Supercross is characterized by fast and skillful movements, with high concentration being required on an indoor competition circuit, due to the demanding jumps and short distances to the next ...obstacle. The injuries can turn out to be diverse, including polytraumatization. This paper aims to evaluate the accidents and possible injuries in a single Supercross competition. To what extent is the presence of medical staff required?
During the 17th International Supercross Event in Chemnitz, 93 participants started in 5 classes. Severe injuries were treated at the track, through the emergency department and hospital stay to their discharge.
Overall 5 participants (4.65%) had to be admitted to the clinic:
Injuries from risky jumps at relatively high speed can range from minor contusions to fractures and serious injuries. The permanent readiness of medical staff and emergency doctors at the site is therefore justified and required. The variety of injuries in a Supercross event can affect the head and face, the upper- and lower extremities, thoracal- and abdominal traumas and especially the spine. In addition, a special training concept in terms of preventive measures to prevent falls would be desirable.
Pediatric oncology integrative medicine is a growing field which needs further dedicated studies to expand the general awareness about the role of integrative therapies in mitigating the pediatric ...oncology experience. The present study intended to discover the potential of an innovative approach known as Freestyle Motocross Therapy (FMX Therapy) to support hospitalized pediatric cancer patients, their parents and doctor-nurse professionals. The specific aim was to explore if the quality of their oncology experience improved after FMX Therapy.
This was a pre-post interventional study involving 50 pediatric patients with oncological disease (average age 9.2; 43 % male; 73 % leukemia diagnosis), 50 parents (average age 33.2; 83 % female) and 25 doctor-nurse professionals (95 % female).
The self-report questionnaire was completed by children/adolescents, parents and professionals before (Time 0) and after (Time 1) FMX Therapy, to assess several health outcome measures (e.g., pain, stress).
After therapy, results showed a reduction in the average perception of pain in children/adolescents (Time 0 = 3.34 vs Time 1 = 1.66, p < .0001) and in the average perception of stress in parents (Time 0 = 6.92 vs Time 1 = 4.06, p < .0001). For both patients and parents, there was an increase in positive emotions and a reduction in negative emotions after FMX Therapy. Doctor-nurse professionals also highlighted the positive effects of FMX Therapy.
FMX Therapy improves the pediatric oncology experience, and it appears to have all the features to be considered a nascent field with great potential as integrative medicine for patients, parents and professionals.
Purpose
The purpose of this study is to report the spectrum of injuries sustained by competitive paediatric motocross athletes at a level I trauma centre.
Patients and Methods
A retrospective study ...of paediatric competitive motocross injuries treated at a level I trauma centre between 2004 and 2014 was performed. Athletes were included if aged less than 18 years and injured while practising or competing on a competitive motocross track. Medical records were reviewed for age, gender, race, location of accident, use of safety equipment, mechanism of injury, injury type and severity, Glasgow Coma Score at hospital presentation and Injury Severity Score (ISS).
Results
In total, 35 athletes were studied. The average age was 14 years. One athlete died. Thirty athletes were injured during competition; five were injured during practice. Twenty-four athletes (69%) suffered an orthopaedic injury with a total of 32 fractures and two dislocations. Two fractures were open (6.3%). Lower extremity fractures were twice as common as upper extremity fractures. Surgery was more common for lower extremity fractures—83% versus 30%. The most common fractures were femoral shaft (18.8%), fibula (12.5%), clavicle (12.5%), tibial shaft (9.4%) and forearm (9.4%).
Conclusions
Competitive paediatric motocross athletes suffer serious, potentially life-threatening injuries despite the required use of protective safety equipment. Femoral shaft, fibula and clavicle were found to be the most commonly fractured bones. Further prospective research into track regulations, protective equipment and course design may reduce the trauma burden in this athlete population.
PurposeThe purpose of this study is to examine the theoretical relationship between experience quality (EXQ), satisfaction and the behavioral intentions (BI) of Motocross World Championship ...spectators.Design/methodology/approachThe research data were collected from spectators who participated in the World Motocross Championship race held in Afyon, Turkey in 2018. The structural equation model (SEM) was used to test the relationship among the research variables.FindingsThe results showed EXQ had significant and direct effects on satisfaction and BI. In addition to this, satisfaction had a partial mediating effect between EXQ and BI.Originality/valueTo date there has been no empirical study examining the consumer behaviors of motocross event spectators. Consequently, this research provides important contributions to the literature and informs event organizers about the role of EXQ in terms of understanding the behavior of motocross event spectators.
Objective
Off‐road riding of quad bikes and motorcycles is common among children across rural and remote Australia, but is a significant source of injury and hospitalisation. An in‐depth analysis of ...paediatric off‐road vehicle crashes was undertaken to inform injury prevention countermeasures by characterising injury patterns and sources of injury.
Design
This is a prospective in‐depth case series.
Participants
Participants are children aged 16 and under who have been hospitalised due to injury sustained from the use of an off‐road motorcycle or quad bike in New South Wales, Australia.
Interventions
Crash investigation techniques (medical data, structured interview, vehicle and crash site inspection) were used to ascertain details of the crash event, protective gear, injury information and contributory factors.
Results
Thirty children were recruited, 27 boys and 3 girls, ranging in age from 4 to 16 years, having crashed on off‐road motorcycles (n = 27) or quads (n = 3). Most (73.3%) were participating in unstructured social riding. A total of 67 separate injuries were observed, with overall Injury Severity Scores between 1 and 35. There were high rates of wearing helmets and motorcycle‐specific garments. The most commonly injured areas were the upper and lower extremities. The most common sources of injury were from impacting the ground, obstacles/other riders or the vehicle.
Conclusion
This study demonstrates the patterns of riding and injury in rural paediatric off‐road vehicle riders, occurring despite high rates of helmet/protective gear use. This underscores the need for investigation into the injury mitigation and fit properties of protective gear and the inherent risks for physically and developmentally maturing children.
The aims of this study were to analyse the optimal cadence for peak power production and time to peak power in bicycle motocross (BMX) riders. Six male elite BMX riders volunteered for the study. ...Each rider completed 3 maximal sprints at a cadence of 80, 100, 120 and 140 revs · min

The results indicate that the optimal cadence for producing peak power output and reducing the time to peak power output are attained at comparatively low cadences for sprint cycling events. These findings could potentially inform strength and conditioning training to maximise dynamic force production and enable coaches to select optimal gear ratios.
The aim of this study was to ascertain the variation in elite male bicycle motocross (BMX) cyclists' peak power, torque, and time of power production during laboratory and field-based testing. Eight ...elite male BMX riders volunteered for the study, and each rider completed 3 maximal sprints using both a Schoberer Rad Messtechnik (SRM) ergometer in the laboratory and a portable SRM power meter on an Olympic standard indoor BMX track. The results revealed a significantly higher peak power (p ≤ 0.001, 34 ± 9%) and reduced time of power production (p ≤ 0.001, 105 ± 24%) in the field tests when compared with laboratory-derived values. Torque was also reported to be lower in the laboratory tests but not to an accepted level of significance (p = 0.182, 6 ± 8%). These results suggest that field-based testing may be a more effective and accurate measure of a BMX rider's peak power, torque, and time of power production.
