More from this paper
- Total antioxidant capacity was significantly higher during the low-GI diet compared to the high-GI diet under fasting conditions, with total ORAC values of 11,736 +/- 668 vs. 10,381 +/- 612 micromol Trolox equivalents/l (P = 0.002).Strong
- The area under the postprandial response curve for total ORAC and PCA-ORAC differed significantly between the low-GI and high-GI diets.Strong

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
