Berk LS, Nieman DC, Youngberg WS, Arabatzis K, Simpson-Westerberg M, Lee JW, Tan SA, Eby WC. The effect of long endurance running on natural killer cells in marathoners. Medicine and Science in Sports and Exercise. 22(2):207-212 (1989). Natural killer cells are lymphocytes which are specialized to seek out and kill foreign cells or infected host cells in a nonspecific manner.  They are important in both immunity and the body’s ability to eliminate cancerous cells before they become dangerous.  Studies were done on ten experienced marathon runners to see the effects of exercise on natural killer cell activity.  Natural killer cells were identified by means of surface markers characteristic of these cells.  Following three hours of exercise, natural killer cell activity was found to be markedly decreased at 1.5 and 6 hours post-exercise (as compared to pre-exercise levels), but at 21 hours the levels had returned to the pre-exercise levels.  This could indicate an increased susceptibility to infection following strenuous exercise.

Buckley JD, Abbott MJ, Brinkworth GD, Whyte PB. Bovine colostrum supplementation during endurance running training improves recovery, but not performance. Journal of Science, Medicine and Sport 5(2):65-79 (2002). Supplementation with colostrum did not increase plasma IGF-1 levels or improve performance during an initial bout of running. However, performance during a second bout of exercise may be improved by as much as 5.2% in the average subject after 8 weeks of colostrum supplementation, possibly due to an enhancement of recovery.

Burke ER.  Colostrum as an Athletic Enhancer and Help for AIDS.  Nutrition Science News, May, 1996.  A review article which discusses the role of colostrum in athletics as well as its benefits for AIDS patients.  With regard to athletics, the article focuses on the roles of growth hormones, specifically insulin-like growth factor (IGF-1), as well as epidermal growth factor (EGF), platelet-derived growth factor (PDGF) and transforming growth factor beta (TGF-β), in relation to muscle development in athletes.  It also discusses colostrum’s effect on leaky gut syndrome, a common problem in the general population, but of particular concern to athletes who perform at their best when they can utilize all the nutrients they take in.  It is hypothesized that “sealing” the leaky gut would increase energy levels and smooth out performance, especially for those athletes who experience irritable bowel syndrome as a result of incomplete digestion due to protein supplementation.

Leppäluoto, A, et al. Bovine colostrum supplementation enhances physical performance on maximal exercise tests2000 Pre-Olympic Congress Sports Medicine and Physical Education, International Congress on Sport Science, Brisbane, Australia.  The effect of colostrum supplementation on maximal oxygen uptake and flight times in jump tests was studied in 10 young athletes in a double-blind placebo study.  After 12 days, oxygen uptake in the placebo group declined 7% while remaining steady in the colostrum group.  Flight times declined for the placebo group in the counter movement and squat jumps while remaining the same or only slightly less for the colostrum group.  The results indicate that colostrum supplementation improves running and jumping performance in young athletes.

Lycholat, T. Dairy colostrum: the new creatine?  FitPro Magazine, August/September, 2003.  www.fitpro.com Despite limited research on the benefits of colostrum supplementation, enough evidence has been produced by various independent laboratories to support the hypothesis that colostrum can promote small but significant and lasting improvement in work capacity and faster recovery as well as the ability to increase non-fat body mass coupled with the lack of doping results make colostrum a very attractive choice for the serious athlete.

Protein metabolism and strength performance after bovine colostrum supplementation.  Amino Acids 28(3):327-335 (2005). The study was designed to determine the response of muscle protein, serum amino acids and strength performance to supplementation with bovine colostrum.  A rest group and an exercise group were further broken down into experimental and control subjects.  Experimental groups received 20 grams of colostrum per day for two weeks, while the control groups received 20 grams of maltodextrin per day as a placebo.  In the exercise experimental group, serum amino acid levels increased as did muscle protein synthesis and breakdown (compared to placebo), but no difference in strength performance, indicating that while colostrum supplementation did not lead to greater strength performance, it did promote recovery after exercise.

Shing CM, Jenkins DG, Stevenson L, Coombes JS. The influence of bovine colostrum supplementation on exercise performance in highly trained cyclists.  British Journal of Sports Medicine 40(9):797-801 (2006).  29 highly trained male road cyclists underwent preliminary testing for 7 days, including a VO(2max) test to determine ventilation threshold, a time to fatigue test at 110% of ventilation threshold, and a 40 km time trial.  The group was then divided into an experimental group which received 10 grams of bovine colostrum protein concentrate (CPC) per day and a placebo group which received 10 grams of whey protein concentrate per day.  Both groups resumed their normal training regimen for 5 weeks.  They were then retested and underwent 5 days of high intensity training and again retested.  The effect of CPC supplementation during normal training showed no significant difference compared to placebo, but after the period of high intensity training there was a significant increase in all performance measurements, time trial performance, time trial intensity (% VO(2 max)), and heart rate during the time trial.  CPC supplementation also prevented a decrease in ventilatory threshold during the high intensity training period.

Effects of bovine colostrum supplementation on immune variables in highly trained cyclists.  Journal of Applied Physiology 102(3):1113-1122 (2007). 29 highly trained road cyclists completed a 40 km time trial and then were separated in experimental and placebo test groups.  The experimental group was given 10 grams of  bovine colostrum protein concentrate (CPC) per day, and the placebo group received 10 grams of whey protein concentrate per day.   After 5 weeks of supplementation, the riders were retested on the 40 km course.  Then they received 5 days of high intensity training and completed a final 40 km time trial.  Blood samples were collected before and after each time trial and tested for various immune variables.  Upper respiratory illness (URI) symptoms were recorded over the entire experimental period.  Compared to the placebo group, the experimental group which received the CPC significantly increased pre-exercise tumor necrosis factor (TNF) receptor 1.  Supplementation with CPC also significantly suppressed the decrease in cytotoxic/suppressor T cells commonly seen in athletes post-exercise.  Those in the experimental group also demonstrated a trend towards a reduced incidence of URI symptoms.  In summary, CPC supplementation modulates immune parameters during normal training and after an acute period of intense exercise, which may contribute to lower URI incidence.
