An Algorithm for Predicting Longevity
For the test, participants exercised on a treadmill at increasing speed and incline. While they were exercising, the researches measured peak heart rate (%MPHR) and their ability to withstand physical exertion. On that latter point, they measured metabolic equivalents, or METs, which gauges how much energy the body expends during exercise. The more intense the exercise, the higher the METs (e.g. slow walking = ~2 METs, whereas running = ~8 METs).

You can get your MPHR for your age here. I found a chart of METS here for various exercises.
| Activity | METS | Activity | METS |
| Aerobic Dancing | 6.0 | Running 12 min/mile | 8.5 |
| Backpacking | 7.0 | Racquetball | 8.0 |
| Badminton | 7.0 | Rugby | 8.3 |
| Basketball | 6.0 | Skating ice/roller | 7.0 |
| Bicycling - 24mph | 5.0 | Skiing cross country | 8.0 |
| Calisthenics | 4.5 | Soccer | 8.0 |
| Golf | 5.0 | Softball | 5.0 |
| Gymnastics | 5.5 | Swimming | 6.0 |
| Handball | 8.0 | Tennis | 7.0 |
| Hockey | 8.0 | Volleyball | 4.0 |
| Horse riding | 3.5 | Walking | 3.5 |
| Running 8 min/mile | 12.5 | Weight lifting | 4.5 |
| Stage | Minutes | % grade | km/h | MPH | METS |
|---|---|---|---|---|---|
| 1 | 3 | 10 | 2.7 | 1.7 | 5 |
| 2 | 3 | 12 | 4.0 | 2.5 | 7 |
| 3 | 3 | 14 | 5.4 | 3.4 | 10 |
| 4 | 3 | 16 | 6.7 | 4.2 | 13 |
| 5 | 3 | 18 | 8.0 | 5.0 | 15 |
| 6 | 3 | 20 | 8.8 | 5.5 | 18 |
| 7 | 3 | 22 | 9.6 | 6.0 | 20 |
Total Durations = 21 minutes
So, if I'm understanding this correctly. If I reach a 160 heart rate out of 179.0 MPHR predicted for my 41 years of age while running 12 minute miles worth 8.5 METS. My score would be:
83.7 12(8.5) - 4(41) = 21.7
The same heart rate for my age running 8 minute miles:
83.7 12(8.5) - 4(41) = 69.7
