High-intensity interval training (HIIT) is frequently used in sports training. The effects on cardiorespiratory and muscle systems have led scientists to consider its application in the field of cardiovascular diseases. The objective of this review is to report the effects and interest of HIIT in patients with coronary artery disease (CAD) and heart failure (HF), as well as in persons with high...

Regular endurance training improves performance during tasks that rely mainly on aerobic energy metabolism, in large part by increasing the body’s ability to transport and utilize oxygen and by altering substrate metabolism in working skeletal muscle (Saltin & Gollnick, 1983). In contrast, highintensity “sprint”-type exercise training is generally thought to have less of an effect on oxidative ...

New federal guidelines announced in January 2005 advise adults to exercise moderately to vigorously for about an hour most days just to prevent gaining weight as they age. Those who’ve lost weight need even more activity, up to 90 minutes of moderate exercise, to keep the pounds off. Only the relatively few who have no trouble controlling their weight can meet their exercise quota in as little ...

The aim of this study was to compare the effects of high-intensity aerobic interval and repeated-sprint ability (RSA) training on aerobic and anaerobic physiological variables in male football players. Forty-two participants were randomly assigned to either the interval training group (ITG, 4 x 4 min running at 90 - 95 % of HRmax; n = 21) or repeated-sprint training group (RSG, 3 x 6 maximal sh...

t has often been demonstrated that greater improvements in key performance factors (anaerobic capacity, maximal aerobic power [MAP] and aerobic endurance) in most of the so called ‘aerobic’ sports such as cross country, middle and long distance running can be achieved through training programmes that include intermittent sessions. In fact, as shown in Table 1, when doing continuous exercise, on...

High-intensity interval training (HIIT) has become a promising strategy to induce a number of metabolic adaptations and alter body composition. Recent evidence suggests that HIIT can be a time-efficient strategy to promote health in sedentary overweight/obese individuals. This may be contrary to the belief held by some health professionals that training programs at high intensity are not approp...
