Many exercise movements are recommended to be performed slowly, deliberately, and under control. Slow and controlled movements help to mitigate the risk of sudden and excessive stress and twists which may lead to injury.
Explosive movements (swings, cleans, jerks, etc.) by definition do not allow for slow execution, and they seem to lessen the potential for controlled performance. This would seem to increase the risk of injury from these movements.
However, one may imagine that there are those who perform these movements regularly and over long periods of their workout careers and for whom the cumulative stress produced by these movements results in no significant adverse effects.
Do explosive movements necessarily lead to serious injury over the long term?
If not, how do muscles and joints achieve the ability to absorb the amounts of force that these movements produce, and how does this differ from exercises which are best performed slowly?
Are any of the assumptions in the above paragraphs incorrect?
