Among the methods that can improve football players’ motor skills, resistance training plays an important role, being one of the components of functional training in which players use their own body weight in all planes of movement. Currently in football, refining motor skills takes place on many levels, for instance, through resistance training. Optimal performance of a specific motor pattern and development of specific dominants such as stability, mobility and neuromuscular coordination increases the chance of improving the level of fitness. While discussing the importance of soccer training, attention was paid to the specific nature of work performed as well as the intensity and volume of applied effort during the broadly understood training process in football. In the aspect of developing motor skills, the role of functional loads in resistance training was emphasized which has a beneficial effect on improving speed, strength, coordination and endurance in football.

Introduction.A diet enriched with inorganic nitrates by increasing nitrite plasma levels, has been described to benefit exercise performance, blood pressure, endothelial function, and other body functions. It was also proven that additional dietary polyphenols, e.g. red wine or fruits such as strawberries, currants and berries, significantly stimulate the NO₃⁻ – NO₂⁻ – NO metabolic pathway. Aim of Study. A double-blind crossover study was performed to evaluate the influence of 8-day nitrate-rich (5.1 mmol NO₃⁻ ) juice supplementation (C – carrot juice versus B/A – beetroot juice with chokeberry addition) on blood pressure and exercise tolerance in female swimmers. Material and Methods. Eleven female swimmers volunteered for the study (age 20.9 ± 1.3 years). A two-part freestyle swimming exercise test was performed: the anaerobic part consisting of six 50 meter maximal sprints, and the endurance part consisting of an 800 meter continuous swim. Blood Pressure (BP) and Heart Rate (HR) at rest, performance time of all the distances, and peak HR after both test parts were assessed. Results. There were no significant differences in blood pressure and heart rate at rest between two measurement terms. Improvements in 50 meter sprint performance were noted in later repetitions (3-6) of the anaerobic part of the test, and they were more pronounced after B/A juice supplementation. The significant increase in the 800 meter freestyle swim performance was obtained after consuming both juices. However, during C juice supplementation this improvement was accompanied by a significant increment in peak heart rate. Conclusions. 8-day supplementation with beetroot juice with chokeberry addition increases exercise tolerance in both, repeated, maximal and endurance swims. Ergogenic effects of carrot juice with a high nitrate content seem to be possible in young female swimmers, but they still require further research.

Coordinative motor skills play a very important role in football. The target of this paper was to analyze coordinative motor skills of 12-year-old boys training football in half a year training cycle. 23 12-year-old boys who train football and 23 12-year-old boys who do not train football were diagnosed. The diagnosis was repeated after 6 months. The most popular version of Starosta’s global coordination test, with jumps to the left and right, was used to determine global motor coordination variance. Eyes and both upper and lower limbs lateralization was determined. Weight, height, length of limbs and legs muscles were measured. Somatic features of the boys did not change in a statistically significant way between the two diagnoses. However, the group of non training boys had a higher rate of both thighs muscles than the group of footballers in the first diagnosis (p ≤ 0.01). Statistically important difference in global motor coordination between the two diagnoses was determined only for the group of football training boys, and only for the results of their left legs (p ≤ 0.05). No statistically important correlation between lateralization or stature of diagnosed boys and their global motor coordination results were discovered. This configuration of the research results proves first of all the influence of football training on the level of global coordination skills. It means that Starosta’s global coordination test is a good method for testing coordinative exercises effects in young footballers’ training. The research was accomplished within the framework of grant no. N N404 255740 (40 contest), financed by the National science centre in Krakow.

Swimming classes for infants have in recent years become very popular. Internet, television, radio, books and magazines provide ever more information regarding movement classes for babies in aquatic environment. Scientific studies carried out in numerous countries showed a truly beneficial impact of movement classes on land and in water on the infants’ physical and psychomotor development. The aim of this article was to determine the motives of parents sending their children for classes of early adaptation to water environment. The study was carried out in a group of 194 parents of infants who participated in movement classes in water. A specially designed questionnaire was used as the research instrument. The questions related to biometric parameters of the babies at birth; education of their parents, as well as their attitude towards physical activity, their preferable forms of physical activity during leisure time, and the reasons for sending their children for swimming classes. Respondents’ contributions were grouped according to topic and calculated using absolute and percentage values. The results were illustrated in a form of tables and graphs, which characterized the answers of parents participating in the study. Study results showed, among others, that the basic motive determining the decision of parents participating in the research to send their children for physical activity classes in water was their urge to allow their children to adapt to water environment as well as stimulate their physical development after birth through physical activity in water.

Attending swimming lessons has become a very popular form of spending free time. The aim of the study was to determine the influence of the author’s method of visualizing motion to change swimming technique in crawl and crawl on the back in children. 50 children have been examined and 18 boys out of this group have been qualified for a detailed analysis. The examined have been divided into two groups – an experimental group realising a training program including visualisation – and a control group realising only the training program. As a part of the test method, swimming technique of swimming crawl on the back and on the chest, was registered with digital Sony camera. Then, using “Avi Image”, values of the measured attributes were defined for both swimming techniques. These included the angle of attack and the angle of the maximum bending angle of the elbow of the right and left arm. Results has represented a valuable support of training process, finished with sports success at junior level.
