can anyone explain this 2 me I mnot 100% sure about this. VO2=(60mpb x 70mL/beat) (6 mL O2/100 mL blood) = 252 mL O2/min Divided by 70kg, his resting VO2 is about 3.6 mK/kg/min. During maximal exercise this man has a heart rare of 180 bpm, a SV (Stroke Volume) of 115 mL/beat, and an oxygen extraction of 15 mL O2/100 mL blood. SO hi mamimum VO2 is VO2 max = (180 bmp x 115 mL/beat) x (15 ml O2/100 mL/blood) = 3,105 mL O2/min This can be expressed in mL O2/kg/min by dividing bhy mans weight 70kg (154lbs) 3105 mL O2/min divided by 70kg= 44.4mL/kg/min can anyone explain to me how they get there bottom numbers. And wtf is going on here. IM studying to become a PT and this is my 2nd day studying so I hope you guys can help me out with this.
