colostrum-lean-mass

この研究の注釈：

Supplementation of 60g colostrum daily for eight weeks in otherwise healthy sedentary persons (at least three months of somewhat routine activity) subject to a weight lifting regimen (four times weekly) during the experiment noted that, relative to whey protein, that increases in muscle mass were seen in both groups yet comparable; an exception was total limb circumference and cross sectional area, but the increase in colostrum relative to whey was thought to be due to lower baseline values in the colostrum group.

Supplementation of either 60g whey protein, 60g colostrum, or a combination of 20g colostrum with 40g whey, in elite cyclists over the course of eight weeks noted that performance on a weighted cycling test (similar to Wingate) failed to have any difference between groups (despite all groups improving by about 4% relative to baseline) although in a 2 hour endurance test there was an improvement of 132s and 158s in the colostrum groups (difference not significant) which were both greater than the whey only group at 37s.

In patients with short bowel syndrome, supplementation of colostrum (250mL of a beverage containing 26.5g protein; control of skim milk and protein) for four weeks failed to outperform placebo protein in improving nutritive status and protein absorption and underperformed for increasing weight and lean mass. Power output (assessed by handgrip strength) was not different between groups but increased with protein in general.

Meal-induced GLP-2 secretion was not different between groups.

Eight weeks supplementation of colostrum powder at 60g (three doses of 20g) in elite field hockey players during the beginning of their competitive seasons noted that, relative to the placebo (whey protein), colostrum failed to improve anaerobic cardiovascular exercise (sprints and suicide runs) and did not influence power output.

Lean mass increased with colostrum relative to baseline, but was similar to the increase seen with whey protein.

この研究の注釈：

Supplementation of 20g colostrum daily for eight weeks in active subjects, relative to the placebo of whey protein (20g), appeared to have a slight increase in lean mass (2.3%) without any changes in weight due to nonsignificant decreases in fat mass; whey protein did not have any significant changes relative to baseline. Measurements via DEXA.

Performance parameters including treadmill time to exhaustion, power output, and muscular endurance did not change.
