Background:
Regular physical exercise shows significant health-related benefits, potentially through the modulation of lipid metabolism in an intensity-dependent manner.
Methods:
In this study, we profiled 794 plasma lipid species across 18 subclasses following a 24-week supervised concurrent and randomised exercise intervention at moderate and vigorous intensities in 101 young, sedentary adults.
Findings:
Here, we demonstrate that moderate-intensity exercise, but not vigorous-intensity, significantly increased plasma levels of glycerophospholipids and triacylglycerol species. Interestingly, we also identified a sex-specific response to moderate-intensity exercise, with men exhibiting elevated glycerophospholipids and lysophospholipids species, and women showing significant increases in triacylglycerols species. Increments in glycerophospholipids species were associated with improvements in cardiorespiratory fitness, i.e., VO2peak.
Interpretation:
Importantly, while traditional lipid markers, including total cholesterol or triglycerides remained unchanged after the exercise intervention, our findings suggest that exercise partially exerts its health benefits by selectively targeting and modifying specific lipid subtypes in an intensity, sex-dependent manner.

01:20Exercise 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...

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.
