Physical activity and Sports Medicine with focus on prevention
Our research focus is in the area of physical activity, physical exercise and sports medicine. We study the link between physical activity and health, the effect of exercise interventions on habitual physical activity levels, and the prevention of sports injuries. Our research combines epidemiology, method development and intervention research.
Our vision is to increase health, especially among individuals with risk factors, disabilities or injuries through high quality epidemiological and intervention/implementation research in the area physical activity and sports medicine.
The BETA project
The BETA-study is a joint project with Professor Ståhle, Associate professor Franzén and Associate professor Hagströmer.
The project aims to translate basic neuroscience into applied research and clinical understanding and implements the evaluation methods and training program into clinical practice. We hypothesize that a new conceptual framework for balance training, emphasizing critical aspects of balance control specifically related to disease symptoms through highly challenging, progressive and varied exercises, will improve balance and gait performance in elderly with osteoporosis or Parkinson’s disease. We predict that increased balance control following training will lead to increased levels of physical activity and an improved health related quality of life. We have been successful in receiving grants for conducting the study as well as for PhD students and postdocs.
Our group is responsible for the physical activity and preventive arm of the project, including one PhD student, Håkan Nero. In addition we are developing and testing methods for assessment of physical activity, such as using accelerometry, in individuals with impaired gait.

ABC study (Attitude, Behavior and Change)
The Attitude, Behavior and Change study (ABC) is a cross-sectional and longitudinal research project on health behaviors with data collection by questionnaire and physical activity monitoring. The study includes a random sample of around 1 500 adults, 18-74 years, selected from the Swedish population register, with data collected in 2001/2002 and 2007/2008. A follow-up of the sample is in planning.
The study was originally initiated by Associate professor Michael Sjöström at the Department of Biosciences and Nutrition, Karolinska Institutet and is now a collaborative project between the two departments.
For the first time, physical activity and sedentary behavior was measured using objective methodology, giving results that is thought provoking. The findings from this project have revealed both international and national publicity. We have for example been invited to present at conferences and symposium. The methodology used has been set as a standard for assessment of physical activity levels in the European Union (the ALPHA project). The Swedish news Rapport and Vetenskapens värld have reported from the study.

Screening of athletes, sport injury registration and prevention (2013-2016)
The long term goal of this project is to reduce the risk, for adolescent elite athletes, to sustain injuries (overuse and acute), recurrent injury and pain that reduces participation in sports and thereby enhance increased awareness, performance and health. Further on, a long term goal is to reduce health care costs. Ultimately, the goal is to deepen the knowledge on how to make adolescent sport participation on elite level more safe and healthy by scientifically develop theoretical as well as clinical models regarding risk factors and injury prevention
The short term goals are to increase the understanding of the injury panorama and to study risk factors for injuries in different sports and to improve the knowledge in injury prevention in coaches and medical staff. We also foresee a need to develop medical teams located at the Swedish National Sports High Schools, in order to facilitate quick and safe diagnosis and rehabilitation of injuries.
Approximately 500 adolescent elite athletes in handball, athletics, cross-country skiing, orienteering, down-hill skiing, American football, wakeboard, bowling, cycling, golf, triathlon, and canoeing, from 20 Swedish National Sports High Schools are enrolled in the study. A prospective design is applied following the athletes over 1-2 years. Baseline data are collected at the start of each semester and incidence and prevalence data on injuries, training volume and intensity are collected by using self-reporting weekly web-based questionnaire. In addition, the athletes undergo a movement screening (9+screening battery) once every semester, to collect data on asymmetries and dysfunctions. Data collection will end in December 2015.
The project is financed by The Swedish National Centre for Research in Sports, Karolinska Institutet and the Swedish Sports Confederation.

Hormonal influences on physical exercise
The overall aim of this project is to study the effect of oral contraceptives on postural control, muscle strength and premenstrual symptoms (PMS) in moderately physically active women of fertile age. Oral contraceptives are used to similar extent by athletes as by a nonathletic population. Still, there is lack of studies investigating the effect of oral contraceptives on physical performance and on the effect of PMS symptoms. Earlier studies have showed oral contraceptives to be protective for sports injuries but the mechanism for this is still not fully elucidated. Possible explanations could be hormonal influence on muscles, tendons and ligaments.
A further aim of this project is to study mRNA and protein levels of sex hormone receptors in skeletal muscle tissue of women during three different phases of the menstrual cycle. Expression of estrogen receptors in human skeletal muscles on both mRNA and protein levels have recently been described. However, levels of sex hormone receptors in skeletal muscle during the menstrual cycle have not earlier been studied.
The project is a collaboration between The Division of Physiotherapy (Associate professor Cecilia Fridén), the Division of Obstetrics and Gynecology (Professor Angelica Lindén- Hirschberg), Karolinska Institutet and the Division of Obstetrics and Gynecology (Professor Torbjörn Bäckström), Umeå University Hospital. The project has one PhD student, Linda Ekenros.
The project is financed by Swedish National Centre for Research in Sports and the Swedish Research Council
