      <content:encoded><![CDATA[Es wurden Knochenmineraldichte (MBD) und Gliedmasenmuskelmasse (AMM) von 62 männlichen Sportlern nationaler und internationaler Klasse im Alter von 18-25 Jahren untersucht. Diese waren 21 Judoka, 14 Karatesportler und 24 Waserballspieler. Die Kontrollgruppe bildeten 12 Nichtsportler.Alle Sportler trainierten mindestens 3 Stunden/Tag, 6 Tage/Woche. 
Ergebnisse:
Die Gesamt-BMD der Kontrollgruppe war signifikant niedriger als die der Judoka oder Karatesportler, die der Wasserballspieler unterschied sich nicht von der der Kontrollgruppe. Die AMM war in der Kontrollgruppe signifikant niedriger im Vergleich zu den drei Sportlergruppen.Die Fettmasse war bei den Wasserballspielern im Vergleich zu den Judoka und Karatesportlern höher, jedoch nicht unterschiedlich von der Kontrollgruppe. Es wird geschlussfolgert, dass Sportler, besonders in Sportarten mit hoher Auftreffbelastung, eine höhere BMD und AMM als Kontrollpersonen haben.]]></content:encoded>

      <content:encoded><![CDATA[Purpose: It is known that participating in sports can have a beneficial effect on bone mass. However, it is not well established which sport is more beneficial for increased bone mineral density (BMD) and appendicular muscle mass (AMM). This study investigated the effects of different high-intensity activities on BMD and AMM in highly trained athletes. Materials and Methods: Sixty-two male subjects aged 18-25 yr participated in the study. The sample included judo (J; N = 21), karate (K; N = 14), and water polo (W; N = 24) athletes who all competed at national and international level. Twelve age-matched nonathletic individuals served as the control group (C). All athletes exercised regularly for at least 3 h.d-1, 6 d.wk-1. Segmental, total BMD, and AMM were measured with a dual-energy x-ray (DXA) absorptiometry (Lunar Corp., Madison, WI). DXA analysis also includes bone mineral content (BMC) and fat and lean masses. Results: Total BMDC was significantly lower (mean +/- SD: 1.27 +/- 0.06 g.cm-2, P < 0.05) than either judo or karate athletes (total BMDJ (1.4 +/- 0.06 g.cm-2) and total BMDK (1.36 +/- 0.08 g.cm-2)) but not different from the W athletes (total BMDW (1.31 +/- 0.09 g.cm-2)). AMM was significantly lower in the C group compared with the three athletic groups (P < 0.05). Fat mass was higher in the W versus J and K athletes but not different from the C group (P < 0.05). Conclusions: This cross-sectional study has shown that athletes, especially those engaged in high-impact sports, have significantly higher total BMD and AMM than controls. These results suggest that the type of sport activity may be an important factor in achieving a high peak bone mass and reducing osteoporosis risk.]]></content:encoded>
