The Olympic biathlon is a very demanding physical event that requires high oxygen delivery,
good cross‐country skiing skills and skilful use of a rifle. Like all high‐performance …

We evaluated carotid-cardiac baroreflex responses in eight normotensive men (25-41 yr) on
two different test days, each separated by at least 1 wk. On one day, baroreflex response …

Purpose We aimed to evaluate in a longitudinal study the effect of intensive training on
cardiac autonomic control in athletes using 24-h heart rate variability analysis. Methods …

Endurance training decreases resting and submaximal heart rate, while maximum heart rate
may decrease slightly or remain unchanged after training. The effect of endurance training …

The effects of steady state exercise on the power spectrum of heart rate variability were
studied in 19 healthy subjects. Continuous ECG signals were recorded during 1) 15 min of …

The objective of this brief review is to discuss current hypotheses describing the roles of the
arterial baroreflex and reflexes originating from afferents within the active skeletal muscle …

Autonomic nervous alterations have generally been held responsible for the bradycardia of
the endurance athlete. In order to determine whether there is also a non‐autonomic …

Nineteen males (aged 45–68 yr) were studied before and after either a period of regular
endurance exercise [walk/jog 3–4 days/wk for 30+/-1 (SE) wk, n= 11] or unchanged physical …

Objective: This study addresses the long term and short term effects of heavy dynamic
exercise on neural control of heart rate. Methods: A group of healthy controls was compared …

The occurrence of a sustained vasodilation and hypotension after acute, dynamic exercise
suggests that exercise may alter arterial baroreflex mechanisms. Therefore, we assessed …
