Resting heart rate (RHR) is positively related with mortality. Regular exercise causes a
reduction in RHR. The aim of the systematic review was to assess whether regular exercise …

Over the last 20 years, heart rate monitors (HRMs) have become a widely used training aid
for a variety of sports. The development of new HRMs has also evolved rapidly during the …

This review examines the influence on heart rate variability (HRV) indices in athletes from
training status, different types of exercise training, sex and ageing, presented from both …

The cardiac benefits of exercise have been recognized for centuries. Studies have
undisputedly shown that regular exercise is beneficial for the cardiovascular system in …

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 …

ContextLow cardiorespiratory fitness is an established risk factor for cardiovascular and total
mortality; however, mechanisms responsible for these associations are uncertain …

Purpose: To compare RR intervals and the subsequent analysis of heart rate variability
(HRV) obtained from the Polar S810 heart rate monitor (HRM)(Polar Electro Oy, Kempele …

Organisms have rhythms, such as the rhythms of the cardiac and respiratory systems,
endocrinological networks, brain circuits, awake–sleep rhythms, and so on. All these …

Numerous symptoms have been associated with the overtraining syndrome (OT), including
changes in autonomic function. Heart rate variability (HRV) provides non‐invasive data …

Purpose To assess the validity of methods for quantifying training load, fitness and fatigue in
endurance athletes using a mathematical model. Methods Seven trained runners (̇ VV˙ O 2 …
