CAPILLARY BLOOD LACTATE LEVELS AFTER JUDO MATCHES IN MALE AND FEMALE COMPETITORS. GENDER RELATED DIFFERENCES
Journal Title: Medycyna Sportowa - Year 2008, Vol 24, Issue 3
Abstract
[b]Background. [/b]Blood lactate level (LA) is considered a marker of exercise intensity and muscle glycolysis. Our study was undertaken to determine blood lactate levels following official judo matches in relation to exertion duration and competitors' gender.[b]Material and methods. [/b]The whole study was carried out over the period of 1995-2007, among athletes taking part in one-day Warsaw Judo Tournaments. Polish elite male and female judo players, except heavy weight category athletes, took part in the study. Most of them were examined several times within the above mentioned period. The subjects and their capillary blood sampled from the earlobe -5 min prior to the matches (-5 min) and following the matches (+3 min). After every first match of the tournament, blood was also sampled within a 30-minute recovery period. The overall number of observations (matches x subjects) among males and females was 135 and 127 respectively.[b]Results. [/b]The males demonstrated a higher 26% (p<0.001) post-exertion mean blood lactate level compared to the females. Both for the males and females, the post-exercise LA values correlated significantly (p<0.001, r=0.722) with the duration of the first match. For successive matches, significant correlations (p<0.001) were found between the duration of match and postexercise LA values (r=0.549), as well as between the prematch and postmatch LA values (r=0.408).[b]Conclusions. [/b]The results of our study showed the effect of match duration on postmatch LA values, gender-related difference in postmatch values of blood LA concentration prior to the final matches.
