The Importance of Posture And Body Composition for the Stability and Selected Motor Abilities of Professional Handball Players

Abstract

The aim of the research was to analyze body composition, body posture and postural stability of professional male handball players and to determine the differences between players with correct and incorrect body posture, considering power of the lower limbs and agility, speed, and change of direction deficit. The study comprised 16 professional handball players. Body composition analysis was performed using the method of electrical bioimpedance. Body posture was examined using the Diers formetric III 4D optoelectronic method. Postural stability was tested via the Biodex Balance System. Players performed the following fitness tests assessing lower limb muscle power (LP, HS, CMJ), linear speed (SLS 20 m), and COD speed (Zig-Zag test, COD deficit). Only 31.25% of players demonstrated body posture with correct physiological curvatures, while 68.75% showed changes in body asymmetry. The group with correct body posture performed better in SLS 20m than the group with incorrect posture, yet in the Zig-Zag agility test, the difference in the results was not significant and this affected the COD deficit, which was higher. The vast majority of participants demonstrated postural defects and incorrect physiological curvatures of the spine. The occurrence of scoliotic posture was also observed. The body deflection angles indicated that athletes’ postural stability was good. However, it is worth noting that the majority demonstrated a tendency towards asymmetrical body deflections to the right or to the left, backwards direction. One-sided sports specialization leads to disturbances in the statics of the body, therefore, it becomes necessary to include postural re-education exercises in training.

The Association of Sagittal Spinal Posture among Elementary School Pupils with Sex and Grade

“…Results were digitally displayed after the measurement. The sagittal spinal posture of participants was measured using the Formetric 4D System (Diers, Schlangenbad, Germany), belonging to a group of non-invasive methods for diagnosing postural status, previously utilized in research [17][18][19]. The diagnostic method relied on photometry, based on the principle of triangulation.…”

Somatic characteristic, morphological asymmetry and postural stability of youth male canoeists compared to control. A cross-sectional study

“…Extreme specialisation (excessive practice of specific techniques) in sports such as fencing or canoeing can induce strong preferences for one side of the body and create asymmetric balance patterns [ 17 , 18 ]. Also, in team games like hockey or handball asymmetrical positions are often assumed what could affects body posture and its stability [ 17 , 19 ]. It is worth to know that some asymmetry level is also observed in population studies [ 20 , 21 ].…”
