Visfatin, a novel adipokine, is increased in obesity. It is not well known whether resistance training induced change in adipose tissue and blood lipids decrease plasma visfatin; thus, the purpose of this study was to examine the effect of 8 weeks' resistance training on plasma visfatin in middle-aged men. Nineteen healthy middle-aged men (aged 39.2 ± 4.6 years; height 173.8 ± 6.5 cm; BMI 24.8 ± 2.8 kg/m 2 ; mean ± SD) participated as subjects in this study. The subjects were randomly assigned to training group (n=9) or control group (n=10). Resistance training was performed for 3 days a week at an intensity corresponding to 65-80% of one-repetition maximum, 8-12 repetitions, 2-4 sets for 8 weeks. The results showed that body fat percent, WHR and plasma visfatin were decreased (p<0.05) in the training group. Maximum oxygen consumption, on the other hand, increased signifi cantly (p<0.05) in the training group compared with the control group. Plasma visfatin levels at baseline were positively correlated (p<0.05) with body fat percent and triglyceride concentration. In conclusion, it was seen that 8 weeks resistance training induced change in adipose tissue decreased plasma visfatin in middle-aged men.

The aim of this study was to assess the prevalence of kyphosis disorders in students. Total of 502 students in three levels including primary (99 girls, 99 boys), guidance (47 girls, 57 boys) and high schools (100 girls, 100 boys) participated in this study. Frontal Cobb angle was measured by fl exi curve ruler. Data were analysed by χ 2 test. After collecting, subjects were classifi ed in four categories including fl at back, normal, kyphosis and hyperkyphosis. Of 256 boys, 2% had fl at back, 76.6% were normal and 21.4% had kyphosis and of 256 girls 4.5% showed fl at back, 80% showed fl at back normal and 15% showed kyphosis, but there were signifi cant differences between their disorders (p > 0.05). There was signifi cant difference between boys and girls in elementary school (p < 0.05). In guidance and high school boy and girls, there were significant differences between their spinal deformities (fl at back, normal and kyphosis). We concluded that reducing improper habits and familiarising the children with the proper way of carrying their bags and performing proper activities such as sitting and sleeping and also participating in regular training can reduce the risk of spinal deformities.on 30 April 2019 by guest.
