Progress And Prediction Of World Record Performances In Jump And Throw Athletic Events

Introduction
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 talents4,5, 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).
Purpose
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.

Methods
Math. models: a) y=a+blnx/x2 b) y=a+b x2 +c x2Öx+dx3
c) y=a+bln x2 +clnx · World record performances in track and field events for men3.
· Athletic event: Jumps: long jump, triple jump, high jump, pole vault.
Throws: shot putt, disc throw, javelin throw, hammer throw.
· Prediction of world record performances2,3. · Data elaboration program: Math software TBL CURVE version 5

Results
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.

Conclusions
The results of this study are just a prediction according to the criterions of the evolution and the progress of the world
performances, giving useful information to athletes and trainers.
