ABSTRACT
A motivação é um fenômeno complexo que impulsiona as ações humanas. O diagnóstico de tais interesses oferece elementos de reflexão para a promoção de atividades e a implementação de políticas públicas. Neste contexto, o presente trabalho tem o objetivo de analisar as motivações dos praticantes de ciclismo recreacional de Blumenau/SC, município com uma população de 363 mil habitantes e uma malha cicloviária de 137 quilômetros. A coleta dos dados empíricos da pesquisa ocorreu por meio da aplicação de um questionário. Ao final, obteve-se uma amostra de 304 respondentes. Os resultados do estudo indicam a motivação para as atividades físicas ocupa papel central na relação com outros fatores de interesse, contribuindo para a superação de aspectos eventualmente desencorajadores. Em contrapartida, praticantes que têm outras motivações, como a interação social e o desenvolvimento pessoal, dependem mais de estímulos encorajadores, o que sugere que em tais casos existe a necessidade de maior incentivo para a prática do ciclismo recreacional. As conclusões deste estudo são relevantes para planejadores urbanos e gestores de comunicação. Ao mensurar a pertinência de causas motivadoras e desmotivadoras do ciclismo, os resultados da pesquisa indicam a importância de investir em infraestrutura adequada como a expansão da rede cicloviária e a criação de campanhas de divulgação, a fim de promover a bicicleta como meio de transporte e/ou recreação.
Motivation is a complex phenomenon that drives human actions. Diagnosing these interests provides elements for reflection in promoting activities and implementing public policies. In this context, the present study aims to analyze the motivations of recreational cyclists in Blumenau, SC (Brazil), a city with a population of 363,000 inhabitants and a cycling network of 137 kilometers. Empirical data for the research were collected through a questionnaire. Ultimately, a sample of 304 respondents was obtained. The study's results indicate that motivation for physical activities plays a central role in the relationship with other factors of interest, contributing to overcoming potentially discouraging aspects. Conversely, individuals motivated by other factors, such as social interaction and personal development, rely more on encouraging stimuli, suggesting that in such cases there's a need for greater incentives for recreational cycling. The conclusions of this study are relevant for urban planners and communication managers. By assessing the relevance of motivating and demotivating factors in cycling, the research results underscore the importance of investing in appropriate infrastructure, such as expanding the cycling network and launching promotional campaigns, to promote cycling as a means of transportation and/or recreation.
ABSTRACT
A presença das bicicletas em Fortaleza, uma capital brasileira que tem ampliado a oferta de rotas cicláveis, ciclovias e ciclofaixas, é notada em diversas regiões da cidade e pode ser percebida como elemento fundamental na paisagem e tem forte influência nas alterações do tecido urbano de Fortaleza, desde a intensa manifestação cidadã em sua defesa como meio de transporte ou através da arte urbana. O estudo baseia-se em pesquisa exploratória, bibliográfica e documental, com observação participante e realização de grupo focal; traz reflexões sobre a bicicleta como bem simbólico, como elemento comunicativo, indutor do direito à cidade e instrumento de desenvolvimento urbano sustentável. Dialogando com Armando Silva (2014), Jane Jacobs (2011), Michel Maffesoli (2014), Fernanda Sánchez (2010), Jean-Mar Besse (2014), arguimos a importância do artefato bicicleta como elemento dinâmico na composição da paisagem cultural de Fortaleza.
The presence of bicycles in Fortaleza, a Brazilian capital that has expanded the offer of cycling routes, cycle paths and cycle lanes, is noted in several regions of the city and can be perceived as a fundamental element in the landscape and has a strong influence on changes to the urban fabric of Fortaleza, from the intense citizen demonstration in defense of it as a means of transport or through urban art. The study is based on exploratory, bibliographic and documentary research, with participant observation and focus groups; brings reflections on the bicycle as a symbolic asset, as a communicative element, an inducer of the right to the city and an instrument of sustainable urban development. Dialoguing with Armando Silva (2014), Jane Jacobs (2011), Michel Maffesoli (2014), Fernanda Sánchez (2010), Jean-Mar Besse (2014), we argue the importance of the bicycle artifact as a dynamic element in the composition of the cultural landscape of Fortaleza.
ABSTRACT
Objective To compare the discrepancies among results of three commonly used laboratory direct test methods for maximal oxygen uptake(VO2max),explore their linear regression relationships,mutual predictability and comparability.Methods Using a quasi-experimental design of cluster sampling and within-group interaction design,20 male cross-country skiers were tested for VO2max using the Bruce protocol(Method 1),90-second incremental load exercise on power bicycle(Method 2),and 1-minute incremental load exercise on treadmill(Method 3),with an interval of one week.The indepen-dent and dependent variable were the three VO2max test methods and the VO2max,respectively.Results Significant differences were found in the average VO2max of the three test results,with the value mea-sured by Method 1 ranking the first,followed by that assessed by Method 3 and Method 2(P<0.05).Moreover,the frequency of individual differences in the results of the three methods showed that the VO2max of Method 1 was about 6 and 3 ml/min·kg higher than that measured by Method 2 and 3.However,at the same treadmill speed,the average blood lactate evaluated using Method 3 was higher than Method 1,and the speed reached aerobic and anaerobic thresholds about one speed unit(1 km/h)lower than Method 1.Meanwhile,linear regression analyses of the test results between Method 1 and 2,as well as Method 1 and 3 showed that both the regression models and coefficients were statis-tically significant(P<0.001),with the R-squared values of 9.25 and 9.05,respectively.Conclusion The Bruce protocol performs best in assessing the maximum value of the athlete's VO2max phase,whose results have linear regression relationships with the other two methods,and can be used for pre-dicting their results.Moreover,athletes of different events and levels can choose different VO2max test methods accordingly.Lastly,the speed and heart rate ranges corresponding to the aerobic and anaero-bic thresholds can serve as an effective and convenient method to control the training intensity.

ABSTRACT Older adults should perform physical activity to improve cardiorespiratory functions. Aerobic exercises improve cardiovascular function, decrease basal heart rate and blood pressure, and improve mood and energy. To facilitate the execution of aerobic physical activity in older adults, the objective of this research was to design an exercise device for older adults. Starting from design specifications such as comfort, size, weight, resistance, and cost, we developed the detailed design of a horizontal bicycle. The designed device, thanks to its horizontally disposed structure, its adequate resistance to pedaling, its dimensioning based on anthropometric measurements of the Chilean population, and the disposition of sensors for heart rate and oxygen saturation, is suitable for older adults. Its weight and size also make it convenient for use inside the home, and the use of materials, components, and manufacturing processes available nationally and within the cheapest options, increases the possibility of access by older adults.
RESUMEN Es fundamental que los adultos mayores realicen actividad física para mejorar las funciones cardiorrespiratorias, particularmente los ejercicios aeróbicos mejoran la función cardiovascular, disminuyen la frecuencia cardíaca basal y la tensión arterial, además de mejorar su estado de ánimo y energía. Con la finalidad de facilitar la ejecución de actividad física del tipo aeróbica en adultos mayores, se planteó el objetivo de este trabajo, centrado en diseñar un dispositivo para su ejercitación. Partiendo de especificaciones de diseño como comodidad, tamaño, peso, resistencia y costo, se desarrolló el diseño de detalle de una bicicleta horizontal. El dispositivo diseñado, gracias a la disposición horizontal de la estructura, la resistencia adecuada al pedaleo, su dimensionamiento con base a medidas antropométricas de población chilena, y la disposición de sensores para heart rate and oxygen saturation, es adecuado para adultos mayores. Además, su peso y tamaño lo hacen conveniente para el uso dentro de las viviendas, del mismo modo, el uso de los materiales, componentes y proceso de manufactura disponibles nacionalmente y dentro de las opciones más económicas, aumentan la posibilidad de acceso por parte de los adultos mayores.
ABSTRACT
Objective To explore the effect of gum chewing combined with in-bed bicycle pedalling exercises on puerpera in first flatus and early ambulation after caesarean section so as to provide an effective approach to promoting maternal recovery after caesarean section.Methods A total of 80 puerpera from a general hospital in Guangzhou were selected as the study subjects by convenience sampling method.The puerpera who received caesarean section between October and December 2021were assigned to the control group(n=40)and the puerpera who received caesarean section between January to March 2022 were assigned to the observation group(n=40).Puerpera in the control group received routine nursing,while those in the intervention group were treated with a combination of gum chewing and in-bed bicycle pedalling exercises.The time of the first flatus and the time of ambulation 24 hours after intervention were observed and compared between the groups.Results All puerpera in the two groups completed the study.The time of the first flatus in the observation group was significantly earlier than that in the control group(25.63±11.39 hours vs.30.85±10.65 hours,P<0.05).The time for first ambulation in the observation group was shorter than that in the control group(34.89±4.83 h vs.39.0±4.15,P<0.05).Conclusions Gum chewing combined with bicycle-pedalling exercises can help an early flatus,help puerpera to achieve an earlier ambulation,and improve early rehabilitation after caesarean section.The method is simple,feasible,comfortable,safe and easy to be accepted.
ABSTRACT
ABSTRACT Bicycle paths are important infrastructures in the cities to promote active commuting. Thus, understanding the information inherent to their quality might help to understand their effects on human behavior. This study aimed at assessing the quality of the bike paths in the city of Florianopolisl by using the QualiCicle instrument. SOPARC tool was used to verify the use profile. A total of 38 cycling axes with a length of 54 km were selected. The qualitative analysis was classified as sufficient, with an overall average of 1.61 points. A total of 6,113 cyclists were observed; the majority was adult men who used to cycle in moderate intensity. Better-quality bike paths had a greater number of cyclists (50.5%). The logistic regression analyzes showed that young people are less likely to use cycle paths classified as 'good' ones (OR: 0.40; 95% CI: 0.24-0.67). Considering per category, there is a greater chance of women to use bike paths with a 'good/excellent' infrastructure quality, and a 'sufficient' and 'good/excellent' signalization. It is concluded that Florianopolis has an adequate bikeway network; however, the infrastructure distribution and the cycle path connections are irregular along the city regions. A better quality of the cycling infrastructures can promote greater use by women and the elderly, groups that perform less physical activity.
RESUMO Ciclovias são estruturas importantes nas cidades para promover o deslocamento ativo. Assim, compreender as informações inerentes à sua qualidade pode auxiliar na compreensão de seus efeitos sobre o comportamento humano. O objetivo deste estudo foi avaliar a qualidade das ciclovias de Florianópolis por meio do instrumento QualiCiclo. O instrumento SOPARC foi utilizado para verificar o perfil de uso. Foram selecionados ao todo 38 eixos de ciclovias com 54 km de extensão, sendo a análise qualitativa classificada como suficiente, com média geral de 1,61 pontos. Foram observados 6.113 ciclistas dos quais a Mayria eram homens, adultos e em intensidade moderada. As ciclovias de melhor qualidade possuem Mayr número de ciclistas (50,5%). As análises de regressão logística mostraram que, usualmente, jovens possuem menos chance de utilizarem as ciclovias classificadas como "boa" (OR:0,40; IC95%: 0,24-0,67). Quando observado por categoria, há uma Mayr chance de mulheres utilizarem os eixos de ciclovia que possuem "boa/ótima" qualidade de infraestrutura e "suficiente" e "boa/ótima" qualidade de sinalização. Conclui-se que Florianópolis possui uma rede de ciclovias adequada, contudo, a distribuição das estruturas e conexão de ciclovia é irregular entre as regiões da cidade. Uma Mayr qualidade da infraestrutura cicloviária pode promover Mayr uso por mulheres e idosos, grupos que menos realizam atividade física.
ABSTRACT
ObjectiveTo explore the status and influencing factors of electric bicycle (e-bike)-related traffic injury in Songjiang District of Shanghai, and to provide reference for prevention and control of the injury. MethodsA self-designed questionnaire was used to investigate the community residents over 16 years old who rode e-bike in Songjiang Western Industrial Zone. The survey included general demographic characteristics, physical and psychological conditions, e-bike use, accidents and injuries. Descriptive analysis, chi-square test and Fisher's exact probability method were used to explore the influencing factors of traffic injury by e-bike in Songjiang District. Results1 030 questionnaires were distributed and 1 013 valid questionnaires were recovered. The effective rate of the questionnaire was 98.35%. From June 2020 to May 2021, the incidence of e-bike traffic accidents in Songjiang Western Industrial Zone was 17.47% and the incidence of injuries was 12.64%. The difference between e-bike accident group and non accident group was statistically significant (P<0.05) in the following factors: gender, registered residence, educational level, sleeping time, fatigue, violation of traffic regulations including speed limit 25 km‧h-1 and crossing of red traffic lights, riding after alcohol drinking, riding speed higher than 30 km‧h-1, riding on the phone, wearing headset, turning without prompting signal, riding on the lane of motor vehicles,and e-bike life. The top three injured body parts were limb pelvis (48.10%), body surface (27.85%) and head (13.92%). The nature of injury was mainly contusion / abrasion (82.03%), followed by fracture (17.19%). ConclusionThe incidence of e-bike traffic accidents in Songjiang District is high. We should strengthen the traffic safety education of e-bike riders, strengthen the road traffic control, and reduce the occurrence of e-bike road traffic accidents in Songjiang District.
ABSTRACT
Analisar o padrão do deslocamento ativo da Região Metropolitana Campinas, levando em conside-ração particularidades dos residentes e suas viagens. Utilizando as bases de dados obtidas através da Pesquisa Origem e Destino da Região Metropolitana de Campinas dos anos de 2003 e 2011, foram realizadas estatísticas descritivas e temporais a partir das características dos sujeitos, municípios e via-gens. Para identificarmos diferenças adotamos o intervalo de confiança de 95% (IC 95%). Utilizamos a regressão de Poisson para verificação da correlação entre características individuais e o desfecho ser ciclista ou caminhante, adotando o valor de p < 0,05. Todos os dados foram analisados levando-se em consideração os procedimentos de amostragem para que a amostra fosse representativa. Cons-tatou-se que a frequência de ciclistas e caminhantes e suas respectivas viagens caíram. Encontramos associação positiva para ciclista ser homem e classes econômicas mais baixas, para os caminhantes houve associação positiva ser mulher e crianças/adolescentes. Quanto ao tempo de viagem, notou-se aumento na mediana para os ciclistas e queda para os caminhantes. Não encontramos nenhuma via-gem de bicicleta que faça integração com outro modo de transporte. Quanto ao porte do município, observou-se uma queda em viagens de bicicleta tanto nos municípios pequenos, médios e grandes, e os residentes de Campinas apresentaram as menores frequências
This study analyzes the active commuting pattern of the Metropolitan Region of the City of Campinas, Brazil, by considering its commuters and their features. By using the database of Pesquisa Origem e Destino (a Brazilian instrument for transportation planning) of Campinas Metropolitan Region 2003-2011, we present descriptive and temporal statistics concerning the characteristics of the region's commuters, cities, and journeys. To assess those, we adopted a confidence interval of 95% (CI 95%). We used the Poisson regression to check the correlation between individual characteristics and outcomes of being a cyclist or a pedestrian, adopting the value of p < 0.05. We took into consideration the procedures for datum obtaining to present representative samples, verifying that the number of both cyclists and pedestrians has dropped. We found pos-itive associations regarding low-income males and being a cyclist; as well as females and children/teenagers and being pedestrians. The mean length of commuting time has increased for cycling journeys and decreased for pedestrian ones. We could not find a bicycle journey that integrates with another mean of transportation. Regarding the size of a city, we observed that the number of cycling journeys has dropped in small, medium, and large municipalities; Campinas presents the lowest index

ABSTRACT This study investigated the effect of an intervention on perceptions of barriers for the bicycle use in commuting to work by industrialists. 876 men (mean age = 35.4 ± 9.5 years) from a metallo-mechanical company participated. The sample was randomized into a control and intervention group (438 participants in each group) considering the use or not of the bicycle when commuting to work. The intervention had 23 meetings of approximately 30 minutes each, spread over six months, based on the Transteoric Model of Behavior Change (TMBC). The perception of barriers to bicycle use was assessed using the "scale to assess the perception of barriers to bicycle use". Descriptive statistics, chi-square, Wilcoxon test, Kruskal-Wallis and Mann-Whitney were applied for analysis, adopting p < 0.05. There was a statistical decline in perception of barriers to bicycle use in the intervention group (Z = -2.218; p = 0.027). When stratified by age group, greater effectiveness of the intervention was observed in reducing in the perception of barriers in individuals aged 30-39 years (Z = -2.637; p = .008). For the other age groups, there were no significant differences. It is concluded that interventions based on TMBC are effective to decrease the perception of barriers for bycicle use in the commuting to work.
RESUMO Esse estudo investigou o efeito de uma intervenção na percepção de barreiras para o uso de bicicleta no deslocamento ao trabalho de industriários. Participaram 876 homens (idade média = 35,4 ± 9,5 anos) de uma empresa metalomecânica. A amostra foi randomizada em grupo controle e intervenção (438 participantes em cada grupo), considerando o uso ou não da bicicleta ao trabalho. A intervenção contou com 23 encontros de 30 minutos cada ao longo de seis meses, baseados no Modelo Transteórico de Mudança de Comportamento (MTMC). A percepção de barreira para uso de bicicleta foi avaliada por meio da "escala de percepção de barreiras para o uso de bicicleta". Para análise foi aplicada estatística descritiva, qui-quadrado, teste de Wilcoxon, Kruskal-Wallis e Mann-Whitney adotando p < 0,05. Houve redução estatística na média da percepção de barreiras para uso de bicicleta no grupo intervenção (Z=-2,218; p=0,027). Quando estratificado por faixa etária, observou-se maior eficácia da intervenção na redução da percepção de barreiras em indivíduos na faixa etária de 30-39 anos (Z=-2,637; p=0,008). Para as demais faixas etárias, não houveram diferenças significativas. Conclui-se que intervenções baseadas no MTMC são eficazes na redução da percepção de barreiras para o uso da bicicleta para o deslocamento ao trabalho.

INTRODUCCIÓN: Los accidentes en bicicleta son una causa frecuente de trauma abdominal contuso en pediatría. En Chile no existen publicaciones científicas que traten sobre las lesiones abdominales por manubrio de bicicleta, su presentación y manejo. OBJETIVO: Describir tres casos clínicos de trauma abdominal contuso provocados por manubrio de bicicleta en niños, ilustrar las distintas lesiones observadas, sus formas de presentación y manejo. CASOS CLÍNICOS: 1) Paciente masculino, 11 años, consulta tras golpe con manubrio de bicicleta en epigastrio; en la Tomografía Computada (TC) de abdomen y pelvis se describió neumoretroperitoneo. Se realizó laparotomía exploradora, reparándose una perforación duodenal. 2) Paciente masculino, 14 años, consulta tras golpe en el hipocondrio izquierdo con el manubrio de la bicicleta; en la TC se evidenció fractura esplénica con múltiples laceraciones. Por la presencia de sangrado activo se trató con angioembolización, lográndose resolución de la lesión y viabilidad del órgano luego de 6 semanas de seguimiento. 3) Paciente masculino, 9 años, ingresó tras sufrir golpe con manubrio de bicicleta en el hipocondrio derecho. En TC se observó una laceración hepática, que fue manejada de forma expectante, con resolución de la lesión luego de 8 semanas de seguimiento. Todos los pacientes tuvieron una evolución favorable. CONCLUSIÓN: El trauma abdominal contuso por golpe con manubrio de bicicleta puede ser potencialmente grave en pacientes pediátricos, pudiendo afectar órganos sólidos y vísceras huecas. El manejo no quirúrgico cada vez es más utilizado, logrando altas tasas de éxito en pacientes estables. Los pacientes inestables o en los que se sospeche perforación de víscera hueca, requerirán cirugía como primera aproximación.
INTRODUCTION: Bicycle accidents are a frequent cause of blunt abdominal trauma in children. In Chile, there are no scientific articles about such accidents, their presentation and management. OBJECTIVE: The aim of this study is to describe three cases of blunt abdominal trauma due to handlebar injury in children, in order to illustrate the different kinds of lesions, their presentation, and management. CLINICAL CASES: 1) 11-year-old boy presented to Emergency Department (ED) after falling on a bi cycle handlebar, hitting his epigastric region. A CT scan showed signs of duodenal perforation. A la parotomy was performed and the duodenal perforation repaired. 2) 14-year-old boy seen at ED after a bicycle accident in which the handlebar hit him in the abdomen area. A CT scan showed a splenic injury with multiple lacerations and active bleeding that was treated with angioembolization. After 6 weeks of follow-up, he presented resolution of the lesion and viability of the spleen. 3) 9-year-old boy admitted due to a hit with the bicycle handlebar on the abdomen area. A CT scan showed a he patic injury that was managed with non-surgical procedures, achieving resolution of the lesion after 8 weeks of follow-up. CONCLUSION: Blunt abdominal trauma caused by handlebar can be potentially serious in pediatric patients, since it may affect solid and hollow abdominal viscera. Non-surgical ma nagement is becoming more used for stable patients, achieving high success rates. Unstable patients or those with suspicion of hollow viscera perforation will require surgery as first approach.

ABSTRACT
Objective: To assess the relationship between bicycle ownership status and physical activity, time of sitting, overweight or obesity in China. Methods: Based on the information of China cohort from Prospective Urban Rural Epidemiology (PURE) study, we conducted a cross-sectional description. Multivariable linear and multivariable Logistic regression analysis were respectively used to distinguish the differences of physical activity, time of sitting, overweight or obesity status between bicycle owners and non-bicycle owners. Results: A total of 42 677 participants were analyzed, the average age was (51.23±9.72) years including 40.9% male. There were 27 744 (65.0%) bicycle owners, their MET-min/week for total physical activity, work, transportation,domestic and recreation time were 2513.00 (1114.00, 5271.00), 444.00 (0.00, 735.00), 420.00 (0.00, 990.00), 600.00 (180.00,1260.00) and 198.00 (0.00, 693.00) respectively; time of sitting was (1397.03±832.13) min/week and waist circumference was (81.03±10.53) cm. With adjusted potential confounders, bicycle owners had more transportation activity, while less total physical activity, work, domestic and recreation time than non-bicycle owners; bicycle owner had more time of sitting and less risk of obesity; BMI and waist-to-hip ratio were similar between bicycle owners and non-bicycle owners. Conclusion: Bicycle owners had more transportation related physical activity and less risk of obesity; while the total physical activity, domestic and recreation related physical activity might be reduced in them.
ABSTRACT
PURPOSE: This study aimed to investigate bicycle injury patients who suffered orthopedic injuries. METHODS: From January 1, 2010 to December 31, 2014, 1,664 people visited the emergency room due to a bicycle accident. Among them, 385 patients were found to have orthopedic injuries through physical examination and imaging evaluation. Intending to evaluate whether the number of bicycle injury patients is increasing or decreasing yearly, we investigated the rate of orthopedic injuries among bicycle injury patients, the damaged areas and the extent of damage, and also investigated whether changes in frequency were correlated with sex, age, or season. RESULTS: From January 1, 2010 to December 31, 2014, a total of 237,533 people came to the emergency room. Among them, the number of bicycle injuries was 1,664 (0.7%), and 23% of the bicycle injuries (385 people) were orthopedic injuries. Among these, 77.4% were men, 44.5% were less than 20 years old, and 20% were more than 61 years old. Damage to the forearm (n=82, 21.3%) and the shoulder (n=71, 18.4%) were the most common injuries, and simple fractures affected 274 patients (71.1%), overwhelmingly more common than other patterns of damage. In combination, simple fracture and dislocations occurred in 279 cases (72.5%). CONCLUSION: Most bicycle injuries occur in young and elderly people. Fractures of the forearm and shoulder were the most common orthopedic injuries. We expect that this study will be helpful in providing information about the orthopedic characteristics of bike injuries.

With the steady rise of health and environmental awareness, the number of bicyclists is increasing. However, there are few epidemiologic studies on bicycling under the influence (BUI). The aim of this study was to determine the prevalence of BUI and the associated risk factors in a representative Korean population. The data of 4,833 adult bicyclists who participated in the Korean National Health and Nutrition Examination Survey (2010–2012) were analyzed. Among the 4,833 participants investigated in this study, 586 (12.1%) had experienced BUI. As participants’ age increased, so did the prevalence of BUI (P < 0.001), with the participants who were aged 60–69 showing the highest prevalence of BUI (19.6%). With regard to BUI and drinking habits, the likelihood of being a heavy or high-risk drinker increased with the frequency of BUI (P < 0.001). In addition, there was a positive relationship between the frequency of BUI and alcohol use disorder identification score level. Finally, those who had previous experiences of BUI were significantly more likely to drive and ride motorcycles under the influence (P < 0.001). In conclusion, the prevalence of BUI was 12.1% and several associated risk factors for BUI were elucidated in this study. The development of specific preventive strategies and educational programs aimed at deterring individuals at a high risk of engaging in BUI is expected to reduce the number of alcohol-related bicycle injuries.

OBJECTIVE: Head injury is the main cause of death and severe disability in bicycle-related injuries. The purpose of this study was to compare the demographic characteristics and injury mechanisms of bicycle-related head injuries according to the severity and outcome and determine the main risk factors and common types of accompanying injuries. METHODS: A total of 205 patients who were admitted to the neurosurgery department of our hospital for bicycle-related head injuries between 2007 and 2016 were analyzed. We categorized the patients into two groups according to severity and outcome of head injury, and then identified the differences in age, sex, and cause of injury between the two groups. RESULTS: Collisions with a motor vehicle increased the risk of severe head injury (p=0.011), resulted in poor outcomes (Glasgow Outcome Scale [GOS] ≤3; p=0.022), and caused more accompanying chest/abdominal (p<0.001) and pelvic/lower extremity injuries (p=0.001) than other mechanisms. Older age and high grade of head injury severity resulted in poor outcomes (p=0.028 and p<0.001, respectively), and caused more accompanying chest/abdominal injuries (p<0.032 and p<0.001, respectively) compared with younger age and low grade of head injury severity. CONCLUSION: In bicycle-related head injuries, collision with motor vehicle is one of the most important risk factor for high grade of head injury severity and outcome. In addition, bicycle-related head injuries are often accompanied by injuries of other parts of the body.

Objective To understand the prevalence of unsafe riding practice among electric bicycle riders,and to provide scientific basis for intervention strategies in Ma'anshan city of Anhui Province.Methods Observational method was used to observe electric bicycle riders' behavior of running red light,wearing a helmet,and manned act.The radar speed measuring instrument was used to measure the speed of electric bicycle.Results The rate of electric bicycle riders' running red light was 13.09% (1 285/9 815),helmet wearing rate was 5.90% (1 510/25 576),and manned rate was 20.28% (5 187/25 576).The average speed was 24 ki/h,and the electric bicycles whose speed were > 20 km/h accounted for 74.60%.There were significant differences in the running red light rate,helmet wearing rate and the average speed of travel among different time periods and dates (all P < 0.05).More running the red light occurred during 13:30-14:30 and 15:00-16:00.Less helmet wearing occurred during 10:00-11:00 and 08:30-09:30.The periods with highest average speed were at07:00-08:00,08:30-09:30,11:30-12:30,and 13:30-14:30,which was 24 km/h.The helmet wearing rate of females (6.54%) was higher than that of males(5.46%),the men's average speed (24 km/h) was higher than women's (23 ki/h),and the differences were both statistically significant(all P < 0.001).Conclusion The electric bicycle riders in Ma'anshan city of Anhui Province have the dangerous behavior of running red lights,not wearing a helmet,manned act and speeding.Targeted interventions should be taken to reduce the occurrence of related risk behaviors.
ABSTRACT
Resumen A nivel mundial se registran anualmente alrededor de 3,308 víctimas de minas antipersonal (MAP), de las cuales un 67% corresponde a lesiones de miembros inferiores que requieren rehabilitación. Este artículo presenta un sistema de adquisición de datos para un equipo de rehabilitación de víctimas de MAP, quienes al interactuar con un videojuego de carreras de automóviles realizan la terapia. El sistema permite al terapeuta establecer una velocidad de pedaleo mínima y analizar la fuerza y velocidad del mismo. El desarrollo conceptual incorpora una bicicleta estática comercial, sensores para medir la fuerza de pedaleo, un sensor óptico para medir la velocidad y pulsadores de mando para interactuar con el videojuego. Para evaluar el sistema se caracterizaron y probaron los sensores, y se realizaron encuestas de percepción a 20 fisioterapeutas relacionadas con ergonomía, seguridad y potenciales beneficios del sistema. El 70%, 90% y 80% de los fisioterapeutas valoraron, respectivamente, estas características en un nivel Alto. Adicionalmente, al menos el 85% de ellos están de acuerdo con nueve beneficios potenciales para personas víctimas de MAP, por lo tanto se plantea que el sistema desarrollado puede utilizarse como 'juego serio' para apoyar las terapias de rehabilitación de personas con prótesis por esta causa.
Abstract Worldwide there are approximately 3,308 records of landmine victims during a year. 67% of them suffered injuries which require physical rehabilitation. This paper presents a data acquisition system for landmine victims rehabilitation, interfaced with a videogame, which enables to interact with a racing game. The therapist can set the minimum speed required for the rehabilitation and analyze the forces and speed developed while pedaling. The conceptual development incorporates a commercial static bicycle, sensors to measure the pedaling force, an optic sensor to measure the speed, and command buttons to control the videogame. In order to evaluate the system, the sensors were characterized and tested, and a survey was conducted to 20 physiotherapists in order to evaluate the perception of ergonomics, safety and possible benefits of the data acquisition system for rehabilitation of landmine victims. 70%, 90% and 80% of the physiotherapists, respectively, assessed these characteristics as High level. Moreover, at least 85% of them are agree with nine possible benefits for rehabilitation of landmine explosion victim. Therefore, it is proposed that the data acquisition system can be used as a serious game that supports rehabilitation therapies of people with a prosthesis due to this cause.
