Osteoporose bei Querschnittslähmung: Effekte sportartspezifischer Belastungen und eines sechsmonatigen Interventions- trainingsprogramms auf die Knochendichte und den Knochenstoffwechsel unterhalb der Lähmungshöhe bei koreanischen Rollstuhlathleten und Rollstuhlfahrern ohne Behindertensport

The aim of this study was to find out what stress stimuli have an impact in the various wheelchair sports on the osteological status in paraplegics. The target group had an intervention group from wheelchair to a 24-week training intervention were subjected to measure the bone status with wheelchair effectively. Method: Measurement of the bone mineral density (BMD) on the femoral neck and the lumbar spine, measurement of the osteoblast marker (BALP, ALP and OC), the osteoclast marker (DPD and NTx) and the hormone (Vt. D, PTH and Ca). 36 wheelchair athletes (18 basketballs and 18 marathons) for the cross-sectional study and 20 paraplegics without sports for the intervention study were measured. Result: At the lumbar spine bone density was found a significantly higher in the wheelchair basketball group. At the femoral neck in contrast, showed no difference between the groups of athletes. In the intervention study for paraplegics without sports came after the training intervention in a slight but not significant increase in bone density values. The concentrations of DPD and NTx decreased with the basketball players. The concentrations of BALP and ALP was increased in the basketball group, but increased in the OC Marathon drivers. There was no significant difference. In the intervention group, there were no significant positive changes. Core essence: With these results it was found that the frequent exercise of a versatile ball sports such as wheelchair basketball can be a prevention of osteoporosis in paraplegia. This finding was indirectly confirmed by our intervention study, conducted that are in fact minimized by the regular training in the upper extremities and a bone density loss with long-term training in a positive direction can be. There was, however, with respect to the bone metabolism through the sport-specific burden and the upper body muscles activity not determine whether the concentration prevented the bone loss markers or markers of bone formation can be activated.
