| Abstract | |
The objective of this research was to observe the effect of different road cycling competitions and a 20 days break period in Creatine Kinase (CK), Lactate Dehydrogenase (LDH), Interleukin-1(IL-1), Interleukin-6 (IL-6), Factor necrosis tumoral-alpha (TNF-<font face=\"symbol\">a), prostaglandin E2 (PGE2) and in the ratio of Glutamine/Glutamate (Gln/Glu). The hypothesis tests were conducted with a sample of 12 professional cyclists which have completed 3 different road cycling races. The first and third ones (C1 and C3) were mass start races. The second one was a stage racing (C2). One analysis was made after a 20 days break period (C3). Blood samples were collected 24 hours before and 24 hours after each competition. There were no significant differences for none of the inflammatory mediators (p<0,05). Increases (p<0,05) were detected after the end of C2 and C3 for CK and LDH and low (p<0,05) in the ratio of Gln/Glu at C3. The conclusion of the research was that muscular damages are diagnostified in professional road cyclists 24 hours after the end of the stage racing and after mass start competition preceded by 20 days a break period.
