Osmo Preload Hydration for Women was specifically developed for female athletes and to be used prior to hot events, time trials, long duration and high intensity efforts. Preload for Women increases your total body water and plasma volume, supplies key buffering agents for anaerobic and aerobic metabolism, and has branched-chain amino acids to delay fatigue and expand total body water. 

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. 

Female athletes face greater challenges with regard to body water and sodium losses in these environments simply because estrogen shifts fluid from the blood–dropping plasma volume by 8%. Additionally, progesterone decreases sodium in the body, which also reduces the fluid women need—to cool the core, and to get blood to working muscles. Starting exercise with a reduced plasma volume as well as less sodium affects blood circulation as well, and women are apt to lose power due to reduced circulation sooner than their male counterparts. 

There are three primary things that Osmo Preload for Women does to improve the performance of female athletes: 

First, the sodium and extra fluid in Preload for Women increases plasma volume and sodium stores, which in turn increases heart-stroke volume blood circulation. This increased circulation allows your blood to go both to the working muscles AND to the surface to dissipate heat. With greater blood volume, your muscles can metabolize properly and the heat can dissipate from your skin at the same time. 

Second, since an athlete starts an event in a hyper-hydrated state, she has more total body water to support the body’s thermoregulatory system. Effectively slowing the rate that her core temperature rises, which slows fatigue and enables her to maintain power. 

Third, the branched-chain amino acids, or BCAA’s, in Preload for Women, helps delay central nervous system fatigue and expand total body water. 

The BCAA’s also set up the body to have an elevated amino acid profile towards the end of exercise, reducing the muscle breakdown effects of progesterone and jumpstarting muscle synthesis, a key aspect of rapid recovery. 

In short, using Osmo Preload Hydration for Women before strenuous exercise sets the body up for success during exercise by boosting sodium stores, maximizing blood volume and circulation, and reducing central nervous system fatigue. The addition of BCAA’s help reduce the breakdown effect of progesterone by circulating amino acids, which allow you to recover more quickly.
