The aim of this study was to investigate the potential beneficial effects of dietary anserine and carnosine (CRC) supplementation on cognitive functioning and physical activity of the elderly. The fifty-six subjects (65+) were allocated to the CRC group or placebo group at a 1:1 ratio. The double-blind procedure was used. Data were collected at the baseline and after 13-weeks of supplementation. In the follow up procedure fifty one subjects took part. Chicken meat extract (CME) containing 40% of CRC components (2:1 ratio of anserine to carnosine) was administered 2.5 g per day which allowed to rich the level of 1 g CRC in dipeptides supplement. The cognitive function, physical capacity, body measurements, blood pressure and heart rate (HR) were assessed. After supplementation Body Mass Index (BMI) decreased significantly (p < 0.05) in the CRC group performance comparing the placebo group. In two of six Senior Fitness Test the scores increased significantly (p < 0.05) in CRC group comparing to the placebo group. The perceived exertion differed significantly (p < 0.05) at the baseline and after follow up at the CRC group. The mean values of the Short Test of Mental Status (STMS) scores showed the significant (p < 0.04) increase only in CRC group, in the subscores of construction/copying, abstraction and recall. Conducted anserine and carnosine supplementation in the elderly brings promising effects on cognitive functioning and physical capacity of participants. However, further studies are needed.
