A Review about Effect of Various Exercise Protocols on Patellofemoral Pain Syndrome in 2022

Introduction: Patellofemoral pain syndrome is one of the most common musculoskeletal disorders of the knee area. Previous studies have pointed to the positive effects of exercise. Therefore, it is very important to check the types of exercise protocols for the treatment of this condition. The purpose of the present study was to investigate the scientific framework of research related to the application of various exercise protocols on patellofemoral pain syndrome, as well as to make a favorable summary and provide more appropriate information from previous researches. In this review study, the search for articles in Persian and English languages in 2022 (until November) was carried out on WOS, Magiran, Scopus, Google Scholar, PubMed, and Springer databases. The keywords of patellofemoral pain syndrome, knee and knee rehabilitation were used to extract articles. 100 relevant articles were selected based on inclusion and exclusion criteria. After reviewing 100 articles, the number of 53 article titles that were close to the research title met the criteria for inclusion in the present study. After re-examining the articles, 25 articles were selected with the aim of examining the exercise protocol on patellofemoral pain.
 Conclusion: It seems that sports exercises with the aim of strengthening the muscles around the knee joint are effective in the recovery process and reducing the pain of people suffering from patellofemoral syndrome.

Effect of strain rates on the mechanical response of whole muscle bundle.

Muscle injuries frequently happen during sports activities and exercise, which could have serious consequences if not diagnosed and treated promptly. This research aims to investigate the quasi-static and dynamic responses of over 30 fresh frog semitendinosus muscles utilizing Split Hopkinson Pressure Bars (SHPB) and a material testing system under strain rates between 0.001 ~ 200s-1. To accommodate the special shape of muscle-tendon-bone samples, PLA clampers were produced by the 3D printer to properly hold and prevent slipping during the testing process. The mechanical characteristics of the whole muscle bundle, including Young's modulus and stress-strain curve, are illustrated at various strain rates. The findings showed that the muscle properties were sensitive to strain rate when under passive deformation. Both maximum stress and Young's modulus increased with the rise of strain rate, and modulus at 200s-1 can be as high as 10 times compared with quasi-static conditions.

RECOGNITION OF SPORTS EXERCISES USING INERTIAL SENSOR TECHNOLOGY

Supervised learning as a sub-discipline of machine learning enables the recognition of correlations between input variables (features) and associated outputs (classes) and the application of these to previously unknown data sets. In addition to typical areas of application such as speech and image recognition, fields of applications are also being developed in the sports and fitness sector. The purpose of this work was to implement a workflow for the automated recognition of sports exercises in the Matlab® programming environment and to carry out a comparison of different model structures. First, the acquisition of the sensor signals provided in the local network and their processing were implemented. The functionalities to be realised included the interpolation of lossy time series, the labelling of the activity intervals performed and, in part, the generation of sliding windows with statistical parameters. The preprocessed data were used for the training of classifiers and artificial neural networks (ANN). These were iteratively optimised in their corresponding hyper parameters for the data structure to be learned. The most reliable models were finally trained with an increased data set, validated and compared with regard to the achieved performance. In addition to the usual evaluation metrics such as F1 score and accuracy, the temporal behaviour of the assignments was also displayed graphically, which enabled statements to be made about potential causes for incorrect assignments. In this context, especially the transition areas between the classes were detected as erroneous assignments as well as exercises with insufficient or clearly deviating execution. The best overall accuracy achieved with ANN and the increased dataset was 93.7 %.

Does Exercise Addiction Exist Among Individuals Engaged in Team-Based Exercise? A Position Paper

AbstractExercise addiction is a term used to describe dysfunctional exercise behavior characterized by the classic symptoms of addictions, which eventually result in physical, psychological, or social harm to the affected individual. While well over 1000 peer-reviewed papers on problematic exercise have been published, very few studies have explored the conceptual differences between team-based and individual-based exercise, and no previous study has critically addressed this issue. The rationale for this distinction is that team-based exercise is typically organized and scheduled by others with little or no control over its timing by the individual team member. On the contrary, individual-based exercise can be self-scheduled. Consequently, more (total) control over its timing facilitates the satisfaction of craving-induced urges characterized by an addiction. It is posited that exercise addicts, in general, are “lone wolves” in the context of their addiction. Therefore, being addicted to exercise in team sports is only possible if the individual resorts to additional individually-controlled exercise above and beyond team-based training. To support this position, the present paper briefly reviews the few studies conducted in this area and examines how their results match the diagnostic interpretation of “addiction.” The present position paper highlights that “control” over the addictive behavior, in this case, exercise, is an important marker in the potential for the risk of exercise addiction. Therefore, future studies should consider that team-based exercise assigns little control to the individual. However, the extent to which additional individual-based exercise occurs and poses a risk of addiction within team exercises merits further research attention.

Sport expertise and physical exercise are associated with “hot” executive functioning: An electrophysiological examination of reward processing in collegiate athletes

ABSTRACT Objective Prior research has revealed potential effects of sports expertise and physical exercise on cognition, though there is limited research examining their effects on the “hot,” emotional-processing aspects of executive functioning (e.g., valence and reward processing important for decision-making). The present study aimed to address this gap by examining event-related brain potentials (ERPs) during a reward-processing task in athletes versus non-athletes, while also investigating if sport expertise and exercise influence this electrophysiological response. Method A total of 45 participants, including 22 athletes (55% women, 45% men) and 23 non-athlete controls (57% women, 43% men) between the ages of 18–27, completed a “virtual T-maze” environment task involving a rewarded forced choice that elicits the reward positivity (Rew-P), an ERP component associated with reward processing. Rew-P peak amplitude was compared between groups, and both sport expertise and frequency of strenuous exercise were investigated as potential predictors of the Rew-P in athletes. Results No significant Rew-P differences were found between athletes and controls (t = −1.43, p = .16, d = −.43). However, frequency of strenuous exercise (β = −.51, p = .01) and sport expertise (β = −.48, p = .01) each accounted for a significant proportion of variability in the Rew-P peak amplitude in athletes. Conclusions Results indicate that, for young adults, sport expertise and physical exercise may each account for heightened electrophysiological reward sensitivity in athletes. Potential implications are discussed for decision-making, an integral cognitive process in sports that is driven by reward processing, and the role of reward-seeking and motivation in sport proficiency.

Qualitatively investigating factors contributing to poor health and influencing unhealthy behaviour uptake in deprived areas within the UK

BackgroundUnderstanding determinants affecting poor health outcomes and influencing unhealthy behaviours within deprived areas is becoming increasingly common. This study was to investigate the participants’ Healthy Eating and Active Living (HEAL) behaviours; their attitudes, thoughts and experiences and the association with the Social Ecological Model (SEM) which could influence health behaviours.MethodData collection occurred in Barnsley an area with high levels of deprivation and health disparities. Information was gathered 97 participants across focus groups and one-to-one interviews. Questions were formulated around HEAL and SEM and questioned origin and maintenance of modifiable behaviours affecting physical activity, diet, and long-term behaviour. Deductive Thematic Analysis (Braun and Clarke in Qual Res Sport Exercise Health 11(4), 589-597, 2019) was used to analyse data.FindingsThree themes were identified: Diet and access to unhealthy options, mental health, and attitudes towards government interventions. SEM examined the effectiveness of community level interventions whilst considering the individual responsibility associated with HEAL.DiscussionWithin research area, attitudes towards HEAL are deeply impacting participants, many of these attitudes originate from childhood transferred from parents. This transference may explain why many deprived areas within England suffer from worse health outcomes, as inherited beliefs result in negative HEAL behavior manifesting in long term health problems. National interventions provided good information; but were hampered by a lack of effective dissemination to the general population. Local interventions often had more success in effectively engaging local people, but participants reported frequent shuttering of local interventions due to funding issues.

Physical activity and psychological adjustment among retirees: a systematic review

BackgroundHealth-related behaviors may change after retirement and induce changes in the mental health. This systematic review aimed to investigate the nature of changes in physical activity and leisure activities, as well as the relationship between physical activity, leisure, and psychological adjustment among retirees.MethodsSearch of papers was done in three electronic databases of PubMed, ISI Web of Science, and Scopus without constraints on time, geographical regions, or languages in February 2022. The papers that had examined the relationship between physical activity and adjustment among retirees using observational design (cross-sectional or longitudinal) were included in the present study. To evaluate the methodological quality of cross-sectional studies, Joanna Briggs Institute (JBI) Critical Appraisal Checklist, and for longitudinal studies, Newcastle-Ottawa Scale (NOS) were used.ResultsThe search results identified 1458 records. Twenty-six papers were included in this review based on the inclusion and exclusion criteria. The findings of most of these studies indicated a significant positive correlation between physical activity, leisure, and psychological adjustment in retirees. Retirees were mostly engaged in passive leisure activities such as reading, watching TV and movies, and less engaged in physical activities, sport, or physical exercise. General organized assessment of the total physical activity among retirees was not possible.ConclusionsBased on the study findings, it can be stated that there is a positive correlation between physical activity, leisure, and the retirees’ adjustment. Usage of the same and valid measurement method specific to old age and retirement period can be useful in more precise assessment of physical activity and its association with adjustment among retirees.

Factors influencing seniors' willingness to pay intention for exercise in the civil sports and recreation centers.

The increasing trend for an older population is a phenomenon that is well recognized around the world. The percentage of senior citizens participating in sports, recreation, and leisure activities is also increasing in order to sustain a healthier society. As long as seniors recognize the importance and benefits of keeping healthy, they would prefer to be active in various sports and fitness activities. The seniors could engage in making decisions about their own health by exercising regularly and by encouraging their similar-age peers. The civil sports and recreation centers (CSRCs) in Taiwan have adopted operating transfer (OT) and are located mainly in metropolitan areas, with programs consisting of indoor sports offering people daily exercise. The major aims of the CSRC are to keep the citizens in good health and not to be the city government's financial burden. The extant literature examines the determinants of general consumer behavior, neglecting studies on older adults. This study aims to explore the factors influencing seniors' willingness to pay (WTP) more for exercise in CSRCs outside of free hours. This mixed-method study consists of quantitative and qualitative analyses. For the quantitative component, we invited five experts in the sports industry from the industry and academia to evaluate the validity of the questionnaire. A questionnaire consisting of motivation, exercise involvement, and constraint constructs in the quantitative method was administered to 193 older adults in CSRCs. The collected data were analyzed through descriptive statistics, t-test, one-way analysis of variance (ANOVA), and structural equation model (SEM). Empirical results indicate that WTP in groups of people aged 75-79, 70-74, and 65-69 years is higher than in the group of people aged 85 years and above. Exercise involvement and motivation had more of a positive impact on seniors' WTP. Developing a regular exercise habits and having social interaction in exercise courses drive female seniors to pay more for body health. The results of this study provide managers of CSRCs with decision-making recommendations: (1) initiate entry-level sports courses, such as quick chair exercise, to cultivate among seniors the habit of exercise; (2) motivate seniors to participate in sports with other seniors in order to enhance their social activity and raise their WTP more for sports consumption outside of free scheduled periods; and (3) recruit seniors as exercise coaches or personal trainers to pass their experiences with other people of their age. In addition to expanding seniors' social connections, it encourages peers to exercise. Managerial implications and future research are also discussed. This study contributes to exploring the determinants of seniors' WTP intention. Motivation and exercise involvement had a significantly positive impact on seniors' WTP intention.

Magnetic bed for the treatment of different somatic diseases: design and simulation

At present, sports injuries that occur during the practice of a sport or physical exercise are becoming more and more common, due to a series of predisposing factors that make an individual more susceptible to suffer these injuries. In Cuba there is a high prevalence of articular affections of knees and ankles, with a high prevalence in people older than 60 years; in the province of Santiago de Cuba 45% of the total number of consultations correspond to soft tissue injuries. One of the applications of the electromagnetic field is in the treatment of different pathologies of the osteomuscular system (Soma). The objective of this work lies in the design of a magnetic bed with permanent magnets, in analogy to a circular Halbach type configuration for the treatment of different diseases of the soma, which consists of three main parts: the magnetic system, which generates magnetic induction for therapeutic purposes, the opening and closing system of the magnetic system, which allows the radial variation of the magnetic system and the patient-support bed system, which allows the positioning of the patient in the treatment area. The principle of operation is that the therapist selects the induction of the magnetic field and the homogeneity of the magnetic field, depending on the pathology(s) to be treated, through a software that controls the movement of the opening and closing system of the magnetic system and the patient-bed support system, which is coupled to a stepper motor reducer that ensures a precise and accurate positioning of the sample (or patient) according to the area to be treated, which allows more than 80% effectiveness of the therapy with respect to conventional treatment.

Inertial Sensor-Based Sport Activity Advisory System Using Machine Learning Algorithms.

The aim of this study was to develop a physical activity advisory system supporting the correct implementation of sport exercises using inertial sensors and machine learning algorithms. Specifically, three mobile sensors (tags), six stationary anchors and a system-controlling server (gateway) were employed for 15 scenarios of the series of subsequent activities, namely squats, pull-ups and dips. The proposed solution consists of two modules: an activity recognition module (ARM) and a repetition-counting module (RCM). The former is responsible for extracting the series of subsequent activities (so-called scenario), and the latter determines the number of repetitions of a given activity in a single series. Data used in this study contained 488 three defined sport activity occurrences. Data processing was conducted to enhance performance, including an overlapping and non-overlapping window, raw and normalized data, a convolutional neural network (CNN) with an additional post-processing block (PPB) and repetition counting. The developed system achieved satisfactory accuracy: CNN + PPB: non-overlapping window and raw data, 0.88; non-overlapping window and normalized data, 0.78; overlapping window and raw data, 0.92; overlapping window and normalized data, 0.87. For repetition counting, the achieved accuracies were 0.93 and 0.97 within an error of ±1 and ±2 repetitions, respectively. The archived results indicate that the proposed system could be a helpful tool to support the correct implementation of sport exercises and could be successfully implemented in further work in the form of web application detecting the user's sport activity.

Participation in Household Physical Activity Lowers Mortality Risk in Chinese Women and Men.

The health benefits of sport and physical exercise (SPE) have been well documented, while the influence of household physical activity (HPA) on health has received much less research attention. This study aims to provide epidemiologic insight into the role HPA plays in the development of all-cause, cardiovascular disease (CVD), respiratory disease (RESP), and cancer mortality in a nationwide cohort of Chinese adults. We conceived a prospective cohort comprising 30,791 participants aged ≥16 years from 25 provinces of China using data derived from baseline (2010) and 4 waves of follow-up (2012-2018) investigations of the China Family Panel Studies. Self-reported times of HPA and SPE were collected by interviewing participants with a standard questionnaire. Cox proportional hazard models were used to assess the associations of HPA and SPE with all-cause, CVD, RESP, and cancer mortality, adjusting for demographic and socioeconomic factors, lifestyle behaviors, and health status. A restricted cubic spline smoother was used to investigate the dose-response relationships of HPA and SPE with mortality outcomes. Sex subgroup analyses were conducted to examine the potential effect disparity between men and women. To investigate the interactive effects of HPA and SPE, we calculated the relative excess risk due to the interaction and attributable proportion of additive effects to the total observed effects. During a median follow-up of 7.2 years, a total of 1,649 deaths occurred, with 209 cases from CVD, 123 from RESP, and 323 from cancer. HPA was identified to be associated with reduced mortality outcomes, suggesting remarkably reduced risks of 43-60% in all-cause mortality, 42-50% in CVD mortality, 36-71% in RESP mortality, and 38-46% in cancer mortality. In general, higher levels of HPA tended to be associated with lower risks. An approximately inverted J-shape association was identified between HPA and all-cause and cause-specific mortality, suggesting strong evidence for potential nonlinearity. Women performing HPA had a lower risk of all-cause, CVD, and cancer mortality. We did not identify significant evidence for additive interaction between HPA and SPE. HPA is independently associated with a reduced risk of mortality in Chinese women and men. More biological studies are needed to validate our findings and clarify the mechanisms underlying the association.

Stroboscopy while Lifting Weights: A New Assessment Technique for Observing the Larynx in Strength Athletes while Lifting Weights (with and without Valsalva maneuver)

Lifting weights is a popular exercise method for improving the physical characteristics underlying performance in a wide range of sports. In order to perform these lifts safely and efficiently, strength athletes use purposeful holding of breath, strong exhalation against closed vocal cords. These are commonly known as Valsalva Maneuvers (VM) or hard glottis closures to increase core stability and reduce some of the load on the spine, and to facilitate lifting by increasing glottis closure and subsequently increasing intra-thoracic and intra-abdominal pressure. This function may expose athletes to an increased risk of laryngeal irritation or injury due to excessive pressure on the vocal cords during VM performance. Despite extensive weight training exercises in sports, its effects on vocal cords and overall laryngeal health have not yet been systematically studied. This brief methodological report describes how to safely use sports stroboscopy in strength training with weightlifting. This technique was safe and allowed to receive high quality and stable images of the larynx with minimal impact on weightlifting.

Peroneal Tendon Dislocation Treated with Arthroscopic Approach: A Case Report

Peroneal tendon dislocation is usually manifested as ankle instability and pain. Peroneal tendon dislocation is caused by ruptured of superior peroneal retinaculum (SPR) due to anatomical abnormality. SPR can be damaged due to excessive contraction force of dorsiflexion of the foot. The epidemiology of this pathology is also uncertain, because peroneal tendon dislocation is often mistaken for lateral ankle ligament sprain. The treatment should include conservative treatment and surgical treatment if it fails. A 20-year-old Indonesian Male attended orthopedic consultation with pain and snapping of the lateral side of left foot from 2 years ago after twisting his ankle during a recreational sport. Snapping was felt when doing sport exercise and in certain position. The tendon dislocation can be seen after that. On examination, he felt pain on palpation and snapping on lateral side of the ankle. The left ankle was snapped in a dorsiflexion and plantarflexion positions and can return into normal position. After conservative therapy, the condition did not improve. Then surgical intervention was suggested. Patient was operated on June 21st 2022 on a operating room with lateral decubitus position under subarachnoid anesthesia. The surgery was done with arthroscopic approach. During operation we found a SPR disruption, peroneus longus tendon longitudinal tear, low lying peroneus brevis muscle belly and shallow retromaleolar groove. These finding may increase the risk of dislocation. We performed a peroneus longus debridement, peroneal brevis muscle excision, retromaleolar groove deepening, and SPR repair are our best choice of treatment. Short leg splint and physiotherapy exercise were applied after surgery. Presented case of peroneal dislocation is very low. Usually for this case is best treated with surgical intervention. By using arthroscopy, we can detect abnormality and treat them at once. SPR repair and groove deepening with arthroscopic approach can offers a satisfactory outcome.

What are the phases of change in exercise behaviors (EB), and factors affecting exercise behaviors (EB) of male workers in a workplace setting?

The purpose of this study was to evaluate the phases of change of exercise among male workers and to analyze the factors affecting their EB using Information-Motivation-Behavioral skill-Revealed Related Variables (IMBR) model. The study included 163 male workers from a major Hyundai Transys company, Seosan city. Data were analyzed using Pearson’s correlation coefficients, and hierarchical regression etc. Regarding the phases of change in exercise, 135 individuals (82.8%) were classified into phase 3 (preparation phase), phase 4 (action phase), and phase 5 (maintenance phase). In the first step, factors such as health status (β = 0.26 , p < 0.001), smoking (β = 0.16, p= 0.005), number of exercises per week (β = 0.35, p < 0.001), times of each exercise (β = 0.17, p = 0.005), and phases of change in exercise (β = 0.17, p = 0.014) were identified as significant factors affecting EB. In the second step, health status (β = 0.19, p = 0.001), smoking (β = −0.13, p = 0.019), number of exercises per week (β = 0.31, p < 0.001), phases of change in exercise (β = 0.13, p = 0.034), and sport commitment (β = 0.16, p = 0.019) were identified as significant factors. In the third step, health status (β = 0.27, p < 0.001), number of exercises per week (β = 0.14, p = 0.005), and exercise self-efficacy (β = 0.39, p < 0.001) were identified as significant factors, explaining 68.3% of the variance in EB. To promote EB, it’s important to assess the phases of change in exercise and consider factors such as health status, smoking, the number of exercises per week and the duration of each exercise. Interventions that enhance sport commitment and exercise self-efficacy should be considered. It’s recommended to apply IMBR model in exercise studies for workers.

Construction of traditional national physical education teaching model in medical colleges from the perspective of cultural inheritance

In the context of college education, education in physical in medical schools should focus on cultivating and strengthening students' physical fitness, mobilizing students to actively participate in sports, and improving their comprehensive quality. Therefore, in the process of implementing education in physical, medical schools should fully recognize the importance of education in physical for students, and on this basis, enable students to obtain more sports knowledge and exercise opportunities. However, at present, modern education in physical is generally adopted in China's colleges and universities, and in this process, there is a lack of curriculum teaching combined with traditional national sports. However, for college students, these traditional sports activities are valuable assets for the development of education in physical, and education in physical in the new era should attach importance to and carry forward history and integrate it into education in physical in the new era. At present, the content and elements of traditional national sports courses covered in China's college education in physical courses are relatively small, therefore, from the perspective of cultural inheritance, medical schools should integrate traditional national sports into education in physical, build a relatively complete teaching system, and at the same time, have a certain understanding and mastery of certain traditional national sports in order to design a scientific and reasonable teaching program. In this regard, based on the perspective of cultural inheritance, this paper first analyses the current situation of traditional national education in physical in medical schools, and then focuses on exploring the construction strategy of traditional national education in physical teaching model in medical schools, in order to provide reference for relevant personnel.
