Prior to the start of the IHRSA congress in Brasil, h/p/cosmos took the time to perform an analysis. We compared the consequences of uphill and downhill walking on the cardiovascular system, utilizing the pulsar 3p treadmill and VO2max metabolic cart. Our test subject was Ms. Betina Dantas, professional ballet dancer and instructor. She also insisted on performing a few figures on the treadmill. Of course only whilst secured with the safety arch.
