Effects Of Bovine Colostrum Supplementation On Immune Variables In Highly Trained Cyclists

この研究の注釈:

Supplementation of 10g bovine colostrum (20% Immunoglobulin G) failed to influence neutrophil adhesion factors (CD89) or surface markers on NK cells or lymphocytes. The expected decrease in CD3+CD8+ T cells seen with exercise, however, was attenuated relative to whey protein control resulting in a lesser reduction in the CD4/CD8 ratio associated with intense exercise.

The increase seen in salivary IgA with colostrum failed to reach statistical significance; total IgA and IgE in serum were unaffected. Overall rates of sickness trended to be reduced, but this did not reach significance.


The Nutriceutical Bovine Colostrum Truncates The Increase In Gut Permeability Caused By Heavy Exercise In Athletes

この研究の注釈:

Supplementation of 20g colostrum daily for two weeks prior to a VO2 max training session, relative to placebo, failed to improve physical performance but was able to reduce the increase in intestinal permeability that occurs with high intensity exercise where body heat is elevated.

The increase in GLP-1 seen during exercise in placebo was attenuated with colostrum; other biomarkers (serum NPY, VIP, or ghrelin) were not affected.


Bovine Colostrum Supplementation During Running Training Increases Intestinal Permeability

この研究の注釈:

Supplementation of 60g bovine colostrum (immunoglobulin content not disclosed) daily for eight weeks alongside thrice weekly aerobic training noted that, when subject to a 30 minute run to exhaustion, that colostrum was associated with an increase in intestinal permeability without any overt gastointestinal side effects.

No performance parameter was increased with supplementation.

Bovine Colostrum Supplementation During Endurance Running Training Improves Recovery, But Not Performance

この研究の注釈:

Supplementation of colostrum for eight weeks (60g, containing 2mg/kg IGF-1) in otherwise healthy mildly active adult males with whey protein as placebo noted that colostrum failed to influence performance on a treadmill running test (approximately 30 minutes) or biochemical parameters in the blood. Plasma IGF-1 was not different between groups.
