摘要：Straton Alexandru,Deliu Dan,Gidu Diana.Limbs utilization preference effect on trunk muscles maximal isometric strength production in Romanian sportswomen.Background: Most problems encountered at the level of vertebral column in sportswomen is generated by asymetrical movements at the level of the trunk directly linked by preferential utilization of either superior or inferior limbs in sports training and competition.Aims: The aim of this study is to determine the effect of limbs utilization preference on trunk muscles maximal isometric strength production in Romanian sportswomen.Methods: This study used 15 Romanian sportswomen,white caucasian,divided in 5 handball players,5 soccer players,5 track and field athletes (triple jump).Body height was estimated with an error of 0,5cm.and body weight was evaluated with a calibrated digital scale (Exacta,Germany),with an error of 0.25 kilograms.The body fat percentage was estimate using a bioelectric impedance method (Omron BF-306).Maximal isometric strength of the lumbar/thoracic column was measured with special machines in all three planes – flexion with David F130 Lumbar/Thoracic Flexion at 30º angle and extension with David F110 Lumbar/Thoracic Extension at 30º angle,in sagittal plane – right lateral flexion and left lateral flexion with David F150 Lumbar/Thoracic Lateral Flexion at 0º angle,in frontal plane – right lateral rotation and left lateral rotation with David F120 Lumbar/Thoracic Rotation at -30º angle,in transversal plane.Results: Handball players have a significantly higher maximal isometric strength for left lateral flexion then right lateral flexion (t=6,816) and track and field athletes have a significantly higher maximal isometric strength for right lateral rotation then left lateral rotation (t=5,662).Conclusions: Sportswomen will develop the trunk strength according to preferential utilization of either superior and inferior limbs,but only in sports with strong asymetrical movements.
