Bodybuilding Coaching Strategies Meet Evidence-Based Recommendations: A Qualitative Approach.

Bodybuilding is a sport where coaches commonly recommend a variety of nutrition and exercise protocols, supplements, and, sometimes, performance-enhancing drugs (PEDs). The present study sought to gain an understanding of the common decisions and rationales employed by bodybuilding coaches. Focusing on coaches of the more muscular divisions in the National Physique Committee/IFBB Professional League federations (men's classic physique, men's bodybuilding, women's physique, women's bodybuilding) for both natural and enhanced athletes, coaches were recruited via word of mouth and social media, and 33 responded to an anonymous online survey. Survey responses indicated that participant coaches recommend three-to-seven meals per day and no less than 2 g/kg/day of protein regardless of sex, division, or PED usage. During contest preparation, participant coaches alter a natural competitor's protein intake by -25% to +10% and an enhanced competitor's protein intake by 0% to +25%. Regarding cardiovascular exercise protocols, approximately two-thirds of participant coaches recommend fasted cardiovascular exercise, with the common rationale of combining the exercise with thermogenic supplements while considering the athlete's preference. Low- and moderate-intensity steady state were the most commonly recommended types of cardiovascular exercise among participant coaches; high-intensity interval training was the least popular. Creatine was ranked in the top two supplements for all surveyed categories. Regarding PEDs, testosterone, growth hormone, and methenolone were consistently ranked in the top five recommended PEDs by participant coaches. The results of this study provide insight into common themes in the decisions made by bodybuilding coaches, and highlight areas in which more research is needed to empirically support those decisions.

Method Data were based on the 2016 to 2018 Guangdong National Physique Monitoring data, in which 5242 participants aged 20-69 years were recruited. Multiple statistical analysis methods, such as descriptive and logistic regression analyses, were used to study each exercise motivation and its association with influencing factors, including sociodemographic characteristics, exercise measurements, and physical conditions. An exercise index for mental health was also used to investigate the number and types of people who were more likely to meet the index. Results We observed that 44.9% (2355/5242) of participants did not engage in physical exercise in this study. Only older participants (40 to 69 years old) and those with an average level of education (high school/technical secondary school) showed a significant association with exercising for mood regulation. Few people met the index that is good for mental health (16.64% [872/5242] met index 1, and 2.84% (149/5242) met index 2), and higher education showed a significant association with a reduction in the mental health burden and the prevention of depression. Conclusion This study found that motivating people to be more active and educating them on the potential mental health benefits of exercise could help them to exercise more.

Monitoring and Analysis of Youth Sports Physique by Intelligent Medical Robot Based on Cognitive Computing.

As a key part of promoting the physical health of the people and promoting social progress, sports has ushered in comprehensive vitality. More and more people's attention has been paid to the physical health status, especially the physical status of young people. In the field of physical fitness monitoring, although the state has continuously increased investment in human and financial resources, it still cannot meet the needs of the market. This study mainly discusses the monitoring of youth sports physique by intelligent medical robots based on cognitive computing. This study introduces the development and implementation process of the management system and the test planning of the system. It focuses on the realization of the scalable architecture of the system server application and the communication mechanism of the intelligent terminal application. With the development of collaborative computing, social computing, and the ever-changing demands of human-computer interaction, it is difficult for a single user to take into account the interactive tasks in complex scenarios. The collaborative interaction of multiusers has gradually been paid more and more attention. Teenagers can log in to the intelligent medical robot system or mobile phone terminal to make health test appointments, score inquiries, and prescription inquiries. Its display module displays different contents according to different login identities. For teenagers, it is necessary to check personal physical test results and have a position on their physical health. Through the intelligent medical robot system, the administrator records and analyzes the results of the youth health test and gives appropriate exercise prescriptions for the youth. This not only analyzes the functional requirements that meet the basic user needs, but also analyzes the nonfunctional requirements that meet the most basic security, stability, and robustness of the software. Intelligent medical systems can effectively help people learn medical knowledge better in today's postepidemic era. It also helps people to conduct self-diagnosis and self-examination of minor diseases to a certain extent, so as to improve their own health. From the functional requirements, each module of the intelligent medical robot system is functionally described. From a nonfunctional point of view, the design and implementation meet the performance requirements of client-side robustness, maintainability, and stability. Finally, the system architecture of the intelligent medical robot is designed, and the specific database table is given. During the research, 20% of the students believed that their physical condition had been improved through physical health monitoring. The state of national physique can reflect a part of the country's comprehensive national strength to a certain extent. Throughout history, the overall development trend of a society and a country is constrained by the two factors of the group's constitution and economic development. This research will contribute to the physical and mental development of adolescents. The robot designed in this paper meets the requirements of a large number of students' centralized testing and is more accurate, faster, and more convenient.

Model Construction of Urban Public Sports Service System under the Background of Information Technology

The planning and construction of urban public sports are an indispensable guarantee condition for implementing the national fitness plan, further improving the national physique and health status and improving the overall quality of the Chinese nation. With the improvement of Internet technology and various information technologies, urban public sports still publish service information such as consultation and competition through traditional information channels. The distribution channel is relatively single, the degree of informatization is not high, and the level of consulting service is low. In this paper, the model construction of urban public sports service system is studied under the background of information technology. During the period of frequency 30-40, on average, 26.8% of urban residents have participated in various sports training services; during the period of frequency 50-60, 28.6% have received professional fitness guidance services; and during the period of frequency 70-80, 27.5% have participated in professional exercise planning services. Through the model of urban public sports service system built under the background of information technology, the spread range is expanded, and the fixed participants are gradually formed. In this respect, we also enjoy the “technology dividend” of the popularity of network information technology and smart phones, which makes online booking service easier for the audience to use. We should pay attention to the diversified development of public sports service subjects, provide diversified public sports services, actively understand public sports demand, and penetrate the residents’ demand expression mechanism, so as to promote the public sports service system to form a structural state of benign interaction, joint participation, and dynamic communication.

Status Quo Analysis of Physical Fitness Test Data Based on Health Monitoring.

One of the important symbols of a country's level of social progress and the continuous spread of civilization throughout the world includes the level of national physique and health. People's living standards have been significantly improved, and a moderately prosperous society has been preliminarily realized. The national physique should be improved, especially the teenagers who are in the rapid and golden period of physical and psychological development. But not everything develops according to wishes. For the past 20 years, the physical health of Chinese students has been in a downward trend. Therefore, it is urgent to analyze and study the data of adolescent health monitoring and physical fitness test. Through the analysis of D-S evidence theory composition rules, SVM network protocol, and other technologies, the accuracy of adolescent physique monitoring data has been improved by 38.4%, enhanced students' willingness to exercise, 65% of students have enhanced physical health awareness, and a network data platform has been established, which can clearly reflect the physical health of students and summarize all monitoring data information. Teenagers are the future builders and successors of the country, and they play a pivotal role in the entire country. The analysis of the status quo of adolescent physical fitness test data is related to the strength of the country, the rise and fall of the nation, the happiness of the family, and the future of the individual.

Retracted] Health Screening and Promotion System Based on Disease Prevention

With the rapid development of modern medical technology, more and more clinicians use computerized medical images as the main diagnostic basis. At the same time, the generation of massive medical image information promotes the development of medical image management. Aiming at the above two problems, a medical image reporting system based on physical examination is designed and implemented, in which the medical image reporting system is an independent and complete system including login, registration, appointment, triage and doctor workstation (inquiry, report editing, and report printing), and other modules. Using the methods of literature review, expert interview, case analysis, and rational analysis, combined with nanotechnology research, this paper takes urban population health as the starting point and health promotion as the background. As the basis of systematic comparison, the theory, position, and function of health promotion are discussed in detail. Among them, Chinese Center for Disease Control and Prevention, World Health Organization, and Subscriber Data Center are the collection sites for the literature data mentioned in this article. With the construction of healthy towns and the development of social movements, the establishment of healthy sports to improve health promotion system aims to help sports play an important role in promoting healthy development. The results show that the average scores of step test for boys and girls in the test are 72.97 and 68.77, respectively, while the average scores of distance running in the national physique monitoring are 66 and 63. Therefore, in the newly established scoring standard, the step test scores of boys with 66 points are 72, while those of girls with 66 points are 68.

Dairy consumption and physical fitness tests associated with fecal microbiome in a Chinese cohort

Gut microbiome influenced many aspects of host physiology and psychology. Vice versa, lifestyles factors such as exercise and healthy diet are ways to shape the gut microbiota towards balance. We observed two distinct microbe groups characterized by physical fitness in a multi-omic cohort of 2183 young subjects with metagenomics, national physique comprehensive test, lifestyle and metabolome data. The panel of bacterial taxa including Clostridium bolteae, Escherichia coli, Ruminococcus gnavus, Clostridium clostridioforme, Clostridium innocuum, Bacteroides cellulosilyticus and Oscillospiraceae, were consistently associated with most of the physical fitness. Clostridium species and trace element both increased in the individuals those tend to stay up late. Yogurt consumption was associated with Streptococcus thermophilus and Bifidobacterium animalis subsp. lactis in feces, which differed from potentially endogenous Bifidobacterium species that was associated with milk intake. Our large-scale analyses were poised to advise for a healthy gut microbiome through behavioural changes.

Hand grip strength is associated with cardiopulmonary function in Chinese adults: Results from a cross-sectional study

BackgroundThe objective of this population-based study was to examine whether there was association of hand grip strength (HGS) with cardiopulmonary function in population without cardiopulmonary disease. MethodsData were derived from an ongoing cross-sectional survey of the National Physique and Health in Shanxi Province. There were 908 participants with the cardiac function tests and 380 participants with the pulmonary function tests. Multiple linear regression analysis was used to assess the association of HGS with cardiopulmonary function. ResultsAmong participants with the cardiac function tests, HGS was positively associated with left ventricular end diastolic diameter in both genders (male: b = 0.010 (0.005, 0.015), P < 0.001; female: b = 0.008 (0.002, 0.014), P = 0.01) and left ventricular ejection fraction in males (b = 0.114 (0.027, 0.201), P = 0.01). Among participants with the pulmonary function tests, HGS was positively associated with vital capacity (male: b = 0.033 (0.021, 0.045); female: b = 0.033 (0.021, 0.045)), forced expiratory volume in 1 s (male: b = 0.023 (0.014, 0.032); female: b = 0.019 (0.010, 0.028)) and maximal voluntary ventilation (male: b = 1.186 (0.665, 1.708); female: b = 0.965 (0.453, 1.476)) in both genders (all P < 0.001). ConclusionsThese results suggested that greater HGS was associated with favorable cardiopulmonary function in Chinese adults, thus HGS might be an indicator of cardiopulmonary function.

Med-PPPHIS: Blockchain-Based Personal Healthcare Information System for National Physique Monitoring and Scientific Exercise Guiding.

The dissemination of electronic medical data among professional personnel has been perceived to be an important breakthrough for the discovery of new technologies and therapies for curing diseases. However, in the current medical data management, it is difficult to share medical data due to the fragmentation of medical data and the lack of effective sharing methods. On the other hand, the security of medical data is difficult to protect because the centralized data storage is vulnerable to attack and tampering. Therefore, we propose a model called Med-PPPHIS, which consists of a permission-less blockchain and a permissioned blockchain, named Med-DLattice, to serve the management of user's personal health information and form a chained protection mechanism for medical data. Med-DLattice features Directed Acyclic Graph (DAG) structure, where each account updates its Account-DAG asynchronously to other unrelated accounts. The Med-DLattice nodes can reach an efficient consensus with proposed DPoS-Quorum algorithm. Based on this model, by converting the medical data into on-chain tokens, a safe and efficient channel for data circulation is established, while the privacy of data is secured. We implement a prototype of Med-PPPHIS and introduce a blockchain-based closed-loop method for chronic disease management, which initially applies the model to national physique monitoring in Anhui Province, China. The performance of the model is evaluated by simulating 500 nodes on 25 AliCloud ECS virtual machines. Experimental result shows that Med-PPPHIS has low latency and high throughput, and the security analysis shows that the model is able to prevent Sybil attacks, DDoS attacks, etc.

BMI better explains hypertension in Chinese senior adults and the relationship declines with age.

Researchers have been examining the relationship between obesity and hypertension. However, whether overall or abdominal obesity better explains senior adults' hypertension has not been studied. The purpose of the study was to examine whether body mass index or waist circumference better predicts hypertension in Chinese senior adults and how the magnitude of the relationship is attenuated as they continue to age. The study was based on the 2010 National Physique Monitoring data. There were 7,542 senior adults aged 60-69 years living in urban, suburban, and rural areas of Shanghai City. The participants were categorized into five age groups: 60-61, 62-63, 64-65, 66-67, and 68-69 years. The percentage of participants who had hypertension increased as people aged, which was mainly caused by the increase of systolic blood pressure. Logistic regression analysis showed that when body mass index or waist circumference was entered into the model, both were significant predictors for hypertension (p < 0.05). However, when body mass index and waist circumference were mutually entered into the model, body mass index was the only important predictor (p < 0.05). The values of odds ratios were found to decrease from the 60-61 to 68-69 years age groups. More senior adults have hypertension as they age. Body mass index, and not waist circumference, better predicts Chinese senior adults' hypertension. However, age attenuates the effects of obesity on hypertension as the senior adults continue to age.

Monitoring Health and the Body: Anthropometry, Lifestyle Risks, and the Japanese Obesity Crisis

The 2008 introduction of the special health checkup ( tokutei kenkō shinsa ) signaled a major shift in Japan’s health policy away from a high-risk approach toward a population approach based on the epidemiological probability of contracting a disease. This article places the government’s concern with mapping obesity within its longstanding interest in surveying the national physique and sociological debates on risk in late modernity. The empirical case study outlines the making of the obesity crisis, its main actors, and their interests. Far from being an objective risk, obesity emerges as a social construct and a major apparatus of neoliberal politics through which individuals are encouraged to engage in self-regulation.
