MAF Test

It was hard for me to adjust to the Maffetone Training by following 180 Formula during the 1st week of my training. I had mentioned in my previous posts that I “cheated” on strictly following the 180 Formula where my Maximum Aerobic Function’s (MAF) Heart Rate shoud be 121 beats per minute. I started with 142-145 beats per minute for the first 2-3 days until I was able to adjust to 138 beats per minute. After a few days, I was comfortably running, slow jogging and walking at 132 beats per minute.

After another 2-3 days, I was able to bring down my maximum aerobic heart rate to 121 beats per minute. After 3 weeks of running and walking within my MAF of 121 beats per minute based from my 180 Formula, I did my first MAF Test. As suggested by Dr. Phil Maffetone, a runner must first warm-up by gradually increasing the heart rate from a resting rate to a range of maximum aerobic rate, from the lowest range of 111 beats per minute to my maximum rate of 121 beats per minute. Warm-up is being done by slow walking up to brisk walking for almost 15-16 minutes which is equivalent to 4 laps at the oval track. It is notable in my running workouts that I don’t perform any stretching exercises before and after my runs. However, a 10-minute squat after my running workout had been a “must” and later became a habit.

Once my max aerobic rate range of 111-121 bpm is reached, I start jogging/running and complete 4 laps on the oval track  which is equivalent to one mile. The time is recorded and written on a paper. After a short recovery by walking of at least 30 seconds, I do my second set of one mile run until I complete five repetitions of one mile run. The time of each mile repetition is being recorded. After the 5th mile, I have to cool-down by walking another 4 laps until my heart beat rate would gradually go down to the rate that was registered before I started my workout. After 3-4 weeks, another MAF Test has to be done.

So far, I just completed my 3rd MAF Test last week. The results are shown in a tabulation below:

16:50 16:27 16:10
17:32 17:18 16:56
18:10 17:41 17:27
18:55 18:39 17:35
19:28 19:08 17:52

The tabulation would show that I am gaining my “aerobic speed” which means that I am getting faster with a constant HR of 121 beats per minute. When I started to strictly follow the 180 Formula, the distance (as registered by GF 305) I could cover for a hour was 5.6 kilometers. After one week of max HR of 121 bpm, I could cover 5.66 kilometers per hour. After 3 months of 180 Formula/MAF training, my distance covered for one hour is 5.88 kilometers per hour!

Sometimes I vary my method of determining my improvement. I would run/jog for a distance of 8 kilometers (5 miles) continouosly at the oval track by maintaining an average HR of 119-121 beats per minute and try to record the time elapsed to cover the distance. On my first try, I registered a time of 1:31:20 hours. After a few days, I registered a time of 1:30:04 hours. At present, I was able to register my fastest time in 1:25:48 hours for the said distance.

My typical weekly workout would consist of “doubles” during the day—1.5 hours in the morning and another 1.5 hours in the late afternoon. Such workout would include 15 minutes of warm-up, 15 minutes of cool-down, and running for one hour at an average HR of 121 bpm. On the next day, I do 2.5 hours with 2 hours of actual running and the rest for my warm-up and cool down. I do this kind of workout in the morning only which is also considered as my “heat training” under the sun as I start my workout at 8:00 or 9:00 AM. On the next day, I go back to my daily “doubles”. And the cycle continues throughout the week. My long runs during weekends would last up to 3 hours of running & walking, making sure that my average HR would not be more than 121 bpm. The last MILO Elimination Run was my longest LSD for almost 6 hours, covering a distance of 32 kilometers.

It is very evident that I measure my running workouts by the TIME that my feet are on the ground! The distance covered during these timed workouts is just a data that provides a good feedback and evaluation of my improvement in this kind of training. At least, the minimum of hours per week in my training is 12 hours.

It is worthy to note that within this 3-month of strictly following the max aerobic HR of 121 bpm, I was able to try and complete my “Two-Week Test” to determine my carbohydrate intolerance, a situation when the body has more carbohydrates stored in the body system. This “Test” greatly improved my resting HR, lowering and sustaining my MAF’s max aerobic HR to 121 bpm during my workouts, reduced my weight to 135 pounds, and no longer have sleepy feeling after lunch or after a heavy meal. The best result is that I can control my urge to eat foods rich in carbohydrates.

I hope there would be good results in my endurance capabilities as soon I start my anaerobic/speed training in the weeks to come.
