@fitters everywhere are moving out of their parents' basements and into tree forts in their parents' backyards.

Richard Branson has a zipline out of the upper story bathroom of his island home. The Gorilla can respect that.

Repetitive Overhead Activities

Repetitive overhead activity, such as throwing a baseball and other overhead sports, is another common mechanism of injury frequently responsible for producing SLAP injuries. This is the type of SLAP lesion that we most often see in our athletes. In 1985, Dr. Andrews first hypothesized that SLAP pathology in overhead throwing athletes was the result of the high eccentric activity of the biceps brachii during the arm deceleration and follow-through phases of the overhead throw. To determine this, they applied electrical stimulation to the biceps during arthroscopic evaluation and noted that the biceps contraction raised the labrum off of the glenoid rim.

Burkhart and Morgan have hypothesized a “peel back” mechanism that produces SLAP lesion in the overhead athlete. They suggest that when the shoulder is placed in a position of abduction and maximal external rotation, the rotation produces a twist at the base of the biceps, transmitting torsional force to the anchor.

This mechanism has received a lot of attention and several studies seem to show its accuracy. Pradham measured superior labral strain in a cadaveric model during each phase of the throwing motion. They noted that increased superior labral strain occurred during the late-cocking phase of throwing. A recent study from ASMI simulated each of these mechanisms using cadaveric models. Nine pairs of cadaveric shoulders were loaded to biceps anchor complex failure in either a position of simulated in-line loading (similar to the deceleration phase of throwing) or simulated peel back mechanism (similar to the cocking phase of overhead throwing). Results showed that 7 of 8 of the in-line loading group failed in the midsubstance of the biceps tendon with 1 of 8 fracturing at the supraglenoid tubercle. However, all 8 of the simulated peel back group failures resulted in a type II SLAP lesion. The ultimate strength of the biceps anchor was significantly different when the 2 loading techniques were compared. The biceps anchor demonstrated significantly higher ultimate strength with the in-line loading (508 N) as opposed to the ultimate strength seen during the peel back loading mechanism (202 N). You can see photos of the study below. The first photo is a normal glenoid with the labrum and attaching long head of the biceps. The second photo is the simulation of the traction and eccentric biceps contraction. The final photo is simulation of the peel-back lesion.

In theory, SLAP lesions most likely occur in overhead athletes from a combination of these 2 previously described forces. The eccentric biceps activity during deceleration may serve to weaken the biceps-labrum complex, while the torsional peel back force may result in the posterosuperior detachment of the labral anchor.

Avoiding the kipping pull-up does for arboreal locomotion what avoiding the squat does for bipedal locomotion - renders you physically impotent.

Couldn't have happened to two more deserving cunts.

Most arboreal creatures don't weigh very much.

They combine a low bodyweight with high strength to weight ratio.

Attempting to brachiate without a great S:BW puts you at risk from ground dwelling predators.
