Swimming is an Olympic kind of sport in which sportsmen demonstrate their technical skills and speed and also set worldwide records. The chosen sport combines the possibility of harmonious development of the body, wellbeing orientation, and emotionality. The predominant orientation of the training process in the groups of initial training is the training and improvement of swimming skills in sporting ways, the development of overall endurance, flexibility and speed of movement. The goal is to improve the technique of development of physical qualities of 5-6 year-old swimmers at the stage of initial training. Organization of the research. We divided a school year symbolically into 2 semesters. There was an indepth study of swimming techniques like crawl and backstroke and familiarization with the elements of swimming in a dolphin way during the first half of the year (October-December). The second half (January-May) was devoted to improving such swimming techniques as crawl and backstroke. Results. It is important to determine the target indicators - the final and intermediate (current), which can be judged on the implementation of tasks; develop a general scheme for constructing a training process; determine the dynamics of training parameters and loads, as well as the system of restoration of work, aimed at achieving the main and intermediate goals in order to maximize the implementation of our methodology. As a result, the best growth of the results was in the tests: flexion and unbending of the hands in lying position: Control Group (hereinafter CG) – 9,71%; Experimental Group (hereinafter EG) – 15, 21%; body inclination forward in sitting position: CG – by 6,34%; EG – 12,62%; burpee: CG – 8,65%; EG – 16,34%; high jump: CG – 8,37%; EG – 14,03%. Conclusions. The obtained results testify the effectiveness of our improved methodology, which aim is to use specially selected exercises and has an alternative percentage distribution of all components of sports training.

Introduction. Sport biomechanics focuses on the evaluation of athletes’ running stride characteristics with training shoes and barefoot. Few studies have assessed the running performance of shod and unshod preadolescent athletes, and they have been carried out only in laboratory conditions. Aim of Study: The aim of this study was to evaluate the performance of preadolescent athletes in the 1000 m running event by applying two protocols: with training shoes and barefoot. Material and Methods. Forty three (n = 43) preadolescent athletes were recruited for the study. In the fi rst testing session the participants’ anthropometric data and their VO₂max were recorded. The athletes were randomly assigned to compete in two testing protocols in counterbalanced order. The t-test assessed the performance in two protocols while the ROC curves were applied to illustrate the discrimination between performances relative to the athletes’ gender. Pearson’s correlation coefficient analysis was applied to evaluate the inter-correlations between the athletes’ VO₂max, and their anthropometric characteristics during an 1000m running event shod and unshod. Results. The results showed that boys performed better than girls in the 1000 m event, shod and unshod. Pearson’s correlation analysis presented a substantial effect on the VO₂max and body fat in the preadolescents’ performance in both protocols. In spite of the fact that boys performed slightly better than girls, the t-test did not confirm the signifi cant differences in the athletes’ 1000 m performance barefoot. Conclusions. The importance of the present study lies in the fact that the running performance of preadolescent athletes barefoot is not worse than their performance in training shoes, and this can provide an incentive for future research concerning the content of training programs of young athletes.

The purpose of our study was to determine magnesium concentrations in erythrocytes and serum in a group of young athletes before and after exercise. Our study was carried out on 30 athletes (basketball, handball and football players) from local sport clubs. Exercise tests were conducted using a cycle ergometer. The athletes exercised for 10 minutes at individual submaximal workload levels. Venous blood was drawn for the examination in the morning, after overnight fast and 1 minute after exercise completion. In the blood samples, total serum Mg concentrations were determined by calorimetric method. Erythrocyte Mg content was calculated using hematocrit, whole blood and serum magnesium concentrations. After the ergometric test, significant increases of serum Mg (0.95±0.13 mmol xdm-3 before, 0.89+0.13 mmol xdm-3 after the effort) and significant decrease of Mg in erythrocytes (2.27±0.09 mmol xdm-3 before, 2.35+0.08 mmol xdm-3 after the effort) occurred. The probable cause of the observed decrease in serum magnesium concentrations after physical effort could be a shift of Mg into the erythrocyte. Mg deficiency and depletion have often been observed in athletes. There was evidence that dietary intake may be inadequate in some individuals, thus dietary supplementation of this element can enhance performance and efficiency of energy metabolism. However, few studies indicate that Mg supplementation improves exercise performance.
