Collecting objective physical activity data from research participants are increasingly done
using consumer-based activity trackers. Several validation studies of Polar devices are …

We sought to determine the incidence of 'true'VO 2 max confirmation with the verification
procedure across different protocols. 12 active participants (men n= 6, women n= 6) …

Background No consensus exists on how to average data to optimize O2max assessment.
Although the O2max value is reduced with larger averaging blocks, no mathematical …

To evaluate if the Hexoskin smart shirt (HxS) would produce valid and reliable
measurements for heart rate (HR), respiratory rate (RR), minute ventilation (VE), step count …

Background The aim of this study was to assess the accuracy of three different sport watches
in estimating energy expenditure during aerobic and anaerobic running. Methods Twenty …

Purpose: The purpose of this study was to evaluate the effect of pre-exercise alkalosis,
induced via ingestion of sodium bicarbonate, on changes to lactate/pH regulatory proteins …

Purpose The portable metabolic analyzer COSMED K5 (Rome, Italy) allows for switching
between breath-by-breath (BBB) and dynamic micro-mixing chamber (DMC) modes. This …

“Metabolic Equivalent”(MET) represents a standard amount of oxygen consumed by the
body under resting conditions, and is defined as 3.5 mL O2/kg× min or~ 1 kcal/kg× h. It is …

Purpose: Automated metabolic analyzers are frequently utilized to measure maximal oxygen
consumption (V˙ O 2 max). However, in portable devices, the results may be influenced by …

Physical fatigue is debilitating and common among kidney transplant recipients (KTR s).
This study investigated the mechanistic aetiology of physical fatigue in this setting through …
