Of this study was to investigate, the effect of serum cotinine level (the metabolite of nicotine) on peripheral fatigue, repositioning accuracy of back extensors and on serum serotonin level. 60 normal males were assigned into three equal groups according to serum cotinine level, 20 non-smokers (control group) with nean age (25.2±3.83) years, mean body mass index (22.25±1.83) Kg/m2 and mean cotinine level (7.64±2.84) ng/mL, 20 moderate smokers with mean age (27.95±7.57) years, mean body mass index (22.74±1.81) Kg/m2 and mean cotinine level (30.87±13.01) ng/mL UR - http://172.23.153.220/th.pdf ER -
