摘要

研究人员对五名男性和四名女性进行了氮平衡和营养摄入的评估,这些男性和四名女性在进行常规饮食时进行了健身和体重训练,而其中一半的人服用了蛋白质补充剂。补充前的营养素摄入量变化很大,但有些营养素的摄入量低于rda (DHSS, 1979)。补充蛋白质不能显著提高饲粮的营养摄入,因此不能显著提高饲粮的氮摄入量。

Dietary intake and nitrogen balance in athletes with and without consumption of a protein supplement.

Nitrogen balance and nutrient intake were assessed in five males and four females involved in body building and weight training when consuming their habitual diet and whilst half the group were taking a protein supplement. Pre-supplementation nutrient intakes varied greatly but intakes of some nutrients were lower than RDAs (DHSS, 1979). Protein supplementation did not significantly improve nutrient intake, and it was concluded that it is unlikely to improve nitrogen retention because it does not significantly increase nitrogen intake.
