Comparison of the YMCA and a Custom Submaximal Exercise Test for Determining VO2max
MAXIMAL OXYGEN UPTAKE V˙O2 SLOW COMPONENT CYCLE ERGOMETER TESTING
2017/4/13
The maximal oxygen uptake (V˙O2max) is deemed the highest predictor for all-cause mortality, and therefore, an ability to assess V˙O2max is important. The YMCA submaximal test is one of the most widel...
