Echocardiographic Parameters and Athlete Performance: Associations and Training Profile Comparisons.

Area of Science:

• Cardiology
• Sports Medicine
• Physiology

Background:

• Endurance athletes exhibit unique cardiac adaptations.
• Standard echocardiography may not fully capture these changes.
• Advanced echocardiographic techniques offer deeper insights into cardiac function.

Purpose of the Study:

• To investigate echocardiographic parameters in endurance athletes with varying training profiles.
• To assess the association between these parameters and exercise performance.

Main Methods:

• Advanced echocardiography and cardiopulmonary exercise testing were performed on endurance athletes.
• Athletes were categorized into Long-Distance, Mid-Distance, and Detrained groups.
• Analysis included left ventricular ejection fraction, strain parameters, and myocardial work indices.

Main Results:

• Long-Distance athletes showed higher stroke volume index and global work efficiency.
• Lower left ventricular global longitudinal strain and left atrial reservoir strain were observed in Long-Distance athletes.
• Stroke volume index and global work efficiency independently correlated with Peak VO2.

Conclusions:

• Advanced echocardiography provides valuable information on athlete's heart adaptations.
• Myocardial work indices and left atrial reservoir strain reflect training status.
• Stroke volume index and global work efficiency are associated with exercise capacity, supporting their clinical use.
