Using Kettlebells in the Rehabilitation of the Core Philip Johnson, MS, ATC University of Michigan
Purpose of the Presentation • Understand the history of the Kettlebell • Basic knowledge of the fundamental exercises • Uses in rehabilitation of low back injury • Case reviews • “Core” definition
What is a Kettlebell? • Best described as a “cannonball with a handle” • Styles • Fitness tool • Rehabilitative tool
History of the Kettlebell • Russian background • 18th Century Russia • Appeared in the Russian dictionary in 1704 • (Cherkikh, 1994) • Red Army • 1900’s Strongman • 1985 Soviet Union Sport
History- continued • Fitness Certifications: • Russian Kettlebell Certification (RKC) • International Kettlebell and Fitness Federation (IKFF) • Art Of Strength (AOS) • Military Training/ Fitness- SS Snatch test • 10min: snatch 24kg, 200reps • MMA/ UFC • Crazy “fitness trend”?? • Rehabilitation • Research???
Kettlebell Vs. Dumbell • Different weighted tools/ different load • KB 6-8 inches out of center of hand • Positions load anterior, posterior, moving • KB: “offset” load • Primary use to reinforce movement patterns • Focus on muscle group function in unison • Less use in isolated strengthening • Momentum driven • Convenient for explosive patterns • Grip strength
KB vs. DB • Cost $$: KB (PB/PS) DB • 8kg/ 18lb $35/36 $30/26 • 12kg/ 26lb 45/41 37/33 • 16kg/ 35lb 60/55 52/46 • 20kg/ 44lb 70/65 67/60 • 24kg/ 53lb 80/75 82/72 • 32kg/ 70lb 100/95 104/92 *reference: Perform Better(PB) and Power Systems (PS)

My Experience • **I am NOT a certified instructor** • Not well educated/ experienced in Weight Room • June 2008: Perform Better Seminar • Anthony DiLuglio • www.artofstrength.com • Enter The Kettlebell –PavelTsatsouline • Published 2006 • www.dragondoor.com
Additional Resources • Blogs/ Websites • www.begin2dig.com • www.chasingstrength.com Geoff Neupert • www.liftkettlebells.com • www.mikemahler.com • YouTube: “kettlebells” • about 22,000 videos • Google • DVD’s
Getting Started • Don’t be Intimidated! • “Average” Male 16kg, “Strong” Male 20kg • “Average” Female 8kg, “Strong” Female 12kg • “Heavy” >32 kg; traditionally 48kg is heaviest • (Tsatsouline, dragondoor.com) • Can Find: • 92kg
Benefits of Kettlebell Use • Strengthening- Muscle integration rather than Isolation • Endurance/ Cardiovascular • Power output • Grip • Efficiency of training/rehab • Reduces space needs/ Cost • Utilize a Balance of Tension and Relaxation • Hip Extension and Deceleration • Variety and Versatility
Safety Issues • Surroundings- keep clear space • Start slow- practice • Focus on movements- setting down KB • Low Back- flat back “anti-slouch” • Use Safety “Sense”
Benefits of Kettlebell Use in Rehabilitation • Postural Correction/Improvement • Reinforce Movement Patterns • Strengthen Gross Movements • CORE/HIPS! • Improve Return to Olympic Lifts • Cardiovascular Stress • (Schnettler, et al., 2010)
“Core” Specific Rehabilitation • Abdominal • Unilateral loads; Single leg stance • Functional abdominal activation • Hip • Anterior (hip flexor)- Reciprocal inhibition • Posterior (Glut/ Prox Ham)- Activation • Restore normal Lumbo-pelvic-hip function • LatissimusDorsi • Eccentric arm control • Spine stabilization • Upper/Lower Back • Segmental stabilization
The SWING • THE fundamental kettlebell exercise • Base movement for other exercises • Great posterior chain work • “dynamic” Deadlift • HIP HINGE!!!
SWING- Breakdown • Hip Hinge • Push butt back • Keep back flat • Weight on Heels • Wiggle toes • Shins vertical • Eyes ahead • Focus on spot in front • “Hike” hands • Hike football • Thumbs tight • Reach through legs with straight arms
SWING- Breakdown • Hip Drive • Extend Hips • Chest out/ back flat • Shoulder blades together • KB weightless • Be able to let go- light grip • Pendulum arms • Move passively- rope like • Momentum dependent
SWING- breakdown • Pull patella superior • Pull knee cap to ceiling • Glut tight/ squeeze • Hold a quarter in cheeks • ER hip joint • Scapula retracted • Chest out • KB to shoulder height • Not crossfit- “American” Swing • Control with latissimusdorsi
Swing- problems • Not enough weight
SWING- Problems • “Squatting the Swing”
Swing- problems • Weight Forward
Swing- problems • Hands too Low/ Rounded T-spine
Swing- problems • Low Back Hyperextension
The SWING • Quick Learning Curve • Active Core: • Gluteals • Hamstring- proximal • Upper Back • Low Back- no axial load, single plane, no rotation • Stabilization • Load away from body but controlled by hips • Latissimusdorsi • Cardio • 30s on/30s off
Rehabilitative Goals of the Swing • Back stabilization, muscular control • Posterior hip activation: • concentric glut to extend hip • eccentric to decelerate • Anterior hip- reciprocal inhibition in erect posture • Improved hip musculature coordination • “functional” abdominal contraction lower back reciprocal inhibition
Case #1- L4-L5,L5-S1 Disc • Symptoms: • Pain- limiting hip flex, knee ext • Radicular symptoms • Started KB • Decreased acute pain/ inflam • ~1week post injection • Tolerate ROM, • table (open chain) exercises • Bridge DL ROM DL wt Static carryswing • Supplement to return to weightroom
L4-L5, L5-S1 Disc Bulge • *Caution: Anterior load and Opp side load* • Farmer walk • Abdominal bracing • Overhead carry • Abdominal bracing • Sumo Squat • Core control, lumbar stability • Deadlift • Lumbar stability, hamstring flx, gluteal control • Swing • Lumbar stability, dynamic hip • Cardio?
SI Joint Dysfunction • Anterior Hip/Groin pain • Lateral Hip pain • Proximal Hamstring pain • No signs of muscle tissue damage • May have SI joint pain • Usually functional but not comfortable • Innominate rotation on exam
Case #2- SI Joint Dysfunction • Anterior Rotation of the Innominate • Sumo Squat- modify • Glut/Groin loaded- activate • Single Leg Deadlift- modify • Unilateral activation • Reinforce manual therapy correction • Goblet Squat- if ROM tolerated • Posterior rotation of pelvis • Swing • Restore normal coordination of hips
Spndylolysis • Typically pre-existing • Overweight • Lordosis • Posterior butt • Aggravated in extension • Spasm • Function but pain
Case #3- Spondylolysis- RT L3 • *Caution: Posterior and same side load* • McGill Bottom Up • Abdominal bracing • Rack Squat • Unilateral load, core control • DL- modified ROM • Lumbar stability, glut control • Swing • Lumbar stability, dynamic hips
Other Times of Use • Pre-Lift • Warm Up: 30 swings >150bpm • Poor Squat or Deadlift motion • Chronic Problems: groin/sports hernia • Off Days (10-20min) • Corrective: STM MT/Mob KB exer • Rehab (Fine Tune): ex: chronic hamstring • Cardio: 5 min tabata; circuit
Kettlebell Limitations • Always SAFETY 1st • Common sense dictates • Take time to teach movements • Learning Curve/ Progressions • Hand/Grip/Forearm injury • Hip joint pathology?
