Alpine skiers also had higher grip strength than controls, selleck inhibitor and higher knee extension torque compared with all other groups. Male alpine skiers had significantly higher body mass than controls, and also had greater lean mass than the other athletes and the controls. All male athletes began training at a similar age (7.9 years–9.0 years), but alpine skiers and swimmers had significantly higher

total training volume than soccer players and alpine skiers spent more time weight training than both soccer players and swimmers. Alpine skiers had significantly higher grip strength than all other groups and significantly higher knee extension torque than controls. In the female cohort, alpine skiers had 28% (75.1 mm2) higher Tt.Ar than controls after adjusting for height, body mass, and lean mass. In the male cohort, alpine skiers had 24% (42 mg HA/cm3) higher Tb.BMD and 14% (57.3 mm2) higher Tt.Ar compared with swimmers. Tb.N was 14% (0.28 mm− 1) and 18% (0.35 mm− 1) Selleck AZD6244 higher in the soccer players compared with swimmers and controls, respectively. Tb.Sp was 20% (0.070 mm

to − 0.073 mm) higher in both swimmers and controls compared with soccer players. Alpine skiers had 60%, 75%, and 44% (1477 N, 1685 N, and 1205 N) higher failure load indicating stronger bones than soccer players, swimmers, and controls, respectively (Table 2). Results of the HR-pQCT tibia scans for each sex and group are presented in Table 3. In the female cohort, Tt.BMD was approximately 24% higher (68.0 mg HA/cm3 aminophylline and 65.7 mg HA/cm3) in alpine skiers and soccer players, respectively, compared with swimmers. A similar result was observed for Tb.BMD, as alpine skiers and soccer players had 25% and 17% higher Tb.BMD (45.2 mg HA/cm3 and 30.7 mg HA/cm3), respectively, than swimmers. Conversely, swimmers had 1% higher Ct.BMD

(6.7 mg HA/cm3) compared with soccer players. Ct.Th was 23.8%–29.5% higher (0.25 mm–0.31 mm) in alpine skiers and soccer players compared with swimmers. Regarding bone micro-architecture, controls and swimmers had 16%–23% (0.06 mm–0.091 mm) higher Tb.Sp, respectively, than alpine skiers. The general trend for augmented bone parameters in alpine skiers and soccer players compared with swimmers was also observed with failure load, as soccer players and alpine skiers had 15%–26% (942 N–1634 N) greater failure load than swimmers. Tb.BMD was 20% (38.7 mg HA/cm3) higher in alpine skiers compared with swimmers. Tb.N was 22% (0.38 mm− 1) higher in male soccer players compared with swimmers, and Tb.Sp was 22% (0.105 mm) lower in male soccer players compared with swimmers. Male alpine skiers and soccer players had 28%–38% higher failure load (718 N–2654 N) than swimmers. Any predictors discussed in this section are those with an F-value change that is statistically significant at the p < 0.05 level, unless otherwise stated. All results pertaining to the regression analysis can be found in Table 4.
