Researchers from China’s Ningbo College have identified what makes the crucial distinction among an elite snatch model weightlifter and a sub-elite one, according to a new research published in the journal Heliyon. In the Olympic activity of snatch design and style weightlifting, athletes squat, consider keep of a barbell on the floor, and then raise it with outstretched arms overhead, working with one ongoing motion. Conclusions exhibit that the good results of this maneuver comes down to the power of a component of the entire body that may possibly not seem to be quickly apparent: the knees.
“These results can present worthwhile info for lower degree lifters and coaches to attain greater levels of competition efficiency by altering their coaching procedures appropriately,” said the study’s corresponding writer Yaodong Gu, PhD.
To obtain out their solution in the new examine, Dr. Gu and colleagues, like to start with writer Gongju Liu, analyzed video clip info gathered all through the 2015 Men’s Chinese Countrywide Championship and the 2016 Men’s Chinese Olympic trials applying a innovative motion investigation procedure. China has had a lengthy historical past of accomplishment in the sport, with gold medals in the 69kg course in the earlier 4 Olympic Game titles. The leading six weightlifters analyzed have been thought of leading-elite athletes. Athletes rated in 2nd to 7th put at the Chinese Championships, a second-tier function in China, have been considered sub-elite. The dilemma was: what’s the variation among them?
The scientists report the significant distinctions have been in the greatest vertical height of the barbell, as effectively as its top relative to the person lifter’s height. There have been also discrepancies in the vertical linear velocity of the barbell, and in its vertical acceleration. For sub-elite lifters to reach elite standing, all those are the parts to get the job done on.
“Coaches of sub-elite lifters should really concentrate on exercise routines suitable to the power qualities of the initial and 3rd phases of snatch carry,” Dr. Gu stated. He also highlights that the major conclusions of the existing study have now been applied to the instruction assistance of China’s snatch type athletes, a single of whom received the gold medal in the 2016 Rio Summer season Olympic Game titles and the Gold Medal in the 2015 Environment Championships.
There was a little something else, even so: Sub-elite lifters showed substantially slower angular velocity of the knee joint in the second section of the lift compared with top-elite lifters.
The added findings propose that sub-elite lifters should really operate on strengthening the flexor muscles of their knee joints, earning it probable for them to crank out and use extra elastic electricity in the next section of a carry.
Dr. Gu and his study group are now discovering the snatch procedure of three Olympic Champions, and system to carry out additional scientific tests of the snatch system of leading-elite weightlifters as they lift even heavier weights.
