Description
Summary:The objective of this study was to compare exercise-induced muscle damage and DOMS in trained and sedentary woman. Were selected 18 woman divided in two groups: trained (19.75 ± 2.43 years) and sedentary (20.37 ± 0.91 years). Creatine Kinase (CK) was used as indirect marker of muscle damage. The samples was collected before, immediately after, 24 e 48h after the session of DROP-SET force training. We used a scale of pain perception that indicated since nothing pain until very pain, equivalent 0-10 cm, respectively. All the results was express as average ± error standard. The trained group presents concentration peak of (CK) in the time 24h a increase 211.21% when compared with time before. While the sedentary group presents concentration peak of (CK) in the time 48h, a increase 99.34% when compared with time before. However the sedentary group related 49.59% more pain that the trained group in the time 24h and 42.08% more pain in the time 48h after exercise. Based in the results it can be concluded that the trained group expressed greater muscular damage that the sedentary group and that both had presented DMIT, however the curve of the DMIT did not occur of similar form to the alterations in the CK concentration. Key words: Muscle Damage, Muscle Soreness, Creatine Kinase. O objetivo deste estudo foi comparar a magnitude do dano muscular induzido pelo treinamento de forca e da dor muscular de inicio tardio (DMIT) entre mulheres treinadas e destreinadas. Foram selecionadas 18 mulheres divididas em dois grupos: treinadas (19,7 ± 2,4 anos) e sedentarias (20,3 ± 0,9 anos). Utilizou-se como marcador de dano muscular a concentracao serica de CK. As amostras foram colhidas antes, imediatamente apos, 24 e 48 horas apos a sessao de treinamento de forca em DROP-SET. Utilizamos uma escala de percepcao de dor que indicava desde nada dolorido a muito dolorido, equivalente a 0-10 cm respectivamente. Todos os dados foram expressos como media ± Erro Padrao da Media (EPM). O grupo treinado apresentou pico de concentracao de CK no tempo 24h, um aumento de 211,21% em relacao ao momento Pre. Ja o grupo sedentarias apresentou pico na concentracao de CK no tempo 48h, um aumento de 99,34% em relacao ao tempo Pre. Porem o grupo sedentarias relatou 49,59% mais dor que o grupo treinado no tempo 24h e 42,08% mais dor no tempo 48h apos o estimulo. Baseado nos resultados pode-se concluir que o grupo treinado expressou maior dano muscular que o grupo sedentario e que ambos apresentaram
