The purpose of
this study was to determine the effect of 8 wk of bovine colostrum
supplementation on body composition and exercise performance in active
men and women. Subjects were randomly assigned to a placebo (whey
protein) and colostrum group (20 g/d in powder form). Each subject
participated in aerobic and heavy-resistance training at least three
times per wk. Body composition was assessed via dual x-ray absorptiometry
analysis. Treadmill time to exhaustion, one repetition maximum strength
(bench press), and the total number of repetitions performed during
one set to exhaustion at a submaximal load for the bench press (50%
and 100% of body weight for women and men, respectively) were ascertained.
The whey protein group experienced a significant increase (P <
0.05) in body weight (mean increase of 2.11 kg), whereas the colostrum
group experienced a significant (P < 0.05) increase in bone-free
lean body mass (mean increase of 1.49 kg). There were no changes in
any of the other parameters measured. Thus, supplementation with bovine
colostrum (20 g/d) in combination with exercise training for 8 wk
may increase bone-free lean body mass in active men and women.
