Course load during the academic classes in the medical school is to stress factors for students with low stress tolerance. The study involved 30 student volunteers, a second-year at the age of 18-20 years diagnosed with psychophysiological tests low stress tolerance. Psychophysiological indicators of students tested at the beginning and at the end of the training session, were the basis for the analysis of the behavior of quasi-attractors parameters of the state vector of the human body (VSOCH) in m-dimensional phase space. In the phase space of dimension 7 included: situational anxiety, mood, activity, mood (SAN), the total deviation from the norm of autologous, stress, vegetative factor (M. Lusher test). In the phase space dimension of 10 included 10 parameters proofreading tests for attention and visual perception. In order to reduce psychological stress for students asked to perform a 60 min interval of three physical exercises (squat, lifting arms biceps and calf muscles) to 30 seconds on each machine for rehabilitation Power Plate with intense activation of the proprioceptive sensory system with a frequency of 30 Hz and acceleration platform 18 m/s2.

According to the analysis of the synergistic physiological parameters to the end of the training session the students have decreased the value of integrative indicators. In the 7-dimensional parallelepiped phase space (Vx), limiting quasi-attractor VSOCH decreased by 81,84% (background - 656505907, after - 119219144), the overall asymmetry (Rx) - at 26,75% (background - 6.3027, after - 4.6167). In the 10-dimensional parallelepiped Vx decreased by 59,01% (background - 8.49144195 * 1010, after - 3.48373001 * 1010), Rx - to 59,67% (background - 92.7907, after - 37.4184).

Intensive short-term activation of proprioceptive students during academic classes reduces the phase space quasi-attractors VSOCH motion and asymmetry coefficients (the distance between the geometric center and stochastic quasi-attractor). This indicates that an increasingly smaller proportion of the synergies and the chaos of the functional state of the students at the end of the academic session, which is characteristic of stress reduction.
