I have been trying to get ready for a the Avenue of the Oaks Century on May 1 and my training has been inconsistent at best….insert excuses here. Today I was able to spend 2 hours on a ride and I wanted to push a bit harder that normal.
SInce I no longer go to cardiac rehab. I try to mirror what the “maintenance” program I was on did when it comes to protocol. Each time I went to rehab the workout started with the following:
- Weigh myself.
- Relax and sit in a chair (of my own choice I closed my eyes and relaxed my whole body durigng the next steps).
- They would hook up the blood pressure cuff, and oxygen monitor.
- Then take the reading for my BP, resting HR & Oxygen level.
I do my best to do all of the above things before I do any type of workout or riding (I’m in the market for a new blood pressure monitor as the electric one I had been using was not accurate when I brought with me to an appointment with my doctor and compared it with hers). Now during the cardiac rehab sessions they would check my oxygen levels 2-3 times, more if I was trying something new or pushing up a level of intensity. At home I only check it before I workout and occasionally after my cool down and when I push myself (now getting to the point of this entry) like I did today. Since I was heading out to ride twice as long as had I the past weeks I decided to take my Nonin Onyx Fingertip Oximeter with me to check throughout my ride. I want to point out at this point that this is same monitor 1 of my doctors uses, and 2 of my rehabs use so that is how I qualified it’s purchase. (one other point it is a nice way to check the accuracy of my heart rate monitor as well).
Today I used at the first sign of feeling like the ride should have been a bit easier and I didn’t believe my HRM, it was correct the oximeter read 138bpm and 98%O2. The next time was after a moderate climb and I hit 164 bpm (my doc say to stay under 160) Oximeter read 161bpm ( it took a few seconds to stop and put it on my finger) and 96% O2. It is also a good thing to have when I’m sucking wind and I can be sure it’s just from being out of shape vs a true loss of O2. I used it one more time when I started to feel tired and then after my cool down. I probably won’t bring it with me on a ride again until I do the century on May 1.
It is a useful tool to have if you work out on your own. It provides me with 2 things, 1: Ability to let me doctor know more information about my health & 2. Oxygen content of your blood is only a small factor when determining your risk for a cardiac event but it does provide me with a bit of assurance that my heart is doing O.K.
