En studie om transversus abdominis funktion påverkas av stabilitetsträning.
Background and purpose: Volleyball requires a lot of the human body, andeffective core stability is necessary for the athlete. Our muscles cooperate as achain of motions and core stabilization is the base for the moving muscles.The most well-known stabilization muscle is m.transversus abdominis (TrA).The purpose of the present study was to evaluate the function of TrA inSwedish female elite volleyball players and to observe the influence of eightweeks of stabilization exercise on the TrA. Method: 10 female elitevolleyball players (mean age 24,7 years, range 18-31 years) participated inthe study. TrA was measured in supine position with a pressure biofeedbackunit. Subjects were instructed to draw in the abdominal wall without movingthe pelvis and hold for 10 seconds. After eight weeks of stabilization exercisethe same test was repeated. Results: 40 % of the subjects had an insufficientfunction of TrA in the initial test. In the second test 78 % had improved theirresults. Conclusion: Stabilization exercise improves the function of TrA andshould be included in elite practise.
