The Effect of Varying Cadence in Cycle Ergometry on Submaximal Predictions of Peak Oxygen Uptake
… cycle ergometry test to accurately predict peak oxygen uptake (VO2) using the standard YMCA protocol workloads. There has been limited scholarship investigating the effect that varying cadence has on trained cyclists and almost none on untrained participants. For this study twelve moderately …

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 …

Running Endurance in 27-hour Fasted Humans
… Each subject completed two exercise tests at 72% peak oxygen uptake (Vo<sub>2</sub>max), one following a 27-hour fast and one three hours after a pre-exercise meal, in random order. Fasting caused a 44.7±5.8% (±SE) decrease in endurance performance (p2(9.3±2.0%), heart rate (8.4±2.4%), rating of …

Left ventricular structure in children with developmental coordination disorder
… composition was determined using BOD POD and peak oxygen uptake (peak V02) was measured by a progressive exercise test. Height, weight and blood pressure were also measured. LVM was not significantly elevated in p-DCD compared to controls. Peak V02 was lower and SBP, BMI, HR, and BF(%) were …

CHANGES IN VE/VCO2 SLOPE OVER TIME IN LVAD RECIPIENTS
… ventricular assist devices (LVADs) recipients. Peak oxygen uptake (pVO2) and VE/VCO2 slope are key prognostic parameters, but their values after LVAD implantation and relationship with right ventricular (RV) dysfunction remain poorly understood. Methods: We conducted a multicentre study …

Assessing the anaerobic characteristics of children
… of children was examined using the accumulated oxygen deficit method (Medbo et al., 1988). In this study the maximal anaerobic capacity of children was determined from bicycle ergometer tests against constant power resistances representing 110, 130, and 150 relative percent of peak oxygen …

Aspects of fitness and physical activity patterns in Edinburgh school children
… of selected measures (20m shuttle run test, peak oxygen uptake (VO<sub>2</sub> Peak), and anthropometric measures). Thirty three children (15 boys, 18 girls) performed each test on 3 separate days. Anthropometric measures showed strong reliability (r>0.94, n=33) whilst reliability for the …

Stability-reliability and the relationship of an incremental protocol in determining peak VO2 in college-aged men and women on the StairMaster 2650 UE kayak ergometer
Measuring V02peak is an important health assessment used to indicate cardiorespiratory fitness, prescribe exercise, and diagnose heart abnormalities (2,12). Utilizing the muscles of the upper body, the new StairMaster kayak ergometer is ideal for measuring V02peak on people with lower extremity …

Aerobic Fitness, Physical Activity, and Baroreflex Senstivity in Healthy Adolescents
… was obtained via maximal exercise testing, and peak oxygen uptake (VO2peak) was determined from expired gases. Physical activity was assessed using Kriska's Modifiable Activity Questionnaire (MAQ), determining average total hours (TOT-hrs*wk-1) and average vigorous hours (VIG- hrs*wk-1) per week …

AEROBIC FITNESS AND AMBULATORY BLOOD PRESSURE IN ADOLESCENTS BORN WITH VERY LOW BIRTH WEIGHT
… ergometer to determine aerobic fitness from peak oxygen uptake (VO2 pk). On a separate day, each wore a Spacelabs 90207 ambulatory blood pressure monitor for 24 hours to determine average SBP (SBP24) and DBP (DBP24) for the 24-hour period, as well as, average SBP and DBP for wake and sleep …

The effects of water ingestion on high intensity cycling performance in a moderate ambient temperature
… 1 h familiarisation performance ride at ~85% of peak oxygen uptake (VO₂ peak) with artificially sweetened, coloured water (F). During F the cyclists drank 1.49 ± 0.14 1 (values are mean± SEM), of which 0.27 ± 0.08 1 remained in the stomach at the end of exercise and 0.20 ± 0.05 1 was urinated …

Physiological effects of exercise in patients with peripheral vascular disease
… included in the final regression model were peak oxygen uptake, calf muscle oxygenation at 1 min and time-to-minimum calf muscle oxygenation. The results suggest that cardiopulmonary fitness and the ability to match oxygen delivery to metabolic demand are important determinants of walking …

The effects of short duration, combined sprint interval training on performance measures
… for improving performance measures such as peak oxygen uptake, incremental time to exhaustion, and power output. Whilst this is beneficial, literature has focussed on the use of lower extremity SIT, despite contributions from both lower and upper extremities in sporting performance. …

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 …

Evaluation of dry-land ergometry in assessment of cardiopulmonary and metabolic responses to arm and leg exercise in swimmers.
… undertaken. The first study compared lactate and oxygen uptake responses to separate dry-land armpulling and leg-kicking in recreational (RSW) and collegiate swimmers (SW). The exercise intensity at a blood lactate concentration of 4 mmol-l" (E~) and the peak oxygen uptake (V OZpeok), peak …

Neuromuscular adaptations of either endurance or high-intensity interval training
… HDEMG motor unit variables (mean discharge rate, peak-to-peak amplitude, conduction velocity and discharge rate variability) was tested (Study 1), a new method to track the same motor units longitudinally was proposed (Study 2), and the level of low (<5Hz) and high (>5Hz) frequency motor unit …

Physiological and biomechanical responses during high intensity upper body exercise
… force production and cadence. Corrected peak power output (PPO) was independent of load (P > 0.05) and uncorrected PPO increased with load (P < 0.05). Results from EMG analysis demonstrated that all upper body sites increased EMG activity at the point of fatigue/minimum power output (PO). …
