Background Preliminary evidence suggests that peak exercise oxygen pulse–peak oxygen
uptake/heart rate-, a variable obtained during maximal cardiopulmonary exercise testing …

Background Beta blockers (BB) reduce chronotropic response and exercise capacity in
heart failure with preserved ejection fraction (HFpEF). To analyze the influence of BB on …

Cardiopulmonary exercise testing (CPET), a valuable tool in medicine and sports
performance for decades, couples traditional exercising testing parameters …

This cross-sectional study compared somatic, endurance performance determinants and
heart rate variability (HRV) profiles of professional soccer players divided into different age …

Background—Conventional cardiopulmonary exercise testing can objectively measure
exercise intolerance but cannot provide comprehensive evaluation of physiology. This …

Cardiopulmonary exercise testing (CPET) guidelines recommend analysis of the oxygen
(O2) pulse for a late exercise plateau in evaluation for obstructive coronary artery disease …

Aerobic fitness and flexibility generally present age-related decreases, yet the influence of
age on these variables in soccer players is still unknown. We obtained oxygen consumption …

Background Heart failure with preserved (HFpEF), mildly reduced (HFmrEF) and reduced
(HFrEF) ejection fraction (EF) remains a controversial categorization. Whether these three …

During cardiopulmonary exercise testing (CPET), stroke volume can be indirectly assessed
by O2 pulse profile. However, for a valid interpretation, the stability of this variable over time …

The aim of this study was to evaluate the curves of cardiorespiratory variables during
cardiopulmonary exercise testing (CPET) in soccer players who had acute alterations in the …
