ABSTRACT
BACKGROUND: Although mat Pilates (MP) has become popular, the effects of MP in hypertensive women (HW) are not entirely clear. Here, we investigated the effects of 16 weeks of MP training contrasted with MP supplemented with aerobic exercise (MP+AE) and compared with a non-intervention group on autonomic modulation, cardiorespiratory fitness, strength, flexibility, performance of functional tasks, QOL, anthropometric variables, clinical BP, and heart rate. METHODS: This is a three-arm, secondary analysis of an RCT. Sixty HW, aged 30 to 59 years, were allocated into: MP only (MP), MP+AE on a treadmill (MP+AE), and Control Group, without exercises. Assessments were performed before and after 16 weeks of training. RESULTS: The ANOVA shows differences in between-group comparisons in the SDNN, rMSSD, and SD1 in the heart rate variability analysis, with increases in rMSSD, SDNN, and SD1 only in the MP, and this result was not found in the MP+AE group (p < 0.05). Differences were observed in the between-group comparisons in time in the cardiorespiratory exercise test (CPX), flexibility, and the waist-to-hip ratio, with changes in the MP+AE, differences in QOL, and increments in the MP and MP+AE (p < 0.05). CONCLUSIONS: MP increased the indices that reflect vagal and global cardiac autonomic modulation. MP+AE improved the CPX performance, flexibility, QOL, and anthropometric variables. These results suggest that MP supplemented or not with AE has promising effects in HW.

Abstract The postural evaluation software (SAPO) has been used as a valuable tool for the analysis of postural alterations, however, such a tool depends on palpation performed by the evaluator. The aim of the present study was to evaluate the inter-and intra-examiner reliability of experienced and inexperienced examiners in measurements derived from the palpation method, and its possible influence on measurements obtained by SAPO. Nine evaluators participated in the study, which were divided into three groups according to experience with respect to palpation (GI: inexperienced group, GSE: semi-experienced group and GE: experienced group). Each evaluator performed the postural analysis of 10 volunteers, which were photographed in orthostatic position, following the SAPO recommendations. The intra-examiner reliability analysis indicated that all three groups had higher, good and moderate mean correlation values for each examiner than low correlations. In the inter-examiner reliability assessment, GE and GSE groups exhibited higher correlation values. The intra-class correlation coefficient, in the single-measure analysis, presented correlation coefficients <0.70 in 9 of the variables analyzed, indicating non-significant correlation. It was concluded that the measures analyzed by SAPO have high intra-examiner reliability. However, regarding inter-examiner reliability, the group composed of inexperienced evaluators presented lower values, suggesting that the experience time may have influenced the inter-examiner reliability regarding postural evaluation.
Resumo O Software de avaliação postural (SAPO) vem sendo utilizado como uma ferramenta valiosa para a análise das alterações posturais, porém tal ferramenta depende da palpação realizada pelo examinador. O objetivo do presente estudo foi avaliar a fidedignidade inter e intraexaminadores experientes e inexperientes nas medidas derivadas do método de palpação, e sua possível influência sobre as medidas obtidas pelo SAPO. Participaram do estudo nove avaliadores, divididos em três grupos de acordo com a experiência com relação a palpação (GI: grupo inexperiente, GSE: grupo semi experiente e GE: grupo experiente). Cada avaliador realizou a análise postural de 10 voluntários, os quais foram fotografados em posição ortostática, seguindo as recomendações do SAPO. A análise da fidedignidade intraexaminadores indicou que os três grupos apresentaram valores de correlação em média mais altos, bons e moderados, do que correlações baixas. Na avaliação da fidedignidade interexaminadores os grupos GE e GSE exibiram valores de correlação mais altos. O coeficiente de correlação intraclasse, na análise de medida única, apresentou índices de correlação <0,70 em 9 das variáveis analisadas, indicando correlação não considerável. Concluiu-se que as medidas analisadas pelo SAPO possuem uma alta fidedignidade intraexaminadores. No entanto, em relação a fidedignidade interexaminadores o grupo composto por examinadores inexperientes com relação a palpação apresentou valores mais baixos, sugerindo que o tempo de experiência dos examinadores pode ter influenciado na fidedignidade interexaminadores da avaliação postural.
