Comparison of brachial artery vasoreactivity in elite power athletes and age-matched controls.

Unlabelled: Elite endurance athletes typically have larger arteries contributing to greater skeletal muscle blood flow, oxygen and nutrient delivery and improved physical performance. Few studies have examined structural and functional properties of arteries in power athletes.

Purpose: To compare the size and vasoreactivity of the brachial artery of elite power athletes to age-matched controls.

Influence of venous function on exercise tolerance in chronic heart failure.

Purpose: The clinical phase of chronic heart failure (HF) includes a marked decline in exercise tolerance, in part due to impaired skeletal muscle blood flow delivery. Interestingly, the role of the venous system on exercise tolerance in patients with HF has not received much attention, despite evidence of changes in venous structure and function. The purpose of this study was to examine the relationship between forearm arterial and venous function, and exercise tolerance in patients with HF and age-matched controls.
