HR Based on Peak to Peak Measurements
60s/time btwn peaks
Cardiac Output Equation
CO =Heart Rate x Stroke Volume
HR from R-R Interval (Blood Volume Pulse)
HR = 1/Cycle Length (R-R Interval) x60 s
RER
VCO2/VO2
RER greater than 1
Anaerobic
CO2 greater than O2
RER is less than 1
Aerobic
CO2 is less than O2
Respiratory Quotient
CO2/O2 in Cells/Minute
Breathing Frequency in Normal Ventilation is how many BPM?
15 Resp Cycles/Min
VE
Frequency x Tidal Volume
Theoretical HR Max
220-Age
Rate O2 Consumption
VO2= Vi(FIO2-FEO2)
Rate CO2 Produced
VCO2= VI x FECO2
Prediction Equation for VO2 Max
VO2 = 500 + (WR x10mL/watt)
VO2 Units
mL/kg/min
Performance Equation
WR(w)/Body Weight (kg)
VO2 Max Prediction ACSM Running
VO2 Max = (0.2xSpeed) + (0.9 x speed x fxnal grade %) +3.5
VO2 Max Prediction ASCSM Walking
VO2 Max = (0.1xspeed) + (1.8 x speed x fxnal grade %) +3.5
VO2 Max Prediction FRIEND
VO2 Max = Speed x (0.17 x fxn grade % x 0.79) +3.5

Fat Oxidation Equation (g/min)
Fat Ox = 1.695 x VO2 - 1.701 x VCO2
Carb Oxidation Equation (g/min)
Carb Ox = 4.585 x VCO2 -3.226 x VO2
What is Fat Max
Stage at which Fat Oxidation is at its highest
