Effect of one-session vigorous training on muscular damage and renal function markers in elite karate athletes

Authors

Abstract

 Objective: Aim of this investigation was to study the
effect of one-session karate training on muscle and renal damage markers in
karate athletes.   Materials and Methods: In this cross-sectional study with
pre- and post-test design, 10 elite volunteer male athletes were selected and
participated in one-session training (2 hours). Urine and blood samples were
collected before training and one hour after training and urine samples was
collected 6 hours after training, too. Urinary and plasma creatinine, LDH and
CK values were measured through laboratory methods. Data was analyzed using
descriptive statistics, repeated measures, paired sample t test and Wilcoxon
with 95% of confidence level.    Results: There were significant differences between urinary
values of creatinine, LDH and CK in the three sampling phases (p < 0.05 There
were also significant differences between the mean urinary and blood values of
creatinine, LDH and CK within pre-exercise and 1 hour post-exercise values and
urinary values of creatinine, LDH and CK within 1 hour post-exercise value and
6 hours post-exercise, too (p < 0.05).   Conclusion: It seems that a session of intensive karate
training can increase muscular damage and renal function markers but these
values decreased to initial measures 6 hours after training.
