Spor yapanlar ile spor yapmayanların izokinetik kas kuvvetleri ile kemik yoğunluğu arasındaki ilişkinin değerlendirilmesi

Bu çalışmanın amacı; spor yapanlar ile spor yapmayanların izokinetik kas kuvvetleri ile kemik yoğunluğu arasındaki ilişkinin değerlendirilmesi ve egzersiz yapmanın önemini ortaya koymaktır. Basketbol ve Futbol branşlarında aktif spor yapan 20–25 yaşlar arasında 40 sporcu ile spor yapmayan 20–25 yaş arası sağlıklı 20 kişi üzerinde gerçekleştirilmiştir. Bu amaçla, çalışmaya katılan kişilerin ön hazırlıkları tespit edilerek demografik bulguları, izokinetik kas kuvvetleri(820–130 model Biodex 3 system izokinetik egzersiz ölçüm cihazı) ve Femur Nec (femur boynu) (Hologic QDR 4500C Fan Beam X-Ray Bone Densitometer (DEXA) kemik ölçüm cihazı) kemik yoğunluğu ölçümleri alınmıştır. Vücut Ağırlığı ve kemik yoğunluğu (Femur Nec[gr/cm2]) yönüyle yapılan değerlendirmelerde ise Kontrol ve Deneme Grupları arasında istatistiksel açıdan önemli farklılıklar görülmüştür (P

Eveluation of the relationship between bone density and isokinetic muscle strength of the people who make sports and do not make

The purpose of this paper is the evaluation of the relationship between bone density and isokinetic muscle strength of the people who make sports and who dont make and put forward the importance of making exercise. It is executed with 40 sportsmen who are between 20-25 and make active sports in the branches of football and basketball and 20 healty people between 20-25 and do not make sports. With this purpose, demographic, isokinetic muscle strenght (820–130 Biodex 3 system isokinetic exercise) and femur nec bone density (Hologic QDR 4500C Fan Beam X-Ray Bone Densitometer [DEXA]) measuraments of people who joined this study are taken by fixing their preparations. Evaluations carried out in terms of body weight and bone density (femur nec [gr/cm2]) proved that there are important differences between control and test group by statistical aspect (P<0.001). In terms of $60^ \circ$/sc, $180^ \circ$/sc and $240^ \circ$/sc right extension isokinetic muscle strenght, it is determined that footballl and basketball groups are higher than control group (P<0.001). When we examine the results of $60^ \circ$/sc right flexion isokinetic muscle strength, football group is higher than basketball and control groups at the same time it is determinet that there are similarities between basketball group and control gorup (P<0.01). In terms of $60^ \circ$/sc, $180^ \circ$/sc and $240^ \circ$/sc left extension isokinetic muscle strength, it is determined that basketball and football groups are higher than cantrol group (P<0.001). In $60^ \circ$/sc, $180^ \circ$/sc and $240^ \circ$/sc right extension basketball group, it is determined corelation at the high level in the rate of bone density this studys findings proved the relationship between isokinetic muscle strength and bone density.
