According cadaveric, neurosurgical and medico diagnostic evidence the Axillary Arch of Langer (AA) creates Symptoms similar to those of entrapment or obstruction type syndromes. In addition to the existing anatomical evidence and based on similar functional reasoning one can assume that in swimming the AA influences the shoulder girdle kinesiology also. In order to complete our knowledge of the AA we evaluated strength, endurance, motor control, precision and proprioception in two groups of physical education students (all good and average swimmers) one with AA and a control group without AA (both N=22). The results indicate a significant (p<0.05) influence of the presence of an AA on strength, throw or pull/push endurance and motor control increase in women associated with a minor increase of parasthaetics. For all these parameters no significant difference occurred in men. The pull/push Simulation and proprioceptive joint position sense data however indicate a decrease both in men and women (p<0.05).These finding do not fully confirm the anatomical predictions from the cadaveric evidence nor support the diagnoses of excision of the AA.
