The aim of this study was to compare the effects of aerobic and combined training on endothelial response in elderly men. 21 healthy non-athlete elderly men (age range 60- 80 years old) voluntary participated in this study and were randomly allocated to three groups: aerobic training, combined training and control. Aerobic training program (walking or running with 50-60% HRmax) was performed each session 45 min., 3 sessions per week. The subjects of the combined training participated in 22 min. of resistance training with weight 3 days per week, 10-12 repetitions per session, 40-60% 1RM, 60-90 seconds rest interval as well as 22 min. of aerobic training with 50-60% HRmax. Control group did not receive any intervention. Blood samples were collected before and 48 hours after the end of the protocol in an experimental condition. Findings showed that ICAM-1 levels in aerobic training group (39.9%, P=0.02) and combined training group (45.68%, P=0.02) significantly decreased, but the difference between the gropes was not significant (P>0.05). Weight, BF%, BMI, TC and TG significantly decreased in both experimental groups (P<0.05). Finally, aerobic and combined training decreased serum ICAM-1, although this decline due to combined training may be more than aerobic training alone.

The aim of this study was to determine the effect of six weeks of high intensity interval training (HIIT) on plasma levels of cellular and vascular adhesion molecules (ICAM-1 & VCAM-1) in sedentary young men. 24 sedentary young men voluntarily participated in this study and were randomly divided into two groups: experimental (n: 12, age: 24.33±1.41 yr, height: 176.22±4.91 cm, weight: 72.27±6.59 kg) and control (n: 12, age: 23.27±2.01 yr, height: 180.22±6.88 cm, weight: 76.27±7.23 kg). Experimental group performed three HIIT sessions per week for 6 weeks. Each session consisted of four to six repeats of maximal sprint running within a 20 m area with 30 sec. recovery. Fasting blood samples were collected one day before and 48 hours after the training protocol for lab analysis. Data were analyzed by independent t test and results showed that six weeks of HIIT significantly reduced ICAM 1 (27.13%) (P=0.027) in the experimental group compared to control group and the decrease (7.15%) in VCAM-1 was not significant (P=0.32). Also, the present study showed a significant increase (8%) in VO2max and a significant decrease (15.68%) in body fat of experimental group compared to control group. Therefore, it appears that HIIT improved plasma levels of cellular and vascular adhesion molecules in sedentary young men in addition to effectively reducing body fat and increasing aerobic fitness. It seems that with regard to time effect, HIIT is an efficient factor to prevent and improve risk factors of chronic diseases such as cardiovascular diseases.
