l-Citrulline supplementation improves O2 uptake kinetics and high-intensity exercise performance in humans.
The purpose of this study was to compare the effects of l-citrulline (Cit) and l-arginine (Arg) supplementation on nitric oxide (NO) biomarkers, pulmonary O2 uptake (V̇o2) kinetics, and exercise performance. In a randomized, placebo (Pla)-controlled, crossover study, 10 healthy adult men completed moderate- and severe-intensity cycling exercise on days 6 and 7 of a 7-day supplementation period w...
متن کاملOxygen Uptake Kinetics during Exercise
This thesis has investigated oxygen uptake ( i r02) kinetic regulation during whole body exercise by investigating not only the breath-by-breath V O ~ response to a change in work rate but also incorporating an examination of data analysis processes and simulation of a physiological V O ~ model. Five experiments have been completed to answer the following questions: Experiment 1: What effects d...
متن کاملOxygen uptake kinetics during exercise.
The characteristics of oxygen uptake (VO2) kinetics differ with exercise intensity. When exercise is performed at a given work rate which is below lactate threshold (LT), VO2 increases exponentially to a steady-state level. Neither the slope of the increase in VO2 with respect to work rate nor the time constant of VO2 responses has been found to be a function of work rate within this domain, in...
متن کاملEffect of creatine supplementation on oxygen uptake kinetics during submaximal cycle exercise.
The purpose of this study was to test the effect of oral creatine (Cr) supplementation on pulmonary oxygen uptake (VO(2)) kinetics during moderate [below ventilatory threshold (VT)] and heavy (above VT) submaximal cycle exercise. Nine subjects (7 men; means +/- SD: age 28 +/- 3 yr, body mass 73.2 +/- 5.6 kg, maximal VO(2) 46.4 +/- 8.0 ml. kg(-1). min(-1)) volunteered to participate in this stud...
متن کاملEffect of L-NAME on oxygen uptake kinetics during heavy-intensity exercise in the horse.
There is evidence that oxidative enzyme inertia plays a major role in limiting/setting the O(2) uptake (VO(2)) response at the transition to higher metabolic rates and also that nitric oxide (NO) competitively inhibits VO(2) within the electron transport chain. To investigate whether NO is important in setting the dynamic response of VO(2) at the onset of high-intensity (heavy-domain) running i...
