The integrated assessment of the functional status of soccer players in different periods of football season

The search for simple and minimally invasive methods of diagnostics of the functional status of professional soccer players was always the object of the interest of sport medicine and physiology. The aim of research was the increase of medical control of the professional soccer players by elaboration and introduction of methodology of integral assessment of the soccer players’ functional status using the program-hardware complex Fazagraf ® . Methods of research. The research included 34 professional players in the age 18-34 years. The research was carried out during the football season in different training periods and included instrumental methodology of assessment of the functional status using apparatus fazagraf and also the methodology of assessment of the functional status, offered by us. Results of research. With the help of the offered methodology it was established, that at the end of basic period the low marks of FS (1,2 and 3) were not fixed. All soccer players were in the good and very good FS. At the end of competitive period of training it was revealed, that in 11 soccer players (32%) were observed the low indices of integral assessment that is FS disorders. Conclusion: in the basic period of training takes place the increase of adaptive potential and decrease of the risk of development of disorders in sportsmen’s health. In competitive period of training were observed the disorders of functional status under the effect of big physical loads and other factors that needs more attention to the medical control in this training period

Analysis of vegetative homeostasis state of elite handball players

Purpose: to study characteristics and dynamic of elite handball players’ physiological indicators. Material: In experiment elite handball players (n=112, age 18-35 years) participated. For determination of vegetative homeostasis state we analyzed variability of heart rhythm. The researches were conducted in laboratory conditions in rest state, in lying position during 5 minutes. Results: it was found that organism’s adaptation reactions to training loads go with different tension of regulation systems. At the end of competition period there appears hyper-kinetic syndrome. It witnessed insufficiency of means, which permit to maintain optimal regulation of cardio-vascular system and increase its functional potentials. Conclusions: indicators of cardio-vascular system and their dynamic w3itnessed maintaining of high level of handball players’ organism hemodynamic provisioning. High level of vegetative homeostasis pointed at certain degree of sportsmen’s fitness. Such state is sufficient for preservation of high potential of sympathetic -adrenaline system and overcoming of fatigue processes.

Explosive force in football association: effects of competition and field location

Explosive force was assessed through squat jump (SJ), counter movement jump (CMJ), and elastic index (IE) in 21 South American football players at the beginning and the end of a six-month competitive period. Jumps were accomplished on a force platform and the data obtained were grouped according to: time, beginning and end of competitive period, and field location of the players (defenders, midfielders and attackers). T-test and Kruskal-Wallis analysis for the differences between positions were used to analyse its influence, as well as that of the competition, on the variables considered. The association between the CMJ and SJ was analysed by Pearson product- moment. The values found for SJ, CMJ and IE were below international standards. The IE showed that explosive force is significantly affected by the competitive period for those field positions implying high intensity activities during the match. The correlations suggest that differences exist on the factors that determine the significant changes for midfielders and forwards. It is concluded that the application of exercises that imply an action of the type stretch-shortening cycle (SSC) during the highly intensive competitive period could contribute to optimize the performance of the players.
