May indicate safe cardiac adaptation in middle-aged male runners; leaves open effects on clinical outcomes.
Does an 18-week recreational marathon training program improve myocardial structure, function, and cardiovascular risk factors in middle-aged male runners?
Recreational marathon training in middle-aged men induces physiological biventricular dilation, improves diastolic function, and favorably alters cardiovascular risk factors.
