Prolonged exercise induces cardiovascular drift, which is characterized by decreasing mean
arterial pressure (MAP), stroke volume and heart rate increase. Cardiovascular drift has …

Exercise intensity can be prescribed using a variety of indices, such as rating of perceived
exertion, heart rate, levels of absolute intensity (eg, metabolic equivalents), and levels of …

Background Quantification of movement intensity and energy utilization, together with
frequency of trips, duration, distance, step counts and cadence, is essential for interpreting …

Background The percentages of heart rate (% HRR) or oxygen uptake (% V̇O 2 R) reserve
are used interchangeably for prescribing aerobic exercise intensity due to their assumed 1 …

Aim Compared to other modulators of physiological strain associated with exercise heat
stress, hyperthermia results in the greatest magnitude of cardiovascular (CV) drift and …

Methods 7 active men (mean±SD; age= 25±6 yr, percent body fat= 11.9%±2.4%) completed
a control graded exercise test (GXT) on a cycle ergometer and treadmill. Then on separate …

Purpose Studies indicate that the rated perceived exertion (RPE) during physical exercise
can be lower in field environments than indoors. The environmental conditions of those …

Background Rating of perceived exertion (RPE) is considered a valid method for prescribing
prolonged aerobic steady-state exercise (SSE) intensity due to its association with …

Purpose The health benefits of a training program are largely influenced by the exercise
dose and intensity. We sought to determine whether during a training bout of continuous …

Introduction/purpose The purpose of this study was to test the hypothesis that cardiovascular
(CV) drift and associated decrements in maximal oxygen uptake (V̇O 2max) are greater in …
