Sexual Harassment and Abuse among Young Elite Athletes, Recreational Athletes, and Reference Students: A Prospective Study
Purpose: To examine the 12-months prevalence and 12-months prospective change in reported sexual harassment and abuse (SHA)-victimization among young elite athletes, recreational athletes, and reference students in three different social settings and identify the perpetrators. Methods: In total, 919 adolescents responded to an online questionnaire in 12th grade (T1) and 13th grade (T2). The sample consisted of elite athletes (n = 482) and recreational athletes (n = 233) attending Norwegian elite sport high schools (n = 26), and reference students (n = 200) attending ordinary high schools with no sport specialization (n = 6). Data were analyzed using Independent sample t-test, Pearson Chi-Square for independence/Fisher’s Exact test, McNemar test and logistic regression analysis. Results: The total 12-months prevalence of SHA was 38.6% at T1 and 35.1% at T2. Most of the participants (74.6-85.0%) reported no change in SHA from T1 to T2. The prevalence of SHA was higher for girls compared to boys, and elite athletes reported less SHA than recreational athletes and reference students, respectively. SHA occurred most often in a free time setting. Verbal SH, non-verbal SH, and physical SHA were reported by 24.6%, 27.0%, and 14.0%, respectively. Peers were reported as perpetrators by 83.1%, trainer/teacher/health personnel by 20.1%, and “other” perpetrators by 56.4%. Conclusions: As one in three elite athletes and nearly one in two recreational athletes and reference students, respectively, reported SHA-victimization within a 12-months period, well-targeted preventive measures are needed for both young athletes and non-athletes.Sexual Harassment and Abuse among Young Elite Athletes, Recreational Athletes, and Reference Students: A Prospective StudypublishedVersionPaid open acces
Experiences of Older Adults Preparing for Their First Triathlon: "A Qualitative Study of the Participation in an Endurance Training Intervention
Purpose: The overall aim of the present study was to explore the experiences of older adult exercisers participating in an individualized training program lasting 3 months preparing for completing a triathlon competition. Methods: Fourteen older Norwegian adults (median age (interquartile range, IQR) for males (N=10) and females (N=4) were 70.0 (65.0-75.5) and 57.5 (56.3-62.5) years, respectively) participated in 3-month individualized training program comprising three weekly sessions of running, cycling, and swimming. Both field- and laboratory-based testing were conducted. The participants attended two sports nutrition and competitive psychology seminars focusing on triathlon competition. The participants were interviewed in depth in three different focus groups. Thematic analysis was utilized to analyze the findings. Results: Participants improved their performance in all field-based tests. After completion of the thematic data analysis the main finding and overarching theme of well-being and being fit emerged. Additionally, three main themes were identified: 1) motivation; 2) progress and coping; and 3) breaking barriers. Conclusion: Psychological well-being and satisfaction of being fit seem to be vital to participate in a triathlon competition. Promoting specific age-appropriate participation in sports activities can be an effective strategy for promoting a healthy lifestyle among the elderly.

Is there such a thing as sustainable physical Activity?
-This study aims to assess the prevalence of different modes of commuting to school and work for 10-12year-olds and their parents; to assess the associations with demographic variables (country, sex, parental education and ethnicity) and with weight status in eight European countries. As part of the ENERGY project a cross-sectional survey was conducted in 2010 in which modes of commuting and socio-demographic variables for children (N=7903) and one of their parents (n=6455) were measured by questionnaires. Children's weight and height were objectively measured; parents self-reported their weight and height. Logistic multilevel regression analyses assessed the associations between mode of commuting and overweight. Differences between countries and differences in mode of commuting according to demographic variables were tested using χ2-test and Marascuilo's Post-hoc analysis. There were marked differences between countries, especially regarding cycling to school, which was common in The Netherlands and Norway and rare in Greece and Spain. Demographic variables were associated with mode of commuting in children and parents. Mode of commuting was not associated with being overweight in children, after adjustment for demographic variables. Bicycling to work, but not other modes of commuting, was significantly inversely associated with being overweight among parents (OR=0.74 (95%CI 0.57-0.97)). Interventions targeting active commuting may promote cycling, and should take into account the differences regarding demographic variables.Nivå

How does a lifestyle intervention during pregnancy influence perceived barriers to leisure-time physical activity? The Norwegian fit for delivery study, a randomized controlled trial
Background: To develop effective health promotional and preventive prenatal programs, it is important to understand perceived barriers to leisure-time physical activity during pregnancy, including exercise and sport participation. The aims of the present study was 1) to assess the effect of prenatal lifestyle intervention on the perceived barrier to leisure-time physical activity during pregnancy and the first year after delivery and 2) identify the most important perceived barriers to leisure-time physical activity at multiple time points during and after pregnancy. Methods: This secondary analysis was part of the Norwegian Fit for Delivery study, a combined lifestyle intervention evaluated in a blinded, randomized controlled trial. Healthy, nulliparous women with singleton pregnancy of ≤20 gestational weeks, age ≥ 18 years and body mass index ≥19 kg/m2 were recruited via healthcare clinics in southern Norway, including urban and rural settings. Participants were randomized to either twice-weekly supervised exercise sessions and nutritional counselling (n = 303) or standard prenatal care (n = 303). The principal analysis was based on the participants who completed the standardized questionnaire assessing their perceived barriers to leisure-time physical activity at inclusion (gestational week 16, n = 589) and following intervention (gestational week 36, n = 509), as well as six months (n = 470) and 12 months (n = 424) postpartum. Results: Following intervention (gestation week 35.4 ± 1.0), a significant between-group difference in perceived barriers to leisure-time physical activity was found with respect to time constraints: “... I do not have the time” (intervention: 22 vs. control: 38, p = 0.030), mother-child safety concerns: “... afraid to harm the baby” (intervention: 8 vs. control: 25, p = 0.002) and self-efficacy: “... I do not believe/think that I can do it” (intervention: 3 vs. control: 10, p = 0.050). No positive effect was seen at postpartum follow-up. Intrapersonal factors (lack of time, energy and interest) were the most frequently perceived barriers, and consistent over time among all participants. Conclusion: The intervention had effect on intrapersonal perceived barriers in pregnancy, but not in the postpartum period. Perceived barriers to leisure-time physical activity were similar from early pregnancy to 12 months postpartum.publishedVersionNivå
Normative values for musculoskeletal- and neuromotor fitness in apparently healthy Norwegian adults and the association with obesity: a cross-sectional study
Background: Up-to-date research on musculoskeletal- and neuromotor fitness (MSMF) is lacking. The aims of the present paper were to a) establish normative values of MSMF by gender and age, and b) to assess how much of the variance in MSMF can be explained by obesity in adults. Methods: A random selection of 726 Norwegians (20–65 years) participated in a national cross-sectional study. Muscular endurance, muscular strength, explosive power, flexibility and balance were assessed in addition to waist circumference (WC). Results: Females displayed significantly higher scores compared to males on muscular endurance of the back extensors and on the flexibility tests (p < 0.001). Males displayed significantly higher scores than females (p < 0.001) on handgrip strength, modified push-ups, and explosive power. An inverse association was found between age and all MSMF scores for females (Beta:−0.06–(−0.92), p ≤ 0.044) and males (Beta:−0.15–(0.91), p ≤ 0.006), where younger participants displayed higher test scores on all MSMF tests, compared to older participants. Furthermore, participants showing higher scores on WC displayed lower scores on the following MSMF tests for both females and males: muscular endurance of the back extensors, balance, flexibility of the shoulder, and explosive power (p < 0.001). Additionally, male participants with higher WC scores showed lower scores on muscular endurance of the upper body and flexibility of the hamstrings compared to males with lower WC scores (p < 0.001). Conclusions: The data provide normative values of MSMF for adults based on age and gender, and support an inverse relationship of MSMF to age and WC
