Resumo: | PURPOSE: To verify if there is an electromyographic economy and/or an increase in the variables of vertical jumps, both as a function of the use of the Stretch-Shortening Cycle and to compare the findings between young and old women, both active. METHODS: The sample consisted of a group of elderly (GI) and a group of young (GJ), both female. The power was measured through the contact platform and electromyographic activity of the muscles: biceps femoris (BF), rectus femoris (RF), medial gastrocnemius and vastus lateralis, through vertical jumping tests: Squat Jump (SJ) and Counter Movement Jump (CMJ). RESULTS: All the muscles evaluated did not present a statistically significant difference in the electromyographic activation and the comparisons of the mean percentage of use of the Stretch-Shortening Cycle (CAE), but it was observed that for the vastus lateralis and rectus femoris muscles there were significant differences in the comparisons between the two types of jumps of both groups, GI (236.89±115.66 for SJ and 230.45±109.10 for vastus lateralis muscle (VL) CMJ and 155.42±49.06 for SJ and 155 , 45±61.78 for the CMJ of the RF muscle) required greater neuromuscular activation to jump less than GJ (117.40±133.09 for SJ and 133.09±60.71 for VL muscle CMJ and 106.72±34.15 for the SJ and 108.87±38.85 for the CMJ of the RF muscle). CONCLUSIONS: The present study confirms that there was no statistically significant difference in the use of CAE in both groups (GI and GJ). However, when it comes to the skipped height and the power developed, there were statistically significant differences in the comparison of the groups. |

MÉTODOS: A amostra foi constituída por um grupo de idosos (GI) e um grupo de jovens (GJ), ambos do sexo feminino. Foi mensurada a potência através da plataforma de contato e atividade eletromiográfica dos músculos: bíceps femoral (BF), reto femoral (RF), gastrocnêmio medial e vasto lateral, através de testes de saltos verticais: Squat Jump (SJ) e Counter Movement Jump (CMJ). RESULTADOS: Todos os músculos avaliados, não apresentaram diferença estatisticamente significativa, na ativação eletromiográfica e nas comparações do percentual médio de utilização do Ciclo Alongamento-Encurtamento (CAE), mas se nota que para os músculos vasto lateral e reto femoral houveram diferenças significativas nas comparações entre os dois tipos de saltos de ambos os grupos, GI (236,89±115,66 para o SJ e 230,45±109,10 para o CMJ do músculo vasto lateral (VL) e 155,42±49,06 para o SJ e 155,45±61,78 para o CMJ do músculo RF necessitou de maior ativação neuromuscular para saltar menos que o GJ (117,40±133,09 para o SJ e 133,09±60,71 para o CMJ do músculo VL e 106,72±34,15 para o SJ e 108,87±38,85 para o CMJ do músculo RF). CONCLUSÕES: O presente estudo constata que não houve diferença estatisticamente significativa na utilização do CAE, em ambos os grupos (GI e GJ). Porém, quando se trata da altura saltada e a potência desenvolvida, houveram diferenças estatisticamente significativas na comparação dos grupos.Editora da PUCRS - ediPUCRS2018-09-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/pajar/article/view/3008810.15448/2357-9641.2018.1.30088PAJAR - Pan American Journal of Aging Research; Vol. 6 No. 1 (2018); 15-21PAJAR - Pan-American Journal of Aging Research; Vol. 6 Núm. 1 (2018); 15-21PAJAR - Pan-American Journal of Aging Research; v. 6 n. 1 (2018); 15-212357-964110.15448/2357-9641.2018.1reponame:PAJAR - Pan American Journal of Aging Researchinstname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUCRSporhttps://revistaseletronicas.pucrs.br/ojs/index.php/pajar/article/view/30088/17231Copyright (c) 2018 PAJAR - Pan-American Journal of Aging Researchinfo:eu-repo/semantics/openAccessRosa, Hyago Bernardes daBarbosa, Igor MartinsScisleski, Eduardo PortoPrusch, Samuel KlippelLemos, Luiz Fernando Cuozzo2018-09-03T17:17:11Zoai:ojs.revistaseletronicas.pucrs.br:article/30088Revistahttp://revistaseletronicas.pucrs.br/ojs/index.php/pajar/about/editorialTeamPRIhttp://revistaseletronicas.pucrs.br/ojs/index.php/pajar/oaicataldo@pucrs.br||pajar@pucrs.br2357-96412357-9641opendoar:2018-09-03T17:17:11PAJAR - Pan American Journal of Aging Research - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false |
