PreLoad Hydration

Osmo's new PreLoad Hydration formula was developed specifically for use prior to hot events, time trials, and other high intensity workouts. PreLoad works to increase total body water and plasma volume, provides a buffer for lactic acid, and increases the cofactors needed for aerobic metabolism.


To break down exactly how PreLoad works, Dr. Stacy Sims, Osmo Nutrition's chief research officer, explains the processes that occur within the body during exercise. As you work out, body temperature rises due to the heat produced from working muscles. When body temperature rises above 102 degrees Fahrenheit, many of the body's systems are compromised, resulting in a steep drop in power output. For example, when athletes begin to feel thirsty, they are already at about a 2 percent body water loss, which can result in an 11 percent decrease in top end power.


To maintain proper function, the body works to regulate core temperature by moving blood to the skin and offloading heat through vasodilation and evaporative cooling -- also known as sweating. This system is effective, but requires continual replenishment. In hot environments, and during high intensity efforts, body water loss through respiration and perspiration can be so rapid that it becomes impossible to replace fluids fast enough to maintain optimal body water.


Fortunately, we can prepare by 'hyperhydrating' -- effectively going into an event with extra body water, or spare tank, keeping dehydration and the related performance losses at bay. This is where Osmo PreLoad Hydration comes in, as there are several primary actions PreLoad does to improve output levels. The initial thing Osmo does is increases blood plasma volume, which means that the total volume of blood circulating through the body is increased. This increased circulation reduces the compromise blood usually makes in hot conditions to go to the working muscles and to the surface to dissipate heat. With greater blood volume, both the metabolism of the muscles and heat dissipation at the skin surface can occur effectively.


Additionally, since athletes start their exercise in a hyperhydrated state, they have a greater amount of total body water to increase the effectiveness of the body's thermo-regulation system. This works to slow the rate of core temperature rise, which then slows fatigue and power decline. Because of this hyperhydration state the athlete starts in, PreLoad also stops cramping by increasing total body sodium stores, which eliminates the need to take on additional sodium during long duration events. Finally, PreLoad contains sodium citrate and sodium bicarbonate, both of which act as effective buffers. The citrate works to keep aerobic metabolism high, whereas the bicarbonate works to buffer lactic acid during the intense efforts.


Overall, PreLoad sets the body up by 'planning ahead' -- boosting sodium stores and plasma volume before exercise. This maximizes both thermo-regulation and overall output levels. For best results, Osmo recommends consuming PreLoad the night before and morning of an effort requiring maximum hydration and metabolic buffering.


The Osmo Nutrition PreLoad Hydration is available in one 20oz container and in the flavor Pineapple & Lemon.
