Motor Tests

The subject of this research are the motor skills of children of preschool, younger school and middle school age who train football. The aim of the study was to establish the level of correlation of the observed tests in different age categories, as well as the influence of morphological characteristics on motor test results in subjects of different age. To assess morphological characteristics: body height and body weight, and three variables - foot tapping for 15 seconds, standing long jump and 30m sprint tests were used. The study involved transversal research conducted on a sample of 40 boys of preschool, younger school and middle school age (6-13 years old), who actively played football in the "Jedinstvo" school of football from Gospodjinci. The training experience of the respondents ranges from 6 months to 5 years. The obtained results indicate that there is no statistically significant correlation between explosive strength and speed tests in preschool age, while in younger school age the statistical correlation is significant, and in middle school age the correlation is the greatest. The obtained results confirmed that the level of connection between motor tests changes depending on the age of the examinees. Body height and body weight were found to have a statistically significant effect on the results of the long jump and 30m sprint tests only in middle school age. This type of statistically significant influence of body height and body weight on the results of motor tests was not observed in preschool and younger school age.

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.

This study was conducted to examine the effect of participation in physical activity on physical fitness parameters in children aged 5-9 years. A total of 83 children, 44 girls, and 39 boys, studying in a private primary school participated in the study voluntarily. The Eurofit Test Battery was used to evaluate the physical fitness levels of children. Within the scope of the Eurofit test battery; the body weight and height values of the children were measured. In the determination of motoric performances, flamingo balance, disc touch, sit-reach, standing long jump, sit-up, bent-arm hanging, and 5x10 meter sit-up tests were used. A personal information form prepared by the researchers was used to determine demographic characteristics. Whether the data is normally distributed or not was checked with kurtosis and skewness values. In the statistical analysis dimension; descriptive analysis (mean, standard deviation, median, min-max value, ratio, frequency), independent samples t test (Independent Samples t test) were used. In terms of children having an athlete license, a significant difference was found in their height, standing long jump test, sit-up test, bent-arm hanging test, 5x10 meter sit-up run test scores (p>0.05). A significant difference was found in the findings of height, body weight, standing long jump test, sit-up test, bent arm hanging test, 5x10 meter sit-up run test in terms of children's participation in traditional children's games (p>0.05). As a result, it has been determined that children's having an athlete's license increases their height, explosive strength, core strength endurance, upper extremity strength endurance, agility, and again, the students' participation in traditional children's games has positive effect on height, body weight, explosive strength, core strength endurance, upper extremity strength endurance and agility. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0891/a.php" alt="Hit counter" /></p>

The aim of the study was to analyze if there is a connection between some anthropometric measrements and a test for assessing aerobic ability in footballers of different age categories. 65 players were subjected to these measurements, of which 25 players aged 13-14 years (pioneers); 20 players aged 15-16 years (cadets) and 20 players aged 17-18 years (juniors). By using standard anthropometric instruments, body height, body weight, median volume of the chest and aerobic endurance were measured using a 20m “shuttle run” test. Using linear regression analysis, it was found that there is no statistically significant effect of anthropometric variables on a variable (20m “shuttle run”) of all three age players. In these ages, obviously some other characteristics have more influence on the manifestation of aerobic ability. The results of the research can be used by experts in the field of sports in further planning and organizing training contents

High Level

Previous research indicates that high results in speed climbing are determined by a high level of explosive strength and muscle power in the lower limbs. However, a literature review shows that no studies have analysed women practicing this climbing discipline. Therefore, the main goal of the study was to assess the level of development of physique and the level of explosive strength and muscle power of the lower limbs of female speed climbers at a representative level. Furthermore, an attempt was made to analyse the relationships between the variables studied and race time in female speed climbers.The study included 5 female players (speed climbers) who were members of the national team in 2016. The measurements were made during the Polish National Team Camp.  The analysis was based on the results of the fastest races expressed in seconds. The measurements and indices computed in the study included body height, body weight, lean body mass, BMI and ponderal index. The assessment of the power of the lower limbs was carried out using two jump tests: CMJ with arm swing and CMJ. Power was expressed relative to body weight and to lean body mass.The highest relationships with race time were recorded for body height (r = 0.94, p <0.05), body weight (r = 0.96, p <0.01) and lean body mass (LBM) ( r = 0.98, p <0.01). Strong but statistically insignificant relationships were recorded between race time and power indicators of the lower limbs (correlations above r = -0.66).In female speed climbing, race time can be determined by the level of physique. Smaller body size can allow female climbers to perform faster and achieve better times in speed climbing. It can be suggested that in female speed climbing, a high level of maximum alactic anaerobic capacity of the lower limbs is an important factor that affects race time. The results of our own research suggest that in female speed climbing, specific body characteristics may to a greater extent determine the race time compared to anaerobic maximum power of the lower limbs.

And Performance

Introduction: Physical capabilities are an important parameter of the functional development of adolescents, not only by chronological age but also by their maturational state, as individuals with the same chronological age can have different performance to their less mature counterparts. Objective: To compare and relate the physical capabilities and hormonal markers according to sex and maturity of adolescents. Method: The sample consisted of adolescents of both sexes, aged 10 to 14 years. We evaluated the maturity achieved by a predictive equation of skeletal age, physical capabilities (explosive power of upper and lower limbs, velocity of upper limbs and agility) and hormonal markers (testosterone and oestradiol) via chemiluminescence. Results: Females showed more advanced maturational status, higher weight, body height and oestradiol levels; males performed better in the explosive force of upper and lower limbs, upper limb speed, agility and testosterone levels. In the normal maturational state males showed greater skeletal age, body weight, body height, explosive strength of upper and lower limbs, and testosterone levels; the females in the normal maturational state had higher skeletal age, body weight, body height, explosive upper limb strength and oestradiol levels. In the male correlation analysis, bone age was related to the explosive strength of upper and lower limbs and testosterone; while bone age in females was related to explosive upper limb strength and oestradiol. Conclusion: It is concluded that maturation, testosterone and oestradiol levels play an important role in the physical aspects and performance of motor skills of adolescents, especially in upper limb force which was more related to the maturation obtained by skeletal age of males and females.

The aim of our observation was to measure selected anthropometric characteristics and to analyze actual body composition in children of younger school age from elementary schools in Prague. The group consisted of a total of 222 probands, boys (n-117) and girls (n-105) aged 8–11 years (average boys age = 9.0 ± 1.0 years, body height = 139.9 ± 8.6 cm, body weight = 32 ± 7.5 kg, BMI = 16.3 ± 2.4 kg.m–2). Average age girls = 8.9 ± 0.9 years, body height = 137.3 ± 8.8 cm, body weight = 30.5 ± 7.3 kg, BMI = 15.9 ± 2.4 kg.m–2). The BIA 2000 M multi-frequency apparatus (whole-body bioimpedance analysis) was used to analyze the body composition. Children of younger school age showed higher TBW values – total body water (boys 65.5 ± 6.0%, girls 66.6 ± 6.5%), low body fat (boys 16.1 ± 2.4%, girls 16.5 ± 2.9%) and higher ECM/BCM coefficients (boys 1.0 ± 0.13, girls 1.02 ± 0.11). The authors draws, attention to the importance of monitoring other body composition parameters. The percentage of fat-free mass (FFM) and the share of segmental distribution of body fat and muscle mass on individual parts of the human body.

The Relationship

Sport climbing is now seen as part of the climbing population fi tness interesting resource. Th is study clarifi es the relationship between selected conditioning tests, anamnetic data and performance in sport climbing in the climbing trips OS or RP and each points to a relationship between these ways of ascent climbing routes. Study describes the relation between the diff erent standardized tests selected from Eurofi t test set (standing long jump, full forward trunk bend, pull-up hold, manual dynamometry, „fl amingo“ exercise), anthropometric data (body height, body weight, body fat ratio in %) and anamnestic data (length of climbing experience, climbing performance in terms Red Point RP, and On sight OS). Th e dependency measure is expressed by a linear regression with two dependent variables. Th e dependent variables express climbing performance in terms of RP and OS. Th e signifi cant indicators for dependent variable RP in this given regressive model are length of climbing experience, pull-up hold, manual dynamometry and body weight; for the dependent variable OS, these are length of climbing experience, pull-up hold and manual dynamometry. Aft er the application of a linear regression analysis with two dependent variables, the dependency measure between the RP and OS performance was formulated as a partial correlation rp = 0,745.

The aim was to establish differences in morphological characteristics of 48 selected female younger cadet (U14) handball players (age 13.88±0.46 years) in the playing positions of wings, backs and pivots. The sample of variables embraced 24 morphological measures defining the already established four latent body dimensions. Univariate ANOVA revealed the significant global differences among the three groups of U14 players in 11 morphological measures. Between the backs and pivots no significant differences were established. The greatest differences between the pivots and wings were established in body height, leg length, arm length, ankle breadth, body weight and calf circumference (p&lt;.01). The greatest differences between the wings and backs were established in four variables: body height, arm length, knee breadth and ankle breadth (p&lt;.01). We endorse the interpretation that specificities of technical-tactical activities executed by backs and pivots in attack repose in the background of the established differences, that is, backs and pivots are exposed to more body contacts in attack in which they must overcome defenders’ resistance. In the sample of the Croatian U14 female handballers apparently no somatotypic component prevailed. However, a slightly larger contribution of endomorph component was perceived in the pivots’ body composition, which was in line with the general results of the entire age group. In U14 backs both the endomorph and mesomorph component were pronounced equally, whereas all the three components were of even values in the wings

The aim of this research is to determine whether there are statistically significant differences in the anthropological status of young football players in relation to chronological age within one calendar year. The sample consisted of a total of 50 male respondents, Technical School “Mihajlo Pupin” students from the municipality of Indjija. The sample was divided into two subsamples according to chronological age (born by June 30, 2005; born July 1, 2005 and later). The students are also members of the football club in which they train. By examining the morphological characteristics, data were obtained in the following variables: body height, body mass and body mass index. Static and explosive power testing data were obtained in the following variables: standing long jump, bent arm hang and running 30 meters. It was concluded that there are no statistically significant differences between young football players of different chronological ages in anthropological status. No differences were found in the total space of tested and measured variables (MANOVA) nor in the individual space (ANOVA). The research included two anthropological spaces, morphological and motor, and none of them showed differences between young football players of different chronological ages. Out of a total of six measured and tested variables, the only variable that was on the border of the difference between the groups was running 30 meters, which may indicate that different explosive power of the lower extremities between the two tested groups, in this case, in favor of the younger group.

The Relationship

The aim of the study was to determine the relationship between jump serve velocity achieved in contact with the ball and a model height of the jump as an indicator of explosive strength of lower extremities and to correlate these values. The monitored group consisted of 169 players (n = 172, age 15.95 ± 0.75 year, body height 185.44 ± 6.9 cm, body weight 71.92 ± 7.92 kg). Before the measurement, the players undertook a jump test, when, in a model situation, they attempted to achieve maximum jump height after a run-up. The highest serve velocity value was 105.9 km.h-1, while the lowest value was 56.3 km.h-1 (difference by 46.8 %). The measured maximum values were transformed into percentile norms (50th percentile P50 = 79.9 km.h1 ). Percentile distribution for jump serve velocity and the jump enables us, with respect to a relatively high number of tested players, to consider the stated values as normative and to compare other players, as well. It appears that the correlation of jump height is a good indicator of the dispositions for jump serve implementation in terms of the ball velocity.
