My conclusions thus far are open to change – if I find compelling enough evidence to warrant a change. So far I have found lots of research saying sports specific moves make no difference and lots of opinions saying it does. Opinions are warranted and can be good causes for further research – however, thats all they are, no matter how many people hold that opinion.
I ubderstand the training effect a drop jump has, the question that arises is;
does it improve your vertical jump more than jumping training and strength work?
if it doesnt make any difference over or compared to traditional low impact/force squats etc then is the potential for future injury worth risking for something that is no more effective than a safer alternative?
Western style periodisation – what makes you think I was headed that way? Not a great fan of periodisation past a simple back off and take a rest.
Drop Jump training will have almost no impact on Vertical Jump training. I stated this would be the case. Notice in the study below how the CMJ group improved in Squat Jump and CMJ, but not depth jump, but the depth jump group improved in all 3. The purpose of the drop jump is not to improve CMJ, but the DJ is more specific to sport related movements.
Here is something you can reference though and why you should train power and not strength! No one here will deny that specificity in movement patterns and loads is not the most important aspect of training.
ps – learn to use quotes a little better please.
