Athletes
Area of Science:
- Sports cardiology
- Exercise physiology
- Cardiac morphology
Context:
- Investigated hearts from 23 trauma-deceased athletes.
- Utilized morphometric analysis including external/internal measurements, plani- and gravimetry, histostereometry, and morpho-statistical methods.
Purpose:
- To investigate cardiac hypertrophy in athletes.
- To determine the cellular basis of exercise-induced cardiac changes.
Summary:
- All athletes exhibited hypertrophic hearts.
- Key cardiac parameters, cellular relationships, and blood supply remained within normal ranges.
- Only specific myocardial cells involved in intensified function showed hypertrophy.
Impact:
- Provides insights into physiological cardiac remodeling in athletes.
- Differentiates adaptive hypertrophy from pathological conditions.
- Contributes to understanding exercise-induced cardiac adaptations.
Abstract:
Hearts from 23 athletes who had died of traumas were investigated using a morphometric approach that involves external and internal macro-changes measurement, plani-and gravimetry, histostereometry, and morpho-statistical treatment. Hypertrophic heart was found in all the cases, while the ratios between quantitative parameters of individual heart muscle departments, as well as nuclear-cytoplasmatic and stromal-parenchymatous relationships and myocardial blood supply were within normal range. It was demonstrated that only a certain portion of myocardial muscular cells, responsible for intensified operation, became hypertrophic in response to systematic exercise.
