Steve Cotter Fluid Style vs. Hard Style video analysis

A video analysis about Steve Cotter making a demonstration about the differences in kettlebell lifting styles. (Original video published in CrossFit Journal. Analysis done with Tracker software.)

Based on this video analysis:
1. Hard style swing requires slightly more force (780 N) than the fluid style swing (750 N)
2. Hard style swing consumes more energy per rep (390 J vs. 280 J)
3. The power output during a HS swing is twice the power output during a FS swing (660 W vs. 315 W)

So what's your conclusion? Hard style or fluid style..?

[TumppiWw]

@FabiusPyromanus Hardstyle for burning energy in an inefficient manner and working the glutes = fitness. Fluid style for promoting efficient movement patterns and helping Girevoy Sport training.

Your math seems to be off.

[TumppiWw]

@Maxdwolf Good! The energy/work demand was calculated as the difference between minimum and maximum of total energy (kinetic + potential) throughout the move. Work was calculated as this difference divided by time. Do you have a suggestion for doing this better? If so, thanks!

what program/ website are you using for analysis?

[TumppiWw]

Tracker, as mentioned in the video description.

Google: tracker video analysis and its probably the first hit

Look, I'm a competing GS-amateur. For me the swing is not an exercise, it is training for the snatch, which is done in the rep range of >100. Then, ergonomics do count.

Otherwise I agree completely. For fitness, just grap a relatively light bell and start swinging, juggling and playing around. You'll feel the difference! :)
