Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake
… THV was a strong, independent predictor of peak oxygen uptake (VO2peak). Males had a larger left ventricular mass (LVM) normalized to THV when compared to females of similar fitness level. In Paper II, THV in relation to VO2peak was compared between 31 patients diagnosed with heart failure and a …

Beyond the VO2max plateau a new approach for measuring maximal oxygen uptake
Maximal oxygen consumption (VO2max) is typically defined by the presence of the "plateau phenomenon" during incremental exercise tests, in which O2 consumption levels-off in spite of increases in workload. This is thought to reflect a limitation in the capacity of the heart to pump O2 enriched …

A comparison of maximal oxygen uptake achieved from a horizontal and inclined treadmill test
The purpose of this study was to compare two protocols and the resulting VO2 max obtained. In one protocol grade only was used to impose greater workloads; in the other protocol speed only was used to impose greater workloads. In addition, maximum heart rate, perceived general fatigue, leg fatigue …

Cardiac Structure and Function in Young Athletes
… on an isokinetic dynamometer. The relative peak oxygen uptake (VO2max ml/kg/min) was significantly higher (p < 0.05) in the endurance group (54.4 +/- 1.8) than the control group (45.8 +/- 1.6). The mean trial time was significantly longer in the endurance group (12.9 +/- 0.7 minutes) than the …

Oxygen Uptake Kinetics in Severe Intensity Exercise
… of this study was to describe mathematically the oxygen uptake kinetics during cycle ergometry, and to examine the effect of intensity on the kinetic responses within the severe domain. Sixteen volunteers performed a series of exercise tests at a range of intensities selected to elicit fatigue in …

Examining Sex Differences in Substrate Utilization During Threshold-Based Exercise Prescription
… (TRAD) of prescribing exercise (e.g. % of maximal oxygen uptake [%VO2max]) elicits sex specific amounts of metabolic stress and ratios of carbohydrate to fat oxidation that result in a lower steady-state respiratory exchange ratio (RER) in females. Differences in exercise response may be …

Specificità dei test cardio-polmonari nel nuoto: comparazione tra il nuoto trattenuto e test aspecifici di laboratorio
The purpose of this study is to compare maximal oxygen uptake (VO 2max), maximal heart rate (HRmax), and anaerobic threshold (AT) obtained by a swimming test (SW) and three other testing procedures: cycling (CY), running (RU), and arm cranking (AC). On separate day and randomly assigned, 12 male …

Efeitos da CPAP na duração do exercício e nas variáveis ventilatórias em indivíduos saudáveis
… presence of a commercial CPAP during a graded maximal test, under either negative (CPAPn, n=7) or positive (CPAPp, n=7) expectations induced by the instructions, would affect physical performance of healthy men comparing to a control group (n=9) and to a prior visit without CPAP interventions …

The impact of heat acclimation on physiological response to exercise and performance at hot and temperate conditions
… include increased sweat rate, improved maximal oxygen uptake, lowered resting and exercising core temperatures and heart rate in the heat. It is argued that these adaptations can also promote an ergogenic effect. The aim of this study is to analyse the effectiveness of a 3-week …

Comparison of selected physiological performance variables between compliers and drop outs in a supervised exercise program
… and again after six months of participation: maximal oxygen uptake, resting heart rate, resting blood pressure, serum cholesterol and body weight. U sing analysis of variance for paired groups, the three groups were found not to differ on any performance variable at entry (p > .05). No …

12-DAY ADVENTURE RUN-HIKE TRAINING AT ALTITUDE IMPROVES SEA LEVEL 5KM PERFORMANCE
… individuals (2 females) volunteered. TT, maximal oxygen uptake (VO<sub>2</sub>max), running economy (RE), and a complete blood count (CBC) were measured at SL before and after ALT. Natural ALT exposure occurred in Colorado where runners engaged in low-moderate intensity trail runs for 12 …

The Effects of High Intensity Intermittent Exercise in Normobaric Hypoxia on Aerobic Capacity and Body Composition in Overweight and Obese Sedentary Adults
… had a multiplicative effect on body composition, maximal oxygen uptake (VO<sub>2max</sub>), and resting energy expenditure (REE) in overweight and obese sedentary adults. Twelve participates were recruited for the study. Participants were randomly assigned to either a hypoxic training (HT) group …

The Effect of a Bcaa Supplement with and without Cho on Performance in Recreationally Trained Cyclists
… from the GSU cycling team (n=6). Each subject's maximal oxygen uptake (VO2 max) was determined on an electrically braked cycle ergometer using a graded exercise test. In a randomized, double-blind, crossover design, subjects received one of three supplements prior to exercise: BCAA-1 teaspoon …

The interactive effects of genetics and cardiorespiratory fitness level on cognitive performance in healthy older adults
… primary measure of cardiorespiratory fitness was maximal oxygen uptake (VO2) and neuropsychological assessments were collected either through computer-based or paper-and-pencil methods. Overall, results suggest that genetic status did interact with cardiorespiratory fitness level to influence both …

Cardiorespiratory Influences on Executive Control Function
… that stressed speed and accuracy. A graded maximal exercise test (GXT) was used to measure cardiorespiratory fitness by assessing maximal oxygen uptake (VO2max). The error-related negativity (ERN), error positivity (Pe), and inhibitory N2 components, as well as behavioral measures of …

Factors determining 200-m kayak performance: Muscle strength, aerobic capacity, stroke kinematics and training
… s). Whilst upper body strength and whole-body maximal oxygen uptake have been associated with faster race times in sub-elite athletes, it is not known whether strength and aerobic capacity, or changes in them, influence performances in high-level kayak athletes. In Study 1 of the present …

The adaptive response of humans to exercise: Impact of exercise intensity, fibre-type specific responses and molecular patterns of response
… had no effect on the magnitude of increase in maximal oxygen uptake in young healthy participants, but similar adaptations were achieved with lower training doses following high intensity training. Project # 2 determined the acute molecular response, and training-induced adaptations in aerobic …

Improving the Accuracy of the VO2 max Prediction Obtained from Submaxial YMCA Testing
Maximal oxygen uptake (VO2 max) is the best criterion measure for aerobic fitness and the prescription of exercise intensity for programs designed to enhance cardiorespiratory fitness. There are two ways of obtaining VO2 max: maximal tests, which require subjects to exercise to the point of …
