AI in Bundesliga match analysis—expected possession value (EPV) vs. expected goals (xG) to predict match outcomes in soccer
With an increasing number of key performance indicators (KPIs) in soccer analytics, it is key to identify the most valuable KPIs. One approach to define a KPI's value is to assess its ability to predict match outcomes and future performance. Therefore, this study aims to compare the effectiveness of expected goals (xG) and expected possession value (EPV) in predicting match outcomes in both pre-match and post-match scenarios. Event and tracking d…
Association between physical activity and physical health in German children and adolescents - results from the MoMo Longitudinal Study
Participating in sports regularly from adolescence to early adulthood is associated with the strongest health benefits. Nevertheless, those who were less active initially but increased their sports activity had similar health outcomes, highlighting the importance of sports activity as part of a healthy lifestyle in young adulthood
Association between neighborhood environment and self-reported and objectively measured physical activity in Hispanic families
Our findings may underscore the importance of neighborhood aesthetics and traffic safety for PA engagement in children. Longitudinal studies are needed to confirm our observations, and to untangle potential mechanisms linking neighborhood environment and PA in understudied populations such as Hispanics
Socio-structural determinants of physical activity behavior in children and adolescents
The purpose of this study is to analyze the influence of socio-structural determinants of physical activity (PA) behavior in children and adolescents. We expected that socioeconomic status, social support, and physical environment influence PA directly while socioeconomic status also has an indirect influence via social support and physical environment. Cross-sectional data from the German Motorik-Modul study (MoMo) were used (Wave 2, 2014-2017).…
Associations between green space availability and youth’s physical activity in urban and rural areas across Germany
Green space may be an important physical activity facilitator for children and adolescents. However, to date, most studies focused on urban green space, and few studies investigated associations between green space and physical activity across urban and rural areas, which was the goal of this study. Data were obtained from a German cohort study, including 1,211 youth aged 6–17 years. Residential green space was assessed within a 1000 m street-net…
Longitudinal association between fitness and metabolic syndrome
Fitness may be a predictor of longitudinal metabolic health, and potentially also mediates previously reported longitudinal associations between physical activity and metabolic health. More research is needed to confirm these observations, and to also explore underlying mechanisms

Purpose The aim of this study was to assess the concurrent validity of a contact mat against force plates to measure jump height in countermovement jump (CMJ) and squat jump (SJ) in professional soccer players. Methods 23 male professional soccer players performed the CMJ and SJ, which were concurrently recorded using a portable contact mat (SmartJump) and a portable dual force plate system (ForceDecks). Equivalence testing between both systems (…
App development in a sports science setting
The digital health sector is rapidly growing. With only 4% of publishers out of academic settings, it is under-represented in app development. The objective of this study is to assess the current state of app development with a systematic review and a survey within an exemplary academic setting along the following research questions: (Q1) Are software engineering principles sufficiently known in the sports science app development context? (Q2) Is…
A tool to assess fitness among adults in public health studies – Predictive validity of the FFB-Mot questionnaire
Our results suggest that the FFB-Mot to assess fitness in adults has predictive validity for health-related outcomes as indicated by significant correlations, albeit some effect sizes are small. The FFB-Mot may be used as one-time assessment of self-reported fitness, or for repeated testing to assess change of self-reported fitness over time and in different settings (e.g., public health research)
Analyzing mechanisms of interdisciplinary cooperation in promoting students’ health at university
The results of this study provide for a better understanding of the mechanisms of cooperation and can be used to further develop the network at hand (e.g. selection of key actors for information dissemination or integration of peripheral actors). In addition, the findings offer starting points for sustained network development at other universities (e.g. significance of network governance form or goal consensus). Knowing the factors that influenc…
Association between physical activity and longitudinal change in body mass index in middle-aged and older adults
PA, particularly at moderate-vigorous intensity, is associated with slower decline in longitudinal BMI trajectories. This implies that engaging in PA may be beneficial for healthy body weight regulation in middle and late adulthood

Urban-Rural Differences in Children’s and Adolescent’s Physical Activity and Screen-Time Trends Across 15 Years
BACKGROUND: Urban and rural areas have been experiencing major demographic and structural changes, characterized by an aging population in rural areas and a growth of cities in number and size. However, it is poorly researched how children's physical activity and screen time developed in urban and rural areas. To address this deficit, we investigated physical activity and screen-time trends in Germany's pediatric population across four urbanicity…
Physical Activity and Recurrent Pain in Children and Adolescents in Germany—Results from the MoMo Study
Recurrent pain can be a significant disruption in the activities of daily life, and is not only a health problem in adults but also in children and adolescents. This study analyzed the prevalence of recurrent pain in the current sample (n = 1516; 11-17 years (mean age = 14.4 ± 2.0 years); 50.8% female) of a nationwide study in Germany, evaluated the association of participants' device-based physical activity (PA) with the prevalence of recurrent …
A Study on the Psychometric Properties of the Short Version of the Physical Activity Enjoyment Scale in an Adult Population
A new measure of the short form of the Physical Activity Enjoyment Scale (PACES-S), including four items, has been developed that focuses on the subjective experience of enjoyment. As validation has so far only been conducted in a youth population, the purpose of the present article was to test the psychometric properties of the measure in an adult population in three studies. In the first study ( n = 1017) the results supported the unidimensiona…
Effects of Different Types of High-Intensity Interval Training (Hiit) on Endurance and Strength Parameters in Children and Adolescents
High-Intensity Interval Training (HIIT) promises high training effects on aerobic fitness in children, adolescents and adults in a relatively short time. It is therefore well-established in professional training settings. HIIT methods could also be suited to Physical Education (P.E.) lessons and contribute to students’ health and fitness. Since HIIT sessions need little time and equipment, they can be efficiently implemented in P.E. However, ther…
Community networks of sport and physical activity promotion
The study provided valid and robust findings on significant mechanisms and conditions of interorganizational cooperation in community networks focused on sport and physical activity promotion. Based on the results, implications for the development and most efficient governance of these networks can be derived
Changes of Self-Rated Health Status, Overweight and Physical Activity During Childhood and Adolescence—The Ratchet Effect of High Parental Socioeconomic Status
Childhood and adolescence are important life periods for the development of health status and physical activity (PA) behaviours. This study analyses the stability and potential changes of self-rated health status, overweight and PA behaviour over time, specifically focusing on the age and the socioeconomic status of children and adolescents. We employ representative longitudinal data for German children and adolescents from the Motorik-Modul Stud…
Promoting Students' Health at University
Background: Cooperation among university units is considered a cornerstone for the promotion of students' health. The underlying mechanisms of health-promoting networks at universities have rarely been examined so far. Shedding light on partnerships is generally limited to the naming of allied actors in a network. Objectives and Methods: In this study, we used network analysis intending to visualize and describe the positions and characteristics …
Association Between Sense of Coherence and Health Outcomes at 10 and 20 Years Follow-Up
Background: The sense of coherence (SOC) is reported to influence health, but health may also have an impact on SOC. The objective of this study was to examine the longitudinal associations between SOC and selected self-reported and physician-assessed health outcomes over a period of 10 and 20 years and to determine the predominant direction of the associations. Methods: We conducted a population-based, longitudinal study, involving 392 participa…

The Impact of Covid-19 on the Interrelation of Physical Activity, Screen Time and Health-Related Quality of Life in Children and Adolescents in Germany
Reduced physical activity (PA) and prolonged screen time (ST) negatively influence health-related quality of life (HRQoL), a protective factor against illness and mortality. Studies addressing the relationship between PA, ST, and mental health in youth are scarce, especially in times with high mental health burdens like the COVID-19 pandemic. The purpose of this examination was to investigate whether PA, ST, and HRQoL before COVID-19 predict PA, …
Standing Breaks in Lectures Improve University Students’ Self-Perceived Physical, Mental, and Cognitive Condition
While adolescents and adults should limit high levels of sedentary behavior, university students spend large amounts of time on sedentary activities. The aim of this study was to investigate the effect of this prolonged sitting on students' self-perceived physical, mental, and cognitive condition and to answer the question of whether simple standing breaks in lectures can help students improve these conditions and for example feel more concentrat…
A Short Version of the Physical Activity Enjoyment Scale
The results indicate that PACES-S is a reliable and valid instrument that may be particularly useful to measure physical activity enjoyment in large-scale studies. It shows comparable measurement properties as the long version of PACES
Social network analysis in sport research
While network analysis is a major methodological approach in many disciplines of the social and natural sciences, it has only recently come into the focus of sport researchers. This article assesses the utility of network analysis to analyze sport phenomena. We begin with an overview of social network analysis (SNA) and related concepts. To explore research topics and approaches, we conduct a systematic review of empirical literature of SNA and i…
Endurance Capacities in Professional Soccer Players
The aim of this study was to investigate position-specific endurance performance of soccer players. 136 professional players competing in the 1st and 2nd division in Germany were divided into the positional groups goalkeepers (GK), central defenders (CD), wingers (WI), central midfielders (CM), and forwards (FW). All players performed an incremental treadmill test with blood lactate sampling until exhaustion with the following endurance parameter…

Validity and reliability of a self-report instrument to assess social support and physical environmental correlates of physical activity in adolescents
The results of this study indicate moderate to good reliability and construct validity of the social support scale and physical environment scale. Predictive validity was only confirmed for the social support scale but not for the physical environment scale. Hence, it remains unclear if a person's physical environment has a direct or an indirect effect on physical activity behavior or a moderation function
Prevalence and socio-demographic correlates of the compliance with the physical activity guidelines in children and adolescents in Germany
Programs and policy action addressing the problem of decreasing compliance with PA guideline with increasing age are warranted. The transition from primary school to secondary school seems to be a critical stage in life with respect to PA behaviour. Therefore, specific interventions should aim at restructuring and reorganising their daily and physical activities during this transition
A cluster-analytic approach towards multidimensional health-related behaviors in adolescents
Meaningful and stable clusters of health-related behavior were identified. These results confirm findings of another youth study hence supporting the assumption that these clusters represent typical behavior patterns of adolescents. These results are particularly relevant for the characterization of target groups for primary prevention of lifestyle diseases
Long-term health benefits of physical activity – a systematic review of longitudinal studies
Distal and Proximal Factors of Health Behaviors and Their Associations with Health in Children and Adolescents
Several distal and proximal factors are needed to take account of the multivariate complexity of health: e.g., immigration background affected health behaviors only indirectly and the effect of physical activity on objective health was mediated by physical fitness
Tracking physical activity in different settings from late childhood to early adulthood in Germany
After publication of the article [1], it has been brought to our attention that the values cited under "indices t1-t0" have been reversed and should be displayed in the opposite order. The corrected Table 1 would appear as follows
Physical Activity of German Children and Adolescents 2003–2012
Organized and unorganized physical activity (PA) hold an important role in the daily life of children and adolescents. Regular representative tracking of PA in different settings is important to evaluate social trends and implemented interventions. In this paper, representative PA data of German children and adolescents from the MoMo Baseline-Study (2004, n = 4528) are compared to those of Wave 1 (2010, n = 3994). Participants aged 4-17 were draw…

Social Support and Modelling in Relation to Physical Activity Participation and Outdoor Play in Preschool Children
Physical activity during early childhood is a prerequisite for healthy development in many cases. The aim of this study was to assess the relationships of social modelling and support from parents, peers, and siblings and domain-specific physical activity participation in a nationwide sample of preschool boys and girls from Germany. 519 preschool children aged 4-6 and one of their parents participated in the 'MoMo' Wave 1 Study between 2009 and 2…
Exploratory Determined Correlates of Physical Activity in Children and Adolescents
Background : Physical activity is an important contributor to reducing the risk for a variety of diseases. Understanding why people are physically active contributes to evidence-based planning of public health interventions because successful actions will target factors known to be related to physical activity (PA). Therefore the aim of this study is to identify the most meaningful correlates of PA in children and adolescents using a large, repre…
Prevalence of Underweight and Overweight and Its Association with Physical Fitness in Egyptian Schoolchildren
Underweight and overweight are serious health concerns for many children and could be associated with low physical-fitness levels. This study aimed (i) to evaluate the prevalence of underweight and overweight and (ii) to examine its association with the physical fitness levels in primary male and female schoolchildren. Including 13 government primary-schools, a cross-sectional survey was conducted between 2014 and 2017. Anthropometric characteris…

Physical activity and screen time of children and adolescents before and during the Covid-19 lockdown in Germany
The impact of COVID-19 on social life has been drastic and global. However, the different numbers of cases and different actions in different countries have been leading to various interesting yet unexplored effects on human behavior. In the present study, we compare the physical activity and recreational screen time of a representative sample of 1711 4- to 17-year-olds before and during the strictest time of the first COVID-19 lockdown in German…
Representative Percentile Curves of Physical Fitness From Early Childhood to Early Adulthood
Introduction: The aim of this analysis is to report sex- and age-specific physical fitness percentile curves from childhood to early adulthood in a nationwide sample in Germany. Already in childhood, physical fitness is considered as one of the most important health markers. From a developmental and preventive perspective, physical fitness levels are relatively stable from childhood to early adulthood. Thus, it is important to monitor physical fi…
