Th e aim of the presented work is to contribute to the clarifi cation of the structure of sport performance limiting factors within karate, out of which the following were chosen: disjunctive reaction time lower extremities on visual stimulus and velocity of strike seiken čoku cuki from the perspective of hierarchical formation of the mathematical model. Th e measured values were processed and the paired comparison analysis was used to fi nd the dependency rate between the particular variables. We used both regression and partial correlation analysis for creating the empirical model of the structure of selected motoric factors, which are limiting the performance in karate. On the “second level factor” concerning dependent variables which we have selected, the following motoric factors proved to be signifi cant: standing long jump, 400m run, overhead medicimbal throw and No of sit ups during 1 min. period. On the “third level factor” it were: 50m dash from standing start, No of push ups in 10 second, shuttle run 10x5m, pull ups and isometric endurance in upright possition of pull ups, calculation of maximal oxygen consumption (VO2 max).

Abstract This study presents the evaluation of chosen anthropometric and motor parameters in group of female junior competitors throughout the course of 2-year preparation of aerobic gymnastics by means of Z-scores. The observed group consisted of 12 girls (average age at the beginning of observance 14.08 ± 1.19 years). Evaluation of anthropometric (body height, body weight, body mass index, percentage of body fat, acting body weight) and motor parameters (sit-ups in 30 seconds and 60 seconds, pull-ups to bar, modified push-ups, standing long jump, backwards tandem walking, shuttle run 4×10 m, Jacík’s test) was carried out in standard conditions in nine girls at 3-month intervals. It has been confirmed that female probands with higher Z-score of motor parameters together with lower Z-score of anthropometric parameters achieved higher sport performance during the 2-year observance at competitions, with an exception of one such proband.

Background: This cross-sectional study aimed to determine whether normal, flat, or high-arched feet corresponded to better performance of certain motor tests in children. Methods: One hundred eighty-seven children (mean ± SD age, 11.15 ± 1.24 years) were recruited and divided into three groups: 96 with normal feet, 54 with high-arched feet, and 37 with low-arched feet. Nine motor trials were selected to assess motor performance: standing long jump, standing triple jump from each foot, standing vertical jump, shuttle run 10 × 5 m, standing-start 20-m sprint, static balance, dynamic balance on a beam of an inverted gym bench, and agility circuit. Results: There were no significant differences in the trial results between groups, although in eight of the nine trials participants in the high-arched group tended to perform better. Boys performed better than girls in all of the trials except those of balance. Conclusions: These results suggest that children with a certain foot type did not achieve better motor performance in the nine trials tested.

The aim of this study was to investigate the effects of physical activity with music on motor development and performance in children with developmental deficiencies. The study includes twenty children with developmental deficiencies, aged between 10-15 years old. Children were classified into two groups randomly and both groups were given 1 hour of training 3 days a week for 20 weeks. Physical activity with English and Spanish verbal song was used for the first group and only physical activity for the second group. Each participant participated in shuttle, shuttle run, flexibility, standing long jump, vertical jump tests.  The fatigue parameter of children was evaluated using the Visual Analog Scale. As a result of this study, it has been shown that physical activity with music is more effective method to improve motor development and performance levels of children with developmental deficiencies.

The purpose of this study was to examine the effects of speed training on sprint step kinematics and performance in male sprinters. Two groups of seven elite (best 100-m time: 10.37 ± 0.04 s) and seven sub-elite (best 100-m time: 10.71 ± 0.15 s) sprinters were recruited. Sprint performance was assessed in the 20 m (flying start), 40 m (standing start), and 60 m (starting block start). Step kinematics were extracted from the first nine running steps of the 20-m sprint using the Opto-Jump–Microgate system. Explosive power was quantified by performing the CMJ, standing long jump, standing triple jump, and standing five jumps. Significant post-test improvements (p < 0.05) were observed in both groups of sprinters. Performance improved by 0.11 s (elite) and 0.06 s (sub-elite) in the 20-m flying start and by 0.06 s (elite) and 0.08 s (sub-elite) in the 60-m start block start. Strong post-test correlations were observed between 60-m block start performance and standing five jumps (SFJ) in the elite group and between 20-m flying start and 40-m standing start performance and standing long jump (SLJ) and standing triple jump (STJ) in the sub-elite group. Speed training (ST) shows potential in the reduction of step variability and as an effective short-term intervention program in the improvement of sprint performance.

The main motivation for the research is a verification of applicability of the fitness test as a predictor for specific alpine skiing performance of the Czech national team of U14 and U16 categories. We want to verify if the results from the fitness test correspond with points for the performance in alpine skiing disciplines (slalom, giant slalom, super giant slalom). In total, 42 men and women (U14 and U16 categories), members of the Czech national team, participated in the research. Participants were grouped by gender (women n=21, age 14.23 (± 1.04), men n = 21, age 14.19 (± 1.07)). Fitness test consisted of six individual tests and was used as a tool to examine the level of motor abilities (jumping over the Swedish bench, shuttle run 4 × 10m, standing long jump, hurdles agility run - boomerang test, twist test, 20m shuttle run - beep test). Points for the performance in alpine skiing show the best result from a single competition transferred to the points. In our research we were looking for relationship between the points from three different disciplines (slalom, giant slalom, super giant slalom) and the results from the fitness test. In the men category we found high correlation (at the significance level of p ˂ 0.05) between super giant slalom and standing long jump (r = -0.73; r² = 0.53), between super giant slalom and boomerang test (r = 0.62, r² = 0.38) and between super giant slalom and shuttle run 4 × 10m (r = 0.61, r² = 0.37). Small correlation was found between slalom and box jump test (r = -0.31, r² = 0.1), between slalom and twist test (r = -0.33, r² = 0.11) and between super giant slalom and twist test (r = -0.34, r² = 0.12). In women category we did not found high correlation (at the sig-nificance level of p ˂ 0.05). Small correlation was found between slalom and box jump (r = -0.31, r² = 0.1), between giant slalom and twist test (r = 0.01, r² = 0.0001), between super giant slalom and standing long jump (r = -0.03, r² = 0.0009) and between slalom and shuttle run 4 × 10m (r = -0.05, r² = 0.0025). Twist test had very small correlation in both men and women categories. We can say that it is not relevant for prediction of alpine skiing per-formance. Based on different significance of correlations between men and women (super giant slalom and standing long jump; slalom/super giant slalom and shuttle run 4 × 10m) it might be necessary to adjust fitness testing as a predictor of alpine skiing performance according to a gender.

Abstract BackgroundAlthough evidence suggests that cardiorespiratory fitness is the most important component associated with future health, little is known of how it is associated with multiple other physical fitness components. Since various physical fitness aspects do not change the same as cardiorespiratory fitness during childhood, it is necessary to establish possible associations between cardiorespiratory fitness and other physical fitness components in children. Therefore, the main purpose of the study was to test the associations between cardiorespiratory fitness with motor performance and body size in 7-14-year-old children.MethodsIn this cross-sectional study, we recruited 1612 children (52.5% girls). Health-related physical fitness components included: 1) body-mass index (kg/m2) calculated from height and weight (measure of body size), 2) sit-and-reach test (measure of flexibility), 3) standing long jump (measure of explosive strength), 4) sit-ups in 30 sec (measure of repetitive strength), 5) 10x5 shuttle run test (measure of agility) and 6) 20-m shuttle run test (measure of aerobic capacity). The associations were performed using generalized estimating equations with β coefficients.ResultsAfter adjusting for age, cardiorespiratory fitness was associated with sit-and-reach test (β=0.13, p<0.001), standing long jump (β=0.59, p<0.001), sit-ups in 30 sec (β=0.53, p<0.001) and 10x5 shuttle run test (β=-0.56, p<0.001) in boys. In girls, cardiorespiratory fitness was associated with body-mass index (β=-0.12, p<0.001), sit-and-reach test (β=0.21, p<0.001), standing long jump (β=0.25, p<0.001), sit-ups in 30 sec (β=0.36, p<0.001) and 10x5 shuttle run test (β=-0.40, p<0.001). No significant associations between cardiorespiratory fitness and body-mass index in boys were observed.ConclusionsAlthough significant, cardiorespiratory fitness is weakly to moderately associated with other physical fitness components, pointing out that such measure should be tested separately from other aspects of physical fitness in school-aged children.

The aim of this research is to confirm differences in the anthropometric characteristics and motor abilities of schoolchildren aged 9 and 10 compared by sex and age. The sample comprised 341 schoolchildren, divided into two subgroups of third (172) and fourth (169) graders. The research is of a transversal character and includes the measurement of anthropometric characteristics and motor abilities by applying the Eurofit fitness testing battery. The results show a significant difference based on sex in terms of body mass (t = 2.148), and as for motor abilities, there is a difference in the Shuttle run test (t = -3.709). A statistically significant difference considering the age of the tested population was observed in height (t = -10.327) and body mass (Z = -5,991), while in terms of motor abilities there was a statistically significant difference in the values of all the tests: Hand tapping (t = 4.735), the Standing long jump (Z = -3,575), Shuttle run (t = 12,248), the Flexed arm hang (Z = -2,167), Sit and reach (Z = -2,406), Sit-ups in 30 seconds (t = -9069). The research shows a higher statistically significant difference observed in body composition, but also in the motor area of the studied group in terms of age, and in relation to the statistically significant difference that was revealed by gender.

China General Administration of Sport has published and adopted the National Physical Fitness Measurement (NPFM—preschool children version) since 2000. However, studies on intraday reliability, sensitivity, and minimum detectable change (MDC) are lacking. This study aimed to investigate and compare the reliability, sensitivity, and MDC values of NPFM in preschool children between the ages of 3.5 to 6 years. Six items of NPFM including 10-m shuttle run, standing long jump, balance beam walking, sit-and-reach, tennis throwing, and double-leg timed hop, were tested for 209 Chinese kindergarten children in Beijing in the morning. Intraday relative reliability was tested using intraclass correlation coefficient (ICC3,1) with a 95% confidence interval while absolute reliability was expressed in standard error of measurement (SEM) and percentage of coefficient of variation (CV%). Test sensitivity was assessed by comparing the smallest worthwhile change (SWC) with SEM, while MDC values with 95% confidence interval (MDC95) were established. Measurements in most groups, except 10-m shuttle run test (ICC3,1: 0.56 to 0.74 [moderate]) in the 3.5 to 5.5-year-old groups, balance beam test in 4- and 5-year-old (ICC3,1: 0.33 to 0.35 [poor]) and 5.5-year-old (ICC3,1 = 0.68 [moderate]) groups, and double-leg timed hop test (ICC3,1 = 0.67 [moderate]) in the 4.5-year-old group, demonstrated good to excellent relative reliability (ICC3,1: 0.77 to 0.97). The balance beam walking test showed poor absolute reliability in all the groups (SEM%: 11.76 to 22.28 and CV%: 15.40 to 24.78). Both standing long jump and sit-and-reach tests demonstrated good sensitivity (SWC > SEM) in all subjects group, boys, and girls. Pairwise comparison revealed systematic bias with significantly better performance in the second trial (p<0.01) of all the tests with moderate to large effect size.

Background: The results of sedentary time (ST) and health-related physical fitness (HPF) are not completely consistent and the studies concentrated on pre-schoolers are very limited.Methods: We measured ST and ST patterns (ST Bouts time, ST Breaks times) by accelerometer. The health-related physical fitness T-score (HPFT) was calculated by five indexes: height-weight standard score, 20 m shuttle-run test, grip strength, standing long jump and 2 × 10 m shuttle-run test.Results: We included 375 pre-schoolers (211 boys, 164 girls) in the final analysis. The total ST and ST Bouts times negatively correlated with HPFT in pre-schoolers. HPFT reduced by 1.69 and 0.70 points per 10 min increased in total ST and ST Bouts times, respectively. HPFT of the highest quartile group reduced by 9.85 points in total ST, and 10.54 points in ST Bouts time compared with the lowest quartile group. However, the HPFT increased by 0.09 points per 10 times increased in ST Breaks times; the HPFT increased by 16.21 and 15.59 points when moderate to vigorous physical activity (MVPA) replaced total ST and ST Bouts time.Conclusions: HPF negatively correlated with the Total ST and ST Bouts times, but positively correlated with ST Breaks times; and HPF significantly improved when MVPA replaced ST in pre-schoolers.

AbstractThe purpose of this study was to report sex- and age-specific physical fitness level in Polish children aged 4 to 7. 11.709 children participated in the study, including 5.684 girls and 6.025 boys aged 4 to 7 who attended kindergarten institutions throughout Poland. Physical fitness was assessed using four tests developed by Sekita including shuttle run 4 × 5 m with moving the block, standing long jump, throwing 1 kg medicine ball with two hands above the head and 20 m run. Percentile charts were developed separately for males and females using the LMS method. Boys showed higher physical fitness values than girls. In addition, an increase in the level of physical fitness was observed along with the age of the subjects. The developed reference values by age and sex in the field of physical fitness can be used for diagnostic purposes and assessing the level of physical fitness of preschool children. In addition, they can be helpful for healthcare professionals, parents and teachers to develop children’s motor activation programs and monitor their physical fitness.
