Comparação da magnitude do dano muscular após ações excêntricas com diferentes velocidades em mulheres jovens e na pós-menopausa

TL;DRAbstract

The present study have analyzed the changes in muscle damage and inflammatory markers after an acute bout of elbow flexors eccentric exercise at difference velocities, in young and post menopausal women.37 women aged between 18 and 65 participated of the study.They were divided into four groups, (1) fast velocity, young women (n = 10); (2) slow velocity, young women (n = 9); (3) fast velocity, postmenopausal women (n = 10) and (4) slow velocity, postmenopausal women (n = 8).Eccentric exercise consisted of five sets of six maximal elbow flexors eccentric repetitions performed with the nondominant arm in an isokinetic dynamometer.It was assessed voluntary isometric contraction (MVIC), range of motion (ROM), arm circumference, muscle soreness, creatine kinase (CK), interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and prostaglandin (PGE 2 ).The MVIC, ROM, muscle soreness and arm circumference were assessed before, immediately after, 24, 48 and 72h after eccentric exercise.For the plasma
