In male handball, limited knowledge exists about the body posture and postural control in correlation to their injury occurrence and their impact on physical constitution. 91 male handball players participated and were asked about playing position and years, NSAIDs intake, sustained injuries and therapy duration. A three-dimensional back scanner and a pressure measuring plate were used. Shoulder injuries cause a differing scapular height and increase the vertebrae rotation in correlation to playing years. Lower limb injuries lead to a decrease on the Centre of Pressure (CoP) with growing game experience. Wing players show the lowest injury risk. Lower limb and shoulder girdle are mostly affected regarding the incidence of injuries. Pivot players suffer most injuries in the lower limb area (59%), whereas wing players mostly have shoulder injuries (19%). Being injured, 21% of the players continue playing, 79% pause for a minimum of six months (25%). No correlation can be determined between level of profession, use of NSAIDs and body posture or postural control. Playing position, employment situation or NSAIDs have no influence on type of injury, body posture or postural control. While shoulder injuries can be recognized in the vertebrae area, lower limb injuries can affect the CoP.
Background: Well defined constitutional parameters support the physical fatigue resistance in handball to maintain the performance level for the majority of actions. Ideal constitutional conditions are necessary to achieve these physiological advantages in handball. But limited knowledge exists about the upper body posture or the postural control in correlation to the Body Mass Index (BMI), playing years, playing position and throwing arm in professional male handball. Methods: Ninety-one male handball players participate (24.1 ± 5.9 years; playing experience 16.6 ± 5.7 years). A three-dimensional back scanner and a pressure measuring plate were used. Results: Correlations between BMI and upper body posture and postural control were not significant. Same counts for the comparison between the left and right throwing arm according to upper body posture and postural control (p ≥ 0.05). Correlations between the years of playing can be found at pelvis height (p ≤ 0.04) and for the length of the Center of Pressure (CoP) (p ≤ 0.01). Wing players are 6.5-8.5 cm smaller. The playing position is independently of BMI, age or upper body posture (p ≥ 0.05). Backcourt players have a higher load of the left and a lower load of the right foot compared to wing players (p ≤ 0.001). Left-right comparison (p ≤ 0.001/ 0.01) can be seen in pivot player (covered area), backcourt player (weight distribution left/right [rear] foot), wing player (weight and force distribution left/right foot, covered area). Conclusion: Goalkeeper, Backcourt and pivot players are taller and heavier than wing players. These physiological demands are not detectable in the upper body posture and slightly in postural control. Wing players have the most asymmetric load distribution and the longest length of CoP. Since goalkeepers do not differ from pivot or backcourt players, this can be lead back to the same training.
