Key result
Prolonged endurance training in veteran cyclists resulted in proportionate left ventricular hypertrophy with preserved cardiac function, changes that appeared reversible in former cyclists.
Why the study?
Does prolonged endurance training affect cardiac structure and function in veteran cyclists compared to former cyclists and non-athletes?
Cross-Sectional
Does prolonged endurance training affect cardiac structure and function in veteran cyclists compared to former cyclists and non-athletes?
Prolonged endurance training induces proportionate, reversible left ventricular hypertrophy without reducing cardiac function in veteran athletes.
No takes yet. Share an insight, caveat, or question.
May reassure on preserved function during veteran endurance training; leaves open prospective validation of reversibility and outcomes.
Vollmer-Larsen et al. (1989) conducted a cross-sectional in Healthy subjects (veteran athletes). Prolonged endurance training (veteran cyclists) vs. Former cyclists and non-athletic subjects was evaluated on Cardiac structure and function (echocardiography, ECG, time intervals, maximal oxygen uptake). Prolonged endurance training in veteran cyclists resulted in proportionate left ventricular hypertrophy with preserved cardiac function, changes that appeared reversible in former cyclists.
