MAF 180 Heart Rate Training

The 180 Formula

Here is a great article that many TI practitioners will appreciate.  I am a hugh fan of the way of training!

because you can be in a very mindful and intentional mental state because the lack of stress on the body will allow you to truly “practice” running, cycling and swimming and continue your Kazien or continual improvement.

The 180 Heart Rate Formula was developed by Dr. Philip Maffetone who went on to coach triathlon greats Mark Allen and Mike Pigg.  Even though this formula is over 20 years old and not considered very “sexy” (it’s the only heart rate formula that I know that doesn’t require a calculator) since there is no LTHR tests, VO2 Max tests, or complications.  It is very straight forward.

The 180 Formula

To find the maximum aerobic heart rate:

1.Subtract your age from 180 (180 – age).

2. Modify this number by selecting a category below that best matches your health profile:

1. If you have, or are recovering from, a major illness (heart disease, high blood pressure, any operation or hospital stay, etc.) or you are taking medication, subtract an additional 10.

2. If you have not exercised before or have been training inconsistently or injured, have not recently progressed in training or competition, or if you get more than two colds or bouts of flu per year, or have allergies, subtract an additional 5

3. If you’ve been exercising regularly (at least four times weekly) for up to two years without any of the problems listed in a or b, keep the number (180 – age) the same.

4. If you have been competing for more than two years duration without any of the problems listed above, and have improved in competition without injury, add 5.

For example, if you are 30 years old and fit into category b: 180 – 30 = 150, then 150 – 5 = 145.

During training, create a range of 10 beats below the maximum aerobic heart rate; in the example above, train between 135 and 145 staying as close to 145 as possible. To develop the aerobic system most effectively, all training should be at or below this level during base building. As the aerobic system develops, you will be able to run faster at the same maximum aerobic heart rate.

Once a great aerobic base is developed, an athlete can develop anaerobic function, if desired. In some cases this may not be necessary or the time and energy is not available for such endeavors.

One other significant benefit of applying the 180 Formula is the biochemical response: production of free radicals is minimal at this training level compared to training at higher heart rates. Free radicals contribute to degenerative problems, inflammation, heart disease, cancer and rapid aging.

As important as finding the correct aerobic training heart rate is the process of self-assessment.

Self-Assessment: The MAF Test A significant benefit of aerobic base building is the ability to run faster at the same effort, that is, at the same heart rate. A heart monitor can help objectively measure these improvements using a test I developed in the mid 1980s called the maximum aerobic function (MAF) test.

Perform the MAF Test on a track, running at the maximum aerobic heart rate. A one- to five-mile test, with each one-mile interval recorded, provides good data. The test should be done following an easy 12–15 minute warm up, and be performed about every month throughout the year. Below is a 5-mile MAF

Test of a runner training at a heart rate of 150:

Distance Time (min:sec)

Mile 1 - 8:21

Mile 2 -  8:27

Mile 3 - 8:38

Mile 4 - 8:44

Mile 5 -  8:49

During an MAF Test, it is normal for the running times to slow each mile – the first mile should be the fastest and the last the slowest. If this is not the case, it may indicate the lack of an effective warm up. In addition, the test should show faster times as the weeks and months pass. For example, over a four month period, we can see the endurance progress in the same runner from the above MAF Test. Note the aerobic speed improvement between April and July:

----------April--  May---June--- July

Mile 1 8:21   8:11  7:57   7:44

Mile 2 8:27  8:18  8:05   7:52

Mile 3 8:38  8:26  8:10   7:59

Mile 4 8:44  8:33  8:17    8:09

Mile 5 8:49  8:39  8:24    8:15

This improvement is typical during the aerobic base period. Some improve at a faster rate, others slower. Most importantly, if you’re not improving within a three- or six-month period, it means something is wrong. It may be a dietary or nutritional factor, excess stress, overtraining (such as too many miles), etc. In some cases, it may be the maximum aerobic heart rate is too high (often from choosing the wrong category in the 180 Formula). Moreover, a reversal of aerobic function, i.e., slowing of aerobic pace during base training, may indicate an impending injury – enough of a reason to perform the MAF Test regularly.

Progress should continue in some form for three to six months or more before aerobic benefits may reach a normal plateau. Adding anaerobic work to the schedule before this plateau may impair (and ultimately even reverse) further aerobic progress.

The greatest benefit of the MAF Test is that it objectively demonstrates aerobic improvement in the form of aerobic speed. These changes also reflect competitive improvement.

Competition

A direct relationship exists between the maximum aerobic pace (as measured by the MAF Test) and competition. Essentially, increasing aerobic function improves competition (recall that events lasting more than two minute’s duration obtain most energy from the aerobic system).

Data gathered on hundreds of runners I trained over a period of several years showed that the MAF Test was positively correlated with race pace – as the MAF Test improved, so did competition. The chart below, based on actual MAF Tests and 5 kilometer running race times, demonstrates this relationship.

MAF     5K Race Min/Mile     Race Pace Time

10:00          7:30                           23:18

9:00             7:00                          21:45

8:30             6:45                          20:58

8:00            6:30                          20:12

7:30            6:00                          18:38

7:00            5:30                          17:05

6:30            5:15                           16:19

6:00           5:00                           15:32

5:45            4:45                           14:45

5:30            4:30                          13:59

The above runners included those who developed an aerobic base, and raced on a flat, certified road course, or track. Most did not perform any anaerobic training, and for most, this was their first competition of the spring or fall racing season. Moreover, 76% of these athletes ran a personal best time for this distance! Similar relationships exist for longer events and for other sports.

The use of a heart rate monitor takes the guess work out of training and can help increase aerobic speed. It can also help prevent injury, ill health and burn more body fat
