Physical activity (PA) and sedentary behavior (SB) have important implications for health benefits. A growing number of people use consumer available wearables such as activity trackers, which claim to objectively monitor PA and SB in free-living conditions. These devices could provide essential information …

BACKGROUND: Hospital stays are associated with high levels of sedentary behavior and physical inactivity. To objectively investigate physical behavior of hospitalized patients, these is a need for valid measurement instruments. The aim of this study was to assess the criterion validity of three accelerometers …

Purpose: Measurement of muscle mass is paramount in the screening and diagnosis of sarcopenia. Besides muscle quantity however, also quality assessment is important. Ultrasonography (US) has the advantage over dual-energy X-ray absorptiometry (DEXA) and bio-impedance analysis (BIA) to give both quantitative …

Rationale: Diagnosis of sarcopenia in older adults is essential for early treatment in clinical practice. Bio-electrical impedance analysis (BIA) may be a valid means to assess appendicular lean mass (ALM) in older adults, but limited evidence is available. Therefore, we aim to evaluate the validity …

Introduction In the Netherlands, hospitals have difficulty in implementing the formal procedure of comparing radiation dose values to Diagnostic Reference Levels (DRLs).

Background: Hypothyroidism is a common endocrine disorder and the standard treatment is replacement therapy with levothyroxine (LT4). Although many hypothyroid patients improve upon treatment with LT4, a proportion seems to experience residual hypothyroid complaints despite treatment, even when plasma …

INTRODUCTION: In the Netherlands, hospitals have difficulty in implementing the formal procedure of comparing radiation dose values to Diagnostic Reference Levels (DRLs). METHODS: To support the hospitals, train radiography students, and carry out a nationwide dose survey, diagnostic radiography students …

Background: Aerobe fitness (AF) is an important component of physical fitness of children and adolescents. To assess the AF, the 20-m Shuttle Run Test (SRT-20) is often used. Unfortunately, there is frequently a lack of an at least 22 m physical facility to utilize this test indoor. By still using the …

From previous research in the western Wadden Sea it is clear that mussel plots are important hotspots for biodiversity. When the density of a mussel plot is higher, the biodiversity appears to be higher as well. This final thesis project was a part of the bigger project, ‘Added value with Mussels’, executed …
