It is shown directions of biomechanics substantiation of implementation acrobatic rock-and-roll Fus-salto element taking into account concrete physical data of sportsmen. Mathematical model is developed for determination the influence on a quality of implementation of technical element of such parameters as: speed and angle of flight of centre-of-mass sportsman’s body, position of centre-of-mass body of sportsman in the initial phases of throw exercises, initial angular velocity of rotation of body of sportsman. It is developed mathematical model to determine the impact on the quality of the technical element parameters such as speed and angle of flight of centre-of-mass of the athlete's body, the position of center-of-mass of the athlete's body in the initial phases of throwing exercises in the initial angular velocity of the athlete's body. The parameters of exposure axial moments of inertia for different groupings of body angular velocity the athlete's body in flight and air resistance forces of environment to flight characteristics of the body. Directions of choice of necessary biomechanics descriptions which are able to realize sportsmen are shown. It is offered recommendations are on the increase of efficiency of implementation of element of acrobatic rock-and-roll of Fus-salto.

Several researchers have argued that the Current Population Survey (CPS) undercounts the number of individuals on public insurance and as a result overstates the number of individuals who are uninsured. This paper compares survey estimates from the CPS to estimates from the Medical Expenditures Panel (MEPS). The CPS estimates for both the size of the Medicaid and uninsured populations are above the full-year MEPS estimate but below the at-least-part-year MEPS estimate. The CPS does not appear to overstate the number of uninsured because CPS uninsured estimates are only slightly higher than MEPS full-year uninsured estimates and MEPS data clearly demonstrate that many people are uninsured for only part of the year.
