Also, Olympic lifters traditionally have some of the highest vertical leaps recorded and they do mostly explosive movements. It would seem that Luke has an opinion that is not supported by much of the industry when he says that cleans are actually sending the body a signal to go slower to something like that. Everything I have read about explosive movements says that they help the body recruit more motor units and increase rate coding.
Some science actually says something different. For example:
EXPLOSIVE EXERCISES IN SPORTS TRAINING: A CRITICAL REVIEW
This paper reviews evidence relating to the effectiveness and safety of explosive exercises, such as Olympic style weight lifting, other weight training exercises performed at a fast cadence, and plyometric exercises, that are commonly used in the strength and conditioning training of athletes. Contrary to popular belief and the practices of many athletes, the peer-reviewed evidence does not support the view that such exercises are more effective than traditional, slow and heavy weight training in enhancing muscle power and athletic performance.
In fact, such exercises do not appear to be any more effective in this regard than weight training at a relatively slow cadence, and some evidence suggests they are less so.
Also, such explosive exercises do not transfer well (if at all) to athletic performance on the sports field, and present a significant injury risk. Therefore, such exercises should not be recommended in the strength and conditioning training of athletes, except those who need to learn the specific skill of lifting heavy weights fast, such as Olympic lifters and strongmen.
The whole paper is there for download.
See what it says:
- explosive moves are no better than standard slow repetitions
- they might actually be worse
- they present an injury risk
- the do not transfer over to the skill anyway.
There are other similar studies. For example this guy's thesis or this outstanding analysis and review of the literature:
After an extenive survey of the relevant studies the paper concludes:
In summary, there is very little evidence cited in the Position Stand to support the claim that explosive, multiple-set protocols are required to enhance the ability to produce power (Table 10), or enhance specific sport skills or functional ability.
