Modeling of Physical Activity Behavioral Interventions Relying on MPC Strategy

Physical inactivity is becoming an important threat to public health in today's society. The COVID-19 pandemic has also reduced physical activity (PA) levels given all the restrictions imposed worldwide. In this work, physical activity interventions supported by mobile devices and relying on control engineering principles were proposed. The model was constructed relying on previous studies that consider a fluid analogy of Social Cognitive Theory (SCT), which is a psychological theory that describes how people acquire and maintain certain behaviors, including health-promoting behaviors, through the interplay of personal, environmental, and behavioral factors. The obtained model was validated using secondary data (collected earlier) from a real intervention with a group of male subjects in Great Britain. The present model was extended with new technology for a better understanding of behavior change interventions. This involved the use of applications, such as phone-based ecological momentary assessments, to collect behavioral data and the inclusion of simulations with logical reward conditions for reaching the behavioral threshold. A goal of 10,000 steps per day is recommended due to the significant link observed between higher daily step counts and lower mortality risk. The intervention was designed using a Model Predictive Control (MPC) algorithm configured to obtain a desired performance. The system was tested and validated using simulation scenarios that resemble different situations that may occur in a real setting.

Preparation, Exercising, and Motivation in Sports Practice during COVID-19 Pandemic among Young Football Players in Bosnia and Herzegovina

The Covid-19 outbreak has also led to significant changes in football, such as the suspension of leagues, isolation, and the fact that football players are forced to train on their own. Therefore, the purpose of this study was to determine if there were differences in the level of preparation, practices, and motivation for athletic training among young professional football players during the Covid-19 pandemic, depending on the level of competition. The sample of respondents consisted of 82 young football players from Bosnia and Herzegovina, divided into the first league group (n=47, 18.30±0.62 age) and the second league group (n=35, 17.66±0.73 age). The questionnaire for sports preparation and training (SPEQ) was used, which consists of 11 items and was created according to the existing questionnaire for self-assessment of the level of preparation and type of training of athletes during the training process in the Covid-19 pandemic. Also, a questionnaire on sports motivation during the Covid-19 pandemic was used, consisting of 18 items related to motivation to participate in sports, modified according to the Participation Motivation Questionnaire (PMQ). A five-point Likert scale was used for the questionnaire. The questionnaire was available in electronic form and was sent to the football players through a Google form. The difference was found only in the frequency of the type of exercise in two variables, while there were no differences between the groups of young football players in the other variables of training frequency, level of preparation, and motivation in sports training. It was also established that despite the Covid-19 situation, the motivation for sports training among young football players was at a very high level. © 2023 Montenegrin Sports Academy.

Unfolding Outbreak Scenarios Can Be a Bite-Size Treat and Other Lessons From New Zealand's First Online Environmental Health Conference

The New Zealand Institute of Environmental Health (NZIEH) is a nongovernmental institute for all environmental health professionals in New Zealand. In 2021, NZIEH held its annual conference as an online virtual event for the first time. One inclusion to the program was an evolving outbreak scenario delivered in installments including "injects" of information (i.e., inserts of information relevant to the scenario) that mimic the evolution of a real-life epidemiological outbreak investigation. Questions were posed to attendees related to each added information inject. The scenario also included discussion in virtual breakout rooms that allowed attendees to network and reach consensus before responding to questions;discussions were also initiated by the scenario facilitators. Details of the scenario, its aims, evaluation of success, and limitations of this approach are discussed.

The Relationships between University Students' Physical Activity Needs, Involvement, Flow Experience and Sustainable Well-Being in the Post-Pandemic Era

As the global sustainable development agenda advances, having a healthy lifestyle has become an important part of the common pursuit. Physical activity needs and experiences are becoming increasingly diverse, yet there is a paucity of research on issues associated with university students' physical activity needs, and their perceptions of their physical activity needs and sustainable well-being are not yet fully understood. Therefore, this study combines Self-Determination Theory with the existence, relatedness, and growth (ERG) Theory of Needs to explore the mediating effects of different variables on the relationship between university students' physical activity needs and sustainable well-being. A total of 900 Chinese university students were invited through an online survey to participate in this study, and the collected data were validated with a structural equation model. According to the results of the study, it was found that the level of involvement and flow experience in university students' sports activities have a mediating effect on the relationship between needs and sustainable well-being. Therefore, educators can enhance the level of sustainable well-being by stimulating university students' physical activity needs and improving their level of involvement and participation experience.

Measuring optimal psychological conditions for teaching and learning in post-COVID-19 education

The sudden outbreak of the novel coronavirus (COVID-19) and the declaration of a pandemic caused many rapid changes to educational systems around the world in March 2020. Many issues were encountered during the transition from on-campus to online teaching and learning approaches. With educators and policymakers focusing on how best to provide quality education and scrambling to ensure that appropriate technology and teacher training were in place, mental health issues became increasingly prevalent. Positive education approaches that build on existing strengths are essential to ensure both student and teacher well-being. The Positive Workplace Framework (PWF) is an example of how a strength-based approach can improve well-being in schools. By implementing practices related to one's basic mental fitness needs and promoting team resiliency assets, schools can create optimal conditions that allow everyone to thrive and be at their best. The Mental Fitness and Resiliency Inventory (MFRI) is a validated questionnaire that provides a snapshot of a school's well-being practices, as well as a profile from which to structure plans for enhancing collective well-being among staff and students. © Springer Nature Switzerland AG 2021.

What is being uploaded on YouTube?: Analysis of fitness-related TouTube video titles pre- and post-COVID-19 in Korea. (Special issue on 2023 Asia Pacific sport and social science.)

Opportunities to participate in physical activities (PA) and fitness exercises in public and private facilities have been reduced or banned due to social distancing regulations during the height of the global pandemic. Though Korea has not experienced lockdown, several venues have been restricted to prevent the spread of Covid-19. Despite the limitations of PA engagement, people have found alternative activities by using online platforms to keep active and fit. Thus, this study focuses on analyzing fitness-related video titles from YouTube. By collecting data through text mining and conducting network analysis, it provides basic knowledge of the fitness trends from pre- and post-Covid-19. As a result, 'exercise' was found to have the highest tendency and had strong connections to keywords that indicated specific methods of working out to become fit, but it also had connections to trendy keywords such as 'hip-up' and 'body-profile' which reflect the fitness culture in Korea.

Lessons learned from the COVID-19 pandemic: implications for semiprofessional soccer clubs after the crisis- a team study

In 2019-2020 and 2020-2021, the COVID-19 pandemic led to unexpected behavioral restrictions, allowing only the individual training of the athletes. The purpose of the present study was to record the effects of a home-based training program on physical performance at a semi-professional level, after the Covid-19 confinement, in terms of external load. Twenty soccer players from one semi-professional team participated in this study. The data was collected by GPS devices, with an accelerometer and gyroscope, and a sampling rate 10Hz. The external load is evaluated by the total distance, the high-intensity runs, the sprint distance as well as the number of accelerations and decelerations. Three matches before and twelve games after the lockdown were analyzed and compared. During the confinement period, the players performed 5-6 training sessions per week. This period lasted over 4 four months. The training sessions were monitored by a free smartphone application. Similarly, the players communicated with the technical staff with a free internet application. The results showed significant increases (p < 0.05) in the total distance covered during the matches after the intervention. No significant increase in high-intensity runs and the number of accelerations were found (p > 0.05). The present data suggest that an intervention monitored by a free application could improve athletic performance at the semi-professional level, even after long-term abstinence from team training such as quarantine or off-season periods. These data might provide affordable solutions to the semi-professional soccer teams, which could be used during the off-season period leading to reduce detraining effects and higher performance in the forthcoming championship.

Self-Tracking to Do Less: An Autoethnography of Long COVID That Informs the Design of Pacing Technologies

Long COVID is a post-viral illness where symptoms are still experienced more than three months after an infection of COVID 19. In line with a recent shift within HCI and research on self-tracking towards first-person methodologies, I present the results of an 18-month long autoethnographic study of using a Fitbit fitness tracker whilst having long COVID. In contrast to its designed intentions, I misused my Fitbit to do less in order to pace and manage my illness. My autoethnography illustrates three modes of using fitness tracking technologies to do less and points to the new design space of technologies for reducing, rather than increasing, activity in order to manage chronic illnesses where over-exertion would lead to a worsening of symptoms. I propose that these "pacing technologies"should acknowledge the interoceptive and fluctuating nature of the user's body and support user's decision-making when managing long-term illness and maintaining quality of life. © 2023 Owner/Author.

Burnout syndrome and remote learning strategies during the pandemic of COVID-19: a longitudinal study of Agrarian Sciences students

Purpose:We aimed to evaluate the levels of Burnout Syndrome (BS) in Agricultural Sciences students, both before and during the COVID-19 pandemic period.Design/methodology/approach:We accessed 77 students for Burnout Syndrome using the Maslach Burnout Inventory-Student Survey (MBI-SS) on two occasions, the first in February and the second in October 2020. Sixty-three students completed both phases. The data were analyzed in a mixed factorial scheme (Three-way ANOVA;p < 0.05).Findings:Academic efficacy improved over time without interference of sex or physical activity frequency (p < 0.001). The emotional exhaustion domain significantly reduced over time in women who declared to practice physical activity (p = 0.037). A similar effect was observed in both men and women for the cynicism domain (p < 0.001). Online teaching strategies and the regular practice of exercise were associated to reduced levels of BS during the pandemic.Practical implications:The adoption of the emergency remote education system (ERE) associated with the practice of exercise can mitigate the harmful effects of the COVID-19 quarantine on the mental health of students.Theoretical implications:The ERE can be an effective strategy to mitigate BS levels in Agricultural Science students in the post-pandemic period.Originality/Value:This is the first study that presents results of BS in students of Agricultural Sciences, comparing before and during the COVID-19 pandemic.

The Effect of Telerehabilitation on Physical Fitness and Depression/Anxiety in Post-COVID-19 Patients: A Randomized Controlled Trial

Aim: The aim of this research was to evaluate the impact of a telerehabilitation program on physical fitness, muscle strength, and levels of depression and anxiety in post-COVID-19 patients. Methods: Thirty-two individuals recovered from COVID-19 (48.20±12.82 years) were allocated into either a telerehabilitation (TG n=16) or control (CG n=16) group. Physical fitness, handgrip strength, depression and anxiety levels were assessed before and after an 8-week intervention. Results: There was a significant improvement in muscle strength in both groups. Physical fitness significantly increased compared to the CG at the end of the intervention. Levels of anxiety and depression significantly decreased after the intervention when compared to the CG. Conclusion: Eight weeks of functional telerehabilitation training is a viable and efficient way to rehabilitate patients affected by COVID-19, as it improved physical conditioning and mental health. © 2023, University Library System, University of Pittsburgh.

Research on changes in physical measurement data of ordinary high school students during the COVID-19 based on big data analysis technology

The multiple comparison method refers to the hypothesis test of whether there is a significant difference between the means of each sample after the analysis of variance is performed on the samples of each group to be tested. In data analysis, the multiple comparison method can perform a more precise difference analysis based on the analysis of variance. Therefore, this study will select the LSD (Least significant difference) test method in the multiple comparison method to analyze the physical fitness test scores of males and females in the three grades from 2019 to 2021 in the investigated schools. In this way, we can understand the substantial impact of students' home-based learning on students' physical health during the new crown epidemic, so as to make targeted development plans for students' physical health in the current special period, and minimize the adverse impact of the new crown epidemic on students' physical health. © 2023 SPIE.

Research on the physical health changes of college students during the new crown epidemic based on big data analysis technology

Multiple comparisons are general term for hypothesis testing of whether there is a significant difference between the means of each sample after analysis of variance. ANOVA can only determine whether there is a difference between the population means, and multiple comparisons can further test the differences between the sample means. This study will select the LSD (Least significant difference) test method in the multiple comparison method to conduct a differential test on the physical fitness test data of four different grades from 2018 to 2021 since the COVID-19 epidemic, and analyze the physical fitness of Chinese students under the background of new coronavirus epidemic. Change characteristics of health level, and summarize relevant experience, urge relevant personnel to make targeted improvements to the future work of students' physical health training, and scientifically improve the physical health level of Chinese students. © 2023 SPIE.

Using the Theories of Planned Behaviour and leisure constraints to study fitness club members' behaviour after COVID-19 lockdown

This paper aimed to examine fitness club members' willingness to start exercising in the clubs with the end of the lockdown. The Theory of Planned Behaviour (TPB) was used in order to explore which of its components can predict club members' intention;furthermore, the degree to which leisure constraints can predict the formation of the elements of the TPB was tested. Three hundred and twenty three (N = 323) questionnaires were used;they were collected with an on-line survey, during the second lockdown in Greece. The results indicated that almost one out of three of the club members do not intend to return to the clubs when they are allowed to open. All the three elements of the TPB were contributed to the prediction of Intentions, with the Attitudes having the highest contribution. The Covid19, Hygienic and Financial constraint dimensions were the most influential on the formation of the elements of the TPB. The theoretical and applied implications of these results are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Feasibility of Virtually Delivering Functional Fitness Assessments and a Fitness Training Program in Community-Dwelling Older Adults.

The COVID-19 pandemic limited older adults' access to preventative and diagnostic services and negatively affected accessibility to age-appropriate exercise programs. The purpose of this study was to assess the feasibility of conducting guided virtual functional fitness assessments before and after participation in an 8-week virtual, live fitness program (Vivo) designed for older adults. It was hypothesized there would be no significant difference between in-person and virtual functional fitness assessments and function would improve following the program. Thirteen community-dwelling older adults were recruited, screened, and randomly assigned to in-person-first or virtual-first fitness assessment groups. Validated assessments were delivered using standardized scripts by trained researchers and included Short Physical Performance Battery (SPPB) balance, a 30 s Chair Stand Test, 8 Foot Up-and-Go Test, 30 s Arm Curl Test, and 2 min Step Test. The eight-week, twice-a-week live virtual fitness program involved cardiovascular, balance, agility, Dual-Task, and strength training. Results showed no significant differences between all but one assessment measures, and several measures improved following the eight-week program. Fidelity checks demonstrated the high fidelity of program delivery. These findings illustrate that virtual assessments can be a feasible method to measure functional fitness in community-dwelling older adults.

Review of the Literature on Ramadan Fasting and Health in 2022

Objectives The literature on health and disease during Ramadan fasting (RF) is widely spread in many journals making it not readily accessible to those interested in the subject. Here, we provide an overview of the research on the interplay of RF with various aspects of well-being published in 2022.Materials and Methods A narrative, nonsystematic review of the international literature from a single major medical online database, PubMed, in one calendar year (2022) was conducted. The search term "Ramadan fasting" was used to retrieve the appropriate records. The relevant literature with substantial data-based content was presented in a concise thematic account, excluding those concerned with diabetes.Results Themes that emerged from the review included the pathophysiology of metabolic changes during RF, nutritional aspects including body composition and energy metabolism, cardiovascular disease and risk factors, renal function and structure, endocrinology (mainly thyroid), neurological disorders, mental health, pregnancy and fetal life, and infections (including COVID). Some miscellaneous clinical themes were identified, such as patients' and professional perspectives.Conclusions In 2022, the medical interest in RF was again widely spread across specialties. Cardiovascular disease and risk factors attract the most interest in terms of original articles and professional guidelines. We hope with this review to present a concise summary of the scholarly work on the subject in this year.

Physical Activity and Nutrition Education Programs Changes Body Mass Index and Eating Habits of 12th Grade Students: An Intervention during the COVID-19 Pandemic

Background. The importance of physical activity (PA) for maintaining and improving health status increases with each passing day. Objectives. The present study aimed to examine the effects of PA and nutritional education programs applied to 12th-grade students on body mass index (BMI), PA level, and eating habits during the COVID-19 pandemic. Methods. One hundred fifty-nine 12th grade students were randomly assigned to the experimental group (EG) (n=87, 42 male and 45 female) and control group (CG) (n=72, 39 male and 33 female). At first, physical characteristics, PA level, and eating habit questionnaires were completed by students. Then, EG received a single session face-to-face PA and healthy nutrition-themed programs. After an 8-week follow-up, questionnaires were completed by students again. Also, the number of daily steps of EG was recorded during the 8-week follow-up. Differences between pre and post-BMI, PA level, and eating habits of the groups were analyzed using the mixed model ANOVA test. Results. Results showed that educational programs had a positive effect on BMI, PA level, and eating habits of EG (p<.05). There was no improvement in CG (p>0.05). Qualitative findings of EG revealed that the educational program is a beneficial process not only for a short period but also for a lifelong learning structure. Conclusion. In conclusion, PA and healthy nutrition-themed educations are effective methods to improve youths' awareness to be more active and healthier in their daily life, including during the pandemic processes.
