Ben Greenfield, one of the top biohackers in the U.S. and founder of BenGreenfieldFitness.com, has intriguing insights into health and fitness.

The Benefits of Heart Rate Variability Testing
Heart rate variability (HRV) testing is another biohack Greenfield takes full advantage of. Greenfield prefers an app called NatureBeat, available on both Android and iOS.

“The reason I use that … for self-quantification … is that unlike the ring, it allows me to delve into both sympathetic and parasympathetic nervous system strength (your low frequency or your high frequency power). That allows you to see which element of your nervous system may be affecting your heart rate variability.”

The NatureBeat app also provides special benefits for elite athletes. Greenfield explains:

“There are certain periods of time during the year, especially, leading up to important competitions, where I purposefully sustain a low heart rate variability for a number of days, typically anywhere from three days up to a week. After a week, you really start to see an increase in propensity for injury or illness. That’s called super compensation. Rather than over training, all you’re doing is just a little bit of under recovery, meaning you’re purposefully digging yourself into a bit of a hole …

"Tudor Bompa … wrote some of the better books … on periodization, [which] is based on the concept that you don’t maintain peak fitness all year long …

"If you’re specifically trying to perform [at the cutting] edge, where you’re digging yourself into just a bit of an under-recovery hole, then by allowing yourself a taper after … [you allow your] body to bounce back from that slight amount of over-training. You super compensate. You wind up even more fit than you would have been in the first place.”
