Abstract.

Comfort, P, Allen, M, and Graham-Smith, P. Comparisons of peak ground reaction force and rate of force development during variations of the power clean. J Strength Cond Res 24(x): 000-000, 2010-The aim of this investigation was to determine the differences in vertical ground reaction forces and rate of force development (RFD) during variations of the power clean. Elite rugby league players (n = 11; age 21 +/- 1.63 years; height 181.56 +/- 2.61 cm; body mass 93.65 +/- 6.84 kg) performed 1 set of 3 repetitions of the power clean, hang-power clean, midthigh power clean, or midthigh clean pull, using 60% of 1-repetition maximum power clean, in a randomized order, while standing on a force platform. Differences in peak vertical ground reaction forces (Fz) and instantaneous RFD between lifts were analyzed via 1-way analysis of variance and Bonferroni post hoc analysis. Statistical analysis revealed a significantly (p < 0.001) greater peak Fz during the midthigh power clean (2,801.7 +/- 195.4 N) and the midthigh clean pull (2,880.2 +/- 236.2 N) compared to both the power clean (2,306.24 +/- 240.47 N) and the hang-power clean (2,442.9 +/- 293.2 N). The midthigh power clean (14,655.8 +/- 4,535.1 N[middle dot]s-1) and the midthigh clean pull (15,320.6 +/- 3,533.3 N[middle dot]s-1) also demonstrated significantly (p < 0.001) greater instantaneous RFD when compared to both the power clean (8,839.7 +/- 2,940.4 N[middle dot]s-1) and the hang-power clean (9,768.9 +/- 4,012.4 N[middle dot]s-1). From the findings of this study, when training to maximize peak Fz and RFD the midthigh power clean and midthigh clean pull appear to be the most advantageous variations of the power clean to perform.

Crossfitter at my gym just popped his achilles. That is some ugly shit.

How did he do that?.

Its highly likely that all the athletes in that vid juices. But as long as it has not been proved Id rather be ignorant and enjoy it.  

It's all speculation though. That usually comes from the haters.

Just pulled up a couple of vids.

What are the best way to perform these?. Partial from hang or full ROM?.

Westside Owns the Powerlifting World Yet Again!!!

This last weekend two Westside lifters, AJ Roberts and David "Neutron" Hoff both destroyed the all-time world records in their respective weight classes!

AJ hit a 2,825 lbs total with a 1,140 squat, 870 bench, and 815 deadlift. He competed as a 308. His was the highest all-time total for a 308 and the 2nd highest all-time total period!

David hit 2,805 with a 1,115 squat, 880 bench, and 810 deadlift for the all-time best 275 class total!

Congratulations to both men and to Louie Simmons, the architect of the Westside system of training and the greatest strength training coach ever.

The planche Push-up is something special.

Thanks for all this adarqui.

Appreciate it.
