Descriptive epidemiology study. Online survey. Group fitness instructors from three fitness centre companies in Norway (n = 1473). Assessment of independent variables: questions regarding duration of working as a group fitness instructor, weekly instruction and exercise loading and modality, instruction-related injuries, musculoskeletal pain, use of alcohol, tobacco, snuff, menstrual dysfunction and disordered eating (Eating Disorder Inventory, EDI). The respondents were divided into high instruction loading (HIL), ≥5 h/w with instruction; and low instruction loading (LIL), <5 h/w with instruction). The response rate was 57% (n = 837). Mean total loading (instruction and exercise) was 11.8 h/w and 6.3 h/w in the HIL and LIL groups (p < .001), respectively. The prevalence of acute (9% vs. 6%, p < .05), overuse (38% vs. 24%, p < .001)...

Adult females with DSM-IV anorexia nervosa (AN), bulimia nervosa (BN) or eating disorders not otherwise specified (EDNOS) (n=59, mean(SD) age 30.1(8.5) yrs and ED duration 14.3 yrs) and non-clinical age-matched controls (n=53, mean(SD) age 31.3(8.3) yrs) accepted participation in this cross-sectional study. Measurements included accelerometer assessed and self reported amount of different types of physical activities, VO2max on treadmill, 1RM in leg and chest press, and BMD in lumbar spine (L2-L4), femur neck and total body analyzed by DXA. Muscular strength and BMD were lower in patients with AN, not in patients with BN or EDNOS, compared to controls. Aerobic fitness did not differ between patients and controls. BMD in the patients was positively ...

Group fitness instructors representing the three largest fitness center companies in Norway (n = 837, response rate: 57%) completed a questionnaire through Questback (www.questback.com). The questionnaire contained items regarding gender, age, educational background, exercise behavior, and knowledge of recognition and response to DE. Eighty-nine percent of the respondents reported knowledge about symptoms of DE, 29% was classified with adequate DE knowledge skills. Forty-nine percent of the instructors reported current concern about DE among one or more members, 47% reported knowledge about how to recognize and respond to DE, and 37% reported knowledge about their fitness center&amp;amp;amp;amp;amp;#39;s guidelines for approaching DE concerns. The level of formal education in sports and exercise, and a history of self-reported eating disorder, but not fitness instructor experience, were explanatory factors for knowledge about DE symptoms. Both exercise specific educational level and instructor experience were explanatory variables for knowledge about recognition of and response to DE concerns. Implications of the findings include a need for increased confidence among group fitness instructors regarding how to approach DE concerns, increased awareness of excessive/compulsive exercise as a symptom of DE, and enhanced dissemination of existing guidelines for managing DE concerns among members and/or staff. © 2014 Wiley Periodicals, Inc.

The aim of this study was to investigate the prevalence of UI among female group fitness instructors, including Pilates and yoga teachers. This was a cross-sectional study of 1,473 instructors representing three of the largest fitness companies recruited from 59 fitness centers in Norway. They filled in an online survey (Questback) about general health, educational background, and number of hours teaching per week. Prevalence of UI was evaluated by the International Consensus on Incontinence Questionnaire, short form (ICIQ-UI SF). Three out of 152 men (2%) reported UI. Six hundred eighty-five women, mean age 32.7 years (range 18-68) answered the questionnaire. 26.3% of all the female instructors reported to have UI, with 21.4% reporting leakage ≥ once a week, 3.2% 2-3 times/week and 1.7% ≥ once per day. 24.4% reported the leakage to be small to moderate and the bother score was 4.6 (SD 2.4) out of 21. 15.3% reported leakage during physical activity and 10.9% when coughing/sneezing. 25.9% of yoga and Pilates instructors reported UI. This is the first report on UI among fitness instructors and the results indicate that UI is prevalent among female fitness instructors, including yoga and Pilates teachers. More information about this topic seems to be important in the basic education of fitness instructors.

Improved V[Combining Dot Above]O2max and time trial performance with more high aerobic intensity interval training and reduced training volume: a case study on an elite national cyclist. J Strength Cond Res 26(10): 2705-2711, 2012-The present study investigated to what extent more high aerobic intensity interval training (HAIT) and reduced training volume would influence maximal oxygen uptake (V[Combining Dot Above]O2max) and time trial (TT) performance in an elite national cyclist in the preseason period. The cyclist was tested for V[Combining Dot Above]O2max, cycling economy (Cc), and TT performance on an ergometer cycle during 1 year. Training was continuously logged using heart rate monitor during the entire period. Total monthly training volume was reduced in the 2011 preseason compared with the 2010 preseason, and 2 HAIT blocks (14 sessions in 9 days and 15 sessions in 10 days) were performed as running. Between the HAIT blocks, 3 HAIT sessions per week were performed as cycling. From November 2010 to February 2011, the cyclist reduced total average monthly training volume by 18% and cycling training volume by 60%. The amount of training at 90-95% HRpeak increased by 41%. V[Combining Dot Above]O2max increased by 10.3% on ergometer cycle. TT performance improved by 14.9%. Cc did not change. In conclusion, preseason reduced total training volume but increased amount of HAIT improved V[Combining Dot Above]O2max and TT performance without any changes in Cc. These improvements on cycling appeared despite that the HAIT blocks were performed as running. Reduced training time, and training transfer from running into improved cycling form, may be beneficial for cyclists living in cold climate areas.

A total of 722 adolescents aged 12-18 years (response rate: 83%) filled out a questionnaire containing the Drive for Muscularity Scale, Eating Disorders Inventory subscales Drive for Thinness (EDI-DT), Body Dissatisfaction (EDI-BD) and Bulimia (EDI-B), and questions about amount of and motives for physical activity. Eating Disorders Inventory subscale scores were higher, and Drive for Muscularity Scale Score (DMS) scores were lower among girls compared with boys. EDI and DMS were correlated with motives for, but not amount of, physical activity. EDI and DMS were associated in boys, not girls. The associations between EDI and DMS among boys call for a wider approach when examining ED among boys.
