Resumo: | Aims: The effects of muscle stretching before exercise on muscle performance is controversial. The aims of this study were to compare the effects of static, ballistic, and proprioceptive neuromuscular facilitation (PNF) stretching on muscle power, flight time, and jump height. Methods: This uncontrolled, crossed intervention study included 20 young male and female students aged 18 to 28 years from Universidade Estadual do Oeste do Paraná, without any complaints of pain and with no musculoskeletal injuries. The sample was divided into four subgroups: three of them were submitted to static, ballistic, and PNF stretching, while one was the control group. The interventions occurred once weekly, alternating between the stretching modalities, over a 4-week period, at the end of which all subgroups had performed all the exercises proposed. Vertical jumps were performed on a testing mat immediately after the stretching exercises (or separately in the case of controls) in order to assess muscle performance. The repeated measures ANOVA was used for the statistical analysis and the significance level was set at 5%.Results: There was no significant difference in muscle power, flight time, or jump height before and after the application of the three stretching modalities. The following p values were obtained: 0.508 for muscle power, 0.674 for flight time, and 0.606 for jump height.Conclusions: Stretching is not contraindicated if the goal is to enhance muscle extensibility prior to vertical jumps, since, apparently, stretching has no negative effect on important variables among healthy young individuals, at least not within a 4-week period. |

Com isso, o objetivo deste estudo foi comparar o efeito do alongamento estático, balístico e da facilitação neuromuscular proprioceptiva sobre a potência muscular, tempo e altura de salto.Métodos: Para este estudo de intervenção, não controlado e cruzado, foram incluídos 20 jovens estudantes da Universidade Estadual do Oeste do Paraná, de ambos os sexos, com idade entre 18 a 28 anos, sem queixas de dor e sem lesões musculoesqueléticas. A amostra foi dividida em quatro subgrupos, sendo que três deles recebiam um dos três tipos de alongamento (estático, balístico ou facilitação neuromuscular proprioceptiva), enquanto o quarto subgrupo era o controle. As intervenções foram realizadas uma vez por semana, na forma de rodízio, ao longo de quatro semanas, ao final das quais todos os subgrupos haviam realizado todos os procedimentos em estudo. Logo após os alongamentos (ou isoladamente, nos controles) eram realizados saltos em uma plataforma de saltos verticais e avaliadas variáveis relativas ao desempenho nessa prova. A análise estatística foi feita por meio da Análise de Variância com medidas repetidas, com nível de significância de 5%.Resultados: Analisando-se as médias obtidas pelos quatro grupos para as variáveis do salto vertical, não houve diferença significativa na potência muscular, tempo ou altura de salto, antes e após a aplicação dos três tipos de alongamento. Os valores de p obtidos foram 0,508 para potência muscular; 0,674 para tempo de salto; e 0,606 para altura de salto.Conclusões: Se há objetivo de ganho de extensibilidade prévio à atividade física que envolva salto e potência, não se contraindica o uso de alongamento, visto que parece não haver influência negativa deste sobre variáveis importantes para o salto em jovens saudáveis, pelo menos dentro de um período de quatro semanas.Editora da PUCRS - ediPUCRS2016-02-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistaseletronicas.pucrs.br/scientiamedica/article/view/2144310.15448/1980-6108.2015.4.21443Scientia Medica; Vol. 25 No. 4 (2015); ID21443Scientia Medica; v. 25 n. 4 (2015); ID214431980-61081806-556210.15448/1980-6108.2015.4reponame:Scientia Medica (Porto Alegre.
