It is about strength that you can use or apply on the field, court or track. There is an over emphasis on the force production aspect of strength training as indicated by how much weight we can lift or foot ponds of force we can express on a dynamometer. Conversely there is an under appreciation and lack of emphasis on the force reduction component, which is the ability to stop or decelerate, partially because is it is not as easy to measure.
Muscles work together to produce integrated and coordinated patterns of movement.
The key word is control.
