Análise do desempenho muscular após 12 sessões de treinamento utilizando o aparelho Reformer do método Pilates

Abstract

The objective of this paper was to analyze the muscular performance in practitioners who used the equipment Reformer of the Pilates method after 12 sessions of training. Twenty-four non-smokers, healthful, young female volunteers which did not practice any modality of regular physical activity were included in this study and divided into: control group (GC, n=12) aged between 28,41 (± 4,14) years and body mass index of 24,55 (± 3,21) kg/m2; and training group (GT, n=12) aged between 29,58 (± 4,03) years and body mass index of 22,69 ± (2,87) kg/m2. Training group performed a protocol consisting of 6 exercises in the equipment Reformer. Both groups were submitted to an initial and a final assessment to analyze the performance muscular. The data obtained were analyzed and the results divided in a manner that takes into account the development of two articles. Kolmogorov and Smirnov method was applied for normal distribuction. As the sample was regular, test t was performed for intra-group analysis and non-pared t test between the groups with Welch correction. Statistical significance was set at p<0,05. The article 1 analyzed the respiratory muscular performance in practitioners who used the equipment Reformer of the Pilates method after 12 sessions of training. As assessment instruments were used the manometer to measure the maximal inspiratory and expiratory pressures; and the electromyographer, to capture the electrical activity of Rectus abdominis muscle. There was significant difference in the value of maximal final expiratory pressure (p< 0,0001) and maximal final inspiratory pressure (p<0,04) in the training group when compared to initial values. For the electromyograph there was no significant difference. It can be concluded that 12 sessions of Pilates with the equipment Reformer can improve respiratory muscle performance. The article 2 analyzed the strength of lumbar extensors, shoulder girdle and hand grip muscles in practitioners of Pilates Method with the Reformer Equipment after 12 sessions of training. The following devices were used to measure: scapular, lumbar and hand grip dynamometer. There was significant difference in the final value of lumbar dynamometry compared to the initial one (Final: 64,80 ± 10,20 kgf; Initial: 54,75 ± 10,27 kgf) and final scapular dynamometry when compared to the initial value (Final: 17,44 ± 2,88 kgf; Initial: 15,99 ± 3,54 kgf) in training group, by means of a p value<0,0001 e p<0,026. There was no significant difference for the values of hand grip. It can be concluded that 12 sessions of Pilates with the equipment Reformer can improve lumbar extension and shoulder girdle strength. To analyze the data obtained with all the applied methodology (articles 1 and 2) it can be concluded that there was an increase in the strength of the respiratory muscles, lumbar extensors muscles, and shoulder girdle muscles after 12 sessions of training using the Reformer Equipment the Pilates Method.
