Fluorescence staining and semi-quantitative image analysis of drug eluting stents

To examine the effects of vigorous physical activity (PA) on intra-abdominal fat (IF) levels in obese men.Thirty-seven obese men (mean age: 47.6 ± 8.6 years) engaged in a 12-week aerobic exercise program on a regular basis (3 days/week). We divided them into low volume of vigorous PA group (n = 19) or high volume of vigorous PA group (n = 18), based on the median time spent (34.3 min/week) in vigorous PA (over 6.1 metabolic equivalents assessed by a single-axis accelerometer) throughout the program.Regular exercise reduced IF levels (measured by computed tomography) from 188.1 ± 53.9 cm2 to 170.3 ± 46.6 cm2 for the low volume of vigorous PA group and from 167.9 ± 44.3 cm2 to 137.9 ± 40.6 cm2 for the high volume of vigorous PA group. Two-way (time × group) ANOVA revealed no significant interactions for the IF level. However, correlation analysis for all participants showed that time spent in vigorous PA throughout the program significantly correlated to IF reductions after adjusting for initial levels of IF, vigorous PA and weight changes (r = −0.42, P = 0.02).This study suggests that vigorous PA may affect IF reductions in obese men.
