Aim. To test method of assessment of the functional status in skilled athletes for individualization and optimization of the training process. Materials and Methods. Three-year study involved 25 weightlifters (n = 25). All the participants were young men, aged 17-23, qualified as Masters of Sport and Candidates for Master of Sport. Results. Individualization of precompetitive conditioning in the experimental group revealed low content of lipid peroxidation (LPO) products in saliva. In the end of the experiment it was established that levels of heptanesoluble LPO in the experimental group was significantly decreased (p  0.01) as compared to Потапов В.Н., Рыбаков В.В., Антропова Е.В. Индивидуализация в системе подготовки тяжелоатлетов высокой квалификации… Человек. Спорт. Медицина 2017. Т. 17, № 1. С. 87-91 91 the control group. The significantly lower level of final LPO products was also observed in the experimental group of weightlifters (p  0.001). Conclusion. The basis of pre-competitive conditioning individualization in weightlifting is a personal scheduling of exercise in order to form the optimum level of special fitness and its transformation to readiness for maximum performance. The solution of this problem implies the assessment of the functional status at the pre-competitive stage.

We develop a connection between DP-colorings of k-uniform hypergraphs of order n and coverings of n-dimensional hypercube by pairs of antipodal (n − k)-dimensional faces. Bernshteyn and Kostochka established that the minimum number of edges in a non-2-DPcolorable k-uniform hypergraph is 2 k−1 . In this paper we use the fact that this bound is attained if and only if there exists a splitting of the n-dimensional Boolean hypercube into 2 k−1 pairs of (n − k)-dimensional faces. We give a construction of such splittings for k = 3 t . For k = 5 we prove that such splitting do not exist. Consequently every 5-uniform hypergraph with 16 (or less) edges is 2-DP-colorable.
