Frontiers in Physiology

And you can't.

So a lovely systematic review that was published in Frontiers in Physiology in July of this year, right, 2026, the time of recording, if you're listening or watching this back now, This looked specifically at athletes who actually require large ranges of motion.

This is relatively niche, right? It's rare that you get studies done on stuff like this.

And that is important for us, and probably you listening, because it included sports and disciplines such as gymnastics, wrestling, swimming, track and field, and crucially... dance, rather than just taking research from general recreational exercises and hoping that it applies to you.

We're relying heavily on a landmark 99 study meta-analysis.

It was published in Frontiers in Physiology, and it looked at the actual physiological efficacy of various recovery tools.

99 studies.

That is huge.

Right.

Studies in the journal Frontiers in Physiology on cutaneous vasodilation looked at how skin blood flow responds to heat.

And what did they find?

Delivering heat in tiny pulses versus a direct continuous step change fundamentally alters how our warm sensory fibers adapt.

And that compartmentalization is actually the problem.

A 2021 paper in the journal Frontiers in Physiology showed that arterial stiffness, which is a major cardiovascular risk factor, is directly related to collagen cross-linking changes in the arterial wall.

The same cross-linking that makes skin less elastic.

That genuinely stopped me when I first read it.
