| 1 | Limb symmetry index in competitive alpine ski racers:Reference values and injury risk identification according to age-related performance levels显示文摘Purpose: The aims of this study were to assess differences of limb symmetry index(LSI) in strength-and coordination-related tasks between high-level, competitive, noninjured ski racers of different age-related performance levels and to prospectively assess limb differences as a possible risk factor for traumatic and overuse injury in youth ski racers.Methods: The study(Study 1) included 285 high-level competitive ski racers(125 females, 160 males) of 3 age-related performance levels and based on the school system: 95 youth(10à14 years, secondary modern school), 107 adolescent(15à19 years, grammar school), and 83 elite athletes(20à34 years). To investigate the second aim(Study 2), 67 of the 95 youth athletes were included and any traumatic or overuse injuries were prospectively recorded over 2 seasons. All athletes performed 4 unilateral tests(strength related: one-leg counter movement jump(OL-CMJ) and one-leg isometric/isokinetic press strength test(OL-ILS); coordination related: one-leg stability test(OL-ST) and one-leg speedy jump test(OL-SJ)). The LSI was calculated by dividing the dominant leg by the nondominant leg and multiplying by 100. Kruskal-Wallis H tests and binary logistic regression analyses were conducted.Results: There were significant differences between the LSI of the 3 age-related performance-level groups only in the strength-related tests: the OL-CMJ(x2(2, 285) = 9.09; p = 0.01) and the OL-ILS(x2(2, 285) = 14.79; p < 0.01). The LSI for OL-ILS was found to be a significant risk factor for traumatic injury in youth ski racers(Wald = 7.08; p < 0.01). No significant risk factors were found for overuse injuries.Conclusion: Younger athletes display slightly greater LSI values only in the strength-related tests. The cut-off value of limb differences of <10%for return to sport decisions seems to be appropriate for elite athletes, but for youth and adolescent athletes it has to be critically discussed. It seems to be necessary to define thresholds based on specific performance tasks(strength vs. coordination related) rather than on generalizations,and age-related performance levels must be considered. Limb differences in unilateral leg extension strength represent a significant injury risk factor in youth ski racers. | Lisa Steidl-Müller Carolin Hildebrandt Erich Müiller Christian Fink Christian Raschner | 2018 | Journal of Sport and Health Science2018，7，4： | 6 |
| 2 | Beijing 2022 Winter Olympic Games:Commitments to science and public health显示文摘The Beijing 24th 2022 Winter Olympic Games present a unique opportunity to promote the spirit and values of the Olympic Games in relation to their impact on physical activity and global health,sports medicine,and sports performance.The 2022 Winter Olympic Games mark the 98th year since the first Winter Games were held in Chamonix,France,in 1924.The inaugural Winter Olympic Games sponsored 16 events,and 250 athletes from 16 nations participated.1 In contrast,the Beijing 2022 Winter Olympic Games will sponsor 109 events. | Yu Liu Barbara E.Ainsworth Erich Müller | 2022 | Journal of Sport and Health Science2022，11，1： | 5 |
| 3 | Infectious, atopic and inflammatory diseases, childhood adversities and familial aggregation are independently associated with the risk for mental disorders: Results from a large Swiss epidemiological study显示文摘AIM To examine the associations between mental disorders and infectious, atopic, inflammatory diseases while adjusting for other risk factors.METHODS We used data from PsyC oL aus, a large Swiss Population Cohort Study(n = 3720; age range 35-66). Lifetime diagnoses of mental disorders were grouped into the following categories: Neurodevelopmental, anxiety(early and late onset), mood and substance disorders. They were regressed on infectious, atopic and other inflammatory diseases adjusting for sex, educational level, familial aggregation, childhood adversities and traumatic experiences in childhood. A multivariate logistic regression was applied to each group of disorders. In a complementary analysis interactions with sex were introduced via nested effects. RESULTS Associations with infectious, atopic and other chronic inflammatory diseases were observable together with consistent effects of childhood adversities and familial aggregation, and less consistent effects of trauma in each group of mental disorders. Streptococcal infections were associated with neurodevelopmental disorders(men), and measles/mumps/rubella-infections with early and late anxiety disorders(women). Gastric inflammatory diseases took effect in mood disorders(both sexes) and in early disorders(men). Similarly, irritable bowel syndrome was prominent in a sex-specific way in mood disorders in women, and, moreover, was associated with early and late anxiety disorders. Atopic diseases were associated with late anxiety disorders. Acne(associations with mood disorders in men) and psoriasis(associations with early anxiety disorders in men and mood disorders in women) contributed sex-specific results. Urinary tract infections were associated with mood disorders and, in addition, in a sex-specific way with late anxiety disorders(men), and neurodevelopmental and early anxiety disorders(women).CONCLUSION Infectious, atopic and inflammatory diseases areimportant risk factors for all groups of mental disorders. The sexual dimorphism of the associations is pronounced. | Vladeta Ajdacic-Gross Aleksandra Aleksandrowicz Stephanie Rodgers Margot Mutsch Anja Tesic Mario Müller Wolfram Kawohl Wulf R?ssler Erich Seifritz Enrique Castelao Marie-Pierre F Strippoli Caroline Vandeleur Roland von K?nel Rosa Paolicelli Markus A Landolt Cornelia Witthauer Roselind Lieb Martin Preisig | 2016 | World Journal of Psychiatry2016，6，4： | 2 |
