Objective of the study was to determine the effectiveness of the technology of biocontrol of a virtual object on a stabilometric signal for the optimization of the motor-cognitive capabilities of the 10-12 year-old orienteering athletes.
Methods and structure of the study. Sampled for the study were 14 orienteering athletes aged 10-12 years (boys at the 1st year of the sport specialization stage) at the preparatory stage of the annual training process. The present biocontrol technology was focused on the support reaction training on the stabilometric platform with biological feedback and evaluation of the motor-cognitive capabilities using electromyography and psychophysiological testing methods.
Results and conclusions. The results of the daily support reaction training on the stabilometric platform over five training sessions showed that the total amplitude of electromyogram and coefficient of synergy with the lower limb muscles (m. rectus femoris, m. biceps femoris of the right and left leg) increased at the end of training, which suggested the improved intramuscular coordination. In turn, the results of a number of psychophysiological tests indicated a statistically significant reduction in the sensorimotor response time, an increase in the level of lability and endurance of the nervous system, and an increase in the volume, selectivity, and set-shifting of attention, which expanded the cognitive capabilities of the 10-12 year-old orienteering athletes.

Keywords: biocontrol, stabilometry, motor-cognitive capabilities, sport orienteering, 10-12 year-old athletes.
