The purpose of this study was to assess the correlation between the body composition, multiple repeated sprint ability (MRSAB) test, and vertical jump performance. Fifteen voluntary elite Turkish badminton players participated in the study. The MRSAB test consisted of 2 repetitions of 4 movements (4x3m) separated by 30 seconds of passive recovery. The best time (BT), meantime (MT), total time (TT), and fatigue index (FI) were measured. Body composition was evaluated through dual-energy X-ray absorptiometry (DEXA). Squat jump (SJ) test for explosive power and countermovement jump (CMJ) test for elastic power were used. The main findings were that there was a significant correlation between MRSAB MT and TT with lean body mass, lean arm mass, and trunk lean mass (kg) of male badminton players. However, no significant correlation was observed among MRSAB MT, BT, and TT with another total/regional body composition of female badminton players (p>0.05). Moreover, the results of male badminton players showed that there was a significant negative correlation between FI and percentage ofbody fat (%BF), percentage of leg fat (%LF), percentage of trunk fat (%TF), and trunk mass. In addition, there was a significant negative correlation between FI with %BF, body fat mass kg, percentage of arm fat (%AF), arm fat mass, and %LF of female badminton players. It was also found in the study that there was a significant correlation between SJ and %LF; CMJ and %BF, body fat mass kg, %AF, %LF and leg fat mass kg. However, no significant correlation was observed among CMJ and SJ with other total/regional body compositions of male badminton players (p>0,05). Finally, changes in body composition are important issues for the physical performance level of badminton players as regional excess body fat may cause deterioration, especially in repeated-sprint ability and jumping performance.
ÖzBu çalışmada, nitel araştırma yöntemlerinden biri olan içerik analizi kullanılmıştır. Çalışma, 220 profesyonel ve amatör badminton sporcusu ile gerçekleştirilmiştir. Veri toplama aşamasında, sporculardan badminton sporuna, ekipmanlarına yönelik metaforları ve gerekçeleri, "Badminton, Badmintoncu, Top, Raket, Müziğe, Renge......benzer. Çünkü, ......." şeklinde doldurulması istenmiştir. Elde edilen metaforlar SPSS23 programına girilerek sıklık ve yüzde analizleri yapılmıştır. Analiz sonucunda metaforlar kategorilere ayrılmıştır. Bu doğrultuda, badmintona ilişkin tenis, savaş ve hayat metaforlarının ön planda olduğu tespit edilmiştir. Bunun yanında, badmintoncu için savaşçı ve asker, badminton topu için kuş ve mermi, badminton raketi için ise kılıç ve kol metaforları ortaya çıkmıştır. Ayrıca, bir renk olarak badminton en fazla mavi, beyaz ve kırmızı metaforları ile ilişkilendirilirken, bir müzik türü olarak pop, rap ve rock ile ilişkilendirilmiştir. AbstractContent analysis was used, which is one of the qualitative research methods. " expressions.The obtained metaphors were entered into the SPSS23 program and frequency-percentage analyzes were made. Then, metaphors are divided into categories. Regarding badminton, tennis, war and life, for badminton-players warriors and soldiers, for badminton-balls birds and bullets, for badminton-racket sword and arm metaphors emerged. Besides, badminton as a colour is most associated with blue, white and red, while it is associated with pop, rap and rock as a musical genre.
Hip abductor (ABD) and adductor (ADD) muscle imbalances lead to injuries in lumbo-pelvic hip complex, and these imbalances and other factors such as foot posture might affect dynamic balance. The present study aims to examine body mass index (BMI), dynamic balance and hip muscle strength values of adolescents with different foot posture alteration. Fifty-nine healthy adolescents (mean age 12±3 years, height 156±11.46 cm, weight 50.57±11.60 kg) voluntarily participated in the study. The participants were divided into two groups according to Foot Posture Index (FPI): (Neutral Foot Group (NFG), n=48 / Prone Foot Group (PFG), n=11). The participants’ single leg – both legs dynamic balance values were measured by using balance measurement device (TOGUtm), and their hip ABD and ADD isometric muscle strengths were measured through the load cell. The dynamic balance, BMI and muscle strength values of the groups were compared by using Independent Sample t-Test. A statistically significant difference was found between the groups according to right and left single leg dynamic balance values (p<0.05). The study revealed that one of the most significant factors affecting dynamic balance in adolescents is foot posture. It is believed that using insoles suitable for the foot posture might be helpful in increasing the efficiency of dynamic movements carried out on a single leg and it is essential to suggest some exercises to correct foot postures when necessary.
Dual-tasks, which generally target motor skills and cognitive performance, also help to determine individual's postural control. The purpose of this study is to determine the changes in performance during motor tasks, which includes the cognitive cues of elite badminton athletes. Reaction time of 20 badminton athletes (male=10, female=10) were determined by The FitLight Trainer™. A significant difference was found for male badminton athletes between test protocols (p
