Aim:
Enhancement of lipoprotein lipase (LPL) activity through drug administration has been shown to increase pre-heparin serum LPL concentrations; however, pre-heparin serum LPL responses to exercise training have not been determined. The present study was undertaken to investigate the effects of 12 weeks of supervised aerobic exercise training on pre-heparin serum LPL concentrations in overweight/obese men.
Methods:
Fifteen overweight/obese middle-aged men were assigned to one of two 12-week supervised exercise interventions: a walking group (eight participants gradually increasing brisk walking to 60 min/day 3 days a week) or a jogging group (seven participants gradually increasing jogging to 60 min/day 3 days a week). All participants maintained ad libitum diets. Blood samples were collected at baseline and immediately after 12 weeks. The primary outcome was pre-heparin serum LPL.
Results:
Pre-heparin serum LPL concentrations were increased in the jogging group after 12 weeks compared with the baseline values (mean+/-SEM: 37.6+/-4.7 vs. 51.0+/-6.6 ng/mL, respectively, p= 0.033). In the walking group, pre-heparin serum LPL concentrations remained unchanged after 12 weeks.
Conclusions:
This study demonstrates that 12 weeks of jogging training increases pre-heparin serum LPL concentrations in overweight/obese middle-aged men.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
