Maximal Oxygen Uptake Is Underestimated during Incremental Testing in Hypertensive Older Adults: Findings from the HAEL Study

ola Kala shared this article with you from Inoreader Maximal Oxygen Uptake Is Underestimated during Incremental Testing in Hypertensive Older Adults: Findings from the HAEL Study Μέσω Medicine & Science in Sports & Exercise - Published Ahead-of-Print Purpose The present cross-sectional study aimed to investigate whether a maximal oxygen uptake (VO2max) verification phase (VER) could improve the accuracy of a previous graded exercise test (GXT) to assess individual VO2max in hypertensive individuals. Methods Thirty-three older adults with hypertension (24 women) taking part in the Hypertension Approaches in the Elderly Study (NCT03264443) were recruited. Briefly, after performing a treadmill GXT to exhaustion, participants rested for 10 min and underwent a multistage VER to confirm GXT results. Individual VO2max, respiratory exchange ratio (RER), maximal heart rate (HRmax), and rating of perceived exertion (RPE) were measured during both GXT and VER tests. Mean values were compared between bouts using paired sample t-tests and VO2max was also compared between GXT and VER on an individual basis. Results Testing was well tolerated by all participants. Both absolute (p=0.011) and relative (p=0.014) VO2max values were higher in VER than in GXT. RER (p View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
