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 physical activity; and (iii) the impact of physical fitness and physical activity on the development of physical and mental health. The MoMo Longitudinal Study began with a nationwide representative sample of 4529 children and adolescents who ranged in age from 4-17 years at the study baseline (2003-2006). The first survey wave of the MoMo Longitudinal Study was conducted between 2009 and 2012, with two subsequent survey waves to be conducted between 2014 and 2016 and 2018 and 2020, respectively. The MoMo Longitudinal Study includes a physical fitness test profile, a physical activity questionnaire, and subjective and objective measures of health from the German Health Interview and Examination Survey (KiGGS).

Motor fitness was investigated in children and adolescents aged 4-17 using specific short tests. These tested the motor abilities: co-ordination, strength, cardiorespiratory fitness and flexibility. Among the 4-10 year olds, the focus of the investigation was on recording coordination, strength and flexibility; in the age group of the 11-17 year olds it was on recording cardiorespiratory fitness. The current investigation describes motor fitness based on the tested abilities according to age, sex and sociodemographic aspects. In all the test tasks, as expected, there are better results from older children and adolescents than from younger ones. Among the 4-10 year olds, girls display a slightly higher motor fitness in five out of the six tasks. In cardiorespiratory fitness, the cycle ergometer test for the 11-17 year olds shows better results for boys. The results indicate that there is a correlation between migrant status, social status and motor fitness. The shown differences point out that possible intervention programmes should be specifically attuned to age and sex as well as to the concerns of children and families with a migrant background and those of low social status. These collected data on motor fitness produced a database, representative of Germany. This will enable statements on state and development of motor fitness in children and adolescents in the future.

LeitthemaUm Fehlentwicklungen im Bewegungsverhalten frühzeitig detektieren zu können, sind regelmäßige, möglichst standardisierte Untersuchungen erforderlich. Im Rahmen des Motorik-Moduls (MoMo) wurde eine Testbatterie entwickelt, anhand derer der motorische Leistungsstand von Kindern quantifiziert und kontrolliert werden kann. Es wird auf die Bedeutung sportmotorischer Tests in der Kinderarztpraxis eingegangen, indem erläutert wird, was unter motorischer Leistungsfähigkeit zu verstehen ist und welche allgemeinen Ziele mit ihrer Diagnose verbunden sind. Darüber hinaus werden ausgewähl-te sportmotorische Tests der MoMoTestbatterie vorgestellt und ihre Einsatzmöglichkeiten in der Kinderarztpraxis diskutiert.
