Submax Cycle Ergometer Test

1. Choose bike protocol
2. Individualized protocol (Branching) e.g. YMCA
3. Standardized protocol e.g. 300, 600, 900, 1200, etc
4. Run test to obtain HR, BP, & RPE at each work rate e.g. 90 bpm @ 150 kgm/min
5. Make data table which includes workloads and all variables collected

Bike date data and protocol:

My age is 27

My bike results are :

Stage 1 :

-Workload : 0,5

-HR: 89bpm

-RPE: 4

Stage 2 :

-Workload : 1,5

-HR: 109bpm

-RPE: 11

Stage 3 :

-Workload : 2,0

-HR: 120bpm

-RPE: 12

Stage 4 :

-Workload : 2,5

-HR: 142bpm

-RPE: 14

1. Graph submax HR(heart reate) vs. Work rate data
2. Plot data on graph paper (or on computer); draw line of "best fit" (HR>130)
3. Extrapolate line up to age-predicted HRmax

[ 208 - (0.7 * age)]

(More accurate than 220-age )

1. Calculate the % predicted HRmax attained during highest stage
2. E.g. 143 bpm / 190 bpm = 75% pred. HRmax
3. Drop perpendicular to Work rate axis
4. This estimates maximal work rate

1. Determine energy cost of max Work rate (VO2 max)
2. Only use this first equation if rev/min are vastly different from 50

Kgm/min = __ kp x __m/rev x __rev/min

6 meters/rev (assume 50 rev/min)

for this bike

1. VO2 = (1.8 x__kgm/min / body wt kg)+ 7

e.g. 300, 450, 600, etc.

1. Convert cycling VO₂ to walk/run VO₂ (weight-bearing):
2. Cycling VO₂ values are ~90% of treadmill VO₂ (TM) values
3. E.g.If cycling VO₂=35 mL/kg/min, then: 90% of TM = 35

So: DIVIDE BY 0.9: 35 / .90 = 38.89 mL/kg/min for walk/run
