Key result
Elite cross-trained Alpine skiers had significantly larger left ventricular internal dimension in diastole, wall thickness, and left ventricular mass compared with sedentary controls (p < 0.05).
Why the study?
Does elite cross-training in Alpine skiing alter cardiac structure and function compared to sedentary controls?
Cross-Sectional (n=35)
Does elite cross-training in Alpine skiing alter cardiac structure and function compared to sedentary controls?
p-value: p=< 0.05
Elite cross-trained Alpine skiers exhibit physiological left ventricular chamber dilatation and wall enlargement compared to sedentary controls, with sex differences primarily driven by body size.

May reflect physiological LV remodeling in elite skiers; leaves open sport-specific effects of cross-training.
George et al. (1999) conducted a cross-sectional in Healthy (n=35). Elite cross-training (Alpine skiing) vs. Healthy sedentary controls was evaluated on Cardiac structure and function (LVIDd, septal and posterior wall thickness, left ventricular mass) (p=< 0.05). Elite cross-trained Alpine skiers had significantly larger left ventricular internal dimension in diastole, wall thickness, and left ventricular mass compared with sedentary controls (p < 0.05).
