2. The Snatch
(5)
• Variations used for power training in athletes
• Popular exercise to develop power through the
hips and knees
• Very technical, needs to be taught well before
execution
3. How to snatch
• Step by step guide from Andrew Tysz (4), head
weightlifting coach at the US Olympic Education
Center Northern Michigan University
• 6 phases
Start
1st pull
2nd pull
Drop
Receiving
Squat
5. Literature 1
• A biomechanical review by German coach Klaus
E. Bartonletz, PhD(1).
• Titled “Biomechanics of the snatch: Towards a
higher training efficiency”
• Designed to give coaches an understanding of
the biomechanical processes and training
approaches to increase efficiency
6. The Study
• Believed not to be and original idea for a
publication
• Shows importance in highlighting aspects of the
lift the coach should know of and ideas to teach
• Literature not a typical study with
participants, rather a collaboration of previously
found info
• Written as the equivalent of a background and
discussion
7. Limitations
• Technique will differ due to limb length
Eg taller athletes will have smaller knee angles due
to the lower crouch
• Heavy weight athletes will need greater velocity
to the smaller classes
(8)
9. Coaching help
• Determine movement path of bar by videotape
• find target bar velocity for max lift
• Calculate power at max velocity, will help to
conserve same energy for lighter weight training
• Snatch variety needs to have common grounds
with sporting movement
• 5-10% yearly power increase is an attainable goal
10. Conclusion for Coaches
• Continue with alternate max strength exercises
• Young athletes to work on overall
strength, progression into advanced movements
• Split leg lift for specific athletes
Baseball pitchers
Contact sports
• Squat snatch for high leg load sports
Rowing
Skiing
11. Literature 2
• Study by Schilling et.al titled “Snatch Technique
of Collegiate National Level Weightlifters” in
2002 (3)
“bar trajectory during weight lifting movements
is related to the position of the body during the
lift and the displacement of the feet during the
drop-under phase”
12. Research
• 25 male colligate athletes from 7 different weight
classes
• Camera placed on saggital plane
• Toes manually digitized at the end of 2nd pull
• 74 total lifts recorded, comparison between
regular and maximal lift
• Both foot displacement and bar trajectory were
recorded
13. Findings
• Type B trajectory of bar will
result in rearward foot
displacement
• Lighter lifters would stay
grounded for longer and use (3)
their body as a counterweight
• Not enough evidence to show a connection
14. Further Research
• 3D analysis for transverse plan
• Use elite performers instead of amateur
• Force plate, electromyography and ultrasound
for immediate feedback
• Incorrect technique for comparison
(9)
15. Coaching Uses
• Foot and bar displacement are closely related
• Rearward displacement used by elite lifters
• When coaching snatch, emphasize the foot
placements to make it become second nature
16. Summary of Coaching Implications
• Feet slightly turned out in starting position
• Body type will effect technique
• Body weight is related to velocity needs
• Hips to produce greatest power output
• Young athletes to progress into full snatch after
strength work
• Rear foot displacement believed to be optimal
technique
• Barbell should stay behind vertical line
