Fig. 4From: Effects of protein intake prior to carbohydrate-restricted endurance exercise: a randomized crossover trialArterial phenylalanine enrichment at baseline (BL), during 90 steady state exercise (90ss) and bed rest recovery (BR) with PLA or WPH ingestion. Values are means ± SD (n = 9); P < 0.05. Means within each trial with different subscripts are significantly different from each other; WPH subscripts are in cursive. # Significant difference between PLA and WPH at each respective timepointBack to article page
