Muscle fatique and muscle damage in strength training

Background and Study Aim. The aim of this study is to investigate the effects different types contractions on muscle damage fatigue in sedentary individuals.
 Material Methods. Thirty healthy male individuals participated study. Strength training applied was 3 times a week for 8 weeks. Before study, loads were determined by making maximal force measurements all subjects. 30 subjects participating divided into groups: isometric (n = 10), concentric 10) eccentric contraction group. Appropriate amount blood samples taken from elbow vein 2 subjects, before studies at end 8-week strength training.
 Results. It observed that eight-week did not cause groups create statistically significant difference (P> 0.05). with eight weeks significantly increased serum lactate dehydrogenase (LDH), C-reactive protein (CRP), myoglobin (Mb), interleukin 6 (IL-6) levels, while reduced aspartate amino transferase (AST) levels. LDH, CRP, AST, Mb IL-6 reducing tumor necrosis factor alpha (TNF-α) creatine kinase (CK), levels compared period, but show same effect other parameters.
 Conclusions. As result, it can be said performed leads more than training.
