Ramp Test with Respiratory Focus

Today I did a 4 minute ramp from 125 to 250 watts.

The focus was on trying to have as high of a Tidal Volume (O2 in L/min divided by RR .. respiration rate) as possible.

I kept my cadence steady the entire time.

Test data ...

Wattage -- Tidal Volume -- % of FVC

125 -- 2.7 -- 46%

150 -- 3.1 -- 52%

175 -- 4.2 -- 70%

200 -- 4.6 -- 76%

225 -- 3.8 -- 63%

250 -- 4.2 -- 71%

Right after the ramp I completed 10 minutes on 3.0 L at 25 rr on Spiro normally a level that isn't too challenging ... However it was much more work than normal after the on the bike session.

Was pretty happy with this first session. Goal is to improve to 80 plus % on the bike at and above Balance Point.

Next session will be fixed Balance Point heart rate while attempting same breathing session...data will follow.
