We investigated the release angle that maximizes the distance attained in a long soccer throw-in. One male soccer player performed maximum-effort throws using release angles of between 10 and 60 degrees, and the throws were analyzed using two-dimensional videography. The player's optimum release angle was calculated by substituting mathematical expressions for the measured relationships between release speed, release height and release angle into the equations for the flight of a spherical…

Optimum projection angle for attaining maximum distance in a soccer punt kick.
The optimum projection angle that maximizes the distance of a punt kick by a soccer goalkeeper is about 45° because the projection velocity of the ball is almost the same at all projection angles.
Effect of projection variables on throw distance and flight time in an American football throw
In American football the ball is usually thrown to the receiver with near-maximum speed and a low angle so as to minimize the flight time. In this study a player performed maximum-effort throws using
Optimum projection angle for attaining maximum distance in a rugby place kick.
The optimum projection angle in a rugby place kick is about 30°, considerably less than 45° because the projection velocity that a player can produce decreases substantially as projection angle is increased.
The purpose of this study was to examine the differences in Ground Reaction Forces (GRF) between standing and running soccer throw-in. Six male amateur soccer players participated in the current

Evaluation of the relationship between isokinetic strength and two different soccer throw-in performances
The aim of the current study was to determine ball velocity and throwing distance in standing and running throw-in techniques, and to correlate this performances with isokinetic torques of the,
Throwing and jumping for maximum horizontal range
Optimum projection angles for achieving maximum horizontal range in throwing and jumping events are considerably less than 45 degrees. This unexpected result arise because an athlete can generate a
Using task dynamics to quantify the affordances of throwing for long distance and accuracy.
A task dynamical approach to the study of affordances as properties of objects and events in the context of tasks is advocated as the future of research in this area.

Optimum release angle in the shot put
The aim of the study was to assess the accuracy of a method of calculating the optimum release angle in the shot put, which was evaluated using measurements of five college shot-putters who performed maximum-effort throws over a wide range of release angles.
Mechanics of Translation and Rotation during Conventional and Handspring Soccer Throw-Ins
This study examined the mechanics of translation and rotation during the conventional and handspring soccer throw-ins. Thirteen male collegiate soccer players were filmed at 100 fps while performing
A force-velocity relationship and coordination patterns in overarm throwing.
An inverse relationship between load and velocity and a linear force-velocity exists in overarm throwing with ball weights varying from 0.2 to 0.8 kg, and no changes in coordination pattern (relative timing) occur with increasing ball weight within the tested range of ball weights.

Optimum take-off angle in the long jump
In this study, we found that the optimum take-off angle for a long jumper may be predicted by combining the equation for the range of a projectile in free flight with the measured relations between
