ABSTRACT
Resumen: Objetivo: El objetivo del presente estudio fue evaluar los efectos de un programa escolar sobre la satisfacción de la competencia y la predisposición a participar en una Unidad Didáctica (UD) de bicicleta todo terreno (BTT) en Educación Física, así como el estado de la conducta de desplazarse en bicicleta. Método: Se realizó un diseño cuasiexperimental, sin grupo control, en el que participaron 98 estudiantes españoles (M=13.95±0.67; 50% chicas) de un centro educativo. El programa de intervención, basado en estrategias de apoyo a la competencia, consistió en una UD de BTT (12 sesiones), el plan de acción tutorial (4 sesiones) y una actividad extraescolar. Resultados: Se encontró un incremento en la satisfacción de competencia (únicamente en los chicos) y la predisposición hacia la UD de BTT en los dos géneros. Asimismo, se incrementó en un 39 % en los chicos y 43 % en las chicas, los estados de "Acción" y "Mantenimiento" en la conducta de desplazarse en bicicleta. Conclusión: Este programa multicomponente, basado en estrategias de apoyo a la competencia, parece ser efectivo para promover el desplazamiento activo en bicicleta entre los adolescentes.
Abstract: Objective: This study aimed to evaluate the effects of a school-based intervention program on competence satisfaction, the predisposition to participate in a cycling Didactic Unit (DU) in Physical Education, and the behavior of commuting by bicycle. Method: The study had a quasi-experimental design without a control group, in which 98 Spanish students (M=13.95±0.67; 50% girls) from a high school participated. The intervention program based on supporting competence consisted of a cycling DU (12 sessions), a tutorial action plan (4 sessions), and an extracurricular activity. Results: An increase in competence satisfaction was found only in boys, and the predisposition towards cycling DU was found in both genders. Likewise, the states of "Action" and "Maintenance" in the behavior of commuting by bicycle increased by 39% in boys and 43% in girls. Conclusion: This multi-component program based on strategies to support competence effectively promotes active bicycle commuting among adolescents.

ABSTRACT Different competitive environments appears to affect the physical demands during the sports competitions. Thus, the aim of this study was to report the mechanical demand and pacing behaviour of twelve male elite mountain bikers on cross-country short track (XCC) and cross-country Olympic (XCO). During both competition, total race time, speed, power output (PO) and cadence (CA) were recorded. As the race time in the XCC is shorter (21.0 ± 0.5 vs 84.0 ± 3.0 min; p<0.01), the average speed (26.6 ± 0.6 vs 17.8 ± 0.6 km/h; p<0.01), PO (365.0 ± 26.7 vs 301.0 ± 26.2 watts; p<0.01) and CA (81.2 ± 4.7 vs 77.4 ± 4.3 rev∙min−1; p=0.01) were higher than the XCO. While a variable pacing was adopted during XCC, a positive profile was adopted in XCO. In addition, athletes adopted a more conservative starting pace during XCC (below average race speed) but a faster start during XCO (above average race speed). These findings demonstrated that mechanical parameters and pacing profile adopted by cyclists are different between XCC and XCO. Therefore, mountain bikers and coaches must develop specific strategy and training methods in order to obtain success in each competition.
RESUMO Diferentes ambientes competitivos parecem afetar as demandas físicas durante as competições esportivas. Assim, o objetivo deste estudo foi reportar as demandas mecânicas e o comportamento do pacing de doze homens ciclistas de montanha da categoria elite durante o cross-country de pista curta (XCC) e o cross-country Olímpico (XCO). Durante ambas as competições, o tempo total de corrida, velocidade, potência (PO) e cadência (CA) foram gravados. Como o tempo de prova do XCC é menor (21,0±0,5 vs 84,0±3,0 min; p<0,01), a velocidade média (26,6±0,6 vs 17,8±0,6 km/h; p<0,01), PO (365,0±26,7 vs 301,0±26,2 watts; p<0,01) e CA (81,2±4,7 vs 77,4±4,3 rev∙min−1; p=0,01) foram maiores que no XCO. Enquanto um ritmo variável foi adotado no XCC, um perfil positivo foi adotado no XCO. Além disso, os atletas adotaram um ritmo inicial mais conservador durante o XCC (abaixo da velocidade média da prova), mas um início mais rápido durante o XCO (velocidade acima da média da prova). Esses achados demonstraram que os parâmetros mecânicos e o ritmo adotados pelos ciclistas são diferentes entre o XCC e XCO. Portanto, ciclistas e treinadores devem desenvolver estratégias e métodos de treinamento específicos para obter sucesso em cada competição.

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 Aims: Motocross consists of two races of 30 min with a break in between. Recovery between races is paramount to performance, this study aimed to compare the effects of active and passive recovery between motocross races on riding performance. Methods: Thirteen elite and non-elite racers performed two races of 30 min with 1 h break, twice with two-week interval. Between the races active (20 min ergometer cycling at 60% of HRmax) or passive recovery (no activity) were executed in a randomized order. Lap times, heart rate during riding, blood lactate, reaction time, handgrip strength, upper back pull strength, counter movement jump height, and medicine ball throw distance were measured before and after both races. Serum creatine kinase enzyme activity and strength tests were assessed also 24 h after the races. Results: No statistically significant differences were observed in any variables between protocols. A significant drop in handgrip strength was found post-race values (p < 0.001). Post-racing creatine kinase values were above resting levels. Conclusion: These results do not support the use of active recovery in between motocross races for restoration of neuromuscular or riding performance. Motocross seems to cause some exercise-induced muscle damage; thus, some rest is required to recover homeostasis.

Abstract Aims: This study aims to analyze the influence of adventure race disciplines on the overall performance during 35 to 50-km competitions. Methods: Twenty-four athletes from twelve teams were studied during the second (Jacarei-SP, Brazil, 44.5-km) and fourth (Passa Quatro-MG, Brazil, 37.1-km) races of the 2015 Haka Race Series, which comprised Brazilian Adventure Race Ranking. We analysed the relationship between disciplines velocities and overall race velocity of the teams during each competition. Results: We observed the race velocity of the teams during second race was significantly (P < 0.05) correlated with the first (R=0.80) and last (R=0.65) split velocities of trekking, and with the last split velocity of mountain biking (R=0.73). On the other hand, the race velocity of teams during fourth race was significantly (P < 0.05) correlated with the split velocity performed during the course of water trekking with trekking (R=0.96). Conclusion: Greater performance of the athletes in the disciplines of mountain biking, trekking and water trekking is related to their overall performance during 35-50 km ARs. In addition, the influence of adventure race disciplines is specific to the overall performance during different competitions.

The aim of this study was to identify the characteristics of the routes used for cycling according to gender on a sample of adolescents from the city of Curitiba, Brazil. The study was conducted in 2013 with 147 adolescents aged 12 to 17 years, who wore accelerometer and Global Positioning System receivers to assess physical activity and geographic locations. A total of 38 participants (50.0% girls) presented at least one bicycle route and were included in the analytic sample. A total of 386 routes were identified. Nearly all routes included public transportation facilities, plazas, and parcels with residential, retail, food or recreational land use (> 97.0%) while bike lanes/paths (62.7%) and Fitness Zones were less frequent (71.8%). Bus rapid transit (BRT) stations, parks and vacant lots were the least frequent feature in the routes (37.3%; 17.1%; and 7.5%, respectively). Routes used by girls had fewer vacant lots (3.9%; p = 0.001) and more residential, retail, food services, and recreational uses (99.6%; p = 0.003; 99.1%; p = 0.011; 98.7%; p = 0.030, respectively) than those used by boys. The findings suggest that the routes used by adolescents have mixed and diverse land use and girls ride along routes with greater bicycling and service infrastructure and less physical disorder than boys
O objetivo deste estudo foi identificar as características das rotas utilizadas para o uso de bicicleta de acordo com o sexo em uma amostra de adolescentes da cidade de Curitiba, Brasil. O estudo foi realizado em 2013 com 147 adolescentes de 12 a 17 anos, que usaram acelerômetro e receptores de Sistema de Posicionamento Global para avaliar a atividade física e a localização geográfica. Um total de 38 participantes (50,0% meninas) apresentaram pelo menos uma rota em bicicleta e, por isso, foram incluídos na amostra analítica. Foram identificadas 386 rotas. Quase todas as rotas incluíam meios de transporte público, praças e áreas residencial, comercial, de alimentos ou de lazer (> 97,0%), enquanto ciclovias (62,7%) e academias ao ar livre eram menos frequentes (71,8%). As estações de ônibus de transporte rápido (BRT), parques e terrenos vazios foram as menos frequentes nas rotas (37,3%; 17,1%; e 7,5%, respectivamente). As rotas utilizadas pelas me-ninas tiveram menos terrenos vazios (3,9%; p = 0,001) e mais residenciais, varejo, serviços de alimentação e recreação (99,6% ; p = 0,003; 99,1%; p = 0,011; 98,7%; p = 0,030, respectivamente) quando comparado com meninos. Os resultados sugerem que as rotas utilizadas pelos adolescentes têm uso misto e diversificado do solo e que meninas trafegam por rotas com maior infraestrutura de bicicleta e serviços e menos terrenos vazios quando comparado com meninos

Acanthamoeba keratitis (AK) is a rare sight-threatening corneal infection, often reporting from contact lens wearers. An asymptomatic human immunodeficiency virus (HIV)-infected Thai male without history of contact lens use complained foreign body sensation at his left eye during motorbike riding. He had neither specific keratitis symptoms nor common drugs responding, which contributed to delayed diagnosis. By corneal re-scraping, Acanthamoeba-like cysts were detected by calcofluor white staining and agar culture. The etiological agent obtained from the culture was molecularly confirmed by Acanthamoeba spp.-specific PCR, followed by DNA sequencing. The results from BLAST and phylogenetic analysis based on the DNA sequences, revealed that the pathogen was Acanthamoeba T4, the major genotype most frequently reported from clinical isolates. The infection was successfully treated with polyhexamethylene biguanide resulting in corneal scar. This appears the first reported AK case from a non-contact lens wearer with HIV infection in Thailand. Although AK is sporadic in developing countries, a role of free-living Acanthamoeba as an opportunistic pathogen should not be neglected. The report would increase awareness of AK, especially in the case presenting unspecific keratitis symptoms without clinical response to empirical antimicrobial therapy.

PURPOSE: As the usage rate of all-terrain vehicles (ATV) the number of injuries caused by ATVs is also surging. This has led to an increase in social attention to the safety of ATVs and the law for ATV safety standards was revised in 2009 and 2011. The purpose of this study was to evaluate the characteristics of ATV injury compared with motorbike injury after implementation of the ATV safety policy. METHODS: A retrospective cross-sectional observation study was conducted using emergent department (ED)-based indepth injury surveillance system data from 2011 January to 2014 December. Demographics, injury-related characteristics, injury severity, and outcomes of patients related to ATV and motorbike injury visiting our ED were analyzed. Multivariate logistic regression was used for major adverse event (MAE), which was defined as any intensive care, emergent operation, or death between ATV and motorbike related injury adjusted for covariates. RESULTS: During the study period, there were 101 ATV- and 584 motorbike-related injuries. Females had more ATV-related injuries (63.4% vs 32.9%, p<0.001) during leisure activities (93.1%) with higher helmet usage (73.3% vs 62.0%, p=0.01) and lower usage in terms of emergency medical service (23.8% vs 46.4%, p<0.001), automobile insurance (10.9% vs 54.1%, p<0.001) compared with motorbike-related injuries. MAE in ATV-related injuries was less likely in a univariate logistic model (unadjusted odd ratios [ORs] 0.489, 95% confidential intervals [Cis] 0.282 to 0.848), but the multivariate logistic model showed no significant difference (adjusted ORs 1.018, 95% CIs 0.376 to 1.414). CONCLUSION: Results of this study showed no significant difference in occurrence of clinical major adverse events between motorbikes and ATVs-related injury on Jeju Island. However, considering the high injury prevalence in young age, female, and passengers during leisure activities, development of an education and injury prevention program will be needed for this vulnerable population.

Road traffic injuries constitute 45% of deaths due to injury in Egypt. The aim of this cross-sectional study was to identify and investigate risky behaviours regarding road use among university students in Benha. A self-administered questionnaire was completed by 953 students. Of the respondents 19.3% reported not complying with pedestrian road traffic safety rules, while among drivers, 39.4% had no driving licence, 44.5% did not use a seat-belt and 63.5% exceeded the legal speed limits. In binary logistic regression analysis, substance use [OR 18.3; 95% CI: 9.10-23.3] and having peers with similar behaviours [OR 2.53; 96% CI: 1.15-5.55] were significant predictors of not following road traffic safety rules as a pedestrian. Exceeding the legal traffic speed limits as a driver was significantly associated with male sex [OR 5.13; 95% CI: 1.98-13.3], peer pressure [OR 8.70; 95% CI: 3.90-17.1] and substance use [OR 3.30; 95% CI: 1.58-13.7]. Unsafe road-use behaviours that may cause unintentional injuries are prevalent among University of Benha students. Health education sessions and training courses for students on appropriate road behaviours may be warranted

Road traffic injuries are major public health problems and a leading cause of death and injury around the world. Approximately 1.2 million people are killed each year in road crashes worldwide; with up to 50 million more injured. Over 95 of these deaths and injuries occur in the low- and middle-income countries of the world. The aim of this study is to evaluate the impact of the use of seat-belts in reducing the severity of injuries from road traffic crashes and to determine the compliance and awareness of the importance of the use of seat-belts among Nigerian motorists. Patients and Methods: The injury patterns and outcome of care in 140 patients who were seen at the emergency department of our tertiary hospital were evaluated. Initial care and resuscitation was carried out on all patients using the advanced trauma life support protocol. Results: A total of 81 (57) patients used seat-belts; while 59 (42.1) did not. Nineteen (13.6) patients died as a result of their injuries; 4 (21.1) of these had used seat-belts; while 15 (79) had not ( P = 0.001). The mortality rate of 79 for patients who did not use seat-belt was statistically significant. Conclusions: The seat-belt is an effective safety tool that not only saves lives; but also significantly reduces the severity of the injury that a vehicle occupant may have sustained if they were not wearing the device. More public enlightenment is needed to increase the awareness and compliance of use of seat-belts among Nigerian motorists. for patients who did not use seat-belt was statistically significant. Conclusions: The seat-belt is an effective safety tool that not only saves lives; but also significantly reduces the severity of the injury that a vehicle occupant may have sustained if they were not wearing the device.

OBJECTIVE: Traumatic epidural hematomas (EDHs) in children are a relatively unusual occurrence. The cause and outcome vary depending on period and region of study. The aims of this analysis were to review the cause and outcome of pediatric EDHs nowadays and to discuss outcome-related variables in a large consecutive series of surgically treated EDH in children. METHODS: This is a retrospective review of 29 patients with surgically treated EDHs between Jan 2000 and February 2010. Patients' medical records, computed tomographic (CT) scans, and, if performed, magnetic resonance imaging (MRI) were reviewed to define variables associated with outcome. Variables included in the analysis were age, associated severe extracranial injury, abnormal pupillary response, hematoma thickness, severity of head injury (Glasgow Coma Scale score), parenchymal brain injury, and diffuse axonal injury. RESULTS: The mean (SD) age of the patients was 109 months (0-185 months). Most of the injuries with EDHs occurred in traffic accident (14 cases, 48.2%) and followed by slip down in 6 cases and falls in 6 cases. There were one birth injury and one unknown cause. EDHs in traffic accidents occurred in pedestrians hit by a motor vehicle, 9 cases; motorbike and car accidents, 5 cases and bicycle accidents, 1 case. The locations of hematoma were almost same in both sides (left side in 15 cases). Temporal lobe is the most common site of hematomas (13 cases, 44%). The mean size of the EDHs was 18 mm (range, 5-40 mm). Heterogeneous hematomas in CT scans were 20 cases (67%). Two patients were referred with unilateral or bilateral dilated pupil(s). There was enlargement of EDH in 5 patients (17%). All of them were heterogeneous hematomas in CT scans. Except for 4 patients, all EDHs were associated with skull fracture(s) (87%). There was no case of patient with major organ injury. CT or MRI revealed brain contusion in 5 patients, and diffuse axonal injury in one patient. The mortality was zero, and the outcomes were excellent in 26 and good in 2 patients. None of the tested variables were found to have a prognostic relevance. CONCLUSION: Regardless of the EDH size, the clinical status of the patients, the abnormal pupillary findings, or the cause of injury, the outcome and prognosis of the patients with EDH were excellent.
