This study assessed whether the accuracy of predicting maximal oxygen uptake $$(\dot{V}\hbox{O}_2\hbox{max})$$ from sub-maximal heart rate (HR) and ratings of perceived exertion (RPE) values was moderated by gender and habitual activity. In total, 27 men and 18 women completed two GXTs to determine $$\dot{V}\hbox{O}_2\hbox{max},$$ and three(More)
The purpose of this study was to assess the validity of predicting maximal oxygen uptake ( $$\dot{V}\rm O_2$$ max) from sub-maximal $$\dot{V}\rm O_2$$ 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(More)
This study assessed the relationship between differentiated ratings of perceived exertion (RPE) and heart rate with oxygen uptake $$({\dot{\hbox{V}}}\hbox{O}_{2})$$ during two graded exercise tests (GXT) to exhaustion on a cycle ergometer in 49 men and women (19–50 years) of high and low fitness. The study also assessed whether sub-maximal RPE values(More)
The pathology of cardiovascular disease (CVD) is complex; multiple biological pathways have been implicated, including, but not limited to, inflammation and oxidative stress. Biomarkers of inflammation and oxidative stress may serve to help identify patients at risk for CVD, to monitor the efficacy of treatments, and to develop new pharmacological tools.(More)
This study assessed the effect of distance feedback on athletic performance, physiological and perceptual markers and the pacing strategies utilized during treadmill exercise. Thirteen men completed four self-paced 6 km treadmill time trials with either accurate, inaccurate or no distance feedback (NF). Inaccurate time trials involved participants receiving(More)
OBJECTIVE To investigate the strength of the relationship between ratings of perceived exertion (RPE) and oxygen uptake (Vo(2)), heart rate, ventilation (Ve) and power output (PO) during an arm-crank ramped exercise test to volitional exhaustion in men and women who differed in physical status. DESIGN Each participant completed an arm-crank ramp exercise(More)
UNLABELLED Protein-leucine ingestion after strenuous endurance exercise accentuates muscle protein synthesis and improves recovery of muscle performance. PURPOSE The objective of this study is to determine whether a low-dose protein-leucine blend ingested after endurance exercise enhances skeletal muscle myofibrillar protein fractional synthetic rate(More)
Flow-mediated dilation (FMD) is the standard tool used to assess endothelial function. The premise behind the standard FMD test is that it serves as an endothelial-dependant nitric oxide bioassay; however, the endothelium may release additional dilatory molecules which contribute to FMD, most notably prostacyclin and endothelial-derived hyperpolarizing(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 utility of a single, continuous exercise protocol in facilitating accurate estimates of maximal oxygen uptake ( $$ \dot{V} {\text{O}}_{ 2} $$ max) from submaximal heart rate (HR) and the ratings of perceived exertion (RPE) in healthy, low-fit women, during cycle ergometry. Eleven women estimated their RPE during a continuous test (1(More)
