‘Downhill race for a rainbow jersey’: the epidemiology of injuries in downhill mountain biking at the 2023 UCI cycling world championships—a prospective cohort study of 230 elite cyclists

ObjectivesThis study aims to understand the prevalence, incidence rate, anatomical sites, injury severity and main medical actions carried out during official training and racing by elite downhill mountain biking (DHMTB)...

Recreational athletes during downhill-mountain biking (DMB) show high incidence of upper extremity fractures in combination with soft-tissue injuries

Downhill-mountain biking (DMB) is a high-risk sport and often leads to several injuries, especially in non-professional athletes. We retrospectively analyzed the most common injuries and profiled the injury mechanism. Until now, there is no such analysis of injuries by non-professional mountain bike athletes. We collected patient data from patients who suffered from an injury during DMB. The inclusion criteria were (1) injury during the summer season of 2020 and 2021, (2) injury during off-road and downhill mountain bike sports activity, and (3) treatment at the Department of Traumatology of the Klinik Diakonissen Schladming. Patient data was analyzed regarding the type of injury, location of the injury, patient age and gender of the patients. Most patients with injury are at the age of 26–35. Second most are between 36 and 71 years old. The type of injury differs between age and gender. Mostly upper-extremity injuries occur with a high probability of shoulder injuries. In the elderly patients, we found additional injuries of the thorax and chest. To conclude, most common types of injuries are soft-tissue injuries, often in combination with fractures. The risk for injuries is higher for recreational athletes with different injury characteristics than professional athletes.

Starting in your mental pole position: hypnosis helps elite downhill Mountainbike athletes to reach their optimal racing mindset.

Downhill Mountain Biking is an extreme sport requiring high mental strength to perform on the best level in a competition with only one run to win the race. The substantial challenge here is to control automatic processes like competitive anxiety and stress. Hypnosis can address these automatic processes. We developed and evaluated a hypnosis audio-intervention to activate the optimal racing mindset. In our study, 19 elite Downhill Mountainbike athletes registered at two consecutive races of the IXS Downhill Cup. After the first race, athletes listened to the hypnosis audio-intervention. In this intervention, we instructed the athletes how to activate their optimal mental state before the second race. At both races, we measured competitive anxiety, stress, self-confidence, state resilience, and flow with validated questionnaires and assessed resting heart rate variability as physiological measure of resilience. Race-related somatic anxiety and subjective stress decreased significantly while self-confidence increased significantly from first to second race after athletes listened to the hypnosis. Heart rate variability was significantly increased at the second race indicating elevated vagal activity. When comparing race results of our participants to a control group of other elite athletes competing in the races but not listening to the hypnosis, we found that our study participants generally performed better in both races. The study shows that our hypnosis intervention was effective in reducing competitive anxiety and stress while increasing perceived resilience and self-confidence: After a self-administered hypnosis session, athletes were able to improve automatic processes responsible for putting them in their mental pole position.

Flow and outdoor adventure recreation: Using flow measures to re-examine motives for participation

Adventure participants have traditionally been viewed as having thrill or risk-seeking motives, and this perception remains despite empirical research suggesting that other motives may drive participation. This study was conducted to extend understanding of participation motives of adventure recreation participants in relation to Csiksentmihalyi’s nine-dimension model of flow and other proposed motivational constructs. Participants (n = 199) who had typically engaged in their adventure recreation activity (i.e., highlining, rock climbing, downhill mountain biking, freefalling, snow sports) regularly, and with considerable competence, took part in this investigation by completing self-report measures of dispositional flow (The Dispositional Flow Scale; DFS-2), state flow (The Short Flow State Scale; SFSS), and participation motives in their adventure recreation environments. Support was observed in confirmatory factor analytic procedures for the factorial validity of DFS-2 and SFSS data obtained from adventure recreation participants. Mean scores from measures on participant experience of flow in adventure recreation were generally found to be significantly higher than previously observed in other physical activity domains, with some differences also being observed among adventure recreation subgroups. Contrary to traditional explanations of adventure recreation participation, risk-seeking was not supported as a key underlying motive by participants in this study. Mastery of one’s adventure recreation activity, perceived connection to one’s activity, and trust in one’s skills, were identified as important participation motives. This study demonstrated that the DFS-2 and SFSS were able to satisfactorily assess flow constructs in adventure recreation, and supported recent research demonstrating flow to be a relevant experience to this setting. The implications of these findings for theory, practice, and future research directions in adventure recreation are discussed.

Reattachment of Fractured Tooth Fragment by Multidisciplinary Treatment Approach.

Dental anterior fractures are common injuries, especially in those who practice extreme sports. This report describes a 25-year-old Bolivian patient who attended our private dental clinic in La Paz, Bolivia after experiencing an accident during downhill mountain biking. An intraoral examination revealed a fracture line on the buccal side in the middle third of the coronal portion of the right central maxillary incisor which extended towards the proximal and lingual sides. Multidisciplinary treatment, including crown lengthening, osteotomy, root canal treatment, fiberglass post insertion, and reattachment of the fracture segment was performed. A follow-up examination at 10 months later revealed that the tooth was completely reestablished both functionally and esthetically and that there was no periapical pathosis or discomfort. This outcome suggests that if a patient seeks a dental consultation soon after a complex crown-root fracture has occurred, and if the broken tooth segment is available, then reattachment offers an economical and simple treatment option which will allow immediate restoration of functionality and esthetic standards. Continued follow-up should form part of such a treatment plan to allow long-term pulp vitality and periodontal health status to be monitored.

'It's All Downhill from Here': A Scoping Review of Sports-Related Concussion (SRC) Protocols in Downhill Mountain Biking (DHI), with Recommendations for SRC Policy in Professional DMB.

Introduction: Downhill mountain biking (DHI) is a form of cycling and does not currently have a specific sports-related concussion (SRC) assessment. Objective: To review the extent, range and nature of research investigating SRC in DMB, provide a summary of key literature findings relating to its identification and management, and then develop a SRC protocol specific to DMB. Design: Scoping review as per recognised methods. Setting: Literature-based. The following databases were searched: MEDLINE, EMBASE, Scopus and Web of Science, with no restrictions on date. Results were limited to the English language. Participants: Six articles were included in the review from 64 identified articles. The article had to specifically include an analysis of adult downhill riders for inclusion. Outcome measures: Study type, study group (amateur/professional), concussion incidence, concussion assessment and recommendations. Main Results: Concussion incidence was identified as between 5–23%. No study outlined a trackside assessment of cyclists or a protocol for return to play where SRC was identified. Several authors identified that riders often continued to participate despite the presence of a concussion. No sport-specific SRC assessment was determined for DHI, and a SRC assessment was therefore developed. Conclusions: This review illustrates the lack of studies and formal protocol in SRC assessment for DHI. In light of this, we propose a three-stage framework specific to the sport to best identify a concussion and act where appropriate while minimising disruption to competition. This framework involves assessing the cyclist on the ‘sideline’, a second assessment post-event in the medical room and a third assessment the following day. A SRC consensus meeting specific for DHI is suggested with an identified need for updated guidance from UCI, requiring possible rule changes for the sport.

Multiple Motives for Adventure Sport Revisited: A Multi-Activity Investigation

The growing popularity of adventure recreation highlights the need to understand its participants and the individual characteristics of these activities in order to target health and well-being outcomes through adventure leisure pursuits. While exploratory qualitative studies have questioned the centrality of risk and thrill in adventure recreation, these studies often involved small sample sizes and amalgamated diverse adventure activities. The current study investigated adventure recreation motives via semi-structured interviews with a large sample (n = 84) of expert participants across six distinct air, land and water-based adventure activities (e.g., wingsuit BASE jumping, freeriding, downhill mountain biking, big-wave surfing). Seven themes (underpinned by 12 subthemes) emerged during thematic data analysis as key adventure recreation motives: holistic living, emotional diversity, competence, social connectedness, nature experience, agency, and optimal mental states. Although all themes were present across each adventure activity, data illustrated differences in the relative importance of motives across activities. Findings suggested that (1) adventure recreation and associated motives are more heterogeneous than currently conceptualized, and (2) adventure recreation motives should be more broadly conceptualized beyond hedonic motives (e.g., risk and thrill-seeking) to encompass more diverse eudaimonic motives.

Assessment of the mean erosion rate using dendrogeomorphological approaches on exposed roots along hiking and biking trails in the Bucegi Mountains, Romanian Carpathians

Mountain hiking and biking trails are important components of the tourism infrastructure, represent opportunities for recreation, and form a network that prevents uncontrolled tourist dispersion. The erosion processes accelerate under tourist impact in the forested mountains, revealing exposed roots.The aim of our study was to estimate the mean erosion rates along two hiking trails and one mountain biking trail in the Bucegi Mountains, using dendrogeomorphological approaches.The three trails used were: Sinaia town – Cota 1400 hiking trail (SHT), Sinaia biking trail (SBT), a downhill mountain biking trail and Buşteni town – Urlătoarea Waterfall hiking trail (UHT). The following results were obtained. The mean erosion rate along SHT was between 1.7 and 19.6 mm • y−1 with an average of 6.4 ± 4.6 mm • y−1, wherein half the cases showed an erosion rate between 1 and 5 mm • y−1. The mean erosion rate along SBT was between 2.6 and 49.4 mm • y−1, with an average of 24.2 ± 14.4 mm • y−1. Values between 1 and 20 mm • y−1 represent 41.9% and the remaining 58.1% comprise values between 20 and 40 mm • y−1 or even exceeding 40 mm • y−1. In the case of UHT, the mean erosion rate was between 3.5 and 36 mm • y−1, with an average of 14 ± 8.1 mm • y−1.The differences in values between these three trails are represented in terms of trail usage time, type of use, hiking versus biking during the hot season, and the age of roots. Our study highlighted that the forested mountain environment is sensitive to tourist impact while also proving that the dendrogeomorphological approach is a useful tool for evaluating the mean erosion rates of trails based on the exposed roots.

Extreme Sport: Understanding the Concept, Recognizing the Value

Extreme sport is one of the fastest-growing areas in sporting activity in this century. Extreme sport appears to be used interchangeably with high-risk sport in much of the research literature. Both high-risk sport and extreme sport are defined as any sport where one has to accept a possibility of severe injury or death as an inherent part of the activity. Extreme sports are rapidly becoming the physical activity of choice. Extreme sports have diffused around the world at a phenomenal rate and far faster than established sports. Commercially, extreme is the password for corporations and advertisers to access young population. Extreme sports increasingly attract participants from different social classes and age groups, as well as females and minority groups. The extreme sport comprises tourist activities, therapeutic activities, recreational activities, and sporting activities. They have become a sporting spectacle. Extreme sports are even discussed in marketing (niche market), management, and policy literature as legitimate niches that require their peculiar understanding or inappropriate activities that need to be banned. Adventure and risk-taking sports such as mountaineering, whitewater rafting, surfing, skiing, skydiving, downhill mountain biking, rock climbing, and BASE (Building, Antenna (or Aerial), Span (i.e., bridge), Earth (cliffs or other rock formations)) have increased in popularity in recent years. This study is an overview of previous studies carried out by eminent scholars of psychology and different disciplines. The objective of this study is to understand extreme sport in better way on one side and how extreme (or adventurous) sport has been theoretically conceptualized and re-conceptualized on the other. The researcher made an effort to disseminate the knowledge of extreme sports to the students, researchers, entrepreneurs, media personnel, and other concerned authorities, related organizations, and institutions. It is also believed that this study will help to promote adventure education, adventure tourism (niche tourism) and deep ecology. The participants strongly believe that the natural world acts as a facilitator to a deeper, more positive understanding of self and its place in the environment. Fear, emotion, stress, risk, uncertainty, motivation, wellness, wellbeing, personality traits and determination are the key elements of extreme sports.

Does participation in Downhill mountain biking affect measures of executive function?

This study assessed the influence of downhill mountain biking on acute measures of executive function. Twenty-three participants took part in the study and were assigned to either, FIELD (N=7, mean age 27 ± 9 yrs), LAB (N=8, mean age 36 ± 9 yrs) or CONTROL (N=8, mean age 41 ± 9 yrs) groups. Participants performed the Stroop colour-word test via a tablet pc app (EncephalApp). Additionally, the Trail Making Test A (TMT-A) and B (TMT-B) were completed. Significant main effects were found for OffTime (F2,12 = 13.04; p = .001; ηp2 = .69), OnTime (F2,12 = 4.31; p = .04; ηp2 = .42) and OnTrials (F2,12 = 10.74; p = .002; ηp2 = .64), with the results showing a decrement in Stroop test performance following Trial1 and Trial4 compared to BL for the FIELD group. A significant main effect was found for TMT-A (F2,12 = 7.50; p = .008; ηp2 = .56), with performance improving following Trial4 compared to BL for the FIELD group. LAB and CONTROL groups significantly improved on the TMT-B from BL to Trial1 and Trial4 (F2,14 = 4.31; p = .04; ηp2 = .38 and F2,14 = 13.70; p = .001; ηp2 = .66, respectively). Results suggest participation in downhill mountain biking in this cohort significantly impaired executive function when compared to repeated sprint activity within a laboratory. This is indicative of repeated head accelerations caused by riding over rough terrain.

The Thrill of Speedy Descents: A Pilot Study on Differences in Facially Expressed Online Emotions and Retrospective Measures of Emotions During a Downhill Mountain-Bike Descent

When extreme sport athletes explain the engagement behind their taxing and risky endeavors, they often refer to the happiness generated by the activities. However, during the activity, these athletes seem neither pleased nor happy. This article proposes some answers from a study of facially expressed emotions measured moment by moment during downhill mountain biking. Self-reported emotions were also assessed immediately after the trip was over. The participants display less happiness during the activity than before and after the activity. No significant associations between facially expressed and self-reported emotions were observed. Findings are discussed with reference to the functional well-being approach arguing that some momentary feelings are non-evaluative in the sense of being caused by the difficulty of the ongoing activity. Within this framework, easy tasks produce happy feelings while difficult tasks produce interest—regardless of whether a goal has been reached or not. By contrast, retrospective emotions involve the evaluation of the activity in relation to its goal. When a goal is accomplished, the accompanying feeling is positive. If a goal (or value) is threatened, lost, or not achieved, negative feelings follow.

Why Do You Ride?: A Characterization of Mountain Bikers, Their Engagement Methods, and Perceived Links to Mental Health and Well-Being.

Mountain biking is an increasingly popular outdoor activity on the extreme sport continuum. Extreme and high-risk sports have been investigated using a variety of motivational theories with sensation seeking a dominant theme; however, behavioral and motivational homogeneity within these types of populations should not be assumed. Recent studies have highlighted the therapeutic potential of extreme sports and similar outdoor activities. The aim of this study was to describe the characteristics of mountain biking participants, their engagement methods, and perceived benefits to mental health and well-being. This was a cross-sectional survey and participants were recruited via social media. An online questionnaire specific to the domain of mountain biking was developed. Analysis of the full sample (n = 1,484) and of three independent paired sub-samples was conducted using SPSS. The sub-samples compared the results of males and females; younger and older riders; and those who have recently engaged in downhill mountain biking and those who have not. The results have succeeded in identifying some disparities in mountain biker characteristics and engagement methods. The results suggest that some riders found pleasure in higher risk engagement. The study proposes various explanations for the disproportion of women in mountain biking. Irrespective of the confounding factors related to rider characteristics or engagement methods, mountain bikers reported copious benefits to mental health and well-being related to their engagement. There was a high reported usage of mountain biking as a coping strategy. As such, this study provides insights that could inform the development of outdoor activities as interventions for mental health.

The magnitude of translational and rotational head accelerations experienced by riders during downhill mountain biking

ObjectivesTo determine the magnitude of translational and rotational head accelerations during downhill mountain biking. DesignObservational study. MethodsSixteen male downhill cyclists (age 26.4±8.4years; stature 179.4±7.2cm; mass 75.3±5.9kg) were monitored during two rounds of the British Downhill Series. Riders performed two runs on each course wearing a triaxial accelerometer behind the right ear. The means of the two runs for each course were used to determine differences between courses for mean and maximum peak translational (g) and rotational accelerations (rad/s2) and impact duration for each course. ResultsSignificant differences (p<0.05) were revealed for the mean number of impacts (>10g), FW=12.5±7.6, RYF=42.8±27.4 (t(22.96)=−4.70; p<0.001; 95% CI=17.00 to 43.64); maximum peak rotational acceleration, FW=6805.4±3073.8rad/s2, RYF=9799.9±3381.7rad/s2 (t(32)=−2.636; p=0.01; 95% CI=680.31 to 5308.38); mean acceleration duration FW=4.7±1.2ms, RYF=6.5±1.4ms (t(32)=−4.05; p<0.001; 95% CI=0.91 to 2.76) and maximum acceleration duration, FW=11.6±4.5ms, RYF=21.2±9.1 (t(29.51)=−4.06; p=0.001; 95% CI=4.21 to 14.94). No other significant differences were found. ConclusionsFindings indicate that downhill riders may be at risk of sustaining traumatic brain injuries and course design influences the number and magnitude of accelerations.

The influence of repeated chin bar impacts on the protective properties of full-face mountain biking helmets

Full-face helmets are designed to protect against head and face injuries during downhill and free-ride mountain biking. This study assessed whether multiple impacts and helmet type are related to the protective properties of full-face helmets. A drop tower fitted with a helmeted headform simulated impacts to the chin following a forwards fall. Four models of full-face mountain biking helmets were tested. Three repeated trials were completed for each helmet at four impact velocities. Outcome variables included head injury criterion score, peak force, and peak acceleration. Peak accelerations for all trials were below the 300 g pass/fail criterion used in some testing standards. Multiple impacts reduced helmet protective properties, most noticeably at the higher impact velocities (increases in impact severity measures ranging from 11% to 22% for low and 17% to 49% for higher impact velocities). However, the effects of multiple impacts were smaller than the differences observed across individual helmet types. Helmet protective properties were associated with local chin bar characteristics, most notably chin bar length at higher impact velocities. Towards the goal of reducing overall head/brain injury risk in cyclists, there may be value in complimentary messaging about the importance of repeated impacts and helmet type on the protective properties of downhill mountain biking helmets.

Vertigo in downhill mountain biking and road cycling

Vertigo has been described after the practice of mountain bike. This study aimed to investigate the prevalence of vertigo following competitions or training sessions of downhill mountain biking (DMB) or road cycling (RC). One hundred and two DMB riders, 79 road cyclists and 73 control participants filled in a survey intended to evaluate the prevalence of vertigo in daily living activities and following competitions or training sessions. Vertigo causal factors (crashes, head trauma, fatigue, characteristics of the path/road ridden) were recorded. DMB riders and road cyclists did not report more vertigo during daily living activities than controls. But DMB riders older than 30 had more risk to report vertigo than age-matched road cyclists (OR: 5.06, 95% CI: 1.23–20.62). Road cyclists aged between 20 and 29 were 2.59-fold (95% CI: 1.06–6.27) more likely to report vertigo than controls. After competitions and training sessions, DMB riders were 2.33-fold (95% CI: 1.22–4.41) more likely to report vertigo than road cyclists. Vertigo causal factors were crash with head trauma in DMB riders and fatigue in road cyclists. Vertigo during daily living activities may be of concern for cyclists, particularly older DMB riders. The accumulation of impacts (crashes, vibrations) during the career of a DMB rider may generate micro-traumatisms of the central nervous system and/or peripheral vestibular structures, particularly the otolith organs. In RC, the pathophysiological mechanisms generating vertigo might be effort-related disturbance of homeostasis. To avoid injuries, DMB riders should be aware that vertigo may occur at the end of training sessions or competitions.

Characteristics Explaining Performance in Downhill Mountain Biking

To identify physiological, psychological, and skill characteristics that explain performance in downhill (DH) mountain-bike racing. Four studies were used to (1) identify factors potentially contributing to DH performance (using an expert focus group), (2) develop and validate a measure of rider skill (using video analysis and expert judge evaluation), (3) evaluate whether physiological, psychological, and skill variables contribute to performance at a DH competition, and (4) test the specific contribution of aerobic capacity to DH performance. STUDY 1 identified aerobic capacity, handgrip endurance, anaerobic power, rider skill, and self-confidence as potentially important for DH. In study 2 the rider-skill measure displayed good interrater reliability. Study 3 found that rider skill and handgrip endurance were significantly related to DH ride time (β=-0.76 and -0.14, respectively; R2=.73), with exploratory analyses suggesting that DH ride time may also be influenced by self-confidence and aerobic capacity. Study 4 confirmed aerobic capacity as an important variable influencing DH performance (for a DH ride, mean oxygen uptake was 49±5 mL·kg(-1)·min(-1), and 90% of the ride was completed above the 1st ventilatory threshold). In order of importance, rider skill, handgrip endurance, self-confidence, and aerobic capacity were identified as variables influencing DH performance. Practically, this study provides a novel assessment of rider skill that could be used by coaches to monitor training and identify talent. Novel intervention targets to enhance DH performance were also identified, including self-confidence and aerobic capacity.

Akutverletzungen und Überlastungsschäden der Schulter im Sport

During sports the shoulder complex is exposed to considerable load especially where throwing is important and various pathological changes can occur. In the last two decades the shoulder in athletes has become a special term in clinical sports medicine Selective literature review in PubMed and consideration of personal experience, research results as well as national and international recommendations In general acute lesions of the shoulder caused by sudden sport injuries, such as traumatic luxation, acromioclavicular (AC) joint disruption, traumatic tendon ruptures, labral lesions, cartilage defects and fractures have to be distinguished from chronic or long-standing pathologies due to recurrent microtrauma, such as overuse bursitis and tendinitis, as well as secondary forms of impingement along with rotator cuff tears and labral lesions. Besides common pathological changes that can be observed in almost all overhead-sports, there are also injuries that are more sport-specific due to the particular load profile in each sport. These injuries are especially common in racquet and throwing sports (e.g. golf, tennis, handball and volleyball) as well as in individual and artistic sports (e.g. swimming, gymnastics, dancing and rowing), contact and extreme sports (e.g. judo, mixed martial arts, bodybuilding, weightlifting, motocross and downhill mountain biking). Knowledge about sport-specific load profiles as well as about the variety of treatment options is crucial for successful treatment of these injuries.

GPS-Based Evaluation of Activity Profiles in Elite Downhill Mountain Biking and the Influence of Course Type

This study aimed to profile the activity patterns of elite downhill (DH) mountain bikers during off-road descending, and to determine the influence of course types on activity patterns. Six male elite DH mountain bikers (age 20 ± 2 yrs; stature 178.8 ± 3.1 cm; body mass 75.0 ± 3.0 kg) performed single runs on one man-made (MM) and one natural terrain (NT) DH courses under race conditions. A 5 Hz global positioning systems (GPS) unit, including a 100 Hz triaxial accelerometer, was positioned in a neoprene harness between the C7 and T2 vertebrae on each rider. GPS was used to determine the temporal characteristics of each run for velocity, run time, distance, effort, heart rate (HR), rider load (RLd) which reflects instantaneous rate of change in acceleration, and accumulated rider load (RLdAcc), which reflects change in acceleration over the event duration. Significant differences were found between NT and MM courses for mean velocity (p<.001), peak velocity (p=.014), mean RLd (p=.001) and peak RLd (p=.002). Significant differences were also found both within and between courses for all velocity parameters, when analysed by intensity zone (p<.05). No significant differences were found between courses for HR parameters by zone, though significant differences were revealed between HR zones within courses (p<.05). This study indicates that course terrain has a significant impact on the activity profiles of DH and that GPS can provide a practical means of monitoring these differences in activity.
