Athletes will go to excessive lengths to spice up efficiency. Powerlifters devour hundreds of energy for a unclean bulk to hit their weight class for the subsequent meet. Cyclists deprive themselves of caffeine, solely to load up with a large dose proper earlier than a race for a efficiency increase. Now, distance runners are leaping in with their very own stunning tactic: utilizing saunas to enhance their time to exhaustion, all to keep up—and even surpass—their race occasions.
In a research printed in the Journal of Science and Drugs in Sport, researchers adopted six male distance runners over a three-week interval. Throughout this time, the runners underwent three weeks of post-training sauna classes and three weeks of management coaching, with a three-week washout interval.
In the course of the sauna part, the runners sat in a moist sauna at 89.9°C for 31 minutes after every coaching session, averaging round 12.7 classes. Earlier than and after every sauna session, the individuals accomplished a treadmill run for about quarter-hour or till exhaustion, at their present greatest 5k race tempo. Additionally they measured blood markers like plasma and red-cell quantity.
The researchers concluded that sauna use elevated the time to exhaustion by 32%, which corresponds to a 1.9% enchancment in endurance. Plasma and red-cell quantity additionally elevated by 7.1% (5.6-8.7%) and three.5% (-0.8% to eight.1%).

Researchers consider that the elevated blood quantity that developed over the three weeks of post-exercise sauna bathing was answerable for the considerably enhanced endurance efficiency.
In 2020, a research printed within the European Journal of Utilized Physiology confirmed the identical. On this research, researchers adopted 20 educated middle-distance runners. The runners had been cut up into two teams: one group who continued their regular coaching routine and one other who added sauna classes at round 101–108°C, 5–10% humidity post-workout. The sauna group continued their sauna classes for about 28 minutes, thrice per week, for 3 weeks.
Earlier than and after the coaching interval, all individuals accomplished a number of assessments, together with one to measure their warmth tolerance throughout a run, a VO2max take a look at to measure cardio capability, and a lactate threshold take a look at.
On the finish of the research, researchers found that not solely did the sauna classes enhance the athletes’ warmth tolerance and lactate threshold, but in addition improved their VO₂ max by 0.27 L/min.
The underside line? Sauna classes do greater than rev your metabolism and help coronary heart well being—they could additionally make it easier to maintain your tempo longer when it counts most on race day.
