Diaphragm Exercises Reduce Blood Pressure
"The muscles we use to breathe atrophy, just like the rest of our muscles tend to do as we get older," explains researcher Daniel Craighead, an integrative physiologist at the University of Colorado Boulder. To test what happens when these muscles are given a good workout, he and his colleagues recruited healthy volunteers ages 18 to 82 to try a daily five-minute technique using a resistance-breathing training device called PowerBreathe. The hand-held machine — one of several on the market ... 1

Esports Workout Regimen
Eating right, sleeping right, exercising, cleaning up for sponsors — these ideas have undergirded traditional sports for generations. In e-sports, they are regarded as almost radical.
“They don’t look at themselves as physical human beings,” said Hvidt, who won the European handball championship with Denmark in 2008.
“It’s common sense, in a way. But with them it was not.”

Exercise Meaningful in Having Good Mental Health
In this cross-sectional study, we analysed data from 1 237 194 people aged 18 years or older in the USA from the 2011, 2013, and 2015 Centers for Disease Control and Prevention Behavioral Risk Factors Surveillance System survey. We compared the number of days of bad self-reported mental health between individuals who exercised and those who did not, using an exact non-parametric matching procedure to balance the two groups in terms of age, race, gender, marital status, income, education l... 1 notes

Physiological Decline in the Body When You Stop Exercising
...regular endurance exercise leads to four major consequences:
Increased ability of the heart to eject blood
increased ability of the blood vessels to send blood to where blood is needed
Increased number of capillaries (the vessels that deliver oxygen and ‘food’ to the muscles)
increased size and the number of mitochondria (the “power plants” of the cells).
All these changes lead to the more efficient use of oxygen, as well as nutrients.

Ideal Amount of Exercise for Longevity
People who got some exercise, but not enough to meet the physical activity recommendations were still 20 percent less likely to die over a 14-year period than those who did not do any physical activity. (The recommendations say to do 150 minutes of moderate activity per week or 75 minutes of vigorous activity per week.)
People who engaged in the recommended level of physical activity saw even more benefit: They were 31 percent less likely to die during the study period, compared with those w...

1 Who recommendation is 150 minutes moderate or 75 minutes vigorous a week. Three to five times this amount was linked with a 39% reduction in mortality; therefore, 7.5 hours moderate exercise or 3.75 hours vigorous for best results.

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).
[...]
FIT Treadmill Score = %MPHR 12(M...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 |

| 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
