RESULTS PROVEN

HIGH HEAT WORKOUTS = IMPROVED ATHLETIC PERFORMANCE


RAPID Vo2 MAX AND INCREASED OUTPUT AT LACTATE THRESHOLD

Santiago Lorenzo (University of Oregon) recruited 20 highly trained cyclists and had them complete a performance test in temperate conditions on two occasions separated by 10 days. Between the tests, all 20 cyclists completed a prescribed training program. Twelve of them cycled in a controlled, hot environment (100 degrees) while the other eight performed their workouts in temperate conditions (55 degrees) matching those of the performance tests. The 12 cyclists who underwent heat acclimatization improved their performance in the cool performance test by 6 percent. In addition, their VO2max and their power output at lactate threshold increased by 5 percent. There were no improvements among those who trained in a cool environment. -Santiago Lorenzo/University of Oregon, 2010


HEAT TRAINING: SUPERIOR TO ALTITUDE TRAINING

Developing research shows that heat acclimation may be superior to altitude training in eliciting positive physiological adaptations. The research reveals that heat acclimation provides more substantial environmental specific improvements in aerobic performance than altitude acclimation. Athletes more quickly adapt to heat stress to hypoxia meaning heat training not only does a better job at increasing V02 max than altitude, it also makes athletes better at withstanding a wider range of temperatures.  Athletes adapt to heat in one of two ways. The first is through incremental improvements in tolerance over time. The second is through thermo tolerance, which is a cellular adaptation to an extreme heat experience. If you shock your system, your body is able to withstand greater temperature stresses. - Santiago Lorenzo & Chis Minson, Lake Erie College of Osteopathic Medicine


PLASMA VOLUME EXPANSION

In a study published in the European Journal of Applied Physics researchers used elite rowers, and put them through a short protocol: just five days, 90 minutes per day. The rowers were in a room at 40 C and 60% humidity. They rowed at intensity just sufficient to keep their core temperature at a 'modest' overheating level of 38.5 C. The goal was to overheat the rowers, not overwork the. The 5-day acclimation period started two weeks before a major championship race. The result: a 1.5% increase in 2,000m rowing performance. One of the biggest benefits of heat acclimation is plasma volume expansion. Just as altitude stimulates the body to produce more red blood cells, heat stress stimulates it to produce more plasma. The result is a greater cardiac output and higher VO2 at a given effort level. In this study, resting plasma volume increased by 4.5%, even though the athletes had very high plasma volume to start; in the Oregon study, plasma volume increased by 6.5%. - European Journal of Applied Physics, 2010


A 2011 study by a group of researchers in New Zealand found that overall volume of blood plasma increased at a greater rate when athletes did not drink water during exercise.  This type of training can be beneficial because it produces a higher number of “heat shock” protein cells.  -New Zealand researchers
