Query: Diving Body Shape Coefficient Setting Based on Moment of Inertia
  Analysis   In the diving competition rules, FINA specifies the code of different diving
movements and its difficulty coefficient. The rule simply relies on the
complexity of the action to determine the difficulty. In the formulation of the
diving difficulty coefficient, the athlete's body shape has not been fully
considered, so it is difficult to fully guarantee the fairness of the diving
competition. Based on the above problems, this paper analyzes the rules of the
FINA's 10-meter platform diving difficulty coefficient, establishes the
multi-rigid-body model of the human body, obtains the relationship between the
moment of inertia and the completion time of the athletes to complete each
diving action and the athlete's body shape, and determines the index to measure
the athlete's body shape. The Lagrange Interpolation Polynomial is used to
establish the functional relationship between the body shape correction
coefficient and the body shape correction index, and the body shape correction
coefficient corresponding to different body type athletes is determined
accordingly. Finally, a new 10-meter platform diving difficulty coefficient
scheme was developed.
