Blood pressure medication and heart rate issue
I planning to call my dr and discuss this issue with him, to get a real definitive answer, but thought maybe someone might be familiar with this issue.
I'm 53 y/o, I weighed 220 most of last year. I've been on high blood pressure med (atenolol) for a long time, maybe 15 years. I've had a bike for years, but really gotten into riding the past 2 years. Logged 2,248 miles in 2009, including doing Ragbrai.
I've never been a fast rider (usually at the back of the pack) and have trouble getting up hills. I've suspected it might partly be due to the atenolol, as it slows my maximum heart rate. It's really hard to sustain a heart rate of much above 120. I discussed this with my dr, he said told me it could be causing my problem getting up hills, but that it should give me better stamina.
The last 3 months, I've changed my diet, and as of today, have lost 22 pounds. Also, i've been checking my bp daily, and it's dropped, averaging 120/80. I began tapering off the atenolol, so I've not taken it for the last month.
This time of year, I exercise on my Schwinn Airdyne. On days when I took the atenolol, I could hardly get my heart rate above 115. Since I've been off the med, my heart rate on the Airdyne is about as follows:
After 10 minutes, mid 130's
15-20 minutes, mid 140's
25+ minutes, upper 140's to low 150's
These heart rates are with what I'd call with a moderate effort.
I'm really trying to loose weight. According to a chart, to burn fat I need to be in a heart rate zone of 129-139. Aerobic level would be 139-149.
Am I correct, that being on the atenolol could be hindering weight loss?
