چکیده

the aim of this study was to determine the effect of resistance training for 10 weeks on muscle strength, lean body mass, serum myostatin, and insulin resistance in obese-overweight men. seventeen obsess-overweight men(age:=43.1±4.7 yr, body mass index = 29.1±2.17 kg/m2) participated in the study the subjects were randomly assigned to resistance training (n=9) and control (n=8) groups. resistance training was performed 3 times weekly for 10 weeks. body composition, metabolic parameters, and myostatin were measured prior to and after the intervention. after a 10 week resistance training, insulin resistance index (homa-ir) was significantly decreased (p0.05). also, following the resistance training, muscle strength and lean body mass were significantly increased (p

Effect of 8 week resistance training on adiponectin, Insulin resistance, insulin sensivity and HbA1c levels in overweight men

Introduction Physical activity is the most important factors of energy consumption in humans. Since energy absorption can regulated the adiponectin expression positively or negatively. Also, altering energy consumption with exercise may affect the adiponectin levels. Therefore, the present study aimed to the effect of 8 weeks resistance training on adiponectin, insulin hemostasis and HbA1c lev...

Twelve-week resistance training decreases myostatin level and improves insulin sensitivity in overweight-obese women

Myostatin is a secreted protein that acts as a potent inhibitor of skeletal muscle growth. Inactivation of myostatin increases muscle mass and decreases insulin resistance. The aim of this study was to determine if the improvement in insulin resistance after resistance training is associated with a decline in serum levels of myostatin. A sample of 19 obese-overweight women (age= 23.2±3.4 yr, bo...
