Echocardiographic dimensions and maximal oxygen uptake in elite soccer players.
OBJECTIVE To assess cardiac dimensions in elite Saudi soccer players, and to correlate these measurements with maximal oxygen uptake. METHODS Twenty-three soccer players representing the Saudi National soccer team, and 19 untrained males participated in this study. Cardiac dimensions were measured by M-mode echocardiography, and maximal oxygen uptake was assessed by open-circuit spirometry du...
متن کاملPrior moderate and heavy exercise accelerate oxygen uptake and cardiac output kinetics in endurance athletes.
Cardiorespiratory interactions at the onset of dynamic cycling exercise are modified by warm-up exercises. We tested the hypotheses that oxygen uptake (Vo(2)) and cardiac output (Q) kinetics would be accelerated at the onset of heavy and moderate cycling exercise by warm-up. Nine male endurance athletes (peak Vo(2): 60.5 +/- 3.2 ml.min(-1).kg(-1)) performed multiple rides of two different 36-mi...
متن کاملIschemic preconditioning of the muscle improves maximal exercise performance but not maximal oxygen uptake in humans.
Brief episodes of nonlethal ischemia, commonly known as "ischemic preconditioning" (IP), are protective against cell injury induced by infarction. Moreover, muscle IP has been found capable of improving exercise performance. The aim of the study was the comparison of standard exercise performances carried out in normal conditions with those carried out following IP, achieved by brief muscle isc...
متن کاملExercise modality effect on oxygen uptake off-transient kinetics at maximal oxygen uptake intensity.
NEW FINDINGS What is the central question of this study? Do the mechanical differences between swimming, rowing, running and cycling have a potential effect on the oxygen uptake (V̇O2) off-kinetics after an exercise sustained until exhaustion at 100% of maximal oxygen uptake (V̇O2max) intensity? What is the main finding and its importance? The mechanical differences between exercise modes had a p...
متن کاملCaffeine and exercise: metabolism, endurance and performance.
Caffeine is a common substance in the diets of most athletes and it is now appearing in many new products, including energy drinks, sport gels, alcoholic beverages and diet aids. It can be a powerful ergogenic aid at levels that are considerably lower than the acceptable limit of the International Olympic Committee and could be beneficial in training and in competition. Caffeine does not improv...
