This paper reports a study of the optimal release of men's and women's new and old rule javelins involving modeling, simulation, optimization (including sensitivity analysis), and simulation evaluation. Because of the lack of repro-ducibility in earlier results of two-dimensional flight simulation research, the paper presents a continuation of the two-dimensional model used previously. As expected, each javelin was found to have a different optimal release for a given individual, and the… 
Discovering Optimal Release Conditions for the Javelin World Record Holders by Using Computer Simulation
The purpose of this study is to use computer simulation to establish the optimal release conditions for javelin world record holders. The researcher adopted the data on the relationship between the
SIMULATION OF THE FLIGHT DISTANCES OF JAVELINS BASED ON A NEURAL NETWORK APPROACH
INTRODUCTION: The flight distances of javelins are determined by the release parameters as well as by the forces acting on the javelin during flight. The flight phase of the javelin has been under
Neural network based models of javelin flight: prediction of flight distances and optimal release parameters
A model has been developed to predict the flight of javelins using a multi-layer-perceptron neural network. The input parameters to the model are three release angles and the velocity at release,
OPTIMIZATION OF FLIGHT DISTANCE FOR THREE TYPES OF JAVELIN TIP
Optimization of javelin flight distance was carried out using a genetic algorithm. Javelin tips with three different shapes were designed within the confines of the regulations. The first design was
Optimising the javelin throw in the presence of prevailing winds
Javelin flight is strictly governed by the laws of aerodynamics but there remain well-entrenched but misleading views about the factors involved. This paper gives a simplified but fundamentally
Biomechanical Factors Critical for Performance in the Men’s Javelin Throw
TLDR
It would appear that a thrower’s body position at the instant of final foot strike, his ability to transfer momentum between the lower body and the upper body during the delivery, and coordination of the working body segments in the most effective manner are linked to his success in the event.
Release parameters at the foul line and the official result in javelin throwing.
TLDR
Release speed was found to have the highest correlation with the official throwing result, and the three release parameters accounted for 56% of the variance in the official result for the male and 51% for the female throwers.
Damping of Javelin Vibrations in Flight
Javelin vibrations in flight are caused by large forces applied transversely to the javelin's long axis during its acceleration. These decay throughout the early portion of the flight but can have
TECHNIQUE ASSESSMENT OF THE JAVELIN RELEASE PERFORMED BY YOUNG SERBIAN ATHLETES
The purpose of the present study was to indicate the biomechanical parameters of the delivery phase associated with performance in young javelin throwers. Seven right-handed young Serbian club level

Optimum Release Conditions for the New Rules Javelin
Changes in the rules for construction of the men's javelin have dramatically altered the pitching moment profile as a function of angle of attack. Thus the optimal release conditions are different

TLDR
This paper presents, categorize and discusses the relative significance of various initial conditions in such a simulation of javelin flight, and investigates the effects of some design and environmental parameters on optimal initial conditions and trajectories.
The biomechanics of javelin throwing: a review.
TLDR
The scientific literature and that on the sports sciences relevant to javelin throwing is critically reviewed and some prognoses as to the direction of future research into this complex throwing skill are offered.
Rapid and accurate estimation of release conditions in the javelin throw.
TLDR
A system to measure initial conditions in the javelin throw rapidly enough to be used by the thrower for feedback in performance improvement and provides the ability to critique nearly instantly in a precise, quantitative manner the crucial factors in the throw which determine the range.
A three-dimensional analysis of javelin throwing technique.
TLDR
Three-dimensional analysis of the best throws from the women's and men's javelin competitions at the 1991 World Student Games in Sheffield indicated the possibility of two different throwing techniques, within and between individuals, relating both to the timing of hip joint actions within the kinematic chain and the trade-off between the impulse applied to the Javelin and run-up speed.
Simulation of javelin flight using experimental aerodynamic data.
TLDR
It is shown that the use of experimental aerodynamic forces and Moments in the equations is preferable to theoretical approximations for these forces and moments which have been used in previous studies.
