If Carla (63 kg) wants to burn 250 kcals by cycling 80 rpm’s against 1.5 kp of resistance, how long will she need to cycle? According to MET values would this be a Light, Moderate, or Hard activity? CYCLE EXAMPLESCycle ergometry problems always assume using a standardMonark cycle with 6m/rev flywheel and MUST specify theweight of the subject300 kpm/min; 70 kg subjectVO2 = 3.5 ml/kg/min*70kg +0+ 2.0ml/kpm * 300 kpm/min= 245 ml/min + 600 ml/min=845 ml/min (absolute terms) or 845/70kg = 12.07ml/kg/min (relative terms)100 Watts; 50 kg subject*VO2 = 3.5 ml/kg/min*50kg + 0 + (2.0ml/kpm * 100 Watts 6kpm/min/Watt)== 175 ml/min + 1200 ml/min=1375 ml/min (absolute terms) or 1375/50kg = 27.5ml/kg/min (relative terms)OTHER CALUCLATIONSMET Values:Classifications1 MET = 3.5 ml/kg/minLIGHT ActivityMODERATE ActivityMET<3.0 MET3.0-6.0 METActivity> 6.0 MET HARDUsing Walking example (3.0 mph, 5% grade)VO2 = 18.7 ml/kg/minMETS = 18.7/3.5 = 5.34 METs, thus MODERATE

The “mean-speed theorem” for finding average velocity under constant acceleration, proposed by the Oxford Calculators, and demonstrated geometrically by Nicole Oresme, is expressed algebraically as: density = weight/volume (m1)(v1) = (m2)(v2) (vm) = 1/2 (v0 + vf) s = (v0)(t) + 1/2 (a)(t2) velocity = distance/time
