Okay, so I went to the site just to read through and see what you are going on about…
This is a quote from the clinical study:
"Carbohydrates and fats are the primary fuels metabolized during endurance exercise. However, during prolonged exercise, protein can contribute 5-10% of total energy demands (2, 4) and this contribution can increase under conditions of low glycogen availability (7, 14)."
The results are extrapolated from marathon runner and long distance cyclists.
"In the past few years a number of studies have shown great promise for the role of supplemental protein to improve endurance performance. Ivy et al. (5) compared the effects of consuming varied sports beverages during exercise on cycling time at 85% VO2max following three-hours of varied-intensity, sub-maximal cycling. "
Pitching is not a long, steady game. It is played in explosive bursts followed by periods of little activity. There is nothing in the clinical study to infer the effectiveness of a 4:1 carb to protein ratio in a workout drink outside of extreme endurance sports.
If you plan on running a marathon or competing in a 3 hour bike race, then by all means you should buy this stuff. I just thought we were, you know, referring to pitching and baseball.
