OBJECTIVE To evaluate the health-related content validity of nine fitness tests by studying how low, mid, and high levels of fitness are associated with perceived health and musculoskeletal functioning. DESIGN Cross-sectional methodological study. SETTING A research institute for health promotion. PARTICIPANTS Middle-aged (37 to 57 years) men (n =(More)
AIM Identifying factors that influence children's and adolescents' participation in physical activity (PA), as well as their physical fitness (PF), is essential for the development of effective intervention strategies. The aim of this study was to investigate and compare influential socio-demographic factors that affect PA such as socio-economic status(More)
This study investigated whether a 21.1 km (half-marathon) or a 42.195 km (marathon) run modulates DNA damage, antioxidant capacity in lymphocytes and plasma, and the immune system in healthy hobby runners. Ten and 12 volunteers who completed the Baden-Marathon race in Karlsruhe with a running distance of 21.1 km and 41.195 km, respectively, were assessed 10(More)
The aim of this study was to gain insights into the relationship between developmental coordination disorder, peer problems, and behavioral problems in school-aged children where both internalizing and externalizing behavioral problems were considered. We assumed that the relationship between developmental coordination disorder and(More)
Acute and regular exercise as well as physical activity (PA) is related to well-being and positive affect. Recent studies have shown that even daily, unstructured physical activities increase positive affect. However, the attempt to achieve adherence to PA or exercise in inactive people through public health interventions has often been unsuccessful. Most(More)
OBJECTIVES The aim of the 'Motorik-Modul' (MoMo Basiserhebung, www.motorik-modul.de ) was to establish prevalence measurements on physical fitness and physical activity in German children and adolescents and to identify differences between age groups and genders. A total of 4,529 children and adolescents between the ages of 4-17 years from 167 cities across(More)
Physical fitness can serve as a means to enhance cognitive functioning by modulating particular aspects of brain functioning. However, mechanisms underlying this modulating effect remain widely unresolved. To examine the impact and to clarify the mechanisms of physical fitness training in a young and healthy population, it was investigated whether an(More)
OBJECTIVE In two studies, the reliability of 3 balance, 2 flexibility, and 4 muscular strength tests proposed as test items were investigated in a health-related fitness (HRF) test battery for adults. DESIGN Methodological study. SETTING A health promotion research institute. SUBJECTS In study A, volunteers (n=42) from two worksites participated. In(More)
The Motorik-Modul (MoMo) Longitudinal Study aims to contribute to long-term improvement in the health of German children and adolescents by focusing on: (i) the development of physical fitness and physical activity (including period effects); (ii) the individual and physical/social environmental determinants of the development of physical fitness and(More)
This study aimed to determine the effects of a single high-intensity interval training (HIIT) session on salivary cortisol (SC) levels, physiological responses, and performance in trained boys and men. Twenty-three boys (11.5 ± 0.8 years) and 25 men (29.7 ± 4.6 years) performed HIIT (4 consecutive Wingate Anaerobic Tests). SC in boys and men increased after(More)
