The American College of Sports Medicine has not formulated a position paper on the ingestion of protein during athletic events. It is a widely accepted understanding that only dietary carbohydrate can contribute to exercise performance.
However, it is also widely understood that at some point in time of any lengthy exercise session that protein ingestion is necessary to forestall and decrease current tissue damage and to promote new tissue and repair. The "trade off" of any protein ingestion being the decrease in gastric emptying times and reduced glucose uptake and glycogen re-synthesis.
Therefore, while it is likely that protein ingestion during any given single exercise session may decrease performance - it is also possible that any such protein ingestion will positively affect future exercise sessions.
Having read the preface to the poll - select the answer to the poll question that comes closest to your own experience and beliefs with regard to protein ingestion during longer term exercise periods.
