Angle Of
Releases Of The Equipment
The Next
Important Factor Is The Angle Of Release Of The Equipment. In Throwing
Events,
The Optimum Release Angle Differs From Event To Event.
When A
Piece Of Equipment Is Released In The Proper Angle, It Can Be Thrown Further
And When
That Equipment Is Thrown At Angles Greater Or Lesser In Magnitude To The
Proper
Angle, The Equipment Lands At Shorter Distances.

Height Of
Release Of The Equipment
In A
Throwing Event, The Height Of Release Of The Equipment Is A Factor That Depends
On The
Height Of The Athlete. An Athlete Who Is Taller Than Another Can Release The
Equipment
At A Greater Height When Compared To The Shorter One. If All The Other
Factors
Are Equal, The Athlete Who Releases The Equipment At A Greater Height Is In A
Slightly
Advantageous Position. (Figure 3.13)
