Arm Pump is a well known phenomena in the motocross. It causes pain in the arm due to a compression and is a common disorder among even skilled motocrossers. The etiology of this pain is not well ...understood although it may be related to excessive muscle tension and inappropriate posture. Most likely the pain is the result of dysponesis in which the motocross cyclist does not relax the muscles. This single case report demonstrates the use SEMG for diagnosis and development a successful clinical intervention. The subject was a 16 year old male who experienced severe pain after 10 min of riding. In the office, SEMG was recorded from the extensors of the underarm muscles while mentally rehearsing riding his motorbike. In the simulation, the EMG showed high activity (up to 40 pV) in the underarm muscles, as long as he was thinking of riding his motorbike. The SEMG training protocol consisted on teaching microbreaks (a 1 s epoch in which the SEMG decreased to 2-5 pV) while mentally riding. After 10 min of SEMG training he was able to make small microbreaks. The post SEMG recording with an imagery riding of the same circuit, showed a significant decrease in SEMG and numerous microbreaks. The second therapeutic session was at the actual motocross circuit where corrections of posture and arm position on the motorbike were given. Using appropriate language cues such as "feel the weight in your arms" facilitated relaxing of the muscles during the actual circuit riding. After these two interventions, he was able to drive for more than 2 h without any complaint. The rapid decrease in symptoms occurred most likely because of the dynamic relationship between the body posture and the motocross cycle. Combining mirror, photo and SEMG feedback demonstrated how to sit in an appropriate position on the bike as well as perform microbreaks. This case report suggests that changes in SEMG and body posture training should be used as a possible treatment and preventative approach for Arm Pump symptoms. Adapting this approach to sport specific symptoms may eliminate symptoms and improve performance. Keywords * SEMG * Arm Pump by Motocross * Peak performance
The purpose of the study is to justify the methods of special physical training of athletes in motocross on motorcycles with a side trailer, taking into account their individual characteristics. ...Research objectives: To develop a methodology for training athletes specializing in motocross motorcycles with a sidecar, taking into account the specific interaction of crew members. Material and research methods: a pedagogical experiment was organized in order to compare the technical and tactical indicators of the competitive activity of world leaders and leading Ukrainian crews in cross-country motorcycle riding with wheelchairs, and justification, on this basis, of methodological recommendations for preparing our athletes for participation in international competitions the highest level. Results apparent difference in the speed of the distance between world and Ukrainian leaders indicates a significantly higher level of special, functional and technical preparedness of the former, which at higher speeds overcome obstacles at a distance, demonstrating a high level of universality of their preparedness. It has been revealed that the special physical training of our athletes is a reliable reserve for increasing their sports performance.Conclusions. Application of the methodology for constructing a qualitative structure of competitive motor activity of athletes in cross-country on motorcycles with heelchairs made it possible to stablish that the leading motor quality is special agility. The second most important in ensuring a high sports result in cross-country on motorcycles with wheelchairs is the general and special endurance of crew members.
Musculoskeletal injuries often occur when performing motocross; almost half of the overall ligamentous injuries (42%) are knee ligaments injuries. Lesions can be greatly reduced with knee braces. ...Commercial knee braces are expected to oppose and limit unwanted and potentially harmful movements such as hyperextension and excessive rotation of the knee joint. However, this aspect has not been fully investigated from a biomechanical point of view. This would require proper Finite Element Modelling (FEM) and Analysis (FEA). However, to perform FEA and evaluate the efficacy of the brace simulating sportive conditions, numerical models need to be built. It requires a dedicated setup and several preprocessing steps, for which no industrial standard or widely accepted better practise is available as of today. Firstly, the brace and the lower limb are scanned using a 3D scanner. The geometry is reconstructed using reverse engineering techniques. These allow us to obtain a smooth, reliable 3D model starting from the points cloud acquired during scanning. A lower limb model was created using a mixed approach, combining MRI data and 3D scanning. Finally, a simulation of the impact condition after a jump using the developed model was carried out.
Background: Motocross is one of the most popular motorized off-road sports, characterized by riding on irregular natural terrain of hard earth and/or sand with various obstacles throughout the ...course. Objectives: This study evaluated the influence of a motocross training session on neuromuscular response and blood lactate in amateur riders. Patients and Methods: Nine motocross riders (22.7 ± 2.8 years) participating in amateur competitions at the state level conducted a training session of 20 minutes duration at a motocross track (1.6 km) with a 250-cc four-stroke motorcycle. Metabolic demand was measured with blood lactate concentrations before and immediately, 3, 5, 8, and 10 minutes after the training session. To measure neuromuscular response, riders completed handgrip strength and horizontal jump tests before and 10 minutes after the training session. Student's t-test and analysis of variance one-way repeated measures were used to compare the changes before and after the motocross training session. Results: Significant decreases in handgrip strength were observed for both hands (left: P= 0.010 and right: P = 0.004). However, no significant difference (P= 0.241) in horizontal jump ability was observed. Significant blood lactate values were observed immediately (P= 0.001), 3 (P= 0.001), 5 (P= 0.001), and 8 (P = 0.01) minutes after training when compared to the value before training. The peak blood lactate value was 6.5 ± 2.7 mMat 8 minutes after the training session. Conclusions: Amateur motocross riders had significant anaerobic metabolism demands and had reduced handgrip strength following a training session. These data suggest an importance of physical training aimed at improving anaerobic and neuromuscular performance of the upper limbs in amateur motocross riders. Keywords: Lactate, Metabolism, limbs
Applications in Sport: A clear understanding of why athletes decide to wear or not wear neck braces in motocross would help various stakeholders identify barriers to device use, develop better ...methods for encouraging its adoption, and improve the overall safety of athletes participating in the popular but understudied sport.
