The effects of spring (300 m) running on plasma lactate, uric acid, creatine kinase and lactate dehydrogenase in competitive hurdlers and untrained men

BACKGROUND: High intensity exercise may induce muscle damage especially in individuals unaccustomed to regular physical efforts. Our aim was to compare the impact of 300 m sprint running on muscle enzymes release into blood in competitive hurdlers and untrained but physically fit adults. METHODS: EX...

Description
Summary:BACKGROUND: High intensity exercise may induce muscle damage especially in individuals unaccustomed to regular physical efforts. Our aim was to compare the impact of 300 m sprint running on muscle enzymes release into blood in competitive hurdlers and untrained but physically fit adults. METHODS: EXPERIMENTAL DESIGN: Comparative study. SETTING: General community. PARTICIPANTS: Nine competitive hurdlers (CH; 21.3 yrs+/-3.1) and six matched moderately active untrained men (UT). INTERVENTIONS: Subjects performed a single 300 m sprint running test. MEASURES: Plasma creatine kinase (CK) and lactate dehydrogenase (LD) activities, and concentrations of lactate (LA) and uric acid (UA) measured before the warm-up and 5 min, 2 and 20 hrs postrun. RESULTS: Mean runner performance achieved by CH was significantly better (35.53-s+/-0.64) and LA concentrations significantly higher (14.95 mM+/-0.59) than those recorded in UT (41.52-s+/-2.22; 10.13 mM+/-0.59). Pre- and postrun CK activities until the 2nd hour of recovery were found to be significantly higher (p
