Effects of Maximal Fat Oxidation Exercise Training for Body Composition and Cardiovascular Risk Factors on College...

Area of Science:

• Exercise Physiology
• Cardiovascular Health
• Obesity Research

Background:

• Cardiovascular disease (CVD) is a leading cause of mortality in China, with rising incidence and mortality rates.
• Obesity is a major CVD risk factor, and overweight/obesity rates are increasing among Chinese college students.
• Maximal fat oxidation (FATmax)-intensity training optimizes fat burning and improves cardiorespiratory and metabolic health.

Purpose of the Study:

• To investigate the effects of FATmax-intensity exercise on CVD risk factors in obese college students.
• To explore the underlying mechanisms of FATmax-intensity exercise's impact on cardiovascular health in this population.

Main Methods:

• A 12-week longitudinal study with a single-group pre-post design.
• Involved 24 obese college students undergoing FATmax-intensity training.
• Assessed body composition, biochemical markers, cardiorespiratory function, oxidative stress, and inflammatory cytokines before and after intervention.

Main Results:

• Significant reductions in body weight, BMI, body fat percentage, and abdominal fat.
• Improvements in cardiorespiratory function, including peak oxygen uptake (peak VO2) and anaerobic threshold.
• Reduced levels of inflammatory markers (ET-1, CXCR1, CXCR2, GM-CSF, IFN-γ, IL-33) and increased levels of eNOS and VEGF.

Conclusions:

• FATmax-intensity exercise improves body composition and reduces CVD risk factors in young, obese individuals.
• The training enhances oxidative stress indicators and immunomodulatory anti-inflammatory function.
• Provides a foundation for further research into FATmax-intensity exercise's effects on cardiovascular health.
