Studies dealing with the effectiveness of the Fédération Internationale de Football Association (FIFA) 11+ prevention program to improve performance outcomes in children aged < 14 years are limited. This study aimed to point out the effects of the application of short-term FIFA 11+ warm-up program on physical performance in young football players. Participants were 36 youth male football players, divided into a FIFA 11+ (n = 19; mean (SD) age: 11.15 (0.79) y) and a control group (CG: n = 17; age: 10.87 (0.8) y) and trained for 4 weeks. Before and after the training period, standing long jump performance, agility, repeated sprint ability, sit and reach, and “30–15” intermittent fitness tests were assessed. A mixed ANOVA showed significant differences between the groups in the standing long jump test (FIFA 11+: 5.6% vs. CG: −1.9%) in favor of FIFA 11+ over CG. Additionally, the FIFA 11+ performance of the Illinois agility test was significantly better compared to the CG performance (FIFA 11+: −1.9% vs. CG: 0.03%). The main findings of this study suggest that just 4 weeks of implementation of the FIFA 11+ improves physical performance compared with traditional warm-up routines in young soccer players.

Abstract Background. The purpose of the study was to realize the priorities in physical, technical and tactical training for junior football players. Moreover, preparing of the content was intended to optimize the use the most efficient methods and means for increasing the efficiency of speed and skill during the training and games. Objectives. Data were collected from 18 junior football players, with ages ranging from 14-15 years, members of the ACS Unirea (C) Tritenii de Jos team. The subjects were tested three times during the whole training stage, pre, middle and post-training examinations being performed. The three examinations consisted of 5 tests each: 50-meter sprint, standing long jump, 2000 meter running, maintaining the ball in the air and leading the ball through markers. Methods. Specific methods for developing the speed used in the study are based on repetitions (specific efforts at maximum or submaximal speed, under usual, relieved, severe conditions), on various efforts and intervals. Skill development methods took into account the complexity of coordinating action movements and the spatial, temporal, and motion force precision. For developing motor skills, the authors used the interval and circuit training. Results. All the participants attained higher levels of performance, both at the second and third examination, on each of the 5 tests. Data collected were analyzed using the One –Way ANOVA statistical procedure, which compares the results obtained by one single group of subjects. This procedure revealed, at a significant level of confidence, that the mean of the performance enhancement reached 50 percents along the one-year training stage. Conclusions. The research has shown that, by giving a more significant share of the best methods and means for developing the speed and skill in the physical training of junior footballers, the increase in the performance of these motor skills is significant.

Background: Vitamin D insufficiency is prevalent among athletes, and it can negatively affect physical performance. At the same time, most of the available data were obtained from untrained individuals of various ages, and published studies performed in athletes led to contradictory conclusions. Methods: This cohort prospective study examined the serum concentration of 25-hydroxycalciferol (25(OH)D) and its association with running speed and muscle power in 131 young football players (mean age 15.6 ± 2.4 years). Results: 25(OH)D levels were below reference in 42.8% (serum 25(OH)D <30 ng/mL) and above reference in 30.5% of the participants (serum 25(OH)D 61–130 ng/mL). A comparison of the results of 5, 15, and 30 m sprint tests and the standing long jump test found no statistically significant differences between the two groups. Athletes from the 25(OH)D-insufficient group were treated with 5000 IU cholecalciferol supplement daily for 60 days. After the treatment, the 25(OH)D concentration increased by 79.2% and was within reference in 84% of the treated athletes (serum 25(OH)D 30–60 ng/mL). Testing was repeated after the end of treatment, and a statistically significant increase in the results of the 5, 15, and 30 m sprint tests was observed (Cohen’s d was 0.46, 0.33, and 0.34, respectively), while the results of the standing long jump test remained unchanged. Body height, body weight, and lean body mass of the football players also increased. Conclusions: These findings indicate that there is likely no correlation between serum levels of 25(OH)D, muscle power, and running speed in young professional football players, and the changes observed post-treatment might have been caused by changes in the anthropometric parameters. During the study, all the anthropometric parameters changed, but the amount of lean body mass only correlated with the results of the 5 m sprint.

The aim of this study is to compare explosive strength and anaerobic power performance of taekwondo and karate athletes. 10 taekwondo and 10 karate athletes participated to the study voluntarily by taking &ldquo;Informed Consent Form&rdquo;. The athletes&rsquo; values were in taekwondo as mean of age 21&plusmn;2.4 years, height 181.2&plusmn;8.01 cm, weight 66.9&plusmn;15.74 kg, sport age 7.5&plusmn;5.52 years; in karate as mean of age 21.1&plusmn;1.66 years, height 170.2&plusmn;10.04 cm, weight 64.4&plusmn;15.69 kg, sport age 10.5&plusmn;3.83 years. Counter movement jump, standing long jump and Wingate Anaerobic Test were applied to the athletes. The data were analyzed by using statistical package program. Descriptive statistics were used for mean and standard deviation values, &ldquo;Shapiro-Wilk&rdquo; test was used to determine whether the data showed normal distribution or not and &ldquo;Independent t Test&rdquo; was used for comparisons. The results were evaluated according to &ldquo;p&lt;0.05&rdquo; significance level. According to Independent t Test&rsquo;s results of vertical and standing long jump tests, there were statistically significant differences in both vertical jump and standing long jump test averages of athletes (p&lt;0.05). In comparison Wingate anaerobic test, significant differences were found in &ldquo;Watt&rdquo; values of groups&rsquo; Peak, Average and Minimum Power (p&lt;0.05). In &ldquo;kg/Watt&rdquo; values of groups&rsquo;, differences were found statistically significant in Peak and Minimum Power (p&lt;0.05), while differences were not found significant in Average Power (p&gt;0.05). As a result, when explosive strength and anaerobic power characteristics of taekwondo and karate athletes were compared, a difference was found between the two branches. The reason for this can be said to be different competition times, training programs, training methods and physical requirements of the branches. In addition, taekwondo athletes foot techniques, karate athletes using hand techniques more than foot techniques can be listed as the reasons for this difference.

This study aimed to examine inter-limb jump asymmetries and their association with sport-specific performance in young swimmers. Thirty-eight (male, n = 19; female, n = 19) regional/national level young swimmers (age: 12.3 ± 1.2 years; height: 159.6 ± 8.2 cm; body mass: 52.5 ± 9.2 kg) participated in this study. Inter-limb asymmetries were assessed for single-leg countermovement jump (SLCMJ) and single-leg standing long jump (SLSLJ). Sport-specific performance was evaluated using front crawl (i.e., 50 m and 25 m) and front crawl kick (i.e., 50 m and 25 m). The kappa coefficient revealed a “slight” level of agreement (Κ = 0.156, 0.184, and 0.197 for female, male, and all, respectively) between the direction of asymmetry for SLCMJ and SLSLJ, indicating that asymmetries rarely favored the same limb during both tests. A paired sample t-test showed a significant difference (p = 0.025) between asymmetry scores obtained in SLCMJ and SLSLJ. No significant difference was found in asymmetry scores between males and females (p = 0.099 to 0.977). Additionally, no association between asymmetry scores and sport-specific performance was observed (p > 0.05). Our findings highlight the independent nature of inter-limb asymmetries derived from SLCMJ and SLSLJ among young male and female swimmers. Further, our results suggest no association between jumping asymmetries and sport-specific performance.

The purposes of the present study were to (1) investigate the effects of the arm movement and initial knee joint angle employed in standing long jump by the ground reaction force analysis and three-dimensional motion analysis; and (2) investigate how the jump performance of the female gender related to the body configuration. Thirty-four healthy adult females performed standing long jump on a force platform with full effort. Body segment and joint angles were analyzed by three-dimensional motion analysis system. Using kinetic and kinematic data, the trajectories on mass center of body, knee joint angle, magnitude of peak takeoff force, and impulse generation in preparing phase were calculated. Average standing long jump performances with free arm motion were +1.5 times above performance with restricted arm motion in both knee initial angles. The performances with knee 90° initial flexion were +1.2 times above performance with knee 45° initial flexion in free and restricted arm motions. Judging by trajectories of the center mass of body (COM), free arm motion improves jump distance by anterior displacement of the COM in starting position. The takeoff velocity with 90° knee initial angle was as much as 11% higher than in with 45° knee initial angle. However, the takeoff angles on the COM trajectory showed no significant differences between each other. It was found that starting jump from 90° bend knee relatively extended the time that the force is applied by the leg muscles. To compare the body configurations and the jumping scores, there were no significant correlations between jump scores and anthropometry data. The greater muscle mass or longer leg did not correlated well with the superior jumping performance.

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 sought to identify potential predictors of standing long jump (SLJ) performance using force–time strategy metrics within the unloading, eccentric yielding, eccentric braking, and concentric phases. Fifteen National Collegiate Athletic Association division 1 male soccer players (19 [1] y, 1.81 [0.94] m, 80.3 [22.4] kg) performed 3 maximum-effort SLJs, while 3-dimensional ground reaction force (GRF) data were obtained. Regularized regression models were used to investigate associations between force–time strategy metrics and 2 metrics of SLJ performance (ie, jump distance and modified reactive strength index). Jump height and eccentric yielding time were the only predictors of jump distance that also demonstrated large correlations to jump distance. Anterior–posterior unloading yank, average concentric vertical force, and concentric phase duration were the only predictors of modified reactive strength index that also demonstrated large correlations to modified reactive strength index. To maximize SLJ distance in high-level soccer athletes, human performance practitioners could design interventions to drive changes in strategy to increase jump height and decrease eccentric yielding time. To improve SLJ explosiveness, interventions to drive changes in unloading and concentric force application and decrease concentric time could be emphasized. Importantly, unique variable combinations can be targeted when training for SLJ distance and explosiveness adaptations.

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.
