Abstract des Autors
Twelve handball players (2nd Fed Handball League) were examined in order to analyze the effects of a treadmill test on the central nervous activiation level. Critical flicker fusion frequency (CFF) was measured before as well as 5 and 15 min after a treadmill step test. The differences between pre- and post-test values were correlated with ergometric parameters such as maximum heart rate, treadmill velocity, blood lactate, and blood ammonia. Post-test values of CCF were significantly higher than pre-test ones and showed positive correlations with all indicators of work load. The closest correlation was found between maximum blood ammonia and CFF. These results are being attributed to a decrease of GABA in the brain (disinhibition) caused by the acute exercise-induced hyperammonemia. Verf.-Referat
