OPERATION Workout Programs (Continued)
For example: If the heart rate during stage 1 is 92 bpm, the workload for
stage 2 will be 75w. (Please refer to the chart above)
Stage 2, Stage 3, Stage 4:
Actual heart rate will be measured during the second and third minute of each
stage. When the stage ends, the difference of these heart rates will be calculated.
(Third minute heart rate minus second minute heart rate)
a. If the difference is less than or equal to 5bpm, and heart rate is greater than or
equal to [(220-age)×0.85]-10, the fit test ends.
b. If the difference is less than or equal to 5bpm, and heart rate is less than [(220-
age)×0.85]-10, the user enters the next stage.
c. If the difference is greater than 5bpm, the stage will be extended for one minute
until the heart rate stabilized.
The difference in heart rate between the extended minute and the previous minute
is subject to conditions a, b, and c to determine how the test proceeds.
Additional Stages: Results are determined according to a, b and c conditions of
Stage 2, 3 and 4.
(3) When entering a new stage, Level will be adjusted according to the actual RPM
to meet the expected workload (Watt).
Example: The workload at Stage 2 is 100W, actual RPM is 51; Level will be
automatically adjusted to 7 to generate a workload more than 100W
4. Calculation
The oxygen cost (VO2 max) of the user will be calculated using the following
equation. The calculated values will indicate the user’s score according to the chart
below.
SM1 = (Stage 2 Watt/kg × 10.8) + 3.5 + 3.5
SM2 = (Last Stage Watt/kg × 10.8) + 3.5 + 3.5
HR1 = (Stage 2 second to last minute HR + Stage 2 last minute HR) / 2
HR2 = (Last Stage second to last minute HR + Last Stage last minute HR) /2
b = (SM2 ─ SM1) / (HR2 ─ HR1) Note: b= slope
HRmax = (220 ─ age)
VO2MAX = sm2 + (b × (HRmax ─ HR2))
*HR1 = (Sum of last two minutes’ HR for stage 2) / 2
= (Average of stage 2’s last two minutes’ HR measures)
HR2 = (Sum of last two minutes’ HR for last stage) / 2
= (Average of last stage’s last two minutes’ HR measures)
