Antonio, J, et al. The effects of bovine colostrum supplementation on body composition and exercise performance in active men and women. Nutrition 17(3):243-247 (2001). Actively training male and female athletes were given colostrum supplementation or placebo for a period of 8 weeks. Subjects receiving colostrum but not placebo showed an increase in lean body mass.

Brinkworth, GD, et al. Effect of bovine colostrum supplementation on the composition of resistance trained and untrained limbs in healthy young men. European Journal of Applied Physiology 9(11):53-60 (2004). Either bovine colostrum or whey protein were given to young men who were either in training or not in training. Those in the training group who received colostrum showed a significantly greater increase in both upper arm circumference and cross-sectional area compared to those receiving whey, while those who were not in training showed no change.

Buckley, JD, et al. Effect of bovine colostrum on anaerobic exercise performance and plasma insulin-like growth factor I. Journal of Sports Science 21(7):577-588 (2003). Athletes in training were given either bovine colostrum or placebo for 8 weeks. Those receiving colostrum showed a significant increase in peak anaerobic power over placebo.

Crooks, C, et al. Bovine colostrum supplementation increases levels of s-IGA in distance runners: a study based on athletes in training for the 2002 Rotorua marathon. Unpublished research. Marathon runners in training were given bovine colostrum or placebo for 12 weeks in a double blind study. Those in the colostrum group showed significantly more secretory IgA (s-IgA) in their saliva than either the placebo group or sedentary controls. The colostrum group also reported a significantly lower rate of upper respiratory infections (URI) during this period.
