The health impact of an innovative summer camp for older adults: a pilot study using an interdisciplinary collaborative approach

Background Healthy aging with dignity and aging in place are important for Taiwanese individuals. Although Taiwan did not experience COVID-19 outbreaks prior to May 2021, many older adults have been encouraged to stay at home since the beginning of the global pandemic in January 2020. Such shelter-in-place recommendations have resulted in significant lifestyle changes, limiting activities associated with aging with dignity such as exercise and community engagement. Few studies have explored how to promote or maintain holistic health practices and physical fitness in older adults residing in rural communities during the COVID-19 pandemic. This pilot study aimed to establish an interdisciplinary collaboration with community care workers (CCWs) and evaluate the impact of an innovative summer camp (ISC) program for older adults residing in rural areas. Methods A quasi-experimental pre-post-test design with an interdisciplinary collaborative approach was implemented. The ISC program was based on a standardized protocol of modified Baduanjin exercise combined with three recreational breathing games. Participants were recruited from three community centers around the western coastal region of Yunlin County between June and August 2020. The ISC program was designed and executed by a nurse-led health promotion research team that collaborated with trained CCWs for 90 min per day, five days per week, for 12 weeks. Participants and CCWs wore facemasks during all activities. Paired t-test was used to measure changes in physical biomarkers, pulmonary lung function, and health-related fitness changes. Results Sixty-eight participants completed the ISC program. The ISC program significantly improved the participants’ physiological biomarkers and health-related fitness, including reduced body weight, waistline, and systolic blood pressure, and increased forced vital capacity, biceps arm flexion, and ability to sit and stand from a chair, step with a knee up in situ, and stand on one foot with eyes open. Most participants reported that they felt happy, satisfied, and hoped that this program would be continued in their community center. Conclusions This interdisciplinary, collaborative ISC program improved physical biomarkers and health-related fitness in older adults. Despite limitations, results strongly suggested that primary healthcare providers and CCWs can employ the described ISC program to promote wellness in older adults.

Physical education students’ usage and perceptions of a supplemental online health-related fitness knowledge curriculum (iPE)

The purpose of this study was to explore high school physical education students’ usage and perceptions of a supplemental online health-related fitness knowledge curriculum through the lens of the Unified Theory of Acceptance and Use of Technology. Individual interviews were conducted with 37 students who were enrolled in a ninth-grade physical education class. The course used an externally provided online curriculum designed to deliver and assess health-related fitness knowledge. Initial themes were generated using open and axial coding compiled into a codebook. The codebook was pilot-tested and finalized following peer debriefing sessions. Four main themes were developed: Home(room), Alone; Easy to Use, Easier to Ignore; Disconnected and Conflicted; and Low Value, Low Priority. Students completed their online work alone, but location and devices varied. Most thought the online platform was easy to navigate, and many completed multiple modules at once. Students sensed that the online content was disconnected from face-to-face physical education and questioned why they were required to engage in sedentary online learning for a physically active course. They also expressed difficulty understanding the value of the online content and assigned a low priority to completing it as a result. Implementing a supplemental online physical education curriculum presents challenges given the relative novelty of the modality within the subject. This study highlights the important role system design plays in the online learning process. It also illustrates the responsibility teachers have in helping students see the value of online learning opportunities by making connections to their own lives.

MicroRNAs as Potential Biomarkers for Exercise-Based Cancer Rehabilitation in Cancer Survivors

Expression and functions of microRNAs (miRNAs) have been widely investigated in cancer treatment-induced complications and as a response to physical activity, respectively, but few studies focus on the application of miRNAs as biomarkers in exercise-based cancer rehabilitation. Research has shown that certain miRNA expression is altered substantially due to tissue damage caused by cancer treatment and chronic inflammation. MiRNAs are released from the damaged tissue and can be easily detected in blood plasma. Levels of the miRNA present in peripheral circulation can therefore be used to measure the extent of tissue damage. Moreover, damage to tissues such as cardiac and skeletal muscle significantly affects the individual’s health-related fitness, which can be determined using physiologic functional assessments. These physiologic parameters are a measure of tissue health and function and can therefore be correlated with the levels of circulating miRNAs. In this paper, we reviewed miRNAs whose expression is altered during cancer treatment and may correlate to physiological, physical, and psychological changes that significantly impact the quality of life of cancer survivors and their role in response to physical activity. We aim to identify potential miRNAs that can not only be used for monitoring changes that occur in health-related fitness during cancer treatment but can also be used to evaluate response to exercise-based rehabilitation and monitor individual progress through the rehabilitation programme.

Physical Activity and Healthy Eating Programming in Schools to Support Student’s Health-Related Fitness: An Observational Study

Centers for Disease Control (CDC) guidelines recommend schools use a coordinated health approach to support healthy eating and physical activity. This study examines whether the number of healthy eating and physical activity programs and activities used by schools and their perceived success relate to students’ health-related fitness. This observational study used data from the Healthy Zone Schools Program. Data (collected in 2017–2019) were integrated from three sources: (1) school surveys, (2) FitnessGram®, and (3) the Texas Education Agency. Independent variables were the number of health promotion programs and activities and their perceived success; dependent variables were meeting Healthy Fitness Zone Standards (HFZ) for aerobic capacity and body mass index (BMI). We used mixed-effects logistic regression models. Fifty-six schools were in the analytic sample (n = 15,096 students with aerobic capacity data and n = 19,969 with BMI data). Results indicated the perceived success of physical activity programs/activities was significantly associated with students meeting HFZ standards for aerobic capacity (OR = 1.32, CI = 1.06–1.63). There was a significant direct association between the number of physical activity and healthy eating activities implemented (OR = 1.04, CI = 1.01–1.06) and students meeting HFZ for BMI. Schools using multiple health programs and activities need to balance the number provided with their capacity to maintain success.

Children with Poor Motor Skills Have Lower Health-Related Fitness Compared to Typically Developing Children

Most of the current empirical evidence regarding the relationship between health-related fitness and level of motor performance is based on children from high-income countries. Yet, children from low-resource areas may have fewer opportunities to develop their fitness skills. The aim of the study was to determine if South African children from both low- and middle-income areas scoring below the 16th percentile on the Movement Assessment Battery for Children-2 (probable-Developmental Coordination Disorder (p-DCD)) have lower health-related fitness levels than typically developing (TD) children. We hypothesized that children with p-DCD would have lower overall health-related fitness than TD children. A sample of 146 participants aged 10 to 11 (10.05 years (SD = 0.41)) was collected from schools in the North West Province of South Africa, on the basis of their poverty classification. Children were tested for anaerobic capacity and strength using the Bruininks–Oseretsky test of motor proficiency second edition (BOT-2) and aerobic capacity using the Progressive Aerobic Cardiovascular Endurance Run (PACER). Body composition was evaluated using body mass index corrected for age and sex (BMI-z), body fat (BF), and waist circumference. The data was analyzed using Spearman correlations and chi-squared tests. Statistically significant differences (p < 0.05) were found between groups for running and agility, strength, and aerobic capacity. No significant differences were found between p-DCD and TD groups in terms of body mass (36.1 kg vs. 33.3 kg), waist circumference (62.2 cm vs. 59.8 cm), BMI-z (19.7 vs. 17.6), and fat percentage (20.2 vs. 18.1%). Overweight and obesity prevalence was 15% in those with low socio-economic status (SES) and 27% in high SES. In conclusion, children with p-DCD had lower muscular strength, aerobic capacity, and endurance than TD children. Although it has been reported that children with p-DCD have a higher risk for overweight/obesity than TD children, this is not (yet) the case in 10–11-year-old children living in rural areas in South Africa (North West Province).

1185The association between neighbourhood built environment and health-related fitness: A systematic review

Background Few studies have investigated potential links between the built environment and health-related fitness, even though there is some evidence linking neighbourhood built environments to physical activity behaviors and chronic health conditions. Methods Following PRISMA guidelines eight databases were searched from inception to August 2020 using a combination of built environment and health-related fitness terms. Inclusion criteria was limited to quantitative studies that sampled of adults aged 18 years or older with no physical disabilities or health issues that may impact health-related fitness. Results Of the 26,219 citations identified within our comprehensive search, 25 studies met eligibility and underwent data extraction and quality assessment. Objectively measured built environment characteristics (e.g., improved sidewalks, higher street connectivity, older neighbourhoods, higher residential density, and higher land use mix) were associated with increased flexibility, cardiorespiratory fitness, grip strength, and body composition. Moreover, perceptions of neighbourhood features such as higher neighbourhood walkability, greater park access and quality, and lower neighbourhood crime, were associated with increased perceived cardiorespiratory fitness, muscular strength, flexibility, and overall fitness. However, many of these findings were from cross-sectional studies where adjustment for key confounders varied. Results also varied by sex in the small number of studies that provided sex-specific stratifications. Conclusions This project may help elucidate the pathway between the built environment and health-related fitness. Key messages Neighbourhood built environment features are associated with aspects of health-related fitness.

Through the Looking Glass: A Systematic Review of Longitudinal Evidence, Providing New Insight for Motor Competence and Health

Introduction In 2008, a conceptual model explaining the role of motor competence (MC) in children’s physical activity (PA), weight status, perceived MC and health-related fitness was published. Objective The purpose of the current review was to systematically compile mediation, longitudinal and experimental evidence in support of this conceptual model. Methods This systematic review (registered with PROSPERO on 28 April 2020) was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Separate searches were undertaken for each pathway of interest (final search 8 November 2019) using CINAHL Complete, ERIC, Medline (OVID), PsycINFO, Web of Science Core Collection, Scopus and SportDiscus. Potential articles were initially identified through abstract and title checking (N = 585) then screened further and combined into one review (n = 152), with 43 articles identified for extraction. Studies needed to be original and peer reviewed, include typically developing children and adolescents first assessed between 2 and 18 years and objective assessment of gross MC and at least one other variable (i.e., PA, weight status, perceived MC, health-related fitness). PA included sport participation, but sport-specific samples were excluded. Longitudinal or experimental designs and cross-sectional mediated models were sought. Strength of evidence was calculated for each pathway in both directions for each domain (i.e., skill composite, object control and locomotor/coordination/stability) by dividing the proportion of studies indicating a significantly positive pathway in the hypothesised direction by the total associations examined for that pathway. Classifications were no association (0–33%), indeterminate/inconsistent (34–59%), or a positive ‘+’ or negative ‘ − ’ association (≥ 60%). The latter category was classified as strong evidence (i.e., ++or −−) when four or more studies found an association. If the total number of studies in a domain of interest was three or fewer, this was considered insufficient evidence to make a determination. Results There was strong evidence in both directions for a negative association between MC and weight status. There was strong positive evidence for a pathway from MC to fitness and indeterminate evidence for the reverse. There was indeterminate evidence for a pathway from MC to PA and no evidence for the reverse pathway. There was insufficient evidence for the MC to perceived MC pathway. There was strong positive evidence for the fitness-mediated MC/PA pathway in both directions. There was indeterminate evidence for the perceived MC-mediated pathway from PA to MC and no evidence for the reverse. Conclusion Bidirectional longitudinal associations of MC with weight status are consistent with the model authored by Stodden et al. (Quest 2008;60(2):290–306, 2008). However, to test the whole model, the field needs robust longitudinal studies across childhood and adolescence that include all variables in the model, have multiple time points and account for potential confounding factors. Furthermore, experimental studies that examine change in MC relative to change in the other constructs are needed. Trial Registrations PROSPERO ID# CRD42020155799.
