Abstract

Adipose tissue lipoprotein lipase and postheparin plasma triglyceride lipase activities were measured in 28 men differing in their physical training activity. They were divided into 4 subclasses based on their training intensity. The two most active classes (17 subjects) having regular heavy exercise at least 4 times a week were considered as the activity training group, and the other two (11 subjects) classes not training regularly as the control group. In postheparin plasma, the lipoprotein lipase activities were not different between the two groups, whereas training subjects had significantly (P < 0.02)lower hepatic lipase activities. Adipose tissue lipoprotein lipase activity was in the training group at about 70 higher level on an average than in the controls (P<0.10). A significant positive correlation (r=0,38, P < 0.05) was obtained between the adipose tissue lipoprotein lipase activity and the level of physical activity. Our data suggest that even moderate inter-group differences in the physical training activity are reflected as measureable alterations in the adipose tissue lipoprotein lipase activity in man.
