CO2 paste recovery technology — why Brian thinks it beats hyperbaric chambers and cold plunges
At 45:22 · chapter starts 43:14
The recovery technology discussion opens with Kula establishing his non-negotiable foundation: sleep and nutrition come first, everything else is enhancement. From there, he introduces the audience to Air Therapeutics and their CO2 delivery system — a paste applied directly to targeted areas and a full-body suit that replaces oxygen with CO2 for systemic effects. [1] — Brian Kula "Hyperbaric chambers push more oxygen into the body but vasoconstrict, limiting blood flow. CO2 paste does the opposite — it vasodilates and…" 40:54 The mechanism is the Bohr effect: elevated CO2 causes hemoglobin to release oxygen more readily into surrounding tissue, driving improved cellular repair without the need for pressurized environments. Kula contrasts this directly with hyperbaric chambers, which vasoconstrict while pushing in more oxygen — a combination he argues is less effective because more oxygen is only useful if it can be delivered efficiently. He gives personal testimonials (his wife's shoulder recovered in two days, his elbow tendinitis clears reliably) and says he now recommends the paste on hamstrings before max velocity days as a pre-workout enhancement. The conversation then pivots to cold plunges, where Kula takes a notably strong stance: he considers them counterproductive not just for muscle building (where the bodybuilding world has already pushed back) but for neural performance. [2] — Brian Kula "Cold plunges vasoconstrict blood vessels and suppress the nervous system for up to 24 hours — which means an athlete doing a cold plunge th…" 44:56 Cold suppresses the nervous system for up to 24 hours, meaning an athlete who cold-plunges the Friday before a Saturday meet may have a sluggish CNS during competition. He's not anti-cold-plunge entirely — early in the week is fine — but he banned them as pre-competition recovery at his facility once he understood the neural suppression effect. He connects this to the broader theme of the episode: everything Kula recommends is ultimately about optimizing nervous system function and oxygen delivery, because those two systems determine athletic output.
Cold plunges vasoconstrict blood vessels and suppress the nervous system for up to 24 hours — which means an athlete doing a cold plunge the day before a game may actually perform worse. Kula isn't anti-cold plunge entirely, but he's adamant they have no business being used close to competition.
Cold plunges can shut down the nervous system for up to 24 hours, potentially hurting athletic performance if done the day before a game.
ETS Performance, the company that acquired Kula Sports Performance, operates over 80 corporately-owned locations and is targeting becoming the world's largest performance company.
Multi-sport development is ideal through childhood, but Kula acknowledges the real-world pressure of specialization by high school. His pragmatic advice: stay multi-sport through at least freshman year to avoid overuse injuries and build diverse movement patterns, then commit — because in precision sports like baseball, you can't catch up by jumping in late.
