Global Active Stretching (SGA®) Practice for Judo Practitioners' Physical Performance Enhancement.

In order to analyze the Global Active Stretching (SGA®) practice on the physical performance enhancement in judo-practitioner competitors, 12 male athletes from Judo Federation of Sergipe (Federação Sergipana de Judô), were divided into two groups: Experimental Group (EG) and Control Group (CG). For 10 weeks, the EG practiced SGA® self-postures and the CG practiced assorted calisthenic exercises. All of them were submitted to a variety of tests (before and after): handgrip strength, flexibility, upper limbs' muscle power, isometric pull-up force, lower limbs' muscle power (squat-jump - SJ and countermovement jump - CMJ) and Tokui Waza test. Due to the small number of people in the sample, the data were considered non-parametric and then we applied the Wilcoxon test using the software R version 3.3.2 (R Development Core Team, Austria). The effect size was calculated and considered statistically significant the values p ≤ 0.05. Concerning the results, the EG statistical differences were highlighted in flexibility, upper limbs' muscle power and lower limbs' muscle power (CMJ), with a gain of 3.00 ± (1.09) cm, 0,42 ± (0,51) m and 2.49 ± (0.63) cm, respectively. The CG only presented statistical difference in the lower limbs' test (CMJ), with a gain of 0,55 ± 2,28 cm. Thus, the main results pointed out statistical differences before and after in the EG in the flexibility, upper limbs and lower limbs' muscle power (CMJ), with a gain of 3.00 ± 1.09 cm, 0.42 ± 0.51 m 2.49 ± 0.63 cm, respectively. On the other hand, the CG presented a statistical difference only the lower limbs' CMJ test, with a gain of 0.55 ± 2.28 cm. The regular 10-week practice of SGA® self-postures increased judoka practitioners' posterior chain flexibility and vertical jumping (CMJ) performance.

Reeducação Postural Global: uma revisão da literatura / Global Postural Re-education: a literature review

CONTEXTUALIZAÇÃO: O método de Reeducação Postural Global (RPG) tem sido utilizado na clínica com relatos de benefícios para a prevenção e recuperação de disfunções musculoesqueléticas. Após duas décadas de aplicação, estudos têm verificado sua eficácia no tratamento de diferentes condições clínicas e ele tem sido comparado com outros recursos fisioterapêuticos. Entretanto, são poucos os estudos voltados à comprovação dos princípios defendidos pelo autor do método, o que torna frágeis as argumentações em favor dele. OBJETIVO: Realizar, com base na literatura científica, uma análise crítica dos efeitos da intervenção fisioterapêutica utilizando o método RPG. MÉTODOS: Pesquisaram-se as bases de dados Medline, SciELO, LILACS e PeDRO, de 2000 a 2010, considerando os unitermos: RPG, alongamento global e alongamento ativo. RESULTADOS: Foram encontrados 25 estudos, sendo 13 relacionados ao método RPG e oito aos alongamentos global e ativo, além de três livros e uma tese. Após análise, 20 referências foram utilizadas. CONCLUSÕES: Parte dos estudos aponta que o método RPG é mais efetivo, enquanto outros mostram resultados similares a outros métodos de intervenção fisioterapêutica. Estudos indicam benefícios do método na melhora da força muscular respiratória, expansibilidade torácica, mobilidade toracoabdominal e da pressão respiratória máxima, além de reduzir a dor, a perda de urina em mulheres incontinentes, melhorar a flexibilidade, a atividade eletromiográfica nas disfunções temporomandibulares e a estabilidade postural em alterações ortopédicas de membros inferiores. Limitações metodológicas observadas sugerem a necessidade de maior rigor em futuras pesquisas.

BACKGROUND: The Global Postural Re-education (GPR) method has been widely used in clinical practice, with reported benefits for prevention and rehabilitation of musculoskeletal dysfunctions. In parallel with almost two decades of clinical implementation, research studies have tested and verified the effectiveness of GPR in treating different clinical conditions and have also compared this method with other physical therapy resources. However, few studies focused on the verification of the principles of mechanisms of action defended by the author of the method making the arguments in favor of the method weak. OBJECTIVE: To perform a critical systematic review of the effects of physical therapy intervention that use the GPR method. METHODS: We searched Medline, SciELO, LILACS and PeDRO, from 2000 to 2010, considering the key words: Global Postural Re-education, global and active stretching. RESULTS: We found 25 studies, 13 about GPR and 8 about global and active stretching in addition to three books and a thesis. After analysis, 20 references were included. CONCLUSIONS: Some of the studies indicated that the GPR method was more effective than other physical therapy interventions, while others demonstrated similar results of GPR when compared to other physical therapy interventions. Studies showed benefits of the GPR in improving the respiratory muscle strength, chest expansion, maximal respiratory pressure and in reducing pain, loss of urine in incontinent women, increasing flexibility, the electromyographic activity in temporomandibular disorders and postural stability in lower limb orthopedic alterations. Methodological limitations observed suggest the need for greater rigor in future research.
