The acute and chronic effects of exercise intensity and rest duration on physiological responses during 4-second sprint interval exercise
… 5-8-times higher than the power needed to elicit VO2peak. However, the %VO2peak associated with repeated submaximal power sprints (%Pmax), particularly when paired with varying rest periods, remains unknown. The aim of this study was to systematically investigate the acute physiological responses …

Prediction of Cardio-respiratory Fitness Utilizing a Modified Step Test Protocol
… Christian Association (YMCA) step test, and a VO2peak treadmill test. All subjects completed a PAR-Q, pre-screening form, and were instructed to refrain from alcohol, caffeine, exercise, and over the counter medications for 24 hours and food for 2 hours prior to the test to be eligible for the …

Physiological and perceptual responses during self-regulated exercise in children with cystic fibrosis
… in DCU. The first visit was used to determine VO2peak and to anchor the children’s OMNI RPE scale. The second visit was used to familiarise the children with the testing procedures. During the final visit children exercised for 20 min on a cycle ergometer. The exercise intensity was …

The Relationship of Resting Cardiopulmonary Function to Peak and Submaximal Cardiopulmonary Exercise Testing in Older Adults with Heart Failure
… at least 75 years old. Peak oxygen consumption (VO2peak), the minute ventilation/carbon dioxide production (VE/VCO2) slope, and the 6MWT are powerful prognostic indicators of all-cause mortality and cardiovascular-related mortality. VO2peak and the VE/VCO2 slope, obtained during CPX, have been …

The Importance of Risk Stratification and Cardiorespiratory Fitness in Pediatric Obesity
… completed a maximal treadmill test yielding VO2peak data (mlO2/kg/min). Children were stratified into three groups: (Stage 1 n=28; Stage 2 n=47; Stage 3 n=19). VO2peak was significantly lower in Stage 3 (p = 0.02) compared to Stages 1 and 2. Children were re-stratified into three groups for …

Digoxin and exercise effects on Na+,K+-ATPase isoform gene and protein expression in human skeletal muscle
… incremental cycle ergometer exercise to measure VO2peak and to determine 33, 67 and 90% VO2peak workrates. Exercise tests were performed after taking digoxin (DIG, 0.25 mg.d-1) or a placebo (CON) for 13 day (Cybex) or 14 day (cycling), in a randomised, counterbalanced, cross-over, double-blind …

Physical Function and Body Composition in Obese Women in a Clinical Weight Loss Program
… were obtained (gait speed, chair rise time, VO2peak, grip strength, and 1-RM leg press). Pearson product correlations among physical function tasks and body composition measures were examined. Gait speed was not significantly correlated with any body composition component or other physical …

The impact of carbohydrate ingestion on the regulation of fat oxidation following exercise
… exercise. Methods: Six males (age 23.4 2 1.7y, vo2peak 58.0 2 2.1 ml.kg-'.min-') participated in the study. Subjects performed an incremental maximal cycle ergometer test and a verification trial to determine the workload corresponding to 75%V02peak. On separate days, subjects exercised at 75% …

THE EFFECT OF INTERMITTENT CYCLE TRAINING TIME AND INTENSITY ON AEROBIC CAPACITY
… to reach > 80% of maximal heart rate (HRmax). VO2peak and Watt max were assessed pre and post each intervention, with a 4-6 weeks wash-out period between interventions. Results: VO2peak increased post intervention in 30HIT (37±1 to 38±1 ml.min-1.kg-1) and 60HIT (35±1 to 38±1 ml.min-1.kg-1). …

Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake
… 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 control group …

Extremely short duration high intensity training as a cardiovascular training method for front line police officers
… 173.2 ± 7.7 cm; body mass, 90.5 ± 16.6 kg; VO2peak, 37.16 ± 4.65 ml kg-1 min-1). Participants’ blood pressure, critical power and VO2peak were tested across two testing days on three occasions; at the beginning of the study, post 8 weeks control and post 8 weeks High Intensity Interval …

Chronotropic Incompetence in Patients with Heart Failure and a Preserved Ejection Fraction: Prevalence and Impact on Exercise Tolerance
… 41.8% (28/67) respectively. Further analysis of VO2peak in CI and non-CI participants revealed a significantly higher VO2peak in individuals without CI (14.5 ± 3.2 ml∙kg-1∙min-1) compared to participants with CI (12.3 ± 2.3 ml∙kg-1∙min-1). There was no significant difference in the prevalence of …

The Impact of Non-Mandated Physical Training on Physiological Measures and Performance in Army Officers
… main effect of groups was attained in body fat, VO2peak, and peak power (P< 0.05) and main effect of time was observed across all participants in VO2peak and push-up performance (P< 0.05). Plausible explanations can be due to the observed rank and limitations of the Army Physical Readiness …

The Effects of Aerobic Exercise Training on Arterial Stiffness in the Metabolic Syndrome
… pulse pressure (cPP), and peak aerobic capacity (VO2peak) between healthy subjects (n=15) and MetS individuals (n=21), free of CV events. Further, we examined how 8 weeks of aerobic exercise training in MetS individuals (n=11) altered the above parameters, compared to MetS individuals (n=9) who …
