Correct nutrition structure can influence the main biochemical indicators of metabolic imbalance in athletes.

Background. Proper sports training periodization and correct imposition of energy recovery methods will ensure the efficiency of the athletes' activity. Aims. Adapting food intake, based on the determined energy costs of individual athletes can help the implementation of a diet that will mantain metabolic balance. Methods. A clinical study was conducted on a group of 12 elite rowers in the beginning of the general training period, during November-December 2015. The study provided biochemical monitoring in two distinct periods (P1, P2), characterized by different quantitative/qualitative diets. The entire study was conducted over 20 days in which the effort performed during the training seasons was linear. Among the mentioned periods (P1, P2) we studied the following biochemical parameters: pH, HCO3, pCO2, pO2, BE, SBE, SBC, Ca++, Mg++, LDH, GPT, T-Pro, Alb. Results. We obtained statistically significant data between the two periods (P1, P2), concerning the pre-intervention BE value (0.17±0.83) and the post-intervention BE (2.16±1.44) value. Also, the pre-intervention GPT value (46.67±24.63) was different from the post-intervention GPT value (24.08±5.29); statistically significant values were also found regarding Hb, pH, GPT, LDH, T-Pro, Alb, Ca, Mg pre-intervention and post-intervention. Conclusions. Individualization of diet will represent a benefit regarding parameters that reflect the stage of body recovery after the training season. These include HCO3, pH, GPT, along with Ca and Mg, whose serum values may be increased in the presence of elevated values of pCO2, HCO3, and BE, indicating impaired respiratory recovery, and also decreased activity efficiency.
