OBJECTIVE This investigation explored how aerobic interval training influences central or peripheral hemodynamic response(s) to exercise in patients with heart failure (HF) with preserved ejection fraction (HFpEF) or those with HF with reduced ejection fraction (HFrEF). DESIGN One hundred twenty HF patients were divided into four groups: HFpEF and HFrEF with aerobic interval training (3-min i...

Introduction Regular endurance training induces numerous physiologic adaptations that facilitate improved exercise tolerance and physical well-being, in large part by increasing the body’s capacity to transport and utilize oxygen. In contrast, brief bouts of high-intensity, sprint-type exercise are generally thought to have less of an effect on aerobic energy metabolism. However, a growing body...

BACKGROUND In professional soccer, a significant amount of training time is used to improve players' aerobic capacity. However, it is not known whether soccer specific training fulfils the criterion of effective endurance training to improve maximal oxygen uptake, namely an exercise intensity of 90-95% of maximal heart rate in periods of three to eight minutes. OBJECTIVE To determine whether ...

BACKGROUND Improved oxygen uptake improves soccer performance as regards distance covered, involvements with the ball, and number of sprints. Large improvements in oxygen uptake have been shown using interval running. A similar physiological load arising from interval running could be obtained using the soccer ball in training. OBJECTIVES The main aim was to study physiological adaptations to...

PURPOSE This study examined the association between dominant somatotype and the effect on aerobic capacity variables of individualised aerobic interval training. METHODS Forty one white North African subjects (age 21.4+/-1.3 years; Vo2max = 52.8+/-5.7 ml kg(-1) min(-1)) performed three exercise tests 1 week apart (i) an incremental test on a cycle ergometer to determine Vo2max and Vo2 at the ...
