What is 'Fitness' ?
What is “Fitness” ?
Another great podcast listen today. Bulletproof Exec # 26 with book “Body by science” by author Dr. Doug McGuff
Here’s the link: Body by Science
The following caught my attention:
“Anabolic vs. Canabolic state - Fitness is physiological headroom - output above a rest baseline - stress to create adaptive change - Analabolic bringing in nutrition - Canabolic introducing stress . Sleep vs. wakefulness . Exercise vs. Recovery”
In addition, the topic of Heart Rate variability (HRV) came up again especially with:
Cardiac Output - Increase in Stroke volume not beats - Maintaining Beat to Beat - Stroke volume goes up- How much blood fills the heart. Time between beats. Heart beats HARDer not Faster.
Heart Plastisity demands in a short period of time equates to Cardic Health. Trained the plasticity of intervals.
Studies have shown Endurance athletes issues with atriole fibration.
INTERVALS! INTERVALS !
Lower variability is shown by HeartMath Scientist: Roland McCreedy -> HEART MATH
Furthermore, 1-minute intervals are also shown to affect aerobic metabolism which is the ability to have the mitochondria fuel feeding.
Start with Glycolysis which converts to Pyruvate .
Anabolic - Lactate = Lactic Acid .
Heart is tuned into the TOTAL cell not just Mitochondria.
Aerobic = Cardio is FALSE !!
