Motorik-Modul Study

About MoMo

Background of the Study

Research has shown that motor performance and physical activity levels in children and adolescents has declined over the past decades. This may also have an impact on both physical and mental health and well-being. However, to date, little is known about the magnitude of decline in motor performance and physical activity status. This is partly due to a lack of high-quality longitudinal data derived from representative study samples.

The Motorik-Modul Study (MoMo) is the first population-based study in Germany to examine the longitudinal associations between motor performance, anthropometric measures such as body composition and physical activity levels in a representative sample of children, adolescents and young adults. Since 2015 (until 2021) the principal investigators of MoMo are Professor Dr. Alexander Woll of the Karlsruhe Institute of Technology and Professor Dr. Annette Worth of the University of Education Karlsruhe in cooperation with the Robert Koch-Institute in Berlin. 


The overarching aim of the study is to contribute to the assessment and improvement of long-term health among children, adolescents and young adults in Germany. The study addresses various research questions along the lines of motor performance, physical activity and health, such as:

  • Do active and fit children and adolescents turn into active and fit adults?
  • Does physical activity have an impact on chronic diseases?

For this purpose, the following aspects are investigated:

  1. The effects of internal (e.g., personal attitudes, age, sex) and external factors (e.g., influence of peers/peer-group, parents, socioeconomic level, environment like urban/rural or migration background) on the development of physical activity in early and late adolescence.
  2. The effects of physical activity (type, intensity, duration, frequency), internal (age, sex) and external factors (socio-economic level, environment, migration background) exerting an influence on the change/development of physical fitness.
  3. The effects of physical fitness and physical activity as predictors of physical health (e.g., pain, obesity), biochemical risk factors, overall health and how they affect mental health and quality of life.
  4. The age-related and period effects on physical activity and physical fitness in childhood and adolescence.


The Motorik-Modul Study (MoMo) is funded by the Federal Ministry of Education and Research within the program "long-term studies" in public health research (funding reference number: 01ER1503).
