Endurance performance tests directly measuring cardiorespiratory fitness are complex, but field tests indirectly assessing maximum oxygen uptake (VO) are an alternative. This study aimed to validate the 6-minute run test in adults, comparing it to the established shuttle run test, and to create reference equations. The cross-over design involved healthy adults aged 18-65 undertaking both tests, separated by a two-hour interval.

The concept of physical literacy (PL) is a promising holistic approach to physical activity promotion that addresses affective and cognitive domains in addition to physical and motor domains. In Germany, however, no uniform or widely used method exists for assessing PL in children.

The objective is to identify predictors of changes in body mass index standard deviation scores (BMI-SDS), so as to further enable the advancement of existing interventions with sustained impact. This study's sample consists of 237 children and adolescents with obesity (8-17 years, 54% girls) participating in the CHILT III program between 2003 and 2021.

Given the continued prevalence of obesity, we examined the secular trend of body mass index standard deviation score (BMI-SDS) and self-concept in participants of a German weight management programme ( = 242, 53.3% female, mean age 12.

We developed an assessment tool to measure and evaluate the promotion of individual PL and its four subdomains: motivation and confidence (the affective dimension), physical competence (physical dimension), knowledge and understanding (cognitive dimension), and participation in physical activity. Within this cross-sectional study, we tested 567 children aged 6−12 years from four primary schools that differed in socioeconomic status (SES).

Additionally, a decrease in motor performance has been increasingly reported; however, there is a lack of meaningful data on the relationship between these findings and socioeconomic status. Therefore, we examined the BMI, BMI score, the prevalence of overweight/obesity, and motor performance (based on lateral jumping, the standing long jump, and the 6-min run) among three cohorts from timelines before (2016) and during the pandemic (2020, 2021), using a cohort sequential design.

In the pathogenesis of insulin-resistance-related diseases, including obesity and diabetes, Vitamin D deficiency is very common. Therefore, the relationship between insulin resistance, body composition, vitamin D level, and cardiorespiratory fitness in obese children and youth were analyzed based on the Children's Health InterventionaL Trial III project, Germany.

Therefore, we studied the prevalence of sarcopenia and its association with cardiometabolic risk factors as well as muscular and cardiorespiratory fitness using data from the German Children's Health InterventionaL Trial (CHILT III) programme. In addition to anthropometric data and blood pressure, muscle and fat mass were determined with bioelectrical impedance analysis.
