Only lifts in the 70-80 % range have meaningful value for them. They use it every training.

TL;DR

• mobile work station that uses the Microsoft Kinect camera system
• they collect 3d data, and build a database for each lifter
• used in training and competitions
• it gives real time measurement, instant feedback

Video

Here is a quick video showing it in use.

Things it Measures

• bar path
• bar height (in meters, % of body height)
• bar velocity
• bar acceleration
• horizontal bar displacement
• minimum height required to make the lift
• all values are real-time and synchronized with the video
• comparison of lifts

Key Moments

For Snatch and Clean

• Bar max. acceleration
• Bar max. velocity
• Bar max. height
• Bar fixation

For Jerk

• Dip depth
• Bar max. velocity
• Bar max. height
• Bar fixation

Update: Reader Max Boone shared this video of him having his lift analysed by the machine.

#tbt to six months into my weightlifting career. I am at Beijing Sports university in 2014 for the @mastrength Camp. I got to meet the inventor of the Chinese weightlifting instant (real time) assessment system. My snatch has improved dramatically since then #weightlifting #olympic #lifting #snatch #chineseweightlifting #analysis #analytics #smart #lifting @jianpingma @mastrength @atginsta @awesome_weightlifting @usa_weightlifting @lu_weightlifting
