Mental health (MH) and behavioral health are fundamental to a good quality of life. Only a few studies have investigated the association between behavioral health (e.g. physical activity (PA), screen time (ST)) and MH from childhood to adolescence. Therefore, we investigated the relationships of PA and ST with MH by sex in an 11-year longitudinal cohort study of German schoolchildren during 2003–2017. A subsample (n  = 686; 55.2% female) of participants from the German Motorik-Modul (MoMo) Longitudinal Study who participated in all 3 measurement phases (mean ages: time 1 (baseline; 2003–2006), 5.57 (standard deviation (SD), 1.00) years; time 2 (wave 1; 2009–2012), 11.85 (SD, 1.03) years; time 3 (wave 2; 2014–2017), 16.86 (SD, 1.04) years) were analyzed with regard to PA, ST, and MH (emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship problems, prosocial behavior, and overall strengths and difficulties). Path panel prediction models were fitted with time 1, time 2, and time 3 PA, ST, and MH indicators. PA predicted less television (TV)/video watching in females, and TV/video watching predicted personal computer (PC)/Internet use in both sexes. Behavior and MH results suggested that, for females, higher TV/video watching and PC/Internet use was related to higher MH challenges over the course of maturation. Some preadolescent males' MH challenges increased ST (TV/video watching and PC/Internet use) in adolescence. Researchers should explore innovative and effective methods for reducing childhood ST, especially among females with early signs of MH issues, and addressing preadolescent males' MH challenges.

Background: Fitness has important implications for physical activity behavior and is associated with various health-related outcomes. It can be assessed through a test battery or a self-reported questionnaire. One example is the FFB-Mot (Funktionsfragebogen Motorik; engl. functional fitness questionnaire) which consist of 28 items to assess four components of fitness in adults: cardiorespiratory fitness/ endurance, muscular strength, gross motor coordination, and flexibility. The aims of this manuscript were to (1) provide an English-version of the FFB-Mot questionnaire (developed from the German-version using translation and back-translation) to the international community of researchers in the areas of physical activity, fitness and health in adults, and (2) examine the predictive validity of the FFB-Mot questionnaire in a large sample of community-dwelling adults. Methods: We used data from a longitudinal study in Germany with four measurement waves over a period of 18 years, with samples ranging between 310 and 437 participants (1572 adults in total, mean ages 46–58 years). To assess predictive validity, we calculated Pearson correlations between FFB-Mot data collected in 1997 and external health-related criteria (i.e., subjective health status, physician-rated health status, back pain, physical complaints and physical activity in minutes per week) collected in 2002, 2010, and 2015, and separately for males and females. Results: We observed correlations between higher FFB-Mot scores with better subjective health status (in 2002: males, r = 0.25; females, r = 0.18; in 2010: males, r = 0.29; females, r = 0.28; in 2015: males, r = 0.40), and higher physical activity (in 2002: males, r = 0.24; females, r = 0.25; in 2010: males, r = 0.30; females, r = 0.38; in 2015: females, r = 0.27). Higher FFB-Mot scores were also correlated with lower back pain (in 2002: males, r = -0.23; females, r = -0.25; in 2010: females, r = -0.22), less physical complaints (in 2002: males, r = -0.36; females, r = -0.24), and better physician-rated health status (in 2002: males, r = -0.41; females, r = -0.29, 2010: males, r = -0.38; females, r = -0.44; in 2015: males, r = -0.47). Conclusions: 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).

Enjoyment is recognized as a determinant of physical activity habits. The enjoyment of engaging in physical activity can be measured with the Physical Activity Enjoyment Scale (PACES). Later versions of this scale have been shortened to capture the component of subjective feeling, which has been validated using German-speaking samples. The aim of this study was to examine internal consistency, factorial validity, criterion-related validity, test-retest reliability, and measurement invariance (across gender and languages) in an English-speaking population. Data on physical activity enjoyment and self-reported physical activity were collected through an online survey with a test-retest design (n = 276,189 female, M = 42.55, SD = 16.81 years) conducted from September 2023 to December 2023. In addition, a German-speaking sample (n = 1017, 497 female, M = 29.77, SD = 13.54 years) was analyzed to assess measurement invariance with respect to language. McDonald's omega at time 1 was ω = 0.95. The confirmatory factor analysis supports the assumption of the unidimensional structure of PACES-S (χ2 = 19.8, df = 2, p < 0.05; CFI = 0.984; RMSEA = 0.180, 90% CI [0.113–0.256]), as the model fit can be estimated as good in view of the CFI value, while the sensitivity of the χ2 test is very high and the RMSEA may underestimate the model fit. Although the RMSEA value is higher than the conventional threshold, the small number of degrees of freedom may have a significant impact on this indicator. The criterion-related validity for light physical activity was r(107) = 0.26 (p < 0.05). The retest reliability was r(199) = 0.69 (p < 0.05). Further, the results supported measurement invariance across gender and partial measurement invariance across languages. Overall, the English PACES-S demonstrated good psychometric properties specifically for light intensity of physical activity, and can serve as an economical instrument to assess physical activity enjoyment.

The purpose of the present study was to assess whether the recognition of tennis players' affective state associated with their nonverbal behavior would be influenced by (a) the importance of the situation, (b) the point outcome, and (c) the tennis expertise of the observer. Two hundred sixty-nine participants (Mage = 30.51 years; 116 female; 79 tennis club members) watched video excerpts showing the nonverbal behavior of amateur tennis players during competitive matches immediately after the end of a rally and were asked to estimate whether the player had just won or lost the point. Results indicate that the recognition rates were higher for situations closer to the end of a game, closer to the end of a set, and with a tighter score during a game. Moreover, recognition rates were higher for lost than for won points, while the tennis expertise of participants had no influence on the recognition rates. [ABSTRACT FROM AUTHOR]

In the present paper, we introduce a new theoretical model of self-regulation of physical activity. In particular, our model focusses on the explanation and identification of predictors of physical activity adoption and maintenance (PAAM model). Based on dual-process theories of self-regulation we postulate explicit (i.e., reflective, deliberate) and implicit (i.e., affective, automatic) processes to explain adoption and maintenance of physical activity behavior. Explicit processes include intention, trait self-regulation and executive functions while implicit processes combine affective processes and habit formation. These processes not only have direct effects on physical activity adoption and maintenance, but also have moderating and interacting effects. Future work should test these predictions empirically for physical activity and other health-related behaviors. [ABSTRACT FROM AUTHOR]

While the tactical behavior of soccer players differs between specific phases of play (offense, defense, offensive transition, defensive transition), little is known about successful behavior of players during defensive transition (switching behavior from offense to defense). Therefore, this study aims to analyze the group tactic of rest defense (despite in ball possession, certain players safeguard quick counterattacks in case of ball loss) in defensive transition. A mixed-methods approach was used, involving both qualitative and quantitative analysis. Semi-structured expert interviews with seven professional soccer coaches were conducted to define rest defense. In the quantitative analysis, several KPIs were calculated, based on tracking and event data of 153 games of the 2020/21 German Bundesliga season, to predict the success of rest defense situations in a machine learning approach. The qualitative interviews indicated that rest defense can be defined as the positioning of the deepest defenders during ball possession to prevent an opposing counterattack after a ball loss. For instance, the rest defending players created a numerical superiority of 1.69 ± 1.00 and allowed a space control of the attacking team of 11.51 ± 9.82 [%] in the area of rest defense. The final machine learning model showed satisfactory prediction performance of the success of rest defense (Accuracy: 0.97, Precision: 0.73, f1-Score: 0.64, AUC: 0.60). Analysis of the individual KPIs revealed insights into successful behavior of players in rest defense, including controlling deep spaces and dangerous counterattackers. The study concludes regaining possession as fast as possible after a ball loss is the most important success factor in defensive transition. [ABSTRACT FROM AUTHOR]

Physical activity intentions do not automatically lead to physical activity behavior, indicating that there are other (psychological) factors involved. In the present study, we tested the assumption that self-control strength is required to bridge the intention-behavior gap in terms of initial and weekly intentions. A total of N = 259 individuals, who registered for a weekly university sports course, were followed for 13 weeks. At baseline, trait self-control strength as well as the intention to take part in the respective sports course on a regular basis were measured. Then, we registered weekly participation and asked the participants after each training session to report their intention to show up at next week's training session. Despite very high baseline as well as weekly exercise intentions, the participation rate dropped considerably over time, indicating a large intention-behavior gap. The association of within-person fluctuations in weekly intentions and actual participation was moderated by self-control: Only in individuals with high levels of trait self-control strength stronger intentions were associated with a higher chance of actual re-attendance. Baseline intention was also associated with participation but not moderated by self-control. These findings indicate that high levels of self-control strength are beneficial in order to translate short-term intentions into actual behavior. Practical implications on how to improve self-control are discussed. • 259 participants in university exercise courses were followed for 13 weeks. • Course participation declined significantly over 3 months despite high intentions. • Initial and weekly exercise intentions predicted course participation. • High Self-control promotes the enactment of short-term exercise intentions. • Weekly fluctuations in intentions are more important than absolute intention levels.

Background: This quasi-experimental study aimed to compare the effectiveness of a digital prevention intervention on work ability, physical health, and mental health with a conventional prevention program for employees with initial impairments. The study recruited 245 participants, of whom 173 completed the study, 98 (65 female, 66.3%) in the intervention group and 75 (55 female, 73.3%) in the control group. Both groups received prevention programs, with the intervention group using the Caspar digital platform and the control group using the conventional BETSI/RV Fit program. There were three measurement points in the study: T0 before the intervention, T1 in the middle of the intervention, and T2 at the end of the intervention. Participants' health was assessed using the SF-12 health status questionnaire, while their work ability was measured using the short version of the Work Ability Index. Results: Repeated-measures analyses of variance indicated that both prevention programs were effective in improving work ability and mental health, while physical health did not show any significant improvement. Additionally, the results of the study suggest that younger individuals benefited more from the digital prevention intervention, while older individuals benefited more from the conventional prevention program. Conclusion: The study emphasizes the need for further research and improvements in both research and practice. Future studies should include larger sample sizes, randomized controlled trials, and follow-up assessments to enhance understanding of the effectiveness and the durability of effects of prevention programs.

Background: We examined the longitudinal association between (change in) physical activity (PA) with new onset of five risk factors of metabolic syndrome among 657 middle-aged adults (mean age 44.1 (standard deviation (SD) 8.6) years) who were free of the respective outcome at baseline, in a longitudinal cohort study spanning over 29 years. Methods: Levels of habitual PA and sports-related PA were assessed by a self-reported questionnaire. Incident elevated waist circumference (WC), elevated triglycerides (TG), reduced high-density lipoprotein cholesterols (HDL), elevated blood pressure (BP), and elevated blood-glucose (BG) were assessed by physicians and by self-reported questionnaires. We calculated Cox proportional hazard ratio regressions and 95% confidence intervals. Results: Over time, participants developed (cases of incident risk factor; mean (SD) follow-up time) elevated WC (234 cases; 12.3 (8.2) years), elevated TG (292 cases; 11.1 (7.8) years), reduced HDL (139 cases; 12.4 (8.1) years), elevated BP (185 cases; 11.4 (7.5) years), or elevated BG (47 cases; 14.2 (8.5) years). For PA variables at baseline, risk reductions ranging between 37 and 42% for reduced HDL levels were detected. Furthermore, higher levels of PA (≥ 16.6 METh per week) were associated with a 49% elevated risk for incident elevated BP. Participants who increased PA levels over time, had risk reductions ranging between 38 and 57% for elevated WC, elevated TG and reduced HDL. Participants with stable high amounts of PA from baseline to follow-up had risk reductions ranging between 45 and 87% for incident reduced HDL and elevated BG. Conclusions: PA at baseline, starting PA engagement, maintaining and increasing PA level over time are associated with favorable metabolic health outcomes. [ABSTRACT FROM AUTHOR]

The dichotomous classification of self-talk statements into goal-directed as a more controlled type of self-talk and spontaneous as a more uncontrolled type of self-talk might be an oversimplification. To address this issue, two studies were conducted aiming to explore the idea that the distinction between the two self-talk types should rather be proportional and not mutually exclusive. In Study 1, football players took part in a penalty competition and were subsequently asked to state the self-talk they had before and after the penalty. In Study 2, table tennis players took part in two activities (i.e., a precision task and a competitive set) and were subsequently asked to state the self-talk they had before the individual rounds in each activity. In both studies, the players subsequently rated for each self-talk statement the extent to which it was spontaneous and the extent to which it was goal-directed. The majority of self-talk statements were rated to some extent as both spontaneous and goal-directed. For Study 1, paired-sample t-tests showed that before a penalty kick self-talk was more goal-directed than spontaneous and after the penalty kick it was more spontaneous than goal-directed. In the more exploratory Study 2, multilevel regression analyses showed that the two types of self-talk could not predict sports performance. While the results support the usefulness of the distinction between spontaneous and goal-directed self-talk, treating the two types of self-talk as proportional rather than dichotomous might reflect more accurately the mental activity. Key words: dual-process, organic self-talk, self-regulation, System 1, System 2 • Use of a proportional classification of spontaneous and goal-directed self-talk. • Before a penalty, players reported higher extent of goal-directed self-talk. • After a penalty, players reported higher extent of spontaneous self-talk. • Self-talk did not predict performance in two activities in table tennis.

Objective: The authors assessed whether an intervention using motivational signs designed in a participatory manner to promote stair use resulted in changes to the proportion of stair to elevator use. Participants: Students of a German university were observed in three different academic buildings. Methods: The study design consisted of direct observations during a pre-intervention period, an intervention phase introducing motivational signs promoting stair use at points of decision and a post-intervention period. Results: The proportion of students who took the stairs on average differed significantly between baseline and intervention phase I (χ2(1) = 12.2; p =.001; Phi = 0.078), baseline and intervention phase II (χ2(1) = 17.3; p =.001; Phi = 0.093), and baseline and post-intervention (χ2(1) = 9.9; p =.002; Phi = 0.074). Conclusions: Simple and cost-effective interventions can increase stair use of university students. [ABSTRACT FROM AUTHOR]

We examined the longitudinal association between physical activity (PA) and the risk of incident metabolic syndrome (MetS) among middle-aged, community-dwelling adults, including 591 individuals (314 females; mean (SD) age, 43.8 (8.5) years) who were free of MetS at baseline. Habitual and sports-related PA was assessed by a self-reported questionnaire. MetS was defined based on HDL-cholesterols, triglycerides, glucose or HbA1c, blood pressure, and waist circumference. We calculated Cox proportional hazard ratios (HR) and 95% confidence intervals (CI) using regression analyses. Over a mean follow-up of 12.5 years, 205 participants developed incident MetS. Four different sports-related PA measures were associated with a decreased risk of incident MetS: (1) Engaging in ≥ 75 min/week (HR 0.71, 95% CI 0.53–0.94), (2) maintaining a continuously high amount from baseline to follow-up of ≥ 75 min/week (HR 0.66, 95% CI 0.46–0.94), (3) starting from < 150 min/week at baseline to ≥ 150 min/week at follow-up (HR 0.65, 95% CI 0.45–0.94), and (4) increasing from < 16.6 MET-hours/week at baseline to ≥ 16.6 MET-hours/week at follow-up (HR 0.47, 95% CI 0.31–0.71). Thus, maintaining, starting or increasing sports-related PA is associated with a lower risk of incident MetS. [ABSTRACT FROM AUTHOR]

Background: Physical activity (PA) has beneficial effects on health and health-related quality of life (HRQoL), which is a protective factor of illness and mortality. The purpose of this examination was to investigate if self-reported and device-based measures of PA were related to HRQoL in adolescents.Methods: Participants (N = 1565; 54.3% female; Mage = 14.37 years, SDage = 1.99) were recruited from 167 sample points across Germany. Adolescents self-reported their PA, supplemented by a 1-week examination of device-based PA using accelerometry. Additionally, they completed the multidimensional KIDSCREEN-27 to assess HRQoL.Results: Results showed that self-reported PA was correlated with overall HRQoL, Physical Well-Being, Psychological Well-Being, Social Support & Peers, and School Environment, whereas device-based PA was only correlated with Physical as well as Psychological Well-Being. Further, self-reported PA significantly predicted all facets of HRQoL except for Autonomy and Parent Relations, whereas device-based PA solely heightened the amount of explained variance in the Physical Well-Being subscale.Conclusions: Findings demonstrate the importance of self-reported PA as it is related to almost all facets of HRQoL. Both measures of PA are not congruent in their relationship with HRQoL and thus implications have to be carefully considered. Future studies should investigate the direct effect of PA on HRQoL and health in a longitudinal approach to account for the causality of effects. [ABSTRACT FROM AUTHOR]
