Resumo: | Introduction: The best relationship between length and stride frequency in running is the objective of several studies, however, the literature does not present data regarding the distance of 400 meters. Objective: To assess the influence of stride frequency (SF) modulation in the 400-meter run on heart rate (HR) and stride length. Methods: 10 healthy men (26 ± 3 years) participated in the study. Three series of 400 meters were performed with intervals of 5 minutes of rest, using: Preferred SF; 10% lower SF; and 10% higher SF. There was randomization of the order of the series and the HR was monitored during the tests and at rest. The length and SF data, mean HR during the run, maximum HR and HR amplitude in recovery were compared using Student's t tests, associated with the evaluation of the magnitude of the differences (effect sizes - ES). Substantial effects were considered when large magnitudes of difference (ES> 0.8) and p <0.05 were observed. Results: There was no substantial difference for the average HR during the runs with different relationships between frequency and stride length. Comparing the mean HR during the run, the maximum HR and the amplitude of the latter during the recovery period, there was no significant difference according to preferred SF and higher SF. Conclusion: The variation in SF 10% greater or less than the preferred SF was not enough to affect HR. |

Objetivo: Avaliar a influência da modulação da frequência de passada (FP) na corrida de 400 metros sobre a frequência cardíaca (FC) e o comprimento da passada. Métodos: Participaram do estudo 10 homens saudáveis (26 ± 3 anos). Realizaram-se três séries de 400 metros com intervalos de 5 minutos de repouso, utilizando: FP preferida; FP 10% menor; e FP 10% maior. Houve randomização da ordem das séries e a FC foi monitorada durante os testes e no repouso. Os dados de comprimento e FP, FC média durante a corrida, FC máxima e amplitude da FC na recuperação foram comparados utilizando testes t de Student, associados à avaliação da magnitude das diferenças (effect sizes – ES). Efeitos substanciais foram considerados quando grandes magnitudes de diferença (ES>0,8) e p<0,05 foram observados. Resultados: Não houve diferença substancial para a FC média durante as corridas com diferentes relações entre frequência e comprimento de passada. Comparando FC média durante a corrida, FC máxima e amplitude desta no período de recuperação, não se observou diferença significativa segundo FP preferida e FP maior. Conclusão: A variação na FP 10% maior ou menor do que a FP preferida não foi suficiente para afetar a FC.Exército Brasileiro2020-11-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistadeeducacaofisica.emnuvens.com.br/revista/article/view/84910.37310/ref.v89i2.849Journal of Physical Education; Vol. 89 No. 2 (2020); 78-87Revista de Educação Física / Journal of Physical Education; v. 89 n. 2 (2020); 78-872447-89460102-846410.37310/ref.v89i2reponame:Revista de Educação Físicainstname:Centro de Capacitação Física do Exército (CCFEX)instacron:CCFEXporhttps://revistadeeducacaofisica.emnuvens.com.br/revista/article/view/849/2857Copyright (c) 2020 Revista de Educação Física / Journal of Physical Educationinfo:eu-repo/semantics/openAccessFerreira, Wesley AlbanoBini, Rodrigo Rico2023-02-08T16:50:19Zoai:ojs.revistadeeducacaofisica.emnuvens.com.br:article/849Revistahttps://revistadeeducacaofisica.emnuvens.com.br/revistaPUBhttps://revistadeeducacaofisica.emnuvens.com.br/revista/oai||revistaef.ccfex@gmail.com2447-89460102-8464opendoar:2023-02-08T16:50:19Revista de Educação Física - Centro de Capacitação Física do Exército (CCFEX)false |
