The last sentence is noteworthy in it's absolute nonsense and makes my quoted post even more relevant.No, people study this stuff.
Common upper extremity injuries in resistance training athletes include muscle strains, ligament sprains, pectoralis major tendon ruptures, distal biceps tendon ruptures, and chronic shoulder pain and capsulolabral injuries. While each injury is unique ...www.ncbi.nlm.nih.gov
Chronic injuries to the capsulolabral complex of the shoulder can plague any overhead athlete, including weightlifters. Researchers have found that 36% of injuries in the weightlifting population occur at the shoulder complex.8, 26
Most authors agree that chronic repetitive loading of the shoulder complex leads to capsular strain, occult instability, and persistent pain. Upper extremity resistance training exercises place emphasis on large muscle groups to create strength and hypertrophy while neglecting smaller muscles responsible for upper extremity joint stabilization. Specifically, exercises that emphasize larger muscle groups may create an imbalance of the internal versus external rotator cuff musculature, rotator cuff-deltoid force couple, and periscapular musculature. These imbalances have been associated with shoulder injury in various investigations.27, 28, 29 The combination of repetitive loading, unfavorable positioning, and biased exercise selection creates joint and muscle imbalances that increase the strength trainer’s risk of labral tears, labro-capsular junction dysfunction, and shoulder instability, which can precipitate RTC disease.8, 30, 31
Given the propensity for shoulder dysfunction in weightlifters, it is paramount that participants understand the risks that certain exercises pose and the modifications that can be made to prevent injury. While chronic shoulder problems are a common affliction of weightlifters, the mainstay of treatment is modification of the training regimen and conservative treatment with symptomatic management and guided physical therapy. Avoidance of high-risk exercises and strengthening of shoulder stabilizers obviates the need for surgical intervention in the vast majority of cases.
Bench pressers may be predisposed to rotator cuff tears because of the unfavorable position of the rotator cuff during lifting and the pursuit of higher one-repetition maximum lifts. Furthermore, there is a rapid alternation between eccentric and concentric muscle contraction with this motion.32 One study stated that during maximal bench press, repetitive forces lead to eventual avulsion of the posterior scapular periosteum which may necessitate posterior labral repair to resume pain-free weightlifting.33 Bilateral anterior glenohumeral dislocations have been reported as a result of bench-pressing.34, 35
As with everything physical; how do you mitigate injury risk? With managed control. Specific to what we do, we strictly manage form and load in both volume and resistance. Little things like retracting the scapula to relieve tension in the shoulder is something 99+% of people bench pressing will never consider....we do.
Everything in life carries risk. To try and completely dismiss anything with associated risk will not even allow you to do nothing. Bench pressing carries lower risk to the shoulder joint than surfing/swimming, baseball, basketball, football, wrestling/grappling and so on and so on.I't strange that you are fixated on this.
