A flattening of the oxygen uptake–work rate relationship at severe exercise indicates the
achievement of maximum oxygen uptake VO 2 max. Unfortunately, a distinct plateau VO 2 pl …

Study design Cross-sectional cohort study. Objectives To compare ratings of perceived
exertion (RPE) on Borg's 6–20 RPE scale and Category Ratio 10 (CR10) in able-bodied …

This study aimed to examine sex differences in oxygen saturation in respiratory (SmO2-m.
intercostales) and locomotor muscles (SmO2-m. vastus lateralis) while performing physical …

The 3,000 m run is a frequently used field test for evaluating aerobic fitness. The test has
previously been validated using smaller sample sizes and with focus restricted to the …

Objective This study compared the robustness of a V˙ O 2-plateau definition and a
verification-phase protocol to day-to-day and diurnal variations in determining the true V˙ O …

In this study, we aimed to determine the exercise intensities eliciting the highest (FATmax)
and the lowest (FATmin) fat oxidation rate in male cyclists and to compare these intensities …

Cardiorespiratory fitness (CRF) is intricately related to health status. The optimal approach
for CRF quantification is through assessment of peak oxygen uptake (VO 2), but such …

Maximal oxygen uptake (VO2max) declines with advancing age and is a predictor of
morbidity and mortality risk. The purpose here was to assess the utility of constant load tests …

The purpose of this study was to analyze the influence of grade of obesity on the probability
of achieving a VO2 plateau and threshold secondary criteria for verifying VO2max during a …

Purpose To compare performance data of adolescents collected with five different bicycle
spiroergometry protocols and to assess the necessity for establishing standard values for …
