Significant differences between the CE and CT groups were seen in Delta 1RM squat (65.8 and 27.5 kg, respectively) and Delta 1RM power clean (25.9 and 3.8 kg, respectively). No other between-group differences were observed. Results of this study provide evidence of the benefits of the jump squat exercise during a short-duration (5-week) training program for eliciting strength and power gains. In addition, the eccentric phase of this ballistic movement appears to have important implications for eliciting these strength gains in college football players during an off-season training program. Thus, coaches incorporating jump squats (using both concentric and eccentric phases of contraction) in the off-season training programs of their athletes can see significant performance improvements during a relatively short duration of training.

I had posted that one the other day after I saw it on Dos Remedios's blog (http://coachdos.blogspot.com/).

I've been doing PCs followed by jump shrugs as I tire and don't trust myself on keeping form. I can continue to increase the weight that way to probably 30+ lbs more than I can PC, so it gets me used to a bigger weight with my grip and also I think teaches me the mechanics a bit.
