Abstract: The skeleton of a cricket fast bowler is exposed to a unique combination of gravitational and torsional loading in the form of substantial ground reaction forces delivered through the front landing foot, and anterior-posterior shear forces mediated by regional muscle contractions across the lumbo-pelvic region. The objectives of this study were to compare the hip structural characteristics of elite fast bowlers with recreationally active age-matched controls, and to examine unilateral bone properties in fast bowlers. Dual-energy X-ray absorptiometry of the proximal femur was performed in 26 elite male fast bowlers and 26 normally active controls. Hip structural analysis (GE Lunar enCORE version 15.0) determined areal bone mineral density (BMD) of the proximal femur, and cross-sectional area, section modulus (Z), cross-sectional moment of inertia, and femoral strength index at the narrow region of the femoral neck. Mean femoral neck and trochanter BMD were greater in fast bowlers than in controls (p <0.001). All bone geometry properties, except for cross-sectional moment of inertia, were superior in fast bowlers (p 0.05). Elite fast bowlers have superior bone characteristics of the proximal femur, with results inferring enhanced resistance to axial compression (cross-sectional area), and bending (Z) forces, and enhanced strength to withstand a fall impact as indicated by their higher femoral strength index. No asymmetries in hip bone properties were identified, suggesting that both torsional and gravitational loading offer significant osteogenic potential.

Abstract: This study investigated the physical activity experiences of people living with and beyond cancer (PLWBC) during the COVID-19 pandemic. Participants attended the cancer and rehabilitation exercise (CARE) programme delivered by a football community trust. Staff (n = 2) and participants (n = 9) attended semi-structured interviews investigating the PA participation and experiences of attending/delivering different modes of CARE, including exercise classes delivered outdoors and delivered online. Interviews also investigated participant aspirations for returning to CARE sessions delivered in person indoors. The findings show that the COVID-19 pandemic and government restrictions impacted on PA participation, yet exercise sessions provided via CARE offered participants an important opportunity to arrest their inactivity, keep active and maintain their fitness and functionality. Barriers to participation of CARE online included access to IT infrastructure, internet connectivity and IT skills and comfort using IT. Regarding CARE outdoors, the weather, range of equipment, variety of exercises and the lack of toilets and seats were barriers. In the different CARE modes, the skills of delivery staff who were sensitive to the needs of participants, social support, and the need for participants to maintain good mental and social health were important facilitators for engagement and are considerations for programme delivery. CARE helped PLWBC to keep physically active.

Abstract: To assess evidence on the impact of acute and chronic high intensity interval training (HIIT) and sprint interval training (SIT) on work‐related performance tests of cognitive function in adults. The databases PubMed, CINAHL, Scopus, PsycINFO, Embase, and the Cochrane Library were searched for relevant articles up to August 2022. Eligible studies assessed the effects of HIIT (70%–100% VO 2max ) and/or SIT (≥100% VO 2max ) on cognitive function test scores in cognitively healthy adults, relative to a control or comparative exercise group/condition. Data on participant characteristics, exercise protocol, key outcomes, and intervention setting were extracted. Study quality was assessed using a 9 (single session HIIT/SIT) and 14 (multiple session HIIT/SIT) item checklist. Thirty‐six studies (15 countries n = 11–945 participants) met inclusion criteria. Mean quality scores were “fair‐to‐good” for acute (single session mean = 6.9 [SD 1.0]) and chronic (multiple session mean = 9.8 [SD 1.6]) training studies. Eighteen from 36 studies (12/20 [55%] acute and 6/16 [38%] chronic training studies) evidenced significant improvements in aspects of cognitive function related to work performance (i.e., attention, inhibition, memory, information processing speed, cognitive flexibility, intelligence, reaction time, and learning). Only four studies tested the impact of HIIT/SIT on cognitive function in a work‐based setting (e.g., the office or home). While there is promising evidence, particularly from acute training studies, to indicate that high intensity, short duration exercise benefits cognitive function in adults, there is very limited evidence of application in workplace contexts. To better understand the potential benefits to employee performance and safety, HIIT/SIT and cognitive function research needs to transition from laboratory to “in‐situ” occupational settings.

Abstract: The 'Be Active Stay Healthy' (BASH) health-related exercise (HRE) programme was delivered to Year 5 students (age 9-10 years) in two primary schools situated in the same area of a northwest England town. BASH aims to improve students' participation in and knowledge of HRE through structured physical activities. Fifty-five students completed pre- and post-programme HRE knowledge and understanding questionnaires. Moderate to vigorous physical activity (MVPA) levels of 13 students were assessed using accelerometers during two contrasting lessons focusing on optimal activity levels (active) and cognitive learning (cognitive). Mean percentage of correct questionnaire answers improved from 60.8 to 83.8% (P = 0.0001, effect size (ES) = 1.44), and questionnaire performance was significantly better among students in one of the schools (P = 0.017, ES = 0.72). Boys engaged in MVPA for 11% more time than girls during the active lessons (P = 0.0006, ES = 1.21) but MVPA during cognitive lessons was similar. The BASH programme has potential to use structured physical activity as a medium to enhance students' HRE knowledge, particularly in relation to the fundamental understanding of healthy and active lifestyles. HRE knowledge may differ between schools, even when they are similarly sized and located, with analogous student catchment areas. Recommendations for the future delivery and evaluation of the programme are made.

Abstract: Increasingly the health impacts of physical inactivity are being distinguished from those of sedentary behavior. Nevertheless, deleterious health prognoses occur when these behaviors combine, making it a Public Health priority to establish the numbers and salient identifying factors of people who live with this injurious combination. Using an observational between-subjects design, a nonprobability s le of 22,836 participants provided data on total daily activity. A 2-step hierarchical cluster analysis identified the optimal number of clusters and the subset of distinguishing variables. Univariate analyses assessed significant cluster differences. High levels of sitting clustered with low physical activity. The Ambulatory & Active cluster (n = 6254) sat for 2.5 to 5 h·d −1 and were highly active. They were significantly younger, included a greater proportion of males and reported low Indices of Multiple Deprivation compared with other clusters. Conversely, the Sedentary & Low Active cluster (n = 6286) achieved ≤60 MET·min·wk −1 of physical activity and sat for ≥8 h·d −1 . They were the oldest cluster, housed the largest proportion of females and reported moderate Indices of Multiple Deprivation. Public Health systems may benefit from developing policy and interventions that do more to limit sedentary behavior and encourage light intensity activity in its place.

Abstract: This study examined whether feedback or feedback plus physical activity information could increase the number of pedometer steps taken during 1 school week. One hundred seventy-seven students (mean age 9.124 ± 1.11 years) in three elementary schools participated. Schools were randomly assigned to control (CON), feedback (FB), or feedback plus information (FB+I) groups. Children wore pedometers during school time for 5 consecutive weekdays. The total steps of the groups were recorded at the end of each school day, with students in the FB and FB+I groups free to view their step counts. In addition, the FB+I group received information and ideas about how they could increase their daily steps. The CON group received no step-count feedback or information. Students in the FB+I group achieved significantly more steps per minute (17.17 ± 4.87) than those in the FB (13.77 ± 4.06, p = 0.003) and CON (12.41 ± 3.12, p = 0.0001) groups. Information, as well as step-count feedback, increased elementary students’ school-based physical activity (number of steps) in the short term. A longer intervention period is necessary to assess the sustained impact of this type of approach.

Abstract: With increasing cancer survivorship has come an increased necessity to support people living with cancer (PLWC) to have a good quality of life including being physically active. Using mixed methods, the current study aimed to use the RE-AIM evaluation framework (Reach, Effectiveness, Adoption, Implementation and Maintenance) to determine how the football community trust delivered CARE (Cancer and Rehabilitation Exercise) intervention was able to increase participants’ physical activity in order to improve their quality of life and regain physiological and psychological function. Quantitative outcome data were collected at baseline, 3 and 6 months using the Cancer Physical Activity Standard Evaluation Framework questionnaire. Semi-structured focus groups (n = 5) captured participants’ (n = 40) lived experience of the reach, effectiveness, adoption, implementation, and maintenance of CARE. Questionnaire data were analysed using repeated measures ANOVAs and qualitative data were thematically analysed. Following diagnosis, CARE was successful in providing participants with a unique and accessible opportunity to become or restart physically activity, by providing a local, socially supportive, and inclusive environment. This resulted in significant increases in physical activity (F(1.58, 23) = 5.98, p = 0.009), quality of life (QoL) (F(2,36) = 13.12, p = 0.000) and significant reductions in fatigue (F(1.57,31) = 11.19, p = 0.000) over 6 months. Participants also reported becoming more active, recovering physical function, regaining independence, and enhanced psychological well-being as a result of attending CARE. Key design features of CARE were also identified across RE-AIM. CARE, a football community trust delivered physical activity intervention was successful in significantly improving participants’ QoL and in regaining the physical and psychological functioning of people living with cancer. Results suggest that maintaining engagement in CARE for 6 months and beyond can support people to maintain these changes. Engaging in robust evaluations such as this can help organizations to successfully secure future funding for their programs.

Abstract: This study aimed to (1) assess the day-to-day variability of children's weekday physical activity for the whole-day, and when segmented into discrete periods of the day and (2) compare boys' and girls' physical activity variability. Fifty-eight children (aged 7-11 years 31 boys) from a northwest England city wore accelerometers for 4 consecutive weekdays during November and December 2005. Intra-class correlations (ICCs) were calculated for 1 and 4 monitored days and segments of days to determine reliable estimates of moderate-to-vigorous physical activity (MVPA). The Spearman-Brown prophecy formula established the number of monitoring days required for 80% reliability. Higher ICC coefficients were typically observed among boys. Eight days of boys' whole-day monitoring were needed to achieve a reliability of 0.8, while 10 days were required for girls. The pre-school segment was the most stable (boys' ICC=0.862 girls' ICC=0.770). Compared to girls, fewer days of boys' monitoring would be required during all segments other than the school day. Day-to-day physical activity variability was sex-specific, with boys' MVPA generally more stable than girls'. The greatest reliability occurred between 7 am and 3 pm, suggesting that physical activity behaviors are more consistent in the school environment.

Abstract: The primary aim of this study was to evaluate the effectiveness of two 30-minute dietary education sessions, within cardiac rehabilitation, as a means to optimise nutrient and energy intakes. A secondary aim was to evaluate patients' habitual physical activity levels. Thirty patients (males: n=24, 61.8±11.2 years females: n=6, 66.7±8.5 years) attended a 6-week early outpatient cardiac rehabilitation programme in the UK and received two 30-minute dietary education sessions emphasising Mediterranean diet principles. Energy intakes and nutrient intakes were measured through completion of 3-day food diaries in weeks one and six (before and after the dietary education sessions) to assess the impact of these sessions on nutrient intakes. At the same time-points, a sub-group (n=13) of patients had their physical activity levels assessed via accelerometery to assess the impact of the cardiac rehabilitation programme on physical activity. Estimated energy requirements at week one (1988±366 kcal d −1 ) were not matched by actual energy intakes (1785±561 kcal d −1 ) (P=0.047, d=−0.36). Energy intakes reduced to 1655±470 kcal d −1 at week six (P=0.66, d=−0.33) whereas estimated energy requirements increased as a function of increased activity (cardiac rehabilitation sessions). Nutrient intakes remained suboptimal, while no significant increases were observed in healthy fats and fibre, which are core elements of a Mediterranean diet. Statistically significant increases were not observed in physical activity however, patients decreased sedentary time by 11±12% in week six compared with week one (P=0.009 d=−0.54). The present study findings suggest that two 30-minute dietary education sessions did not positively influence energy intakes and nutrient intakes, while habitual physical activity levels were not significantly increased as a result of the cardiac rehabilitation programme. Future research should explore means of optimising nutrition and habitual physical activity within UK cardiac rehabilitation.
