Jämförelse mellan MOXUS modular metabolic system och AMIS 2001 (Swedish)
Introduction: There are various different methods to measure VO2 max in people. The Douglas Bag method is still seen as a criterion method, however, in recent years there has been a rise in the use of automatic gas analyzers that provide information in real time. It is only a few studies that have looked at gas analyzers during high intensity.
Purpose: The purpose of the present study was to compare the MOXUS modular metabolic system with the AMIS 2001. Nine participants, age 29 ± 10 years, completed three VO2 max tests via The Bruce Treadmill Protocol. Two tests were measured via the MOXUS system and one via the AMIS. These were conducted in a random order. The VO2, VC02, VE and RQ were compared between tests.
Results: At low intensities there was no significant difference between gas analyzers, however at maximum intensity the AMIS recorded higher VO2 (p<0, 01), VCO2 (p<0,001), VE (p<0, 05) and RQ (p<0,001). Between the two tests measured with the MOXUS system, there were no significant differences at maximum intensity.
Discussion: The higher values measured via the AMIS system can perhaps be explained by differences in sensitivity to high ventilations. If there is a difference in ventilation there will obviously be a difference in VO2 and VCO2. The fact that RQ was also significantly higher at maximum intensity shows that the AMIS measures a greater difference between VO2 and VCO2 than the MOXUS system. The CV value for MOXUS between the two tests was very high in comparison to other studies, this can be because there was a relatively large difference in how well trained the participants were.
