bovine colostrum whey protein ...Study Participants
40Bovine colostrum is the initial milk secreted by cows during the first day after calving. Colostrum is high in protein and contains a number of substances that have potential to be beneficial for the immune system. Preliminary studies about effects of colostrum supplementation show its potential for increasing human exercise performance; however, more evidence across the lifespan is required to confirm effects and to understand mechanisms of action. The objectives are to determine the effect of 8 weeks of bovine colostrum supplementation, compared to whey protein supplementation on the following dependent variables in men and women 50 years and older while participating in a resistance-training program:
muscle mass
strength
blood levels of growth factors and markers of inflammation
urine levels of muscle and bone catabolic markers
tests of cognitive ability It is hypothesized that bovine colostrum supplementation will result in greater increases in muscle mass, strength, blood IGF-1 levels (an anabolic hormone), and cognitive ability, and greater reductions in inflammation, and markers of muscle and bone catabolism, compared to placebo.
60 g/d bovine colostrum in powder form to be mixed with drinks. The dose will be spread out 3 times per day (20 g per dose)
60 g/d whey protein powder mixed into drinks. It is to be divided into 3 daily doses (20 g per dose)
Inclusion Criteria: Men or women 50 y or older Exclusion Criteria: Milk allergies Contraindications to exercise as indicated by the Physical Activity Readiness Questionnaire
