Heat Training Hydration: Protocols for Plasma Volume Expansion
Heat acclimation training can expand plasma volume by 8–12% in 10–14 days, delivering tangible endurance benefits including lower heart rate, improved thermoregulation, and increased VO2max. The hydration protocols used during and after heat sessions determine whether this adaptation is maximised or blunted.

Sauna Use for Endurance Athletes: Plasma Volume, VO2max, and the Post-Exercise Protocol
Post-exercise sauna bathing 4 days per week for 3 weeks increases plasma volume by 7%, run endurance by 32%, and VO2max by 3–4% in trained athletes. Here's the evidence and the exact protocol.

Sodium Loading Before Endurance Races: Protocol, Evidence, and Who Benefits
Sodium loading 24 hours before a race can expand plasma volume by 300–500mL, delay hyponatremia risk, and improve thermoregulatory capacity. But the protocol matters — and it's not right for every athlete or event.
