Heart Rate Training Seems to Work!

Standard

For the past 8 days now I have been focused on heart rate training, and surprisingly I am seeing positive results already. I expected to see improvement but assumed that it would take some time before I saw the type of results that I’ve seen. I also want to point out the fact that I use words like slow and slower in this post. In no way am I attempting to compare myself to anyone else or label anyone as a slow runner. A 12:00 mile pace may be a goal for some runners and that’s fine because we all work from where we are. Having run a 22:04 5k, backing down to some of the speeds necessary to stay within my target heart range has been quite an adjustment for me. Your mileage may vary 😉 I also want to note that I have been fasting for each of the runs that are discussed here as I’m teaching my body to burn fat more efficiently (also in the Maffetone plan).

What is heart rate training? Basically it’s a system that was put together by Phil Maffetone that helps determine your optimal training heart rate zone; a zone that keeps you in your body’s aerobic system rather than the anaerobic system which stresses your body more. After reading all of the details I was able to determine that my training heart rate should be between 135-140 beats per minute (the formula allows for 130-140, but I have elected to shorten that window). In order to benefit from the heart rate training I will need to keep my heart rate in the 135-140 zone during all runs as well as all cross-training activities. Using running as an example, this means that once I get my heart rate up to 135 I need to stay between 135 and 140 until the workout is finished. The bad news is that this pretty much eliminates the possibility of run/walking for those that typically run using the Galloway Method because walking would lower the heart rate below the bottom end of the range. This also eliminates strides, intervals, repeats, tempo runs, fartleks, ladders, progression runs and any other attempts at working on speed. It’s temporary.

Last Tuesday I set out for my first crack at this different type of training before the sun came up. As it sometimes does, my heart rate jumped way up right off the bat (164 max), but after about three minutes I was back in my target range, finishing the first mile in 10:27 with an average  of 141 bpm. Yeah, this type of training takes a little getting used to, especially if you’re used to running by pace more than feel. As expected the remaining miles were each slower than the previous mile: 11:12, 11:45, and 12:00. The final half mile was on pace to be even slower than 12:00. Overall I averaged 11:27 per mile and a 138 heart rate.

Without knowing exactly what to expect I just accepted these numbers as my starting point and decided to run the same distance each of the next two days to make comparing data from day to day a little easier (#NumbersNerd). On Wednesday my first mile was about the same (10:29/131bpm) but the other miles showed more and more improvement: 10:31, 10:47, 11:07, and the final half at 11:19 pace. The day’s averages were 10:48 and 135bpm. Interesting…. About 40 seconds faster per mile with a lower heart rate. Thursday was a split compared to Wednesday, with some numbers better than Wednesday and some worse. I’ll post the specifics below if you’re interested.

Saturday’s run was different on many levels (non-fasting, run later in the day under hot sun, higher stress, etc.) and the results reflected the differences. I’m going to skip the specifics until I can determine which elements affected me and which ones didn’t, but the entire run was done trying to stay in the 135-140 range.

Sunday was a longer run, so I checked the numbers for 5 miles (to compare to previous runs) and for the full 8.2 miles. More improvements! At five miles I was averaging a 10:44 pace and 135 bpm, and for the full run, an 11:09 pace and 136. Yeah, I averaged a faster pace for 8.2 miles than I did 5 days ago for 4.5 miles and at a lower heart rate. Hmmmm, I’m seeing a trend that I like. My sixth run, a week after my first run: 10:20 average pace for 5 miles at 134 bpm. Last Tuesday was 11:27/138 bpm! That’s 67 seconds per mile faster at a lower heart rate. Today’s first mile was at 9:44 and a 127 heart rate! I’m actually having trouble getting my average heart rate for the first mile high enough without going over the 140 mark because it is increasing so slowly.

I have plans to continue this training for about six weeks and if the improvements keep coming the way that they have so far….. I am getting excited to think of the possibilities! If you have any questions about this training method that I might be able to answer please feel free to contact me. There are more details about the Garmin that I use here.
