Behavior of the creatine kinase enzyme after acute exercise protocol of eccentric contraction in untrained young people

Abstract

Introduction: Unusual vigorous physical exercise, with high eccentric demands, triggers in the musculoskeletal system, the rupture of sarcomeres, characterizing the muscular damage induced by the physical exercise that entails a series of physiological responses, the main one in cellular terms, the extravasation of proteins among them, stand out creatine kinase, to the bloodstream due to increased permeability of the sarcoplasmic membrane. Objective: to verify the behavior of Creatine Kinase concentrations in young adults in a plyometric protocol at baseline, 24h, 48h and 72h. Materials and Methods: the sample consisted of 10 individuals, with mean age in years 22.5 ± 3.3; the measurement of creatine kinase concentrations in the pre and post periods (24 hours, 48 hours, and 72 hours) after plyometrics exercise protocol (Jumps). Results: The mean CK concentration for the pre-exercise moment was 75.83 ± 93.82; after 24 hours was 125.12 ± 37.22; after 48 hours 115.30 ± 49.34 and in the post 72 hours was 77.08 ± 30.37. Discussion and Conclusion: Based on the data, we can infer that the creatine kinase concentration in the sample group was similar to that reported in scientific literature with similar studies, that is, at the pre-24-hour post exercise period, with a decline at 48 hours and 72 hours.
