Passive/static (non moving/non active) stretching is best done AFTER physical activity. In fact static stretching pre activity has been shown to lower power/strength output during activity.
@@adeno4444 I believe I read about it in the Journal of Strength and Conditioning Research many years ago. It has since been corroborated in multiple different studies.
@@rawmail102171 for athletic events, it is better to stretch BEFORE. The reason it's not recommend for strength and conditioning is because it makes you loose, which increases injury risk. HOWEVER being loose before starts is good
Flexible and mobile muscles are fast and loose muscles, fast and loose muscles are strong and quick, quick and strong muscles = higher velo. Hope this helps
