Cardiac remodeling indicators in adolescent athletes

Area of Science:

• Sports Medicine
• Cardiology
• Exercise Physiology

Background:

• Widely accepted that diverse sports training induce varied cardiac adaptations.
• The precise mechanisms of cardiac remodeling across different sport modalities remain incompletely understood.

Purpose of the Study:

• To investigate variations in heart morphology among athletes from different sports.
• To correlate these morphological differences with distinct training models, methods, and demands.

Main Methods:

• Echocardiographic and anthropometric assessments were conducted on basketball players (n=42), roller hockey players (n=73), judo athletes (n=28), and swimmers (n=21).
• Analysis of variance (ANOVA) was employed to compare age, body size, and echocardiographic parameters across the athlete groups.

Main Results:

• Basketball players exhibited greater height, weight, and body surface area compared to other groups.
• Judo athletes displayed smaller interventricular end-diastolic septal thickness and left ventricular posterior wall thickness than other participants.
• Swimmers had lower relative left parietal ventricular wall thickness compared to judo athletes.

Conclusions:

• Sport-specific training and competition are primary drivers of cardiac morphological changes.
• The unique dynamics and adaptive mechanisms inherent to each sport significantly influence cardiac remodeling.
