Tendons are made of…
They transfer…
They have excellent…
collagen tissue
force from muscles to the skeletal system
tensile properties
Tendon Enthesis
Myotendinous junction
Junction between tendon and bone
connection between tendon and muscle (most prone for injury)
Tendon stress-strain curve
same as ligaments
After 4% deformation is where it gets bad
Do tendons take longer to strength train than muscles?
When does strength start to improve?, stuctural changes?
Do tendons take longer to recover than muscles?
yes, they still increase surface area (this takes 6-12 weeks of consistent training)
4-8 weeks, >12 weeks
yes, optimal loading is every 2-3 days
Enthesopathy
Treatment
physiotherapy, pain control, rest
Tendinopathy is the
mechanism
Umbrella term for tendon overuse injuries
repetitive tensile loading, sprinting or jumping, inadequate recovery
Cook–Purdam Model
Reactive tendinopathy
Worsening tendon pathology
Degenerative tendinopathy
Risk factors of tendinopathy
Intrinsic - older age, males, menopause, genetics
Extrinsic - training load, spikes in loads, periods of deconditioning
Exercise Based Rehabilitation Programs for Lower Limb Tendinopathy
Stage 1- Isometric exercises
Stage 2- isotonic and heavy slow resistance exercises
Stage 3- increase in speed and energy store exercises and single jump exercises
Stage 4- energy storage and release and sport specific exercises. Repeated jumps and direction changes
Actions of these muscles?
Supraspinatus, infraspinatus, subscapularis, teres minor
Look at painful ARC thing
Abduction, external rotation, internal rotation, external rotation
Prevention of Tendinopathy
Tendon Rupture commonly occurs in people…
____ of NFL players returned after 12 months
we can reduce risks (early treatment is important), educate people on what to do when they feel pain
aged 30-50
61% of NFL players returned after 12 months
Tendon rupture steps
eccentric force generation, mid-tendon area, partial or complete rupture
Patellar tendon partial rupture
How long till return?
Complete rupture
How long till return?
4-6 weeks
8-18 months
Management of tendinopathy
Education of patients
Load monitoring
Pain monitoring
Exercise based progressive
rehabilitation program
partial patellar rupture vs complete ruptute RTS
4-6 weeks vs 8-18 months
