ce (RDA) for men over 19 years of age is 0.86 grams per kilogram (6:767). However, no additional allowance is made for individuals who engage in physical activity. It has been widely recognized though that both endurance and strength exercise may increase a person's protein requirements. Williams (1985), for example, estimated that the synthesis of 1 lb muscle per week requires a daily average intake of 14 grams of protein. In addition, other researchers have demonstrated that intakes exceeding 2 grams per kilogram are required in order to maintain a positive nitrogen balance in some weight-trained individuals (2:97). In general, the suggested protein intakes for bodybuilders range widely: from just above the RDA, to as high as four times the RDA. Data gathered by Lemon et al. (1992) seems to indicate that dietary protein needs are approximately 100% greater than the RDA during the early stages of an intensive bodybuilding program. Nonetheless, the study further observed that protein increases from 1.35 to 2.62 grams per kilogram per day do not enha
