Regular exercise, including aerobic and resistance training, improves cardiorespiratory fitness and muscular strength, significantly reducing cardiovascular disease risks by improving cholesterol levels and lowering PCSK-9 expression.
Area of Science:
- Cardiology
- Exercise Physiology
- Metabolic Health
Background:
- Cardiovascular diseases (CVD) are a leading global cause of death, exacerbated by sedentary lifestyles.
- Dyslipidemia (DLD), hypertension, and diabetes are key CVD risk factors.
- Dyslipidemia promotes atherosclerotic plaque formation, and lipoproteins (Lp) can destabilize plaques, leading to CVD events.
Purpose of the Study:
- To investigate the impact of exercise training on CVD risk factors.
- To evaluate the combined benefits of aerobic ET (aET) and resistance ET (rET) on dyslipidemia and cardiorespiratory fitness (CRF) and muscular strength (MusS).
- To highlight the role of exercise in managing lipoproteins and PCSK-9 expression.
Main Methods:
- Review of existing literature on exercise training modalities and their effects on CVD risk factors.
- Analysis of studies examining aerobic ET (aET) and resistance ET (rET) independently and in combination.
- Assessment of changes in cardiorespiratory fitness (CRF), muscular strength (MusS), lipoprotein levels, and PCSK-9 expression.
Main Results:
- Both aET and rET independently improve CRF and MusS, respectively.
- Combined aET and rET demonstrate more significant improvements in cholesterol levels and reduced CVD-related mortality compared to either modality alone.
- Physical activity, particularly when associated with weight loss, reduces adiposity and mitigates inflammatory processes linked to atherosclerosis.
Conclusions:
- Promoting both aET and rET is crucial for managing dyslipidemia and reducing cardiovascular disease risks.
- Combined exercise approaches offer superior benefits for cholesterol management and mortality reduction.
- Weight loss in conjunction with exercise further attenuates atherosclerosis-related inflammation and risk.

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...

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

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...
