This was my first attempt at testing cardiac drift and trying to find my decoupling rate. I took a cardiac output session and divided in to two – consecutive – twenty min sessions. I used a stationary bike that provided average RPM’s and Watts. After a five min warm up I started out at 80 RPM’s – after about 10 min I was unable to maintain this pace and settled for a HR average of 130 as my guide for both sessions.
Average watts: 207/238
Distance: 5.6/5.9 miles
Average RPM’s: 70/72
AVG HR 131
Need to make a few changes for sure, I expected the second session to be more difficult and it wasn’t. I will try again later this week.
