Çalışmanın amacı, 8-10 yaş grubu erkek çocuklarda judo ve oyunla eğitimin çocukların fiziksel gelişimleri üzerine etkilerinin incelenmesidir. Araştırma grubunu daha önce hiçbir fiziksel egzersiz programına katılmayan toplam 44 gönüllü çocuk oluşturmuştur. Bunlardan 22'si deney grubu diğerleri ise kontrol grubudur. Deney grubuna 12 haftalık, yaş grubuna uygun olarak hazırlanan oyun ve judo teknik antrenmanları, haftada 2 gün 60 dakika uygulanmıştır. Kontrol grubu ise bu süre içinde hiçbir egzersiz programına katılmamıştır. Tüm deneklere antrenman programından önce ve program bitiminden hemen sonra olmak üzere iki kere eurofit testleri uygulanmıştır. Araştırmadan elde edilen veriler SPSS 16 paket programı yardımıyla analiz edilmiştir. Her iki grupta değerlerin karşılaştırılması ön-test, son-test değerlere bakılarak, p<0,05 anlamlılık seviyesinde T-test kullanılarak analiz edilmiştir. Egzersiz programı öncesi ve sonrasında vücut ağırlığı, boy uzunluğu, dikey sıçrama, durarak uzun atlama, pençe kuvveti (sağ el-sol el), mekik çekme, esneklik değerleri yükselerek anlamlı bir artış (p<0.05), flamingo denge değerinde anlamlı bir düşüş görülmüştür (p<0.05). Kontrol grubunda ise hiçbir parametrede anlamlı fark bulunamamıştır (p>0.05). Sonuç olarak 8-10 yaş grubu çocuklara uygulanan 12 haftalık judo teknik ve oyun antrenmanlarının çocukların fiziksel gelişimlerine pozitif katkılarının olduğu söylenebilir.

The purpose of the study was to examine the relationship between isokinetic wrist and shoulder strength and service and spike velocity of the female volleyball players. Totally 34 female volleyball players participated into the study voluntarily. Wrist (60°s-1 and 90°s-1) and shoulder strength (60°s-1 and 180°s-1) of the volleyball players were determined with isokinetic dynamometer; and service and spike velocity was determined with radar device. Pearson Correlation Analysis was performed for determining the relationship between isokinetic wrist and shoulder strength and service and spike velocity of the volleyball players. As result of the statistical analysis, whereas no significant relationship was determined between wrist and shoulder isokinetic strength and service and spike velocities of the female volleyball players (p<0,05), positive significant relationship was found between wrist and shoulder isokinetic strengths (p<0,05). Considering these results, it was possible to mention that although service and spike velocities of the volleyball players were correlational with the upper extremity strength, only wrist or only shoulder strength did not increase the velocity of service and spike, and this appeared by the effect of all upper extremity and bodily muscles. Regarding this, it was considered that volleyball players should develop other variables (strengthening all upper extremity and bodily muscles, improving the technique of spiking, etc.) besides wrist and shoulder strength in order to improve their service and spike velocity.

Today, it is known that adult obesity is a result of child and adolescent obesity. For this reason, to prevent obesity in adulthood, obesity must be controlled through organising exercise habits of adolescents in addition to organising other habits. Taking the importance of physical beauty in psychology of puberty period into consideration, the effects of aerobics exercise on the obese and fighting against obesity through exercise form the basis for our study to fight against obesity through the habit of exercise. Our study was conducted on 22 male, 27 female of high school level students through 12 weeks aerobics exercise programme, 3 days a week at least, approximately 60 minutes, interval training model. This study focuses on measurements of age, weight, gender characteristics, physical composition as anthropometric measurement (subcutaneous fat, peripheral and diametric measurement), stretching test (sit-reach test), strength test (hand dynamometer), standing long jump, vertical jump, sit-up and push-up.

The aim of the study is to investigate the effect of 8-week Nordic Hamstring (NH) exercise on hamstring/quadricepsratio (H/Q) and hamstring muscle strength. 22 amateur soccer players participated in the study. Soccer players weredivided into two groups: the control group (CG) (n = 11) who only practiced soccer training and the NordicHamstring exercise group (NHEG) (n = 11) who performed NH in addition to soccer training. The isokinetic kneemuscle strength of the soccer player was measured twice at the beginning of the study and after the 8 week NHexercise. An isokinetic dynamometer was used to determine isokinetic knee strengths of soccer players. Thedifference between pre-test and post-test results of isokinetic knee muscle strength of soccer players was determinedby Wilcoxon test. According to the results obtained, it was found that the H/Q ratio (at 180ºs-1 and 240ºs-1 angularvelocities) and hamstring muscle strength (60ºs-1, 180ºs-1 and 240ºs-1 angular velocities) increased statisticallysignificantly (p<0.05). As a result, it can be stated that NH exercise is a very important factor in achieving thedesired level of H/Q ratio, which is an important factor in increasing sportive performance and thus decreasing therisk of injury as well as increasing hamstring muscle strength.
