The Influence Of Bovine Colostrum Supplementation On Exercise Performance In Highly Trained Cyclists

この研究の注釈:

Bovine colostrum (10g of 20% immunoglobulins) daily for five weeks prior to a 40km time trial increased performance relative to whey control in a somewhat ambiguous manner in elite cyclists, but continuing supplementation for another week of high intensity training before another 40km time trial noted significant improvements in overall performance, intensity (VO2max), and heart rate relative to whey control which was more pronounced in faster athletes.

The ventilatory threshold, which decreased by 14.6+/-19.2% in control, was preserved to 2.2+/-15.7% of baseline value in the colostrum group; peak power output was not influenced at any time.


Dose Effects Of Oral Bovine Colostrum On Physical Work Capacity In Cyclists

この研究の注釈:

Supplementation of either 60g whey protein, 60g colostrum, or a combination of 20g colostrum with 40g whey, in elite cyclists over the course of eight weeks noted that performance on a weighted cycling test (similar to Wingate) failed to have any difference between groups (despite all groups improving by about 4% relative to baseline) although in a 2 hour endurance test there was an improvement of 132s and 158s in the colostrum groups (difference not significant) which were both greater than the whey only group at 37s.


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.

Oral Bovine Colostrum Supplementation Enhances Buffer Capacity But Not Rowing Performance In Elite Female Rowers

この研究の注釈:

60g colostrum daily in elite female rowers daily for nine weeks, relative to whey protein as control, appeared to reliably increase blood buffering capacity (assessed by the relationship between lactate and pH) but this buffering capacity was not associated with performance on rowing tests and the actual performance on rowing tests was not affected by 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.
