When riding outdoors you need to turn your Indoor Trainer function off so that the
Newton’s power measurement sensors will function normally:
1)
Do a Trip Reset
. If your Newton is set to Indoor Trainer mode the message “Trnr
on” will appear.
2)
After the message “trnr on” appears,
press-hold the center button
. “on” flashes.
3)
Use the top/bottom arrows to select “off”
.
4)
Click the center button
. “done” flashes and your Newton is returned to outdoor
mode
NOTE:
YOUR NEWTON WILL NOT PROVIDE ACCURATE WATTS READINGS OUTDOORS IF
“TRNR/ON” IS ENABLED WHEN RIDING OUTDOORS.
FITNESS TEST (FTP TEST)
The Newton’s power-based fitness test (FTP Test) measures your cycling fitness with the
same methods that pro cyclists and coaches use. To do the fitness test you will ride as
hard as you can for 20 minutes. The Newton then computes the average watts you held
during the test, and divides it by your body weight in KG. This “Watts per kilogram” ratio
is a simple and critical measure of cycling fitness. Simply put, the higher your watts per
kilogram the more fit you are and the faster you’ll go, especially on hills.
Also, the average watts held during the Fitness Test, times the multiplier of 0.95, is an
excellent measure of your Functional Threshold Power (FTP). FTP is used by most coaches
as the key measure of your overall aerobic limit and cycling fitness.
The Newton firmware includes a table that interprets your W/KG score as a fitness level
from one to ten. Your fitness level is based on your W/KG measurement and your sex.
Here is the table that is loaded into the Newton firmware:
Fitness'Level'
w/kg''male'
w/kg'female''
1'
042'
041.5'
2'
2.0142.45'
1.5142.08'
3'
2.4642.8'
2.0942.4'
4'
2.8143.46'
2.4142.94'
5'
3.4743.8'
2.9543.23'
6'
3.8144.25'
3.2443.62'
7'
4.2644.82'
3.6244.1'
8'
4.8345.27'
4.1144.48'
9'
5.2845.75'
4.4944.86'
10'
5.75+'
4.87+'
So, for example, if you are male and your 20 minute test returns a W/KG measurement of
2.48, then your fitness level is “3” (the female would score a higher fitness level of “4” for
