My first full week of running! Feeling a little bit stronger every day. With every workout I thought about being one step closer to running 50 miles. It won’t happen tomorrow or next week. It won’t even happen this year. But, it will happen!
What my week looked like:
Monday: Les Mills Pump, PT
Tuesday: 45 mins. 1:1 run/walk .25 intervals, PT
Wednesday: Les Mills Pump, PT
Thursday: 45 mins. 1:1 run/walk .25 intervals, PT
Friday: Les Mills Pump, PT
Saturday: 45 mins. 1:1 run/walk .25 intervals, PT
Sunday: Yoga, PT
Next week? 1:2 intervals. Sweet!
Last week I mentioned trying an oximeter. As a runner with Exercise Induced Asthma I was curious when given the opportunity to review the Health-Ox Fingertip Pulse Oximeter. The Health-Ox is a small, convenient pulse oximeter that gives you instant and accurate pulse and oxygen saturation levels. It comes with a lanyard and a protective rubber cover to make it easier to use during exercise.
Why are blood oxygen levels important? If you have high blood oxygen levels, your body will transport oxygen throughout your body more quickly. If you have low blood oxygen levels, your body will send oxygen to your muscles at a much slower rate which can cause you to feel fatigued and make it difficult to get the most out of your workout.
I used .25 mile run:walk intervals. With 3 runs I tried the oximeter after the first .25 mile walk and then again after the first .25 mile run.
It was interesting to notice that during my last run of the week on Saturday my oxygen levels were relatively lower than earlier in the week. That was also the morning I woke up feeling like I was catching a cold. It doesn’t seem like that was a coincidence. Good to know.
As a runner, when might I want to monitor my oxygen levels? During runs with conditions that I know affect my asthma, extreme temperatures, humidity and cold symptoms. Healthy individuals generally have a oxygen saturation level of 97-99%, though any level above 92% is generally considered safe and normal.
Have you ever trained with run/walk intervals?
