Comparison of stationary ZAN 600 toportable Cosmed K4b2 metabolic cart in experienced game sport athletes
Journal Title: International Journal of Sport, Exercise and Health Research - Year 2017, Vol 1, Issue 1
Abstract
Background: In sport games, different stationary and portable respiratory gas exchange measurement (RGEM) analysis systems are often used in parallel for accuracy and comparison purposes. Aims and Objectives: The aim of this study was to determine the agreement and consistency of the portable Cosmed K4b2 and stationary ZAN 600RGEM systems in an incremental treadmill running test. Study Design and Setting: Eleven sport students with a strong background in different sport games performed two incremental treadmill running tests within one week. Materials and Methods: Oxygen uptake (VO2) was determined by using the portable Cosmed K4b2 in breath-by-breath mode and compared to data of a stationary ZAN 600 RGEM system. Statistics: Agreement and consistency between the two systems were calculated using the interclass correlation coefficient (ICC) and the difference in maximal oxygen uptake (VO2max) via paired sample t-tests. Results: The results revealed a strong agreement at the submaximal and maximal running speed (ICC=0.90-0.95) and the VO2max (ICC=0.97); however, there were also significant differences between the measuring systems during certain treadmill speeds. Conclusion: Our results indicated that the Cosmed K4b2 and the ZAN 600 are valid and reliable RGEM systems to determine VO2 uptake in specific field and in general laboratory tests within the same testing group.
