The aim of this study was to analyze the relationships between cognitive functioning, physical fitness, and game performance in a sample of adolescent soccer players. Eighty-five boys from a soccer team in Rincon de la Victoria (Malaga, Spain), aged between 12 and 16 years, participated in the study. The D2 and Global-Local Attention (GLA) tests were used to evaluate selective and divided attention, respectively, and the Coding and Symbol Search tests of the Wechsler Intelligence Scale for Children (WISC-IV) were used for processing speed. To analyze physical fitness, the standing long jump test, speed test, and Course-Navette test of the Alpha-Fitness battery were used. Finally, the Game Performance Assessment Instrument (GPAI) was used to analyze sports performance in three vs. three small-sided games. The analyses showed that cognitive functioning was related to game performance. The results obtained suggest the importance of cognitive functions for performance in this sport.

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>

This retrospective epidemiological study investigated the relationship between physical fitness testing and locomotive disorder screening results among elementary school children in Japan. The test and screening results of 1033 children from a single elementary school between 2016 and 2018 were examined. Multiple regression analysis was performed for each gender of children of grades third and fourth to generate receiver-operating characteristic curves. Of the 69 children with parent-identified locomotor problems, 29 (42%) had physical fitness test score of mean ± 2 SD. For the standing long jump test in fourth grade girls, the results differed significantly ( P < .001; cut-off, 127 cm) for children whose parents did (n = 7) and did not (n = 84) suspect a possible locomotive disorder. Physical fitness testing in combination with school-based screening for locomotive disorders may be useful for identifying and accurately diagnosing these disorders in children.

Researchers and trainers are continually looking for determinants of soccer talent in the youngest and in the relationship between individual motor features relevant to this kind of sport. There is a fundamental consensus in the opinion that sprinting and jumping share a number of similar characteristics in soccer players. To the authors’ knowledge, the majority of the studies has been conducted in adult and young athletes and there has yet to be an analysis with prepubescent male players. Therefore, the purpose of this study was to investigate the relationships between the standing long jump, the three-hop test and sprint performance in prepubescent male soccer players. Material and methods. This study comprised 112 prepubescent soccer players (aged 12.08±1.79 years; height: 154.35±12.50 cm; body mass 43.69±10.28 kg). They were assessed for a 30-m linear sprint with three split sprint times, standing long jump test and three-hop test. The associations and relationships between horizontal jump performance in three-hop test and standing long jump with 0-5m, 10-m, 20-m and 30-m sprint times were investigated. Results and discussion. Correlations and linear regressions were assessed. There were weak and large associations between sprint and jump measures (r = -0.21 to -0.66; p <0.001). Linear regressions all included standing long jump as a predictor, but not three-hop test. There were no regression equations that would predict sprint times from triple hop distance that were significant. In their study of national team female athletes Agar-Newman and Klimstra, (2015) showed contradictory results. In their athletes, triple hop distance was a better predictor than standing long jump of both initial sprint speed, and maximal sprint speed. Thus, this area requires further research to better understand the mechanisms through which both sprint and jump performances are achieved in prepubescent male soccer players. Conclusion. Overall, the results of our study support the use of 30-m linear sprint and horizontal jump performance tests for prepubescent male soccer players. This research showed that sprint times correlated to horizontal jump performance in three-hop test and standing long jump tests. It showed the utility of the standing long jump test to evaluate lower limb performance between prepubescent male soccer players

Purpose: To examine the effects of loaded (LPJT) versus unloaded plyometric jump training (UPJT) programs on measures of muscle power, speed, change of direction (CoD), and kicking-distance performance in prepubertal male soccer players. Methods: Participants (N = 29) were randomly assigned to a LPJT group (n = 13; age = 13.0 [0.7] y) using weighted vests or UPJT group (n = 16; age = 13.0 [0.5] y) using body mass only. Before and after the intervention, tests for the assessment of proxies of muscle power (ie, countermovement jump, standing long jump); speed (ie, 5-, 10-, and 20-m sprint); CoD (ie, Illinois CoD test, modified 505 agility test); and kicking-distance were conducted. Data were analyzed using magnitude-based inferences. Results: Within-group analyses for the LPJT group showed large and very large improvements for 10-m sprint time (effect size [ES] = 2.00) and modified 505 CoD (ES = 2.83) tests, respectively. For the same group, moderate improvements were observed for the Illinois CoD test (ES = 0.61), 5- and 20-m sprint time test (ES = 1.00 for both the tests), countermovement jump test (ES = 1.00), and the maximal kicking-distance test (ES = 0.90). Small enhancements in the standing long jump test (ES = 0.50) were apparent. Regarding the UPJT group, small improvements were observed for all tests (ES = 0.33–0.57), except 5- and 10-m sprint time (ES = 1.00 and 0.63, respectively). Between-group analyses favored the LPJT group for the modified 505 CoD (ES = 0.61), standing long jump (ES = 0.50), and maximal kicking-distance tests (ES = 0.57), but not for the 5-m sprint time test (ES = 1.00). Only trivial between-group differences were shown for the remaining tests (ES = 0.00–0.09). Conclusion: Overall, LPJT appears to be more effective than UPJT in improving measures of muscle power, speed, CoD, and kicking-distance performance in prepubertal male soccer players.

Physical fitness, intelligence and academic achievement are being studied from a multidisciplinary perspective. In this line, studies to advance our understanding of intelligence and academic achievement could be relevant for designing school-based programs. Our study analyzed the relationship between components of physical fitness including cardiorespiratory fitness, muscular strength and flexibility and general intelligence and academic achievement in adolescents. We recruited 403 adolescents (53.6% boys) with a mean age of 13.7 ± 1.2 years from a secondary school in Spain with a medium socioeconomic status, during the 2015/2016 school year. Cardiorespiratory fitness was assessed by the 20-m shuttle run, muscular strength with the standing long jump test and flexibility with the sit-and-reach test. General intelligence was measured by both the D48 and the Raven tests. School grades were used to determine academic achievement. Linear regression analyses showed that cardiorespiratory fitness was positively associated with intelligence in both the D48 (all β ≥ 0.184, p ≤ 0.016) and the Raven tests (all β ≥ 0.183, p ≤ 0.024). Muscular strength, flexibility and overall fitness were not associated with intelligence (all β ≤ 0.122, p ≥ 0.139). Cardiorespiratory fitness, muscular strength and flexibility were positively associated with academic achievement (all β ≥ 0.089, p ≤ 0.038), except muscular strength, which was not significantly associated with Spanish language or mathematics, (all β ≤ 0.050, p ≥ 0.200). Overall, cardiorespiratory fitness was positively associated with intelligence and academic achievement.

Purpose:The number of familiarization sessions in fitness assessments seems to be critical and inconsistent. Therefore, the primary aim of this research was to determine the number of familiarization attempts that stabilize the results in particular physical fitness tests. The secondary aim was to establish the test reliability through familiarization sessions.Methods:Thirty-nine primary school children participated in this research (age: 10.8 years, body mass: 40.6 ± 8.9 kg, and body height: 145.3 ± 7.2 cm). During six sessions, with one session every third day, participants performed the following tests to assess explosive strength (vertical jump and standing long jump), coordination (polygon backward and polygon with turn) and flexibility (toe touch).Results:The results of repeated analysis of variance (ANOVA) showed that there were significant increases (p < .05) in the polygon backward and polygon with turn performances from the first to third familiarization session. The standard error of measurement decreased as sessions progressed, indicating little within subject variation between the coordination test results following a familiarization period. Statistically significant differences were identified in the vertical jump test from the fourth test session compared with the first session. On the other hand, statistically significant differences for the standing long jump test were only found in the final session compared with the initial session. In the toe touch test, there were no significant increases from the first to the final familiarization session. All tests showed high a reliability coefficients, ranging from 0.979 to 0.991.Conclusion:Polygon backward and polygon with turn performance may be a practical, reliable method to assess coordination in primary school-aged children. However, completion of at least 3 practice sessions is suggested for participants to obtain a stable score. In addition, both jump tests are feasible for assessing skill-related fitness in young children, although the scientific reliability of the two tests should be questioned and the tests should be tailored to fit the age group of the children.

Introduction. In the changes occurring in competitive sport, proper choice and selection for sport and the age of starting the training are of great importance. Aim. Determining the magnitude of changes in physical fitness and physical development of first-grade children practicing swimming in relation to the non-training peers. Material and methods. The study included two groups of children - the first one was a children practicing swimming (26 boys and 23 girls) and the second one was a non-training class (26 boys and 23 girls). In both groups, MTSF trials were conducted in September and June. The results of the study focused on three aspects: the evaluation of sexual dimorphism, the identification of differences and their direction between groups and sex. Results. There were no statistically significant differences in physical development among children who practiced swimming. There were statistically significant differences in body heights in the non-training group - only in the first study (boys – 120.30; girls – 117.86) also in body weight in the first study (boys – 24.57; girls – 21.22) and also in the second study (boys – 26,80; girls – 22,83). In the assessment of physical fitness, in the group of children training swimming, sexual dimorphism was found in: standing long jump (only in the first study boys – 151,65, girls – 134,96); hand strength measurement (only in the first study boys – 23.5; girls – 19,36); bent arm hang, both in the first study (boys – 13,40; girls – 7,70) and also in the second study (ch-14,46; dz-6,31); forward stretches (only in the first study boys – 5; girls – 1.34); 4x10m run both in the first study (boys – 14,54; girls – 15,23) and also in the second study (boys – 13,66; girls – 15,11). Whereas, in the control group in: standing long jump (also only in the first study boys – 107.78; hand strength measurement in both the first study (boys – 18,95; girls – 12,26) as in the second study (boys – 12,09; girls – 12,77); bent arm hang (only in the first study (boys – 8.21; girls – 3.02); forward stretches in both the first (boys – 2,43; girls – 1,30) as in the second study (boys – 3,30; girls – 2,19). Conclusions. In both groups, boys as well as girls reported statistically significant changes in physical development, which is a normal symptom of growth, but only in the group of girls a statistically significant increase in BMI occured. In evaluating swimming training and its effect on fitness, it can be stated that the boys were positively influenced by such tests as (bent arm hang and sit-ups) and negatively by 50 m and 600 m run. On the other hand, among girls: positive only in the sit-ups test, and negative, as in the group of boys in at 50 m and 600 m run. In the group of girls, it was also noted that the trainees, despite the fact that in the first study achieved a significantly better result in the bent arm hang test, in the second attempt they obtained a considerably weaker result, while the non-training girls in the second measurement achieved a statistically better result than the first one.

<p class="apa">The purpose of this study was to determine the effect of core training program on speed, acceleration, vertical jump, and standing long jump in female soccer players. A total of 40 female soccer players volunteered to participate in this study. They were divided randomly into 1 of 2 groups: core training group (CTG; n = 20) and control group (CG; n = 20). The mean (SD) age was 19.05 ± 1.15 years, height was 160.60 ± 4.22 cm, weight was 56.45 ± 3.33 kg, and sport age was 4.50 ± 1.24 for the core training group; the mean (SD) age was 18.55 ± 0.76 years, height was 159.10 ± 3.86 cm, weight was 52.20 ± 3.60 kg, and sport age was 3.35 ± 0.75 years for the control group. Following randomization, the 2 groups did not differ significantly (p&gt;0.05) in any of the dependent variables. The subjects in the control group did not participate in the training and participated only in the pre- and posttest measurements. To evaluate the effect of core training over the functional performance, we applied a testing procedure that included measurements of speed, acceleration, vertical jump, and standing long jump. The core training group showed a 3.4%, 5.9%, 13.3%, 4.2% improvement in speed, acceleration, vertical jump, and standing long jump (respectively) (P&lt;0.05), whereas the control group did not change (P&gt;0.05). In conclusion, Core exercises were improved speed, acceleration, vertical jump, and standing long jump in 18-19 years-old female soccer players. Therefore, it is believed core training is necessary for optimal sport performance and should not be dismissed for all sport branches.</p>

The major purpose of this study was to examine the effects of a jump rope-based physical activity afterschool program on middle school students’ physical fitness. Sixty students (Mage = 13.37, SD = 0.58; 53.3% female) participated in a 12-week jump rope-based afterschool program (45 min/time, three times/week). Participants were randomly assigned to three groups: (a) freestyle rope skipping (N = 20), traditional jump rope (N = 20), and a control group (N = 20). Physical fitness tests, including muscular strength (standing long jump, right-hand grip, and left-hand grip), flexibility, body composition, and bone mineral density (BMD) were measured in pre- and post-tests. A 2 (time) × 3 (groups) repeated measure multivariate analysis of variance (MANOVA) was performed. The results found significant improvements in muscular strength (standing long jump, right-hand grip, and left-hand grip) in both intervention groups (p < 0.001; ds = 0.2–0.44). Only the freestyle rope skipping group had increased BMD (p < 0.05, d = 0.33). Compared to the traditional jump rope, the freestyle rope skipping group showed significantly higher improvement in flexibility (p < 0.05, d = 0.83). These findings suggest that the jump rope-based afterschool program with freestyle rope skipping would be more effective than traditional jump rope to promote physical fitness performance among adolescents.
