Abstract

The javelin throw is a track and field event,
which is of very great antiquity. The most important goal in the javelin throw
is the throwing record. In the javelin throw, three factors (initial velocity



















, initial throw angle

 and initial throw
height H) play a fundamental role in an athlete's record. Throwing record only
depends on these three factors, but of course each of them alone is subject to
various factors at the time of throwing: the place, time, environmental and
physical conditions of an athlete. In this study, these factors were expressed,
analyzed and investigated, and the physical, technical and computational
parameters with greater precision (from the perspective of sports engineering)
were also expressed, and thus the optimum modes for each of them were obtained.
The initial throw velocity (V₁),
initial throw angle (θ₁),
initial throw height (H), their roles in throwing record and the technical
parameters affecting them have been investigated. Results show that the equations of optimum modes were obtained
for the three aforementioned variables. Depending on a series of specific
initial values for each athlete, an optimum mode of initial velocity, initial
angle and initial height of throw were obtained for each athlete, resulting in
the maximum record for throwing.
