DSTV / Der Schwimmtrainer 14 Juli 2014 Jessica Gal The Dutch physician, Jessica Gal, hold an interesting speech about coordination skills and their relation to injuries when it comes to swimmers. Miss Gal has experience with top athletes, talents, patients who are doing sports on a recreational level and oncological patients. Miss Gal studied medicine, is specialized in sports medicine and has her own doctors office. The main field of work focuses on traumatic cases, problems that are linked to training overload and neurological issues. First, an epidemiology of swimming injuries has been presented. Afterwards Miss Gal gave the audience an overview of the anatomy of the shoulder in general and the shoulder of swimmers to get a better understanding of the injuries and issues that often appear in swimming. A big focus was placed on the so called “swimmers shoulder” since this is the main problem swimmers are confronted with. Miss Gall talked about the physiology, pathology, causes, treatment and prevention of this problem. When a swimmer shoulder arises from training overload, these are the affected joints: glenohumeral joint, scapula-thoracal (shoulder blade and breast/chest) parts, cervical-thoracal (neck and chest) parts, acromion-clavicular (shoulder hight and collar bone) parts and sternal-clavicular (breastbone and collar bone) parts. These are the problems that can appear: - Subacromial impingement - Supraspinatus tendinopathy - Biceps tendinopathy - Association with hyperloosness / -instability The shoulder impingement is the impaction of the following structures underneath the acromion: biceps tendon, supraspinatus tendon (SSP tendon) and bursae. The shoulder is the most flexible joint of the human body. It is flexible enough to enable extreme external rotations but is stable enough to prevent dislocations/ luxation of the joint. The reason for the “swimmers shoulder” is easily described. A swimmer who trains 10 kilometers per day, 6 days a week, swims in average about 70 to 80 per cent freestyle. Assumed s/he needs about 20 strokes per 25 meters, s/he performs about 4000(!) circular movements a day and about 1 million per year. All this shows how extensively the shoulder parts are needed and used. Especially if the movements are not performed correctly and not enough prevention exercises are made on a regular basis, this can cause shoulder pain and injuries. 44,7 per cent of the affected swimmers feel the pain during the first half of the pull phase (arm makes a flexion, abduction and internal rotation), 14,3 per cent feel it during the second half of Ab sofort buchbar!

DSTV / Der Schwimmtrainer 15 Juli 2014 the pull phase (extended adduction and internal rotation rotation) and 23,2 per cent experience pain during the recovery phase (abduction and internal rotation). Shoulder pain in elite swimmers is primarily due to swim-volume-induced supraspinatus tendinopathy: 90 per cent of the swimmers on this level have shoulder complaints, 37 per cent have bilateral problems, 70 per cent have the supraspinatus tendinopathy. This all is related to training time, load and distance as well as the swimmers level. Therefore, it is very important for the swimmer to have enough but not too much strength, a good stability, mobility and a good coordination. The coach needs to set the right individual training load, adapted on the swimmers physiological, anatomical and technical preconditions and always has to consider the sensitive phases when working with children and adolescents. If shoulder problems occur, the physicians and physical therapists have to make a good analysis of where the injury is coming from and what exercises are necessary for a good treatment of the athlete. The treatment should be focused on stretching, mobilization, improving shoulder stability, strengthening the internal rotators and improving core stability. To prevent unnecessary shoulder injuries, a good swimming technique is important. This means that unilateral movements should be avoided, analysis of the swimming technique should be implemented (body roll, elbow height, body position in the water) and high training loads should be minimized. In addition, it is important to have a good body posture, enough mobility in the spine and shoulder capsule, a good muscle length (stretching), sufficient strength and coordination in the shoulder muscles (rotator cuffs, shoulder blade stabilizers) and a good core stability. Therefore, risk factors should be determined and minimized, shoulder prevention programs and a good land training should be performed and young talents should not specialize to early but get a wide and general training education instead. The focus should be placed on a right swimming technique, the improvement of coordination skills and the development of a good body structure for future higher training loads.
