Upper Body Injuries Flashcards
(15 cards)
What causes rotator cuff tears in overhead lifters?
Excessive shoulder loading, poor scapular control, and decreased muscle flexibility.
What injury is common in fatigued CrossFit athletes?
Shoulder impingement due to internal rotation and altered joint angles during repetitive movement.
What’s the importance of progressive loading for muscle-ups?
To prevent exceeding shoulder tissue tolerance in untrained individuals.
What is the most common shoulder injury in overhead lifters?
Subacromial impingement syndrome.
Which rotator cuff muscle is most commonly involved in lifting injuries?
Supraspinatus
What is a common symptom of rotator cuff tendinopathy?
Pain during overhead activity and weakness in abduction/external rotation.
What shoulder joint is often affected by barbell pressing without adequate recovery?
Acromioclavicular (AC) joint.
What position typically causes traumatic shoulder dislocation?
Abduction with external rotation.
What scapular muscle imbalance commonly contributes to impingement?
Upper trapezius overactivation leading to scapular elevation.
What upper body structure provides the base for glenohumeral motion?
The scapula.
Describe how fatigue can increase shoulder injury risk in CrossFit athletes.
Fatigue leads to increased internal rotation, reduced scapular control, and altered neuromuscular timing, elevating the risk of strain and impingement.
Explain the mechanical cause of rotator cuff tears in overhead strength athletes.
Repetitive eccentric overload during external rotation, especially when lowering weights under fatigue or with poor technique.
How does scapular dyskinesis increase injury risk during pressing movements?
It alters scapulohumeral rhythm, placing excess stress on the rotator cuff and reducing subacromial space, increasing impingement potential.
Describe how posterior shoulder instability develops in power athletes.
Through repetitive horizontal adduction and internal rotation (e.g. bench pressing) without proper posterior capsule strength or stability.
What postural and movement deficits contribute to subacromial impingement in lifters?
Excessive scapular elevation, thoracic kyphosis, poor external rotation, and internal rotation dominance under fatigue.
