The effect of concurrent training with supplementation of vitamin E on serum levels of adhesion molecule type 1 & lipid profile in overweight men

Intercellular adhesion molecule-1 (ICAM-1) and lipid profiles are the main factors in the occurrence of atherosclerosis and inflammatory diseases. Therefore, the purpose of current study was to investigate the effects of eight weeks of combined trainings (Resistance - Aerobic) along with vitamin E supplementation on the serum levels of ICAM-1 and lipid profiles in sedentary and overweight men.

For this purpose, 32 healthy sedentary overweight men (body mass index, 26.69 ± 0.91 kg/m2) participated in this semi experimental study and were randomly divided into four equal groups (n=8) of control, supplementation, exercise + placebo, and exercise + supplementation. Participants used 400 IU of vitamin E per day for eight weeks. Concurrent exercise (Resistance - Aerobic) was performed for eight weeks, three sessions per week. Fasting blood samples were taken pre and post of study protocol. Analysis of covariance test was used to evaluate the data at a significance level of p<0.05.

No significant intra-group changes were observed in the serum level of ICAM-1, low density lipoprotein cholestrol and triglyceride (p>0.05). Despite this, high density lipoprotein cholestrol increased significantly in the training–supplementation group (p<0.05). There was no significant inter-group difference in ICAM-1 serum levels  and lipid profile after interventions (p>0.05).

The results of current study suggested that concurrent exercise training along with vitamin E supplementation had no effect on serum ICAM-1, but it improved aerobic power in sedentary overweight men.
