          Abstract

          INTRODUÇÃO: Dentre os sistemas do organismo, acredita-se que o respiratório seja o que envelhece mais rapidamente, devido à maior exposição a poluentes ambientais ao longo dos anos. O método Pilates surge como forma de condicionamento físico particularmente interessado em proporcionar bem-estar geral ao indivíduo. OBJETIVO: Avaliar os efeitos de exercícios do método Pilates na força muscular respiratória de idosas antes e após 11 semanas de treinamento. Métodos: Trata-se de ensaio clínico, longitudinal e prospectivo. Foram selecionadas sete mulheres com idade igual e superior a 60 anos e com autonomia cognitiva preservada. A Prova de Função Pulmonar (Espirometria) foi realizada por meio do espirômetro marca Vitalograph(r) modelo 8600. A força muscular respiratória foi obtida pelas técnicas de medidas da pressão inspiratória máxima e pressão expiratória máxima, por meio de um manovacuômetro analógico da marca Gerar. O período experimental foi de 11 semanas. Para a análise comparativa dos dados obtidos nas avaliações, foi aplicado o teste t pareado e nível de significância de 5%. RESULTADOS: Os resultados do estudo mostraram aumento significativo (p≤0,01) em relação à pressão expiratória máxima de 46±18 para 75±29 cmH2O. CONCLUSÃO: Os resultados apresentaram aumento significativo na pressão expiratória máxima, sendo o método Pilates uma das práticas recomendadas à população idosa.

          INTRODUCTION: Among the systems of the organism, it is believed that the respiratory system is the one that gets older faster due to the greater exposure to environmental pollutants over the years. The Pilates method has emerged as a form of fitness particularly providing general welfare to the individual. OBJECTIVE: To evaluate the effects of Pilates' exercises on respiratory muscle strength in elderly women before and after eleven weeks of training. METHODS: This is a clinical, longitudinal, prospective trial study. We have studied seven women aged 60 and over, with preserved autonomy and cognitive skills. The Pulmonary Function Test (Spirometry) was performed using the Vitalograph(r) spirometer, model 8600. Respiratory muscle strength was obtained by technical measurements of maximal inspiratory pressure and maximal expiratory pressure, through analog Gerar manometer. The experiment lasted eleven weeks. For comparative analysis of data obtained in the evaluations, we applied the paired t test and a significance level of 5%. RESULTS: The results of this study showed significant increase (p≤0.01) compared to maximal expiratory pressure of 46±18 for 75±29cmH2O. CONCLUSION: The results showed significant increase in maximal expiratory pressure, so the Pilates method is one of the practices recommended for the elderly population.

              Mixed-methods resistance training increases power and strength of young and older men.

              This study examined the effects of mixed-methods resistance training on young and older men to determine whether similar increases in muscle power were elicited. Effects of 10 wk of a periodized resistance-training program designed to increase muscle size, strength, and maximal power on isometric squat strength, time course of force development, muscle fiber characteristics, and muscle activation (iEMG), as well as force and power output during squat jumps, were compared in young (YM, 30 +/- 5 yr, N = 8) and older men (OM, 61 +/- 4 yr, N = 10). Isometric squat strength was higher in the YM compared with OM at all testing occasions and increased over the training period by 23 +/- 15% and 40 +/- 42% for the YM and OM, respectively. The early phase of the force-time curve was shifted upward in both groups over the course of the training. During the squat jumps, the YM produced higher force and power at all test occasions and at all loads tested compared with the OM. The YM increased power output by 15 +/- 14%, 33 +/- 16%, and 26 +/- 12%, and the OM by 7 +/- 5%, 36 +/- 23%, and 25 +/- 16% for the 17 kg, and 30% and 60% 1RM loads, respectively. Although the results of this study confirm age-related reductions in muscle strength and power, the older men did demonstrate similar capacity to young men for increases in these variables via an appropriate periodized resistance-training program that includes rapid, high-power exercises.
