Twelve-Week Colostrum Bovinum Supplementation Supports Aerobic Capacity but has No Effect on Body Composition in Endurance-Trained Males: A Randomized Placebo-Controlled Crossover Study

Popis výsledku v původním jazyce

Twenty-eight endurance-trained males aged 31.1 +/- 10.2 years (body mass [BM] 81.9 +/- 9.0 kg) completed this randomized double-blind placebo (PLA)-controlled crossover study investigating the effect of 12-week Colostrum Bovinum (COL) supplementation (25g(COL)&lt;middle dot&gt;day(-1)) on aerobic fitness and capacity, time to exhaustion, BM and body composition (BC), and blood lactate concentration. There were four main-before/after supplementation study visits (COLPRE and COLPOST; PLA(PRE), and PLA(POST)). During study visits, BM and BC evaluation, incremental rowing test (IRT) to exhaustion, and evaluation of resting (REST) and post-exercise (POST-IRT) blood lactate concentration were performed. COL, but not PLA supplementation, significantly increased (p &lt; 0.05) time to ventilatory threshold (T-VT). Moreover, the implemented treatments had large (mL&lt;middle dot&gt;min(-1)) and moderate (mL&lt;middle dot&gt;min(-1)&lt;middle dot&gt;kg(-1)) effects on oxygen uptake at VT (VO2VT), as well as moderate effect on power output at VT (P-VT; W&lt;middle dot&gt;kg(-1)) with the highest values observed at COLPOST visit. Neither significant influence of COL supplementation on time to exhaustion (T-EXH) in IRT, BM, and BC on blood lactate was observed. Importantly, there were significantly (p &lt; 0.05) higher increases in VO2VT (mL&lt;middle dot&gt;min(-1) and mL&lt;middle dot&gt;min(-1)&lt;middle dot&gt;kg(-1)) after COL compared to PLA supplementation. In summary, COL supplementation resulted in a favorable increase in T-VT, and tended to improve some of the evaluated threshold indicators, namely VO2VT and P-VT in endurance-trained male athletes during IRT. Therefore, COL supplementation may be considered as a support to improve aerobic fitness and capacity in endurance-trained males; however, supplementation strategy must be personalized and properly incorporated into the individual training.
