Document Summary
Ergogenic aids: external aid that can enhance performance (steroids, special material on bike) Whey: fast digesting vs. casein: slow digesting. Meet daily protein requirements (1. 0 2. 0 g/kg/day depending on duration, intensity, adaptation to training) Protein synthesis is increased after training ( fast proteins combined with high gi cho"s ((glycemic index carbohydrates)) result in the largest spikes) Milk as a post-workout drink: lactose = high gi cho: potential benefits protein from whey. People with limited access to quality protein sources. Athletes requiring high protein and calorie intakes easier to drink calories than eat them. Liquid may be more palatable after strenuous exercise than whole foods. Elderly, or others who have problems with chewing, still need protein: drawbacks. Some nutrients removed during processing b vitamins, iron, other vitamins/minerals. Easier to over consume protein: creatine. Creatine phosphate provides energy for activities lasting < 10 seconds. Definitely: increases energy stores in muscles for short, intense activities.
