Progress and prediction of World record performances in jump and throw athletic events
The rate of progress of record performances, especially in track and field events which determine the human abilities limits, constitutes a research challenge for all scientists. Because of the fact that record performances are continuously improving, many people have the impression that there is no limit in them. There is no doubt, that the improvement of world record performances is due to the methods of training, the systematic choice of athletic talents the progress of the medical and pharmaceutics sciences, the improvement of the techniques in the sports themselves (High Jump and Shot Putt (Graph.1) and the adoption of new materials (Pole Vault (Graph. 2), Javelin Throw, elastic carpet).
So, for this reason, the present study deals with the predictions and the progress of the world record performances in the athletic events of jumps and throws, with the assistance of math models1.
Math. models: a) y=a+blnx/x2 b) y=a+b x2 +c x2 x+dx3
c) y=a+bln x2 +clnx " World record performances in track and field events for men.
" Athletic event: Jumps: long jump, triple jump, high jump, pole vault. Throws: shot putt, disc throw, javelin throw, hammer throw.
" Prediction of world record performances" Data elaboration program: Math software TBL CURVE version 5
Prediction of world record performances in the athletic events of jumps and throws that are concluded by math equations going along with the progressive evolution of the world record. The Disc Throw had margins for improvement. The change of the place of the center of gravity in javelin declined the record performances and deformed the application of the model. According to the above mentioned equation the disc thrower who aims to break the world record performance at the Olympic games in Athens in 2004 must throw more than 77 m. (factor of definition (R2)=96, St. error 1.72 m.). Having such aims an athlete of long jump has to jump 8.96 m. (R2)=87, St. error 12 cm), while a triple jump athlete will achieve world record performance if he jumps 18.46 m. (R2)=89, St. error 24 cm. Table 1). The above mentioned results constitute just a prediction according to the criteria of the evolution and progress of the record performances.
