BOVINE COLOSTRUM & ATHLETIC PERFORMANCE/ANTI-AGING

BOVINE COLOSTRUM ATHLETIC PERFORMANCE

Bovine Colostrum & Athletic Performance/Anti-Aging

Davison G. The Use of Bovine Colostrum in Sport and Exercise. Nutrients. 2021 May 24;13(6):1789. This review article highlights the last 25 years of research into the interest in and use of bovine colostrum within sports nutrition. Such studies have investigated the effects of colostrum on body composition, physical performance, recovery, gut damage and permeability, immune function, and illness risk.

Davison G, Jones AW, Marchbank T, Playford RJ. Oral bovine colostrum supplementation does not increase circulating insulin-like growth factor-1 concentration in healthy adults: results from short- and long-term administration studies. Eur J Nutr. 2020 Jun;59(4):1473-1479. The World Anti-Doping Agency advises athletes against taking colostrum for fear of causing increased plasma IGF-1. There are also concerns that colostrum may theoretically stimulate malignancy in organs which express IGF-1 receptors. Ingestion of standard recommended doses of colostrum does not increase IGF-1 levels in healthy adults, providing additional support for the safety profile of colostrum ingestion.

Eur J Nutr. 2019 Feb;58(1):335-344. Bovine colostrum blunts the prolonged exercise-induced decrease in clinically relevant in vivo immune responsiveness to a novel antigen, which may be a mechanism for reduced illness reports observed in the previous studies.

Główka N, Woźniewicz M. Potential use of Colostrum Bovinum supplementation in athletes – A review. Acta Sci Pol Technol Aliment. 2019 Apr-Jun;18(2):115-123. Although the health properties of colostrum are not fully understood, its supplementation in athletes has been particularly interesting for over 20 years. The presence of growth factors, immunoglobulins, cytokines, lactoferrin and hormones suggests that colostrum may improve the functioning of the digestive, immune and neuroendocrine systems, and exercise performance. The administering of colostrum seems to be most effective during periods of high intensity training.

Kotsis Y, Mikellidi A, Aresti C, Persia E, Sotiropoulos A, Panagiotakos DB, Antonopoulou S, Nomikos T. A low-dose, 6-week bovine colostrum supplementation maintains performance and attenuates inflammatory indices following a Loughborough Intermittent Shuttle Test in soccer players. Eur J Nutr. 2018 Apr;57(3):1181-1195. Post-exercise exercise-induced muscle damage may be reduced and performance better maintained by a low dose of bovine colostrum administration following Loughborough Intermittent Shuttle Test in soccer players.

Int J Sport Nutr Exerc Metab. 2014 Jun;24(3):276-85. Colostrum supplementation during resistance training was beneficial for increasing leg press strength and reducing bone resorption in older adults. Subjects taking colostrum improved upper body strength, muscle thickness, lean tissue mass, and cognitive function.

Shing CM, Peake JM, Suzuki K, Jenkins DG, Coombes JS. A pilot study: bovine colostrum supplementation and hormonal and autonomic responses to competitive cycling. J Sports Med Phys Fitness. 2013 Oct;53(5):490-501. Bovine protein concentrate supplementation maintained salivary testosterone concentration and modulated autonomic activity over consecutive days of competitive cycling.

Am J Physiol Gastrointest Liver Physiol. 2011 Mar;300(3):G477-84. Bovine colostrum may have value in enhancing athletic performance and preventing heat stroke by halting the normal increase in gut permeability with heavy exercise.

Davison G, Diment BC. Bovine colostrum supplementation attenuates the decrease of salivary lysozyme and enhances the recovery of neutrophil function after prolonged exercise. Br J Nutr. 2010 May;103(10):1425-32. Bovine colostrum supplementation either speeded the recovery (neutrophil function) or prevented the decrease (salivary lysozyme) in these measures of innate immunity. These results suggest that 4 weeks of bovine colostrum supplementation limits the immune-depressive effects induced by an acute prolonged physical stressor, such as exercise, which may confer some benefits to host defense.
ABSTRACT

Shing CM, Hunter DC, Stevenson LM. Bovine colostrum supplementation and exercise performance: potential mechanisms. Sports Med. 2009;39(12):1033-54. A review of studies investigating the influence of bovine colostrum supplementation on exercise performance suggests that bovine colostrum supplementation is most effective during periods of high-intensity training and recovery from high-intensity training, possibly as a result of increased plasma IGF-1, improved intramuscular buffering capacity, increases in lean body mass and increases in salivary IgA.

Shing CM, Jenkins DG, Stevenson L, Coombes JS. The influence of bovine colostrum supplementation on exercise performance in highly trained cyclists. Br J Sports Med. 2006 Sep;40(9):797-801. Low dose bovine colostrum protein concentrate supplementation elicited improvements in 40km time trial performance during a high intensity training period and maintained ventilatory threshold following five consecutive days of high intensity training.

Crooks CV, Wall CR, Cross ML, Rutherfurd-Markwick KJ. The effect of bovine colostrum supplementation on salivary IgA in distance runners. International Journal of Sport Nutrition and Exercise Metabolism 2006;16(1):47-64. Twelve weeks of bovine colostrum by male and female distance runners increased secretory IgA levels in saliva (s-IgA). This population has a higher risk of upper respiratory tract infections (URTI) and s-IgA is a potential mucosal immune correlate for URTI. Median levels of s-IgA increased by 79% in the colostrum group after 12 weeks compared to placebo.
ABSTRACT

Brinkworth GD, Buckley JD, Slavotinek JP, Kurmis AP. Effect of bovine colostrum supplementation on the composition of resistance trained and untrained limbs in healthy young men. Eur J Appl Physiol. 2004 Jan;91(1):53-60. Either bovine colostrum or whey protein was given to young men who were either in training or not in training. Those in the training group who received colostrum showed a significantly greater increase in both upper arm circumference and cross-sectional area compared to those receiving whey, while those who were not in training showed no change.
ABSTRACT

Buckley JD, Brinkworth GD, Abbott MJ. Effect of bovine colostrum on anaerobic exercise performance and plasma insulin-like growth factor I. J Sports Sci. 2003 Jul;21(7):577-88. Athletes in training were given either bovine colostrum or placebo for 8 weeks. Those receiving colostrum showed a significant increase in peak anaerobic power over placebo. Bovine colostrum supplementation during training had no effect on plasma IGF-I.

Colostrum supplementation in elite field hockey players, both male and female, resulted in improved sprint performance over whey placebo; no differences were observed with regards to body composition or endurance performance.
