The aim of our work is to find out level of somatic development and motor performance of students of the 1.st year - class of FCHPT STU in Bratislava in five years period in years 2011 – 2015 (1881 women and 797 men). We used standardized test battery to recognize motor performance. Comparison of the motion efficiency testing results we used the test of statistical significance of differences in mean values of the significance level p - value<0,05, in program Statgraphic (One Way – ANOVA). Based on the results of measuring the level of somatic development , we found out that the body height has stagnating tendency for both men and women categories. Body weight had a stable level in men until 2014 , but its value is about 5 kg higher than the population average . The women had body weight except in 2014 rising trend. Both in men and women category in 2015 significantly increased body weight . Observing body mass in dex ( BMI ) we found out a significant increase in values only for women. The relative value of the body fat in both men and women category at approximately the same level without significant difference index BMI more than men but the value of body fat on th e other hand they were worse . In the test results of motor performance , we found out significantly lower levels of aerobic endurance compared to the first measurement in 2011 , both men and women. In the case of speed - power capabilities of the arms and tors o as well as for the dynamic force abdominal and hip muscles we can ́t confirm increasing or decreasing tendency. From our research it is clear that aerobic endurance is the ability which has decreasing trend from year to year for both men and women categor y.

Aim: The aim of this study was to determine the relationships between socioeconomic factors (SES), anthropometric characteristics and motor abilities of female university students. Materials and Methods: The study was conducted in 2000-2018 on 3955 female university students aged 19.72 ± 0.75 years who were randomly selected from the population of students attending obligatory physical education (PE) classes. The participants' body mass and height were measured, and the students participated in 13 motor ability tests that assessed their speed/agility, flexibility, strength, endurancestrength, and endurance abilities. Multiple independent samples were compared using the KruskalWallis test or the mean-ranks post-hoc test when significant differences were observed in the participants' motor abilities. Results: Statistically significant differences in the participants' body mass, body height, BMI and motor abilities (speed/agility, flexibility - partly, strength, and strengthendurance) were associated with differences in the students' SES. Greater mean differences in SES were associated with differences in the anthropometric and motor characteristics of students. Environmental factors such as the place of permanent residence, monthly budgets, mother's and father's educational background were least likely to be associated with female students' endurance abilities. Conclusions: Female students who had higher monthly budgets, resided in large cities, and had better educated parents were generally taller and had a higher level of motor abilities. An inverse relationship was noted between motor abilities vs. body mass and BMI.

The purpose of this study was to analyse the interaction between somatotype, body fat and physical activity in prepubescent children. This was a cross-sectional study design involving 312 children (160 girls, 152 boys) aged between 10 and 11.5 years old (10.8 ± 0.4 years old). Evaluation of body composition was done determining body mass index and body fat by means of skin-fold measurements, using the method described by Slaughter. Somatotype was computed according to the Carter's method. Physical activity was assessed with the Baecke questionnaire. The physical activity assessment employed sets of curl-ups, push-ups, standing broad jump, medicine ball throw, handgrip strength and Margaria-Kalamen power stair. There were negative associations for body fat, endomorphy and mesomorphy with curl-ups, push-ups and broad jump tests and positive associations with ball throw, handgrip strength and Margaria-Kalamen power tests. The associations for ectomorphy were the inverse of those for endomorphy and mesomorphy. Non obese children presented higher values for curl-ups, push-ups and standing broad jump. In medicine ball throw, handgrip strength and Margaria-Kalamen power test obese children presented higher scores, followed by children who were overweight. The mesoectomorphic boys and ectomesomorphic girls performed higher in all tests. The morphological typology presented more interactions with strength than % of body fat and physical activity. These data seem to suggest that the presence/absence of certain physical characteristics is crucial in the levels of motor provision in prepubescent children.

Effect of Added Weights on the Characteristics of Vertical Ground Reaction Force During Walk-to-Run Gait Transition

Purpose. In this study, the effect of added weights on the various force and time related characteristics of vertical ground reaction force (VGRF) during the last five steps prior to walk-to-run transition was studied. Basic procedures. Experimental set up consisted of a force platform embedded treadmill. Sixteen college students performed experimental trials by carrying 0%, 10%, 20% and 30% of their body weight. During each trial, after walking for about 30 seconds the speed of the treadmill was increased manually at a rate of 0.089 m/s/s (0.2 miles/hour) until the participant started running. Main findings. A significant interaction (weights × steps) was observed for the first peak of VGRF. The trough, second peak, impulse, and rate of force development of VGRF increased with added weights. During the last five walking steps, most of VGRF parameters changed in a nonlinear fashion. Conclusions. Based on the behavior of VGRF parameters and manually recorded preferred transition speed values, we argue that the added weights would reduce the walk-to-run transition speed. We further speculate that a combination of transition determinants actively participate in the reorganization process during the last five walking steps, prompting the gait transition.

The aim of the work was to characterize physical loads present during a champion match among young footballers. The research was conducted on a group of 10 football players at the age of 13.5 ± 0.4, with training experience of 4 years. The average body height of the players was 162.32 ± 7.73 cm and the average body mass was 51.12 ± 7.72 kg. In effort to analyze the selected motor performances of the players during the match, a kinematic method by Erdmann (2000) was applied. The analysis of motor activeness was conducted during the first and the second half of the game. The results are shown as arithmetic means and standard deviation. To compare the values, Student's t-test for the linked samples was applied. The significance level was p ≤ 0.05. The results of the study show that the total distance covered by the young football players averaged 4,252 metres. The longest, statistically relevant mean distance (p ≤ 0.05) was covered by the midfielders (4, 486 m). The analysis of the mean distance covered by the players with an established speed below the anaerobic threshold was 3,596 ± 207 metres, which makes up 84.57% of the total distance covered during the game. A thorough analysis of the number of sprints revealed that a player performs 18 of them on average throughout the game. The highest maximum running speed (7.0 m/s) was achieved by the midfielders. The defenders proved to be slowest (6.5 m/s), while the forwards had the second fastest average maximum running speed (6.8 m/s).
