Stability of relative oxygen pulse curve during repeated maximal cardiopulmonary testing in professional soccer players.
During cardiopulmonary exercise testing (CPET), stroke volume can be indirectly assessed by O(2) pulse profile. However, for a valid interpretation, the stability of this variable over time should be known. The objective was to analyze the stability of the O(2) pulse curve relative to body mass in elite athletes. VO(2), heart rate (HR), and relative O(2) pulse were compared at every 10% of the ...
متن کاملThe slope of the oxygen pulse curve does not depend on the maximal heart rate in elite soccer players
INTRODUCTION It is unknown whether an extremely high heart rate can affect oxygen pulse profile during progressive maximal exercise in healthy subjects. OBJECTIVE Our aim was to compare relative oxygen pulse (adjusted for body weight) curves in athletes at their maximal heart rate during treadmill cardiopulmonary exercise testing. METHODS A total of 180 elite soccer players were categorized...
متن کاملLong-term stability of the oxygen pulse curve during maximal exercise
INTRODUCTION Exercise oxygen pulse (O₂ pulse), a surrogate for stroke volume and arteriovenous oxygen difference, has emerged as an important variable obtained during cardiopulmonary exercise testing. OBJECTIVES We hypothesized that the O₂ pulse curve pattern response to a maximal cycling ramp protocol exhibits a stable linear pattern in subjects reevaluated under the same clinical conditions...
متن کاملRepeated-sprint ability in professional and amateur soccer players.
This study investigated the repeated-sprint ability (RSA) physiological responses to a standardized, high-intensity, intermittent running test (HIT), maximal oxygen uptake (VO(2) (max)) and oxygen uptake (VO(2)) kinetics in male soccer players (professional (N = 12) and amateur (N = 11)) of different playing standards. The relationships between each of these factors and RSA performance were det...
متن کاملCardiopulmonary Performance During Maximal Exercise in Soccer Players with Alterations in Renal Function
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 glomerular filtration rate (GFR) after performing the pre-season training protocol. Sixteen male professional soccer players (25 ± 3 years; 179 ± 2 cm; and 77 ± 6 kg) were evaluated for oxygen uptake (VO2), heart rate (...
