Physical fitness and physical activity in Norwegian home guard soldiers: a cross-sectional and method comparison study
MetadataShow full item record
INTRODUCTION: Physical fitness is an important attribute in soldiers because military work may be physically demanding. To ensure that military personnel are “fit to fight”, soldiers are typically selected and evaluated based on fitness tests, and physical training and physical activity are emphasized to maintain or develop physical fitness. Existing literature has primarily described fitness and activity levels in full-time soldiers, while reserve soldiers are less frequently investigated. No previous studies have reported physical fitness or physical activity levels in the Norwegian Home Guard (HG) force. When describing fitness and activity levels, it is important that the validity and reliability of the measurement tools are known, preferably for the population of interest. Some of the frequently used methods have not been sufficiently evaluated for validity and reliability in military populations, and such studies are therefore needed. AIMS: The main aim of this thesis is to describe physical fitness and physical activity in a nationally representative sample of Norwegian HG soldiers. An additional aim is to investigate the validity and reliability of two primary outcome measures from the HG study: the 20 meter shuttle run test (20 m SRT) for aerobic fitness and a bioelectrical impedance analysis (BIA) method for body fat estimations.Paper I: Aandstad A., Holme I., Berntsen S., Anderssen S.
