Every athlete knows that the absolute requirement for performance is energy. The weightlifter, sprinter, swimmer and marathon runner relies on adequate energy for high power output. Although cardiovascular and respiratory requirements are important for endurance athletes, fuel supply to the muscles is essential for optimal performance. Two important requirements by muscles to perform are protein and energy. The food we eat supplies protein to build the structural components and the basic substrate for conversion to energy for muscle cells. The major source of chemical energy for not just muscle cells but nearly all cells in the body is adenosine triphosphate ATP. When ATP levels decrease in muscles, there is no energy to fire the structural machinery, no matter how much protein is provided. This is commonly experienced as fatigue. Thus, the most important consideration for endurance athletes is to renew ATP supplies. more... Packing Information: These powders are reduced down from kilo
