Dr. Bill Campbell discusses an evidence-based approach to examine common issues in relation to protein intake for athletes. Bill I. Campbell, PhD, CSCS, FISSN, is assistant professor and director of the Exercise and Performance Nutrition Laboratory at the University of South Florida, a research laboratory dedicated to innovation in sport nutrition research. As a researcher and author, Campbell has published more than 100 scientific abstracts and papers related to sport nutrition and ...
The authors concluded that the aerobic endurance athletes required greater daily protein intakes than sedentary individuals to meet the needs of protein catabolism during aerobic exercise. Ingestion of EAA and protein with carbohydrate after exercise has also reportedly enhanced protein synthesis (Borsheim et al. They concluded that ingestion of whey and casein after resistance exercise resulted in similar increases in muscle protein net balance and net muscle protein synthesis, despite ...
Among competitive female athletes with plasma magnesium concentrations at the low end of the range of normal values, serum total creatine kinase decreased after training in the women supplemented daily with magnesium (360 mg/day for three weeks) compared to the athletes receiving placebo (Golf, Bohmer, and Nowacki 1993). Alterations in dietary magnesium affect magnesium nutrition and performance (Lukaski and Nielsen 2002). Women given a controlled low compared to adequate magnesium intake (...
This section discusses beta-alanine as a sport supplement, beginning with its parent compound carnosine. Elsewhere, Hoffman and associates (2008b) investigated the effect of 30 days of beta-alanine supplementation (4.8 g/day) on resistance exercise performance and endocrine changes in resistance-trained men. Several studies have investigated the effects of supplementing creatine and beta-alanine together (Stout et al.
Ivy and colleagues (2002) instructed cyclists to complete a 2.5-hour bout of intense cycling before ingesting (1) a low-carbohydrate + protein + fat (80 g carbohydrate + 28 g protein + 6 g fat), (2) a low-carbohydrate + fat (80 g carbohydrate + 6 g fat), or (3) a high-carbohydrate + fat (108 g carbohydrate + 6 g fat) supplement immediately after exercise and 2 hours postexercise. Glycogen levels were similar between the two carbohydrate + fat conditions (low carbohydrate and high ...
