    Description: Leg dominance has been reported as one potential risk factor for lower-limb injuries in recreational downhill skiers. The current study proposed and tested two possible mechanisms for a leg dominance effect on skiing injuries—imbalance of the knee muscle strength and bilateral asymmetry in sensorimotor control. We hypothesized that the knee muscle strength (Hypothesis 1; H1) or postural control (Hypothesis 2; H2) would be affected by leg dominance. Fifteen well-experienced recreational downhill skiers (aged 24.3 ± 3.2 years) participated in this study. Isometric knee flexor/extensor muscle strength was tested using a dynamometer. Postural control was explored by using a kinematic principal component analysis (PCA) to determine the coordination structure and control of three-dimensional unipedal balancing movements while wearing ski equipment on firm and soft standing surfaces. Only H2 was supported when balancing on the firm surface, revealing that when shifting body weight over the nondominant leg, skiers significantly changed the coordination structure (p 〈 0.006) and the control (p 〈 0.004) of the lifted-leg movements. Based on the current findings, bilateral asymmetry in sensorimotor control rather than asymmetry in strength seems a more likely mechanism for the previously reported effect of leg dominance on lower-limb injury risk in recreational downhill skiers.

    Description: The present study examines motives for cycling in the alpine region and focuses on the relative importance of health promotion with respect to other motives. Furthermore, the influences of person-specific characteristics on the rank of the motives are examined, and possibilities for advertising bike tourism based on these motives and characteristics are derived. By applying a quantitative approach, a total of 175 cyclists were surveyed using questionnaires on person-specific characteristics, motives, and their relevance for alpine cycling. Data analysis revealed that health promotion is the most important motive for alpine cycling after fun and action as well as nature experience. Further health-related motives such as stress reduction are also perceived as important. The social component, on the other hand, was given the least priority. The results also showed that person-specific characteristics influence the relative importance of motives. For example, elderly persons and people with children perceive the motive of health promotion as the most important. The study shows that the health-promoting effect of alpine cycling is noticed and may be further encouraged. This study demonstrates that alpine cyclists are a heterogeneous group and that health benefits are perceived by various sub-groups therein. Therefore, any marketing for alpine cycling needs to reflect the diversity of cyclists, and approaches need to be adapted according to the respective target group.
