The purpose of this study was to investigate the effect of plyometric training on sand and wooden parquet training surfaces on the physical performance parameters of young male basketball players. Twelve well-trained young male basketball players with age 17.58±0.5 years, body mass 87.73±9.82 kg, and height 193.75±7.02 cm were voluntarily involved in the study. All participants were grouped randomly as sand and wooden training groups. A six-week plyometric training programme was performed on the sand and wooden parquet surfaces. Anthropometric measurements and physical performance tests; vertical and standing long jump, box agility, and 30m sprint tests were performed. Data were collected before and after six weeks of plyometric training and were analysed using ANCOVA. The results indicated that the plyometric training programme significantly improved jumping, agility and 30m sprint performance for both groups. Significant differences were found between the post-test mean values of two groups in the box-drill agility and 30m sprint test scores (p < .05). The results of this study suggest that while the plyometric training performed on a wooden or sand surface does not cause a different effect on the improvement of jumping performance, plyometric training on the sand surface may be a more effective training surface to improve the agility and sprint performance of young players.
Purpose: The aim of this study is to analyse the effect of relative age in anthropometric measurements, muscular strength of adolescent swimmers. Material and Methods: The study sample was composed of 40 volunteers adolescent well-trained swimmers. Participants were grouped as swimmers born in the first quarter (January, February and March) and in the last quarter (October, November and December) of the same year. Anthropometric measurements were taken from each participant, and body mass index of participants were calculated. To determine performance parameters, handgrip, back and leg strength tests were performed on participants. The level of statistical significance was set at p < .05. Results: Statistical analysis showed that there were statistically significant differences in the body height and BMI ( p < .05 ), but body weight differences were not statistically significant between swimmers who are born first and last quarter of the same year ( p > .05 ). There were significant differences in the means of absolute leg and handgrip strength between relative age groups. There were statistically significant differences in the means of relative back, leg and handgrip strength between groups ( p < .05 ). All mean relative strength values of participants significantly differed in favour of the group born in the first quarter of the year. Conclusion: As a result of this study, it is determined that relative age has an effect on the measured anthropometric and muscular strength parameters of adolescent well-trained swimmers. The findings of this study revealed that relative age is an important factor to be considered in swimming performance in adolescent swimmers.
Purpose: The purpose of this study was to determine whether there was a relationship between the digit ratios and freestyle swimming performance of adolescent well-trained swimmers. Material and Methods: Twenty-two well-trained male swimmers who had at least 3 years of swim training experience were recruited as participants. The participants’ mean age was 14.1±1.5 years, body height was 164.5±11.3 cm, and body mass was 54.4±11.2 kg. Participants’ body height, mass, index finger (2D) and ring finger (4D) lengths were measured and digit ratio (2D:4D) and body mass index of participants was calculated. To determine the swimming performance of participants, the short (50m and 100m) and middle (200m and 400m) distance freestyle time-trial swimming tests were performed on participants. The association between the 2D:4D ratio and the swimming performance were determined by the Pearson correlation coefficient. Results. Our findings indicated that there were strong negative correlations (r > .50) between the mean of BMI and swimming times of adolescent swimmers. ( p > .05 ). However, result of this study revealed no relationship between the digit ratio (2D:4D) and swimming performance in adolescent swimmers. ( p > .05 ). Conclusion. As a result, it may be stated that the 2D:4D ratio of swimmers is not a major parameter in predicting swimming performance for adolescent swimmers.

Bu çalışma, kaynaştırma öğrencileri olarak ifade edilen bireyselleştirilmiş eğitim programına (BEP) katılan öğrenciler ile akademik başarı düzeyi yüksek (ABDY) olan öğrencilerin fonksiyonel hareket analiz test bataryasında değerlendirilmesi amacıyla yapılmıştır. Çalışmaya 11-14 yaş aralığında Çanakkale İl Milli Eğitim Müdürlüğü'ne bağlı okullarda eğitim gören 30 BEP'li ve 30 ABDY'li olmak üzere toplam 60 öğrenci dâhil edilmiştir. Araştırma iki grup şeklinde tasarlanmıştır. Çalışma kapsamında antropometrik ölçümler ve fonksiyonel hareket analizi (FHA) & fonksiyonel hareket puanı testi uygulanmıştır. Grupların karşılaştırılmasında bağımsız gruplarda t testi kullanılmıştır. Anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. İstatistiksel analiz sonuçlarına göre akademik başarı düzeyi yüksek olan öğrenciler ile kaynaştırma öğrencilerinin sağ ve sol eksremite, yüksek adımlama, tek çizgide lunge, aktif düz bacak kaldırma, rotasyon stabilizesi ortalamaları arasında anlamlı bir farkın olduğu, omuz mobilitesi ortalamaları arasında ise anlamlı bir farkın olmadığı tespit edilmiştir. Gruplar arası FHA değerlerinden yüksek adımlama, tek çizgide lunge, aktif düz bacak kaldırma, rotasyon stabilitesi ve toplam FHA skoru arasında anlamlı bir farkın olduğu, derin çömelme, omuz mobilitesi ve gövde stabilitesi ortalamalarında ise anlamlı bir farkın olmadığı saptanmıştır. Sonuç olarak, bireyselleştirilmiş eğitim programına katılan öğrencilerin FHA skorlarının, akademik başarısı yüksek olan öğrencilerin FHA skorlarından daha düşük olması, bireyselleştirilmiş eğitim programına katılan öğrencilerin fiziksel kapasitelerinin akademik başarısı yüksek akranlarına göre daha düşük olduğunu ortaya koymuştur. Bireyselleştirilmiş eğitim programına katılan öğrencilere yönelik denge, koordinasyon, postüral kontrol ve hareketlilik becerilerinde gelişim sağlayan Core stabilizasyon egzersizleri çalışmaları ve büyük kas gruplarına yönelik egzersizler fonksiyonel hareket skorları üzerinde faydalı olacağı düşünülmektedir.
The aim of study is to examine the physical and psychological effects of aerobic exercises applied to mothers of children with CP. The study was conducted with 27 mothers of children with CP and diagnosed with Spastic Quadriplegia. During exercises, muscular strength, muscular endurance, flexibility and cardiac exercises were applied. The" SF-36 Quality of Life Scale" was used to obtain health-related data. In order to measure muscle strength, manual muscle test and dynamometer measurements were used. Before and after the exercises, which were held three days a week for 8 weeks, measurements were made. T-test for dependent groups was performed in order to identify the difference between measurements. According to SF-36 Quality of Life Scale, significant differences were observed in terms of the variables of physical function, physical role difficulty, pain, vitality, social functionality, mental health, emotional role difficulty, and perception of general health (p0.05). When the pretest and posttest scores obtained from the manual muscle test were compared, significant differences were determined in right arm supination, left arm supination, right arm pronation, and left arm pronation (p< 0.05). It was determined that various exercises performed had positive effects in terms of eliminating functional deficiencies, alleviating pain, socialization, and beck health in individuals who experienced problems related to physical and psychological health.
