Background: Patients with chronic obstructive pulmonary disease (COPD) demonstrate reduced levels of daily physical activity (DPA) compared to healthy controls. This results in a higher risk of hospital admission and shorter survival. Performing regular DPA reduces these risks. Objective: To develop …

Background: The ability to generate muscle strength is a pre-requisite for all human movement. Decreased quadriceps muscle strength is frequently observed in older adults and is associated with a decreased performance and activity limitations. To quantify the quadriceps muscle strength and to monitor …

To date, limited research has been conducted on hydration in surfers and no recommendations could be found regarding optimal hydration practices in surfers. This makes it difficult for dietitians and surf coaches to give evidence-based advice to surfers regarding optimal hydration practices. In order …

A program that automatically detects auroral events in all-sky images taken by the all-sky camera of IRF has been written. Current programs that automatically detect the aurora in all-sky images using the RGB color system often miss strong aurora and sometimes interprets clouds as aurora. To improve …

Reversed-phase HPLC with mass spectrometric and diode array detection as well as some literature data were used to reveal the individual types of solutes in anthocyanin complexes of tulip flower petals that are responsible for tulip flower petals coloration of the samples available in the local flower …

Objective: To determine content validity of the Muscle Power Sprint Test (MPST) and construct validity and reliability of the MPST, 10x5 Meter Sprint Test (10x5MST), slalom test and one stroke push test (1SPT) in wheelchair-using youth with spina bifida (SB). Design: Clinimetric study Setting: Rehabilitation …

In order to determine whether small-sided game (SSG) locomotor performance can serve as a fitness indicator, we (1) compared 6-a-side (6v6) SSG-intensity of players varying in fitness and skill, (2) examined the relationship of the 6v6-SSG and Yo-Yo IR2 and (3) assessed the reliability of the 6v6-SSG. …

The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. Four hundred sixty-three Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordinationstest …

The Department of Pathobiology of the Veterinary Faculty at the University of Utrecht is investigating the causes of the death of stranded porpoises. The causes of death of porpoises are assessed by internal and external investigation at the Utrecht University. At dissections, the organs of the dead …

Background: Body composition measurements provide importanti nformation about physical fitness and nutritional status. People with severe intellectual and visual disabilities (SIVD) have an increased risk for altered body composition. Bioelectrical impedance analysis (BIA) has been evidenced as a reliable …
