Our upper bodies are the engine rooms that power every throw, swing, pull, and press. Yet the very muscles that generate that power pectorals, rotators, biceps, lats, triceps, and deltoids are the most frequently injured in both elite sport and everyday physical work. Recent studies show that upper‑limb muscle injuries account for roughly 60 % of all non‑contact injuries in professional team sports.
Pectoralis Major (Chest) Strain / Rupture
What is the main cause - During concentric bench press or fly motions, the muscle shortens under heavy load; a sudden overload can cause partial or full‑thickness fibre rupture.
Rotator Cuff (Supraspinatus) Strain / Partial‑Thickness Tear
What is the main cause - Repetitive overhead abduction creates impingement and compressive shear at the tendon‑bone interface. Micro‑trauma leads to collagen disarray, neovascularisation and eventual partial‑thickness tearing.
Biceps Brachii (Long‑Head) Strain / Tendon Rupture
What is the main cause -Sudden eccentric loading (e.g., lowering a heavy dumbbell) can cause a partial or full‑thickness tear of the muscle belly or a rupture of the distal tendon.
Latissimus Dorsi (LD) Strain / Avulsion
What is the main cause - Overhead pulling or forceful trunk extension (pull‑ups, rowing) can cause a muscle‑strain or, in extreme cases, an avulsion of the tendon from the humeral insertion.
Triceps Brachii (Long‑Head) Strain / Tendonitis
What is the main cause - Repetitive overhead extension (swimming, triceps dips) produces micro‑tears and tendinopathic degeneration. Acute strains manifest as partial‑thickness tears at the musculotendinous junction.
