External funding increases as the number of quality proposals submitted increases; increasing the number of faculty submitting proposals is a logical step to increase external funding. Reflecting on a physical educator’s > $1.5 million grant portfolio, two main themes emerge: the role of the PI and the unit administrator. Realizing increases in external funding is in part a result of administrators empowering faculty for success, and five administrator strategies have been identified. These strategies include: (1) value all sources of external funding (e.g., teaching, research, outreach, federal, foundation), (2) reward the process and the outcomes (a good proposal is equal to a data-based paper), (3) facilitate connections for collaboration (e.g., spread the word about your faculty), (4) provide infrastructure (from labs to personnel evaluation), (5) identify and develop potential. Important strategies for PIs include: (1) write proposals, (2) take risks, (3) answer the phone, (4) details matter, and (5) seek collaborators.

Increasing physical activity among children and adolescents continues to be a public health priority (Glickman et al., 2012), with a focus on evidence-based physical activity in school settings. While individual studies report benefits from school-based physical activity interventions, no data-based analysis of these interventions has been published. This meta-analysis examined the outcomes of 12 school-based interventions that reported data from both treatment and intervention groups. The design of each study was unique; including one or more of 19 dependent variables representing physical activity, knowledge, body composition, and cardiovascular measures, and one or more component of the Coordinated School Health Model (CSHM). Generally the benefits from the intervention were small and not significant; health knowledge was the exception. Interventions including more components of the CSHM and interventions of greater duration (e.g., more minutes) were associated with enhanced outcomes and explained 89% of the variance. Weaknesses in the design and analysis of some interventions were inappropriate experimental unit (individual rather than school), multiple analyses on the same data without correction (e.g., Bonferroni), multiple publications of the same data, and the inclusion of all students regardless of whether the student needed to increase physical activity/ftness or reduce body mass/fat.

The purpose of this study was to investigate the associations among predisposing (perceived competence and enjoyment), reinforcing (social environments), enabling factors (motor skills, fitness, physical environments) and physical activity among 288 children, and to identify the age and gender differences among participants. The children completed previously validated questionnaires assessing their perceived competence, enjoyment, school social and physical environments, and physical activity. Physical fitness was measured by FITNESSGRAM fitness testing. Students’ motor skills were assessed by PE Metrics. The results indicated that perceived competence and enjoyment predicted physical activity for boys, while perceived competence was the only predictor for girls. Age effects for fitness and skill were significant, as were gender differences for skill, social environment and perceived competence. This study suggests the importance of supportive teachers who provide enjoyable physical education that builds perceived competence for children to improve fitness, motor skill development and physical activity participation. The results support associations between predisposing factors and self-reported physical activity as theorized within the social ecological model.

Purpose: Based on the self-determination theory, this study explored the predictive strengths and relative importance of basic psychological needs (BPNs; i.e., autonomy, competence, and relatedness) in physical education in physical, cognitive, and psychological outcomes among Hispanic boys and girls. Methods: Fourth- and fifth-grade Hispanic children (N = 214; 110 boys and 104 girls) completed surveys measuring BPNs, effort in physical education, and general well-being and objective assessments of cardiorespiratory fitness and body mass index. Multiple regression analyses were performed on the three adaptive outcomes by gender to determine the relative importance of BPNs. Results: The analyses revealed that (a) competence was the most important BPN in predicting effort and well-being among both boys and girls; (b) relatedness predicted only well-being among boys, but both effort and well-being among girls; and (c) autonomy did not predict any outcomes. Conclusions: The findings highlight the importance of satisfying Hispanic children’s competence and girls’ relatedness in physical education.

This study examines the associations of physical activity and gross motor skills in parent–child dyads. Parent–child dyads (N = 61, 84% mothers, children aged 8–11 years) participated in this study. Anthropometrics were self-reported through Qualtrics. Physical activity was assessed using accelerometers. Motor skills were measured through four skills: catch, kick, throw, and jump. These skills were assessed using process (i.e., performance criteria of the Test of Gross Motor Development-3) and product (i.e., catch percentage and jump distance) measures. A complete motor skill score was computed by standardizing both process and product scores and summing them. Correlation coefficients and ordinary least square regressions were computed to examine the associations of physical activity and motor skills. Parents’ and children’s moderate to vigorous physical activity were significantly associated (β = 0.30 ± 0.11; p = .008). Parents’ and children’s motor skills were significantly associated (β = 0.46 ± 0.18; p = .012). Understanding parent determinants can support effective interventions targeting children’s low physical activity levels and improving motor competence. Our results highlight the importance of parents’ physical activity and motor skills, which are significantly associated with those of their children. These parent factors may be a key consideration for effective family-based physical activity interventions.

Sit-to-stand transfer is a common task that is challenging for older adults and others with musculoskeletal impairments. Associated joint torques and muscle activations have been analyzed two-dimensionally, neglecting possible three-dimensional (3D) compensatory movements in those who struggle with sit-to-stand transfer. Furthermore, how muscles accelerate an individual up and off the chair remains unclear; such knowledge could inform rehabilitation strategies. We examined muscle forces, muscleinduced accelerations, and interlimb muscle force differences during sit-to-stand transfer in young, healthy adults. Dynamic simulations were created using a custom 3D musculoskeletal model; static optimization and induced acceleration analysis were used to determine muscle forces and their induced accelerations, respectively. The gluteus maximus generated the largest force (2009.07 ± 277.31 N) and was a main contributor to forward acceleration of the center of mass (COM) (0.62 ± 0.18 m/s²), while the quadriceps opposed it. The soleus was a main contributor to upward (2.56 ± 0.74 m/s²) and forward acceleration of the COM (0.62 ± 0.33 m/s²). Interlimb muscle force differences were observed, demonstrating lower limb symmetry cannot be assumed during this task, even in healthy adults. These findings establish a baseline from which deficits and compensatory strategies in relevant populations (eg, elderly, osteoarthritis) can be identified.

Background: A combination of walking, other moderate physical activity, and vigorous physical activity is recommended for achieving good health. Vigorous activity has unique health benefits but may be less accessible to disadvantaged people. To reduce health inequity, we need to understand the differences in physical activity participation among socioeconomic subgroups and whether this is changing over time. Methods: Data from the 2002 to 2015 Adult New South Wales Population Health Surveys (164,652 responses) were analyzed to investigate trends in walking, moderate and vigorous physical activity participation by socioeconomic status as measured by educational attainment. Analysis used age- and sex-adjusted multivariable linear models that accounted for complex survey design. Results: In 2002, the highest socioeconomic group spent 18.5 (95% confidence interval, 8.2–28.8) minutes per week more than the lowest socioeconomic group being vigorously active. By 2015, this gap had steadily increased to 41.4 (95% confidence interval, 27.6–55.1) minutes per week. Inequity between groups was also found for duration of moderate activity but not for time spent walking. Conclusions: Low participation in vigorous activity in the lowest socioeconomic group is likely driving increasing inequities in physical activity and widening participation gaps over time. Barriers preventing the most disadvantaged people in New South Wales from engaging in vigorous activity should be addressed urgently.

The study objective was to determine the magnitude and frequency of head impacts in NCAA Division III soccer athletes based on player position and type of play (offense, defense, transition). Across player position, male and female soccer defenders sustained the most head impacts (males IR = 18.89, 95% CI = 16.89–20.89; females IR = 8.45, 95% CI = 7.25–9.64; IRR = 2.23, 95% CI = 1.87–2.67). The study revealed a nonstatistically significant interaction between sex, player position, and type of play for both linear (p = .42) and rotational accelerations (p = .16). Defenders sustained the majority of the head impacts in the study sample, suggesting preventative initiatives should be focused on back row players.
