The purpose of this study is to investigate the beneficial effects of regular exercise and the impact of food supplement carnosine on cognitive, motoric and metabolic functions as well as on specific biologically active substances in volunteers with subjective (SCI) or mild (MCI) cognitive impairment, as well as in patients in early stages of Parkinson's disease. The investigators assume the immediate intervention-associated health benefit for volunteers.
Standard Operating Procedures for patient recruitment, data collection, data management, data analysis routinely used in Biomedical Research Center, Slovak Academy of Sciences, University Hospital Bratislava and Comenius University, Bratislava will be employed. Gait and balance parameters will be examined and analysed at the Department of Behavioural Neuroscience, Centre of Experimental Medicine, Slovak Academy of Sciences, Bratislava, Slovakia Statistical analysis will be employed to address the primary and secondary objectives, as specified in the study protocol.

| Gait parameters (Walking speed) | Walking (gait) speed will be evaluated in a subset of PD individuals with the Azure Kinect depth camera (once the technology for gait analysis will be available to the study investigators). An average walking velocity will be computed as total distance divided by time of the test (m·s-¹); measured using Microsoft Kinect for Azure | 24 months |
| Gait parameter (Stance time) | Stance time will be evaluated in a subset of PD individuals, (once the technology for gait analysis will be available to the study investigators). Stance time - duration within the gait cycle when the measured leg is in contact with the ground. Measured using Microsoft Kinect for Azure as the time from when ankle joint speed in the anterior-posterior direction drops below 10% of its peak to reaching 10% in the next gait cycle, unit measure (s) | 24 months |
| Gait parameter (step length) | Step length - linear distance in the anterior-posterior direction between consecutive heel strikes of opposite feet (m); measured using Microsoft Kinect for Azure as the peak distance between left and right ankle points. In a subpopulation of PD patients after (Azure Kinect) technology is available. | 24 months |
| Postural parameter (magnitude of CoP displacement) | Magnitude of centre of pressure (CoP) displacement - exercise-related changes in CoP magnitude in both anterior-posterior and medial-lateral directions reflecting the whole body sway will be determined with the aid of force platform (mm) | 24 months |
