PREPARE TO PERFORM. PreLoad Hydration is ONLY for use before intense efforts, ultra-endurance events or exercise in hot conditions. Not for use during exercise. Osmo PreLoad Hydration is a hyper-hydrator developed based on peer-reviewed science to: - Increase performance during hot and intense efforts - Maximize sustained power - Reduce muscle fatigue Using Osmo Preload Hydration sets the body up for success during high intensity exercise. By boosting your sodium stores and plasma volume before you exercise, you maximize thermoregulation and your performance. Osmo Preload Hydration is a special application product developed for use before hot events, time trials, and high intensity efforts. Preload increases total body water and plasma volume, provides a buffer for lactic acid, and increases the cofactors needed for aerobic metabolism. This allows athletes to optimize their performance in hot conditions and during high intensity activity. For best results, we recommend drinking Preload the night before and the morning of an intense effort. We all know that during exercise, your working muscles produce heat, and your body temperature rises. When your body temperature gets above 103 degrees Fahrenheit, your body systems become compromised - resulting in a precipitous drop in power and performance. What you may not know is that when an athlete begins to feel thirsty, he is already at around a 2% body water loss, which can result in an 11% decrease in top-end power. Your body works to regulate increasing core temperature by moving blood to the skin and offloading heat through sweating. For cooling to work, though, you need to maintain a balance of fluid in your body, so you can sweat properly and maintain your plasma volume. In hot environments and/or during high-intensity efforts, water loss through fast breathing and sweating can be SO rapid that it becomes impossible to replace fluids fast enough to maintain your optimal body water. This drop in body water and the related rise in your core temperature hurts performance. Fortunately Osmo Preload Hydration can prepare you for this through hyper-hydration, which means going into in an event with extra body water. This keeps dehydration and it's related performance losses at bay. There are four primary things that Osmo Preload does to improve performance: First, Osmo Preload increases blood plasma volume, which in turn increases heart-stroke volume, as well as the total volume of blood circulating. This increased circulation allowing your blood to go both to the working muscles AND to the surface to dissipate heat. With greater blood volume, your muscles can function optimally and the heat can dissipate from your skin effectively. Second, since you start the event in a hyper-hydrated state, you have more total body water to support your body's thermoregulatory system. Effectively slowing the rate of core temperature rise, which slows fatigue and maintains power output. Third, Osmo Preload stops cramping by increasing total body sodium stores, eliminating the need to take on additional sodium during long-duration events. Finally, Osmo Preload contains sodium citrate and sodium bicarbonate, which both act as buffering agents. The citrate works to keep aerobic metabolism revved, while the bicarbonate works to buffer lactic acid during intense efforts. And all of this is based on published science. Which is why we say that Osmo Preload Hydration sets the body up for success by boosting sodium stores and plasma volume before hot and high intensity exercise, which both maximize thermoregulation and your performance.
