Spin versus Glide
The spin technique was first practiced in Europe in the 1950’s but did not receive much attention until the 1970’s. In 1975, Brian Oldfield threw a world best 75’0” and Aleksandr Baryshnikov of the Soviet Union won the bronze medal in the Montreal Olympic Games in 1976.
The positives and negatives of each technique
The glide seems better suited for tall, largely built athletes. The glide has more consistent results and is easier to execute. On the negative side, the glide has a limited force application and speed development across the ring. For example, a good technical glider thrower may add 10% from the standing throw to the glide where as a good technical spinner by add over 20% from a stand to the full throw.
Athletes of all sizes and strength levels can use the spin. The greater and longer application of force and momentum produces further throws in the spin. The ball is constantly moving in the spin technique, setting up a more explosive finish. However, the rhythm of spin technique is a difficult to master especially for athletes with limited practice schedules. Also, the path of the shot is not as linear as the glide causing inconsistent release patterns.
