entre os grupos, quando a mesma foi constatada. Os resultados mostraram que ganhos significativos de 22% e 7% na força de membros inferiores e VO 2máx. respectivamente, alcançados com o treinamento foram mantidos após a interrupção do programa por um mês; enquanto que o aumento de 8% na flexibilidade retornou aos níveis basais após o período de destreinamento. Conclui-se que embora mantidos os ganhos de força de membros inferiores e capacidade aeróbica adquiridos, um mês de destreinamento foi suficiente para perder a flexibilidade conquistada.Palavras-chave: exercício físico, saúde, interrupção do treinamento. ABSTRACTPhysical exercise induces hemodynamic/ventilatory and neuromuscular adaptations that can be reverted with interruption of the training program. The aim of the present study was to evaluate the effect of detraining on physical fitness related to health. Forty-four healthy subjects, both male and female, aged 57.6±8.9 years performed the 'Mexa-se Pró-Saúde' protocol with nutritional orientation and supervised physical exercises for nine months. The program consisted of aerobic, localized muscular endurance and flexibility exercises, with duration 80 minutes/session, five days/week. Only subjects who participated in the program for more than three days/week have been selected. The detraining period was one month. Weight (kg) and height (m) were measured and the body mass index (BMI) calculated. Additionally, motors tests to evaluate the flexibility (FLEX), strength of lower limbs (SLL) and upper limbs (SUL), and maximal oxygen uptake (VO 2máx ) were conducted in the beginning of the study (MI), after nine months of practicing (MT) and after detraining period (MD). ANOVA (p<0.05) and Tukey test to show the difference between groups when it evidence were used for statistical treatment. The results showed that the gains of 22% and 7% on SLL and VO 2máx respectively, obtained with the training, have not changed during the detraining period; however, the flexibility gain of 8% returned back to baseline after the detraining period. BMI and SUL did not change during the study. Although the lower limbs strength gains and maximal oxygen uptake obtained have been kept, one month of detraining was enough for losing the flexibility acquired.

Repercussions of training and detraining by water-based exercise on functional fitness and quality of life: a short-term follow-up in healthy older women

“…Although the lower body strength did not return to the baseline levels when exercise was stopped, our results are similar to those of others using a different exercise modality in an older people13,16,25,26 and indicate that lower body strength scores decrease significantly and are similar to UN scores after detraining. Our subjects had a decrease in upper body strength as early as after 4 weeks of detraining, and returned to baseline at the sixth week of detraining.…”

“…A similar behavior was observed in individuals without CP. Michelin et al (22), when assessing the effect of one month of posttraining on physical itness of 44 individuals, concluded that at the end of their treatment protocol, the strength gains of the lower limbs and aerobic capacity were maintained, with only loss in lexibility.…”

Retenção da capacidade funcional em mulheres idosas após a cessação de um programa de treino multicomponente: estudo longitudinal de 3 anos

“…Estes decréscimos poderão ser justificados com o aumento da regularidade da prática de exercício físico que atenua os efeitos do destreino. Comparativamente com outros estudos, os nossos resultados são similares em relação ao valores de força muscular Häkkinen, Alen, Kallinen, Newton, & Kraemer, 2000;Kalapotharakos, Smilios, Parlavatzas, & Tokmakidis, 2007;Toraman, 2005) e similares em relação aos valores de flexibilidade dos membros superiores e inferiores Michelin, Coelho, & Burini, 2008;Toraman, 2005).…”
