Studies concerning the correlation between some metabolic parameters and the sport performance

The subjects of our study, which has lasted for a sport competitive year (2004-2005), were represented by 16 male volleyball players. The work methods were: determination of lactacidemia in basal conditions, during training and recovering, 60 minutes after the completion of training and after official games (6th and 14th lap), when we have determined lactacidemia in the day of the official game, 3 minutes after the game and 60 minutes after it (period of recovering). Comparative data concerning lactacidemia achieved in the day of an official game and 2 months after the performance of an anaerobe test with cycloergometer reveal the fact that the basal values are similar, while the values after 3 minutes of effort (volleyball game or cycloergometer) and after 60 minutes of effort are higher at the effort performed on cycloergometer than in the game. This thing shows that from a metabolic point of view, athletes behave more economically in a game than on cycloergometer; this is the so-called metabolic training. These data may suggest that volleyball players improve their anaerobe behavior through adaptative changes, and that there are significant differences between the response to the specific effort and the standard laboratory response.

Key words:

lactacidemia, training, recovering
