The purpose of this study was to assess the validity of predicting maximal oxygen uptake [V(.-)((O)(2)(max))] from sub-maximal V(.-)((O)(2)) values elicited during perceptually regulated exercise tests of 2- and 4-min duration. Nineteen physically active men and women (age range 19-23 years) volunteered to participate in two graded exercise tests to(More)
The validity of predicting peak oxygen uptake ( $$ \dot{V}{\text{O}}_{{ 2 {\text{peak}}}} $$ ) in sedentary participants from a perceptually regulated exercise test (PRET) is limited to two cycle ergometry studies. We assessed the validity of a treadmill-based PRET. Active (n = 49; 40.7 ± 13.8 years) and sedentary (n = 26; 33.4 ± 13.2 y) participants(More)
This study assessed the relationship of the rating of perceived exertion (RPE) with heart rate and pacing strategy during competitive running races of differing distance and course elevation. Nine men and women competed in a 7-mile road race (7-MR) and the Great West Run half marathon (GWR; 13.1 miles). Heart rate, split mile time, and RPE were recorded(More)
This study assessed the relationship between the rate of change of the rating of perceived exertion (RPE), physiological activity, and time to volitional exhaustion. After completing a graded exercise test, 10 participants cycled at a constant load equating to 75% of peak oxygen uptake (V O(2)peak) to exhaustion. Participants performed two further constant(More)
Objective. To identify modifiable cardio-metabolic and lifestyle risk factors among indigenous populations from Australia (Aboriginal Australians/Torres Strait Islanders), New Zealand (Māori), and the United States (American Indians and Alaska Natives) that contribute to cardiovascular disease (CVD). Methods. National health surveys were identified where(More)
This study sought to identify any differences in peak muscle activation (EMGPEAK) or average rectified variable muscle activation (EMGARV) during supinated grip, pronated grip, neutral grip and rope pull-up exercises. Nineteen strength trained males (24.9±5y; 1.78±0.74m; 81.3±11.3kg; 22.7±2.5kgm-2) volunteered to participate in the study. Surface(More)
This study assessed the utility of the Children’s Effort Rating Table (CERT) and the Eston–Parfitt (EP) Scale in estimating peak oxygen uptake ( $$\dot{V}{\text{O}}_{{2{\text{peak}}}}$$ V ˙ O 2 peak ) in children, during cardiopulmonary exercise testing (CPET) on a treadmill. Fifty healthy children (n = 21 boys; 9.4 ± 0.9 years) completed a continuous,(More)
BACKGROUND The purpose of this study was to assess the acute effects of posture (upright vs recumbent) during moderate-intensity cycle exercise on executive function and prefrontal cortex oxygenation in young healthy adults. METHODS Seventeen physically active men (24.6 ± 4.3 years) completed 2 30-minute submaximal exercise tests (conditions: upright and(More)
Despite continued research and growing public awareness, the incidence of non-communicable diseases (NCD) continues to accelerate. While a person may have a genetic predisposition to certain NCDs, the rapidly changing epidemiology of NCDs points to the importance of environmental, social, and behavioural determinants of health. Specifically, three lifestyle(More)
