Concentration of Phosphorus in the Blood of Young Men Aged 18–21 as an Informative Biochemical Marker for Assessing Adaptation Processes in Strength Fitness

The results of the research concerning further solution of the problem of finding informative markers for the diagnostic of the youth functional state which will allow to comprehensively evaluate the efficiency of the mechanisms for optimizing the training process in strength fitness are represented in this article. Two groups of young men aged 18 to 21 years participated in the research. Each group used our models of training for 3 months. The models differed significantly in terms of amount and intensity of loads. The results indicate that despite the use of sufficiently high parameters of loading intensity by the participants of the basic group under the experimental model of training, we have got a significant increase in their strength possibilities by 33.1% and their body girth parametres by 11.7% compared with the initial data. The dynamics of similar indicators fixed among the representatives of the control group also shows growth but almost twice less. At the same time, the results of monitoring the concentration of phosphorus in serum of the examined contingent, which plays an important role in energy metabolism during the process of muscle activity and reflects the mechanisms of oxidative phosphorylation, enable us to assume that the most pronounced adaptive changes in the organism during this training process are found in a group of people who have used the experimental model of fitness. This model is based on the mechanisms of reducing the duration of rest between the sets and the number of repetitions that affected the total amount of loading.
