Purpose. Among the factors conditioning sport performance in athletics, competition stress it is one of the most "active" with high bio-psychic effects, especially in competition season. We set highlighting certain biological reactions determined by induction of "start condition", as competition stress factor to athletes, specialized on medium or long events. Methods. The research implied 10 subjects with different "age" in athletics and in specialty of the event practiced. The athletes were subjected to two tests, in two different days, in a week that finalized with an important competition. (testings made with 7 days, respectively one day before). Results. The analyses of the values to the variables subjected to research (lactic acid, hemoglobin, glucose and magnesium) show modifications in competitional stress situations, at the subjects researched, in the purpose of rising some of the values to some variables and the decrease of other values, to other variables. Conclusions. The stress in the competitional season determines biological modifications to the professional athletes, specialized on medium-long events. [ABSTRACT FROM PUBLISHER] |
