The Science Behind PureSport and Nutrient Timing™
Human Performance Labs (HPL) develops superior nutritional performance sports drinks with protein for athletes of all types, from world class professionals to club sport amateurs and weekend warriors.
Created by Dr. John Ivy, renowned Chairman of Health and Kinesiology at the University of Texas at Austin, PureSport Workout and PureSport Recovery formulas (patent pending) nutritionally enhance the human body’s performance during and after strenuous athletic activity.
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. |
