Efeitos de 20 sessões do método Pilates no alinhamento postural e flexibilidade de mulheres jovens: estudo piloto

Abstract

| The aim of this study was to evaluate the effects of the Pilates method on the postural alignment and joint flexibility in healthy young females. Thirty-three women aged between 18 and 30 years (56.8±8.5 kg, 1.60±0.06 m, and 22.1±2.7 kg/m 2 ) having no prior knowledge of Pilates participated in this study. They were randomly allocated into two groups: control group (without intervention) and Pilates group (PG; mat Pilates, 20 sessions, twice a week). Pre and post-program evaluation procedures were performed by a blinded investigator and were characterized by photogrammetric postural analysis (Postural Assessment Software) and assessment of joint flexibility (Wells sit and reach test). A 2×2 Analysis of Variance was used for repeated measures in order to verify differences between pre-and post-measurements for both control group and PG. No significant differences were found between the groups, for all variables. The PG presented no differences in postural alignment after the program (p>0.05). However, the PG demonstrated a significant increase of 19.1% in flexibility (p=0.036). This study showed that a program of mat Pilates produces significant effects on joint flexibility. However, 20 sessions were not sufficient to cause static postural adaptations in healthy young women. , sem conhecimento prévio de Pilates. Todas deram entrada sequencial e foram alocadas aleatoriamente em dois grupos: grupo controle (GC; sem intervenção) e grupo Pilates (GP; Pilates em solo, 20 sessões, 2 vezes por semana). O processo de avaliação pré e pós-programa foi realizado por avaliador mascarado e caracterizado por avaliação postural fotogramétrica (programa SAPO) e avaliação da flexibilidade articular (teste de sentar e alcançar no banco de Wells). Utilizou-se uma Análise de Variância (ANOVA) 2X2 para medidas repetidas para se verificar diferenças entre momentos pré e pós-programa, para o GC e GP. Não foram encontradas diferenças significantes entre o GC e GP para todas as variáveis. O GP não apresentou diferenças na postura, após o programa (p>0, 05). Entretanto, o grupo GP apresentou um ganho significante de 19, 1% na flexibilidade (p=0, 036) no momento pós. O estudo demonstrou que um programa de Pilates aplicado em solo gera efeitos significantes na flexibilidade articular. Entretanto, vinte sessões parecem não ser suficientes para causar adaptações posturais estáticas em mulheres jovens sadias.

Análise postural da coluna cervical e cintura escapular de crianças praticantes e não praticantes do método pilates

“…In children, incorrect postural habits, due to long periods in sitting posture, oversized seats, inadequate or poorly executed exercises, and heavy backpacks, result in postural disorders since the early years of schooling 5 . Furthermore, the children's body mechanics is in process of growth and their musculoskeletal structures are under development, being more susceptible to deformation 6 . Correct posture in infancy or early detection of postural disorders enable body alignment as an adult, since that period is essential for an individual's musculoskeletal development, with greater possibilities for prevention and treatment of such postural alterations, especially concerning the spinal column 7 .…”

“…In the context of postural re-education, it is known that the Pilates Method contributes positively to postural alignment of the body 6 , as this technique is based on exercises that combine strength, stretching, and breathing, which presuppose improvement in posture, in addition to physical and mental conditioning. In fact, a study confirms that the Pilates method contributes positively to body posture in young, healthy women 9 ; however, its effect on healthy children in school age is scarce.…”

Efeitos do Método Pilates na postura corporal estática de mulheres: uma revisão sistemática

“…Based on the results reported in Chart 1 and Table 2, we may affirm that there is no scientific evidence to promote the use of Pilates Method for women's posture alignment benefits. Although, among the four studies reviewed, two high-quality studies have shown that the method is able to promote general effects on posture alignment 18,20 ; and a high-quality study found no changes 7 . Hence, results are conflicting.…”

“…The study that obtained the lowest value was considered of low quality 19 . Remaining studies 7,18,20 were considered of high quality; the criteria more frequently met were the subject's distribution randomness, similarity and initial evaluation of the groups, blinding of the reviewers, acceptance of intervention, and analysis and presentation of results. Measurements of at least one key outcome were obtained in more than 85% of the subjects initially distributed per groups.…”

“…It includes muscle stretching and strengthening exercises 3,4 performed in specific equipment or on the floor; it involves concentric, eccentric and, mainly, isometric contractions, highlighting the recruitment of powerhouse muscles, which are responsible for stabilization of the body 5 . In the health sphere, Pilates Method has been used for the development of constraining physical abilities, therapeutic purposes, posture alignment, welfare, and mental discipline 6,7 . Whereas Pilates Method prioritizes the activation of postural muscles, professionals believe that the systematic practice of Pilates Method may promote positive adjustments in posture alignment 8 .…”
