[Effects of soccer-specific strains on the locomotor system].
OBJECTIVE
Soccer as a Stop-and-Go-sport goes along with a high level of physical strain on the locomotor system. Compared to similar kinds of sports, soccer is characterized by a high prevalence of overloads/injuries in the pelvic region. Since soccer frequently involves one-sided shot-training, modifications in the pelvic statics are possible.


METHODS
In a pilot study including 15 football-players-FP (age 26.9 +/- 3.1 yrs; 4.4 +/- 0.4 training units/week+ 1 leaque game) the pelvic statics was measured using the 3-d-recording system CMS70 (Zebris, Germany) directly before and after a defined shot training. The positions of the right and the left posterior superior iliac spines - PSIS were compared. Additionally, the stiffness of selective muscles was analyzed.


RESULTS
Before intervention the right PSIS was heightened in 8 FP. In 4 FP the pelvic statics was balanced and in 3 FP the right PSIS was abased. After the shot training, the pelvic statics was balanced in 4 FP. In contrast, 10 FP showed a higher right PSIS and 1 FP had a lower right PSIS. However, modifications of the pelvic statics were detected in all directions.


CONCLUSIONS
Our study demonstrates modification of the pelvic statics by asymmetric soccer-specific strains, but the reactions were individually different. It is possible, that changes in the pelvic statics may lead to changed function or overstrain of advertising muscles.
