Dartfish has just announced their newest version of their mobile app, Dartfish Express, now features 120 frames-per-second for those using iPhone 5s or 5c.

Snatch Technique

Thanks to John Garhammer, PhD for his clips from the 2011 World Championships, where the men's 56kg class had some tight competition.

These three lifters demonstrate very consistent technique. They have about the same starting posture. Their trajectories are quite similar, although readers will note that Tran's "hook" at the top is greater. He's also the only one to jump rearward, although it is very marginal.

Both the Chinese lifters display a complete triple extension at the top of their second pulls. Tran is close, but he does not fully extend his knees. All of the lifters fully extend their hip joints. Anyone out there paying attention to the chatter about no need for triple extension in the lifts anymore?

Check the lifts both at regular and slow motion speeds. Use the white triangles just below the Play bar to see this lifter's key positions. Advance key positions by using the Next Marker option and utilize Dartfish's Next Frame option to watch the lift frame-by-frame.
