What's in PureSport Nutritional Performance Sports Drinks? Whey Protein Isolate is rich in essential amino acids and provides quick muscle recovery Maltodextrin is a complex carbohydrate for long-lasting, sustained energy Sodium replenishes losses due to perspiration Magnesium aids in protein synthesis that helps prevent muscle breakdown Potassium helps keeps body fluids in balance Gluten-Free and Caffeine-Free PureSport Workout - How it works The combination of dextrose and fructose is important because you get a faster rate of carbohydrate uptake into the circulation from the intestines, and possibly a faster rate of muscle carbohydrate uptake. The intestines have several different sugar transporters. There is one for glucose and one for fructose. If you saturate the glucose transporter, providing more glucose will not increase the rate of absorption. However, by providing a different sugar (fructose) you can increase the rate of absorption. The carbohydrate to protein ratio is 2.67 to 1. This provides enough protein to facilitate glucose uptake in muscle without inhibition gastric emptying (movement of drink from the stomach to the intestines). It may also help with maintaining plasma volume during exercise in the heat. When we exercise heat is a by-product of metabolism and this is mainly dissipated by sweating (evaporation). Body water loss causes plasma volume to decline, which can adversely affect performance. It is important to maintain plasma volume. The ingestion of protein along with certain electrolytes such as sodium will help retain plasma volume.

PureSport Recovery - How it works The combination of carbohydrates will accelerate glucose absorption from the intestines and increase rate of muscle glucose uptake for rapid glycogen storage. The additional protein will help with this process by increasing the blood insulin response. The added protein (18g in a 2.67 to 1 ratio) will increase muscle protein synthesis resulting in reduced muscle damage, increased muscle tissue repair and increased training adaptation.

There are a number of studies now that show the benefit of adding protein to a carbohydrate energy drink and recovery drink. The protein added to a energy drink will increase aerobic endurance and reduce muscle damage caused by hard exercise. The protein added to a recovery drink has been shown to increase muscle protein synthesis, to reduce muscle damage, to accelerate the recovery of muscle glycogen stores, to lower the risk of upper respiratory infection, to enhance the recovery process and increase subsequent exercise performance. Consuming the workout drink before and during activity will help keep the individual hydrated, maintain energy, and slow down muscle breakdown. Immediately after exercise or as soon as possible consume the recovery drink, to help replenish muscle glycogen stores, slow down cortisol release, and to rebuild muscles.
