- Female endurance athletes are considered a high-risk group for developing Relative Energy Deficiency in Sport (REDs). Due to the lack of educational and behavioral intervention studies, targeting and evaluating the effects of the practical daily management of REDs, we developed the Food and nUtrition for Endurance athletes—a Learning (FUEL) program, consisting of 16 weekly online lectures and individual athlete-centered nutrition counseling every other week. We recruited female endurance athletes from Norway (n = 60), Sweden (n = 84), Ireland (n = 17), and Germany (n = 47). Fifty athletes with symptoms of REDs and with low risk of eating disorders, with no use of hormonal contraceptives and no chronic diseases, were allocated to either the FUEL intervention (n = 32) (FUEL) or a 16-week control period (n = 18) (CON). All but one completed FUEL, while 15 completed CON. We found strong evidence for improvements in sports nutrition knowledge, assessed via interviews, and moderate to strong evidence in the ratings concerning self-perceived sports nutrition knowledge in FUEL versus CON. Analyses of the seven-day prospective weighed food record and questions related to sports nutrition habits, suggested weak evidence for improvements in FUEL versus CON. The FUEL intervention improved sports nutrition knowledge and suggested weak evidence for improved sports nutrition behavior in female endurance athletes with symptoms of REDs.

- Tennis is an all-year racket sport requiring qualities such as speed, agility, flexibility, and endurance, as competitions may last up to five hours.Elite players have an estimated daily need of carbohydrate (CHO) between 6-10 g/kg to sustain high amounts of training and frequent competitions. Low energy availability (LEA), over time, may impair both health and performance. LEA may cause metabolic suppression and altered hormone levels via hypothalamic–pituitary– gonadal axis (HPG). Female athletes with LEA have an increased risk of developing menstrual dysfunction, low bone mineral density (BMD), disordered eating behavior (DE) and an eating disorder (ED). This article provides a case-study of an internationally ranked female tennis player, with a recent performance-driven weight loss of 11 kg. She was diagnosed with functional hypothalamic primary amenorrhea (FHA) and anorexia nervosa (AN). The predetermined goal was to return to play and the treatment was based on the guidelines for relative Energy Deficiency in Sport (REDS-CAT). After three years of multidisciplinary interventions, the athlete safely returned to play. Her weight and body composition improved, her menstrual cycle was normalized and the diagnostically scores of AN indicated non-clinical significance. The multidisciplinary treatment enabled the athlete to return to play despite several years of LEA and AN.

- Purpose: To investigate the acute exercise effects of dynamic standing exercise (DyS) on blood glucose and blood lactate among children and adolescent with cerebral palsy (CP) who are non-ambulant. Methods: Twenty-four participants with CP who are non-ambulant performed 30 minutes of DyS using a motorized device enabling assisted passive movements in an upright weight-bearing position. Capillary blood-samples were taken from the fingertip for measurement of blood glucose and blood lactate at rest and at the end of exercise. Results: At rest, the participants had hyperlactatemia that was unaffected after exercise presented as median and interquartile range at rest 1.8 [1.3:2.7] mmol/L and after exercise 2.0 [1.1:2.5] mmol/L. Children and adolescents with GMFCS-E&R V had higher lactate levels at rest (2.5 [1.8:2.9] vs 1.4 [1.0:2.0]; p=0.030) and after exercise (2.3 [2.0:2.6] vs 1.2 [0.9:2.2]; p=0.032) compared to children and adolescents with GMFCS-E&R IV respectively. A statistically significant larger decrease in blood lactate levels after exercise was observed in children and adolescents with higher resting blood lactate levels (rho=0.56;p=0.004). There were no statistically significant changes in blood glucose. Conclusions: Forty percent of the participants had mild hyperlactatemia at rest and participants with the highest blood lactate levels at rest had the greatest decrease in blood lactate levels after one bout of exercise. Children and adolescents with classified into higher level of GMFCS-E&R had higher blood lactate levels. More studies are needed on how to prevent chronically high resting levels of lactate with exercise in children with CP who are non-ambulant.

- BACKGROUND: Disordered eating (DE) behaviors are relatively common among high-level dancers, especially in classical ballet. At the same time, interventions aimed at reducing DE behaviors in this population are scarce. METHODS: An 8-week exploratory preventive interven-tion for DE behaviors was carried out in a high-level ballet school for 40 teenagers aged 12-15 years (77.5% female). Both risk factors (perfectionism) and potentially protective factors (self-esteem, self-compassion) for the development of DE behaviors were considered. The intervention was created specifically for this study and consisted of five cognitive behavior therapy (CBT) work-shops and four nutrition workshops. Additional compo-nents included newsletters for pupils and educational sessions and social media interactions with staff and parents. The intervention comprised two phases (control and intervention periods), with students acting as their own controls. Standardized questionnaires were com-pleted before and after both phases. RESULTS: Ques-tionnaire results did not indicate any changes in reported perfectionism, self-esteem, or self-compassion, nor were symptoms of DE affected during either the control or intervention periods. CONCLUSIONS: The intervention did not yield any discernible impact. How - ever, it was affected by the onset of the COVID-19 pan-demic, which limits our ability to draw conclusions about intervention effectiveness. Evaluations with pupils offer several considerations for future improvements.

Tidskriftsartikel (refereegranskat)abstract
- Background: Severe to profound intellectual disability (SPID) is associated with multiple neurodevelopmental disorders and problems. In the most severe cases, the term profound intellectual and multiple disabilities (PIMD) is used. This study aimed to explore the co-occurring disorders and neurodevelopmental problems in a sample of twins where the proband had SPID. Method: Within a population-based sample of (30 312) twins, 20 individuals with a national patient register SPID diagnosis were identified. Parent telephone interview data (screening of neurodevelopmental disorders) and register data (APGAR, birth weight, intellectual disabilities, epilepsy, motor and sensory disorders) were gathered for probands and co-twins. Results: The 20 individuals with SPID all had between one and five additional disorders or problems, with autistic traits, motor problems and epilepsy being the most common. Clear discordance was found for ID and all additional disorders and problems between probands with SPID and their non-SPID co-twins. Conclusion: Children with SPID almost never present without neurodevelopmental and/or sensory and/or motor comorbidities. This heterogeneity should be reflected in clinical routine and in research targeting individuals with SPID. The results support a previously suggested conceptualization of a S/PIMD “spectrum”. Autism may be considered for inclusion in future elaborations of such a S/PIMD spectrum.
