The Cosmed K4 Telemetry System as an Accurate Device for Oxygen Uptake Measurements during Exercise

Oxygen Uptake Kinetics during Exercise

This thesis has investigated oxygen uptake ( i r02) kinetic regulation during whole body exercise by investigating not only the breath-by-breath V O ~ response to a change in work rate but also incorporating an examination of data analysis processes and simulation of a physiological V O ~ model. Five experiments have been completed to answer the following questions: Experiment 1: What effects d...

Oxygen uptake kinetics during exercise.

The characteristics of oxygen uptake (VO2) kinetics differ with exercise intensity. When exercise is performed at a given work rate which is below lactate threshold (LT), VO2 increases exponentially to a steady-state level. Neither the slope of the increase in VO2 with respect to work rate nor the time constant of VO2 responses has been found to be a function of work rate within this domain, in...

Title : Oxygen uptake during repeated - sprint exercise

Excessive oxygen uptake during exercise and recovery in heavy exercise.

The aim of this study was to determine whether excessive oxygen uptake (Vo2) occurs not only during exercise but also during recovery after heavy exercise. After previous exercise at zero watts for 4 min, the main exercise was performed for 10 min. Then recovery exercise at zero watts was performed for 10 min. The main exercises were moderate and heavy exercises at exercise intensities of 40 % ...

An Effective, Versatile, and Inexpensive Device for Oxygen Uptake Measurement

In the last ten years, the use of fluorescent probes developed to measure oxygen has resulted in several marketed devices, some unreasonably expensive and with little flexibility. We have explored the use of the effective, versatile, and inexpensive Redflash technology to determine oxygen uptake by a number of different biological samples using various layouts. This technology relies on the use...
