ABSTRACT This article aims to describe the evolution of techniques that have enabled the proper application of the Laws of Thermodynamics for physical activity and athletes. The objective is to propose performance indicators to help add information to the current indices used in medicine and sports, such as the lactate threshold and maximum oxygen consumption. A number of analyses of the results obtained by the group were carried out for this purpose. Moreover, a discussion regarding which techniques would provide a better response to the measurements was analyzed. Some examples are the substitution of the treadmill running test with the stationary bicycle (known performed work), and a literature search in order to measure internal temperature more accurately. Level of Evidence V; Expert opinion.

Abstract Background Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques. Purpose The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness. Methods A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis. Key words included “open wrist arthrolysis,” “arthroscopic wrist arthrolysis,” “post-traumatic wrist stiffness,” and “DRUJ arthrolysis.” Data were extracted independently by a pair of reviewers. Results Overall, 637 studies were identified; 13 additional articles were found through previous publications (total 650 articles). A total of 612 records resulted after duplicates was removed. Fourteen studies were selected and only eight respected the inclusions criteria. One study focused on volar open arthrolysis and four studies on arthroscopic arthrolysis of the radiocarpal joint; two studies reported on open arthrolysis and two studies on arthroscopic DRUJ arthrolysis. Range of motion following open and arthroscopic wrist arthrolysis improved in all studies. Conclusion Both arthroscopic and open arthrolysis can lead to similar and satisfactory results in radiocarpal joint and DRUJ stiffness.. Level of Evidence This is a level 3a study.

This work aims to reorganize theoretical and empirical research on smart mobility through the systematic literature review approach. The research goal is to reach an extended and shared definition of smart mobility using the cluster analysis. The article provides a summary of the state of the art that can have broader impacts in determining new angles for approaching research. In particular, the results will be a reference for future quantitative developments for the authors who are working on the construction of a territorial measurement model of the smartness degree, helping them in identifying performance indicators consistent with the definition proposed.

Indoor And Outdoor Environments

Background: Traditional running gait analysis is limited to artificial environments, but whether treadmill running approximates overground running is debated. This study aimed to compare treadmill gait analysis using fixed video with outdoor gait analysis using drone video capture. Hypothesis: Measured kinematics would be similar between natural outdoor running and traditional treadmill gait analysis. Study Design: Crossover study. Level of Evidence: Level 2. Methods: The study population included cross-country, track and field, and recreational athletes with current running mileage of at least 15 km per week. Participants completed segments in indoor and outdoor environments. Indoor running was completed on a treadmill with static video capture, and outdoor segments were obtained via drone on an outdoor track. Three reviewers independently performed clinical gait analysis on footage for 32 runners using kinematic measurements with published acceptable intra- and interrater reliability. Results: Of the 8 kinematic variables measured, 2 were found to have moderate agreement indoor versus outdoor, while 6 had fair to poor agreement. Foot strike at initial contact and rearfoot position at midstance had moderate agreement indoor versus outdoor, with a kappa of 0.54 and 0.49, respectively. The remaining variables: tibial inclination at initial contact, knee flexion angle initial contact, forward trunk lean full gait cycle, knee center position midstance, knee separation midstance, and lateral pelvic drop at midstance were found to have fair to poor agreement, ranging from 0.21 to 0.36. Conclusion: This study suggests that kinematics may differ between natural outdoor running and traditional treadmill gait analysis. Clinical Relevance: Providing recommendations for altering gait based on treadmill gait analysis may prove to be harmful if treadmill analysis does not approximate natural running environments. Drone technology could provide advancement in clinical running recommendations by capturing runners in natural environments.

BACKGROUND: Acute normovolemic hemodilution (ANH) has been proposed as a microsurgical technique to improve blood flow in free flaps. OBJECTIVE: Here, we present the first systematic review of clinical and experimental studies on the effect of ANH. METHODS: We performed a systematic literature search of PubMed, Medline, the Cochrane Library, Google Scholar, and ClinicalTrials.gov using search strategies and a review process in agreement with the PRISMA statement and the Cochrane Handbook for systematic reviews of interventions. PICO criteria were defined before bibliometric processing of the retrieved articles, which were analyzed with the SYRCLE RoB tool for risk of bias and the GRADE scale for level of evidence. RESULTS: We retrieved 74 articles from the literature search, and after processing according to PICO criteria, only four articles remained, all of which were experimental. The rating for risk of bias was uncertain according to SYRCLE RoB results, and the level of evidence was low according to GRADE evaluation. CONCLUSIONS: There is no clinical evidence for the effect of ANH on microcirculation in free flaps, and experimental studies provide weak evidence supporting the use of hemodilution in reconstructive microsurgery.

ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

Objective. To assess the effectiveness of interventions that focus on reducing sedentary behavior (SB) among school-age youth and to identify elements associated with interventions' potential for translation into practice settings.Methods. A comprehensive literature search was conducted using 4 databases for peer-reviewed studies published between 1980 and April 2011. Randomized trials, which lasted at least 12 weeks, aimed at decreasing SB among children aged 6 to 19 years were identified.Results. Twelve studies were included; 3 focused only on SB, 1 focused on physical activity (PA), 6 were combined SB and PA interventions, and 2 studies targeted SB, PA, and diet. The majority of the studies were conducted in a school setting, while others were conducted in such settings as clinics, community centers, and libraries.Conclusions. Overall, interventions that focused on decreasing SB were associated with reduction in time spent on SB and/or improvements in anthropometric measurements related to childhood obesity. Several of the studies did consider elements related to the intervention's potential for translation into practice settings.

Barriers To Physical Activity

Background: The aims of this review were to describe exercise interventions, facilitators, and barriers to physical activity for parents of children with autism spectrum disorder. Methods: A systematic review of the literature, appraising the validity of each article with Melnyk and Fineout-Overholt’s level of evidence, from different databases CINAHL, Cochrane, PsycINFO, PubMed, ProQuest, and Web of Science between 2000 and 2020 was conducted. As the initial search revealed no articles on exercise interventions and only 2 articles with children with autism spectrum disorder, the aim was widened to all parents of children. Results: Forty-five articles were identified on barriers to physical activity including being the primary caregiving parent, perception of guilt and selfishness, and adhering to exercise programs they do as part of research, once research ends. Facilitators for physical activity including parents being more likely to exercise if they can bring their child with them and parents preferring exercise that is a lifelong habit, such as walking. Conclusions: Due to the lack of research on parents of children with autism spectrum disorder, recommendations include development and testing of interventions for parents of children with this condition including family-based exercise interventions where children and parents have a choice to exercise together.

ABSTRACT Introduction: Aerobic exercise has begun to be widely recognized as a reasonable means of preventing fat and losing weight. Scholars have confirmed that sports can help the human body lose weight and lose fat. Objective: This article measures the exercise performance indicators of subjects in different body fat percentage groups and studies the relationship between body fat percentage and exercise performance indicators. Methods: The study uses experimental methods to determine the percentage of body fat of the subjects. After physical exercise and aerobic exercise, the volunteers were tested for aerobic capacity indicators. Results: The body fat percentage of physically inactive persons was negatively correlated with aerobic and anaerobic exercise capacity indexes. Conclusion: The mechanism of aerobic exercise in weight loss treatment has the effect of promoting lipolysis and regulating blood lipid metabolism. At the same time, it has a significant influence on the number and activity of fat cells. Level of evidence II; Therapeutic studies - investigation of treatment results.
