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.
TLDR
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.
TLDR
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.

TLDR
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.

A force-velocity relationship and coordination patterns in overarm throwing.
TLDR
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.
