The aim of this study was the investigation of basic motor skills in 5-14-year-old boys and girls.
A total of 842 primary school children, 421 boys and 421 girls, participated in the study. 13.3% of ...the participants were 5-6 years old, 29.5% were 7-8 years old, 21.5% were 9-10 years old, 16.4% were 11-12, and 19.4% were 13-14 years old. The balance skills of the participants were measured with the (Körperkoordinationstest für Kinder) KTK test.
When the classification of children according to KTK defining classes is examined, 40.7% are very good. When the children's KTK Backward Balancing scores were examined, a statistically significant difference was found between gender and age groups (
< 0.05). Girls between the ages of 5-6 and 7-8 years had a higher score for KTK backward balance. KTK Total scores were examined according to the Body Mass Index groups, when the total scores of KTK were compared, the lowest scores were in the obese group.
According to the study results, age is an essential factor for balance skills. As the age increased, the overall scores of the KTK increased. It was determined that girls' KTK backward balancing scores were higher than boys. According to BMI results, the balance performances of obese children were found to be lower than the other groups. This difference can be explained by the negative effect of obesity in this age group. According to these results, it may be recommended to observe and improve the balance performances of obese children.
Previous research has reported a strong relationship between vertical jumping, sprinting, and agility, as a reflection of lower-limb power. Unilateral analysis of this relationship has not yet been ...explored. This study primarily investigated the associations between single-leg countermovement jump (CMJ), sprint, and agility performances in youth basketball players.
Thirty-five male basketball players from the youth category (age 15.06 ± 2.62 years, n = 32 right-limb dominant; n = 3 left-limb dominant) performed single-leg CMJ, 20 m sprint, and T-drill agility tests over two sessions. Force-time-related performance variables were measured using a single-leg CMJ test on a Kistler force plate.
Significant moderate to large negative correlations were observed between single-leg CMJ variables, 20 m sprint, and T-drill agility, except for mean force for both dominant and non-dominant leg measures (r = -0.384 to -0.705). Mean power and mean force were correlated with the physical characteristics of the athletes for both legs (r = -0.389 to -0.843). Flight time and jump height were identified as the best predictor variables for both sprint and agility time in the stepwise model (R
= 0.608 to 0.660). No statistical inter-limb differences were found during the single-leg CMJ test (
> 0.05).
The study findings suggest that youth basketball players with greater single-leg jump output most likely have better sprint and agility performances. Thus, trainers and athletic performance coaches may include unilateral limb exercises in their training programs to enhance lower-limb explosive performance and reduce limb asymmetries.
Today, the participation of visually impaired individuals in sports activities is essential. Because the ability to move independently starts to develop with a delay in visually impaired individuals, ...physical activity is necessary to compensate for developmental delay, eliminate the problem of independent movement in social life by reducing obstacle perception problems, develop self-confidence, and provide regular muscle activation and motivation to move. The study investigated the effect of 6 weeks of karate (kihon) and basic movement training on balance performance in individuals with congenital visual impairment. Fifteen visually impaired individuals aged between 10 and 14 participated in the study, and three groups were formed: experiment 1, experiment 2, and the control group. After the pre-tests were taken, the experimental groups received karate and basic movement training in addition to physical education classes for 6 weeks, while the control group received only physical education classes. When the study results were examined, there were highly significant differences between the pre- and post-test values of the groups receiving karate and basic movement training. At the same time, no progress was observed in the control group. In the post-test comparison of the karate and control groups, positive significance was found in the values of the karate group. In the same way, in the post-test comparison of the basic movement training group and the control group, positive progress was made in the basic movement training group. The post-test comparison of the basic movement training and karate groups was the same. As a result, it was concluded that basic movement training and karate exercises applied for 6 weeks positively affected the balance development in visually impaired individuals aged 10-14 years. No difference was found between the exercise protocols regarding effectiveness, and no improvement was observed in individuals who did not participate in any exercise.
This study investigated the effect of a 10-week karate training program on the motor skill development of 5-7-year-old children new to karate with two different test batteries. A total of 28 ...participants were included in the study: 18 in the Karate group and 10 in the control group. The karate group was subjected to a fundamental karate training (kihon) program consisting of 90-minute sessions four days a week for ten weeks in addition to physical education classes at their schools. In contrast, the control group did not participate in any sportive activities except physical education classes in their schools. Data were collected using the Eurofit test battery and the TGMD-2 test. In the pre-post test comparison of the anthropometric measurements of the karate group, no significant difference was found in the control group. In contrast, a significant difference was obtained in height, body mass index, and body fat percentage. In the post-test analysis of the two independent groups, there were statistically significant differences in favor of the karate group regarding height and body fat percentage (
< 0.005). In the pre-post analysis of the Eurofit test and the TGMD-2 for the karate group, all parameters showed statistically significant improvements (
< 0.001), while the control group showed no statistical difference. After comparing the karate and control groups, the Eurofit Test and TGMD-2 post-test results showed significantly higher scores (statistically significant differences) in all parameters for the karate group. In conclusion, the study shows that the 10-week karate training program positively affected the motor development of the participating children.
Miller–Fisher syndrome (MFS) is an uncommon neurological disorder that is considered a variant of the Guillain–Barre syndrome (GBS). It is clinically defined by a triad of symptoms, namely ataxia, ...areflexia and ophthalmoplegia. These acute inflammatory polyradiculopathic syndromes can be triggered by viral infections, major surgery, pregnancy or vaccination. While the overall incidence of GBS is 1.2–2.3 per 100 000 per year, MFS is a relatively rare disorder. Only six cases of GBS after cardiac surgery have been reported, and to our knowledge, we describe the first case of MFS after coronary artery bypass surgery. Although cardiac surgery with cardiopulmonary bypass may increase the incidence of MFS and GBS, the pathological mechanism is unclear. Cardiac surgery may be a trigger for the immune-mediated response and may cause devastating complications. It is also important to be alert to de novo autoimmune and unexpected neurological disorders such as MFS after coronary bypass surgery.
The purpose of this study is to analyze the association between technical features such as goal, pass, shot, ball possession and ball stealing and the goals scored in matches played by teams who ...qualified out of the group (n=16) and who could not (n=8) in 2016 UEFA European Championship. The data of the study were obtained by using computerized multiple camera surveillance system (Prozone). SPSS 22.0 program was used for the statistical analyses of this study. Independent T test was used to compare the parameters of teams who qualified out of the team and those who could not, while Pearson correlation analysis was used to analyze the association between variables. When the total shot parameters per match apart from shots, total pass, total pass to the third zone and ball stealing total data were compared, significant difference was found (p<0.05). In all of the shot parameters, especially in total goals scored and total shots on target (r=0.903), a positive high association was found in total ball stealing (r=0.796), total pass (r=0.753), total forward pass (r=0.819) and total pass to the third zone (r=0.748), while a negative intermediate association was found in average pass length per match (34+M) (r=-0.449). When the results were examined, it can be said that the teams who qualified out of the game can use technical properties effectively. It can be stated that in order to be successful in elite tournaments in the world, analysis practices should be taken more into consideration as well as technical and tactical practices.
