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.
