[Quantitative evaluation of the effectiveness of physical contermeasures against motor disorders in long-duration...

Regression analysis has been applied to determine the dependence of the motor system status (MSS) in long-duration space flight on the physical training programme (PTP), and flight duration (FD). Analyzed were graphical data presented in previous papers. Statistical analysis brought to light a high level of MSS-PTP relationship described as a 5-degree polynomial and a less explicit, yet statistically reliable MSS-FD relationship which is most adequately approximated by a 6-degree polynomial.
