This study aims to investigate the effect of technical competence in certain balance elements, an important parameter in rhythmic gymnastics, on sportive success in taekwondo poomsae athletes and the relationship between them. The study was conducted on 12 female taekwondo athletes (age: 17.6±1.2; height: 159.26±3.1 cm; weight: 50.79±1.82 kg; BMI: 20.88±0.98 kg/m 2 ). The participants were selected from successful athletes who were in the top 6 in their own category in the national taekwondo competition held this year. The athletes performed 6 balance elements in rhythmic gymnastics, i.e. side passé (SP), 90° forward (90°F), side split with hand support (SSWHS), Arabesque with trunk forward (A), Cossack (C) and free leg to the side (FLS), and the Y balance test. The relationship between these balances that were assessed by 3 international judges and success rating was identified using the Spearman correlation test. The level of significance was accepted as p<0.05. As result, a statistically significant difference was found between side passé and split with hand support, balances used in rhythmic gymnastics, and success ratings (p<0.05). While no statistically significant difference was found between other balances, i.e. 90° forward, arabesque with trunk forward, cossack and free leg to the side and sportive success, there was a high relationship between them. In addition, there was no statistically significant difference between sportive success and right and left anterior (RAB, LAB) posteromedial (RPMB, LPMB) and posterolateral (RPLB, LPLB) reach distances. In conclusion, since the study found a high relationship between sportive success and technical competence of poomsae athletes in the two technical side balances, it is suggested that basic gymnastics training can be effective in improving the balancing skills of taekwondo poomsae athletes.
This study was conducted to evaluate the jump performance of youth basketball players according to their sport ages. 26 male basketball players (14.1±1.6 year) who participated in the study were divided into two groups of sport ages of 4 and below (≤4) and 6 and above (≥6). The group with sports ages ≤4 consisted of 12 male basketball players with a height of 162±2.56 cm, a body weight of 51.4±3.04 kg, a body mass index of 19.4±0.74 kg/m². The other group with sports ages ≥6 consisted of 14 male basketball players with a height of 155.9±1.98 cm, a body weight of 45.7±1.85 kg, a body mass index of 18.8±0.69 kg/m. All basketball players’ squat jump (SJ) and countermovement jump (CMJ) were measured (Optojump Microgate Bolzano, Italy). The Mann Whitney U test was used to determine whether there were differences between groups in terms of T flighttimes and jump heights. Statistically significant level of p<0.05 was accepted. As a result of the study, no statistically significant difference was observed between the sport ages and SJ and CMJ splashes. In this respect, it can be considered that the Jump performance does not develop in parallel with the training age, and that the jump ability of this cause may be more related to motor skill and ability than the training age.
The purpose of this study is to examine the correlation between leg power and balance performance in elite wrestlers and injury history. In the research group, there are 18 elite freestyle male wrestlers at the ages of 24.27 ± 3.18 years, with a height of 171.86 ± 5.44 cm and a body weight of 79.27 ± 11.16 kg. Information on the injury history of the athletes’ upper legs for the past year was collected via interviews with the club’s physiotherapist. Laboratory tests to measure performance assessed height, body weight, Y balance and isokinetic leg strength. Data obtained from the study are presented as mean and standard deviation. The test of normality was carried out by the Shapiro-Wilk test. The Pearson Correlation Test was performed for all parameters with normal distribution, and significance level was accepted as p < 0.05. It was found that there is a relationship between the wrestlers’ right leg ratio and hamstring strength and injury history. However, there is no statistically significant relationship between left leg hamstring, quadriceps, ratio, right leg quadriceps, or right and left leg balance performance, and injury history. The resulting data shows that the proportioning between hamstring and quadriceps muscles in freestyle wrestlers’ upper leg strength values is not ideal. This finding provides evidence that injury risk increases with the additional impact of loss of strength.
A long and hard preparation process to improve motoric characteristics and technical requirements is needed for rhythmic gymnasts to become a competitor. Studies show that positive effects of pilates on body, resemble the effects of rhythmic gymnastics. This study is based on the idea that the preparation period for long rhythmic gymnastics training could be shortened by the support of pilates exercises. Additionally, comparing some physical, motor and physiological parameters of rhythmic gymnasts who had just started training either for rhythmic gymnastics, pilates [mat series] or combined [rhythmic gymnastics + pilates] for 8 weeks. 30 girl gymnasts whose average ages are 7,30 ± 1,41 years participated to the study. As the measurements and interpretations are based on little girls at the age of 7, all the families' approvals have been received before the study. Flamingo balance test, plate tapping, standing broad jump, sit-up test for 30 seconds, sit and reach flexibility test, bent arm hang, 10x5 m running and shuttle running test were performed pre and post training. Visual and auditory reaction and hand grip strength measurements were also included. Data analysis is conducted in SPSS 22.0 software package. Pre and posttest parameters were compared with Anova and Kruskall Wallis tests for significance and distribution of the data was tested with Shapiro-Wilk test. Significant development was observed for visual and auditory reaction, tapping plate, standing broad jump, 30 second sit-up test, sit and reach flexibility test, bent arm hang, 10×5m running in pilates training group; auditory reaction, 30sec sit-up, sit and reach flexibility in rhythmic gymnastics and pilates + rhythmic training groups. The results showed that rhythmic gymnastics training accompanied by pilates are more beneficial for the fundamental level girl gymnasts.
The aim of this study is eff ect of ballistic warm-up on isokinetic strength, balance and some parameters in male elite freestyle wrestlers. Thirteen elite freestyle wrestlers at the age of 20.15±2.11 yrs, with 174.54±7.14 cm height and 81.67±15.36 kg weight participated in the study. Measurements were performed two diff erent warm-up protocols. Running protocol at submaximal level on the treadmill for 10 minutes was applied for every wrestler. Ballistic Warm-up protocol involved 13 diff erent movements for multi-muscle groups lasting for 10 minutes. Flexibility, speed, agility, balance, hand grip and isokinetic leg strength parameters were measured. Wilcoxon Signed Rank test was performed to fi nd the diff erence between the protocols. Consequently, diff erences were found in fl exibility, right hand grip strength, right posteromedial and posterolateral balance, left posteromedial and posterolateral balance, left and right hamstring and quadriceps strength parameters. Ballistic warm-up protocol can be more eff ective in many parameters, especially strength compared to ordinary warm-up.
