“…[11][12][13] Force exposure varies as a function of motorsport type, event class or series, terrain and race conditions (eg, oval track vs road), and/or crash event characteristics, including changes in velocity, peak acceleration, number of impacts, and vehicle dynamics. 14 The combination of these factors results in a unique biomechanical force signature translated to drivers in a crash and is accumulated over time. 10 Very few studies have examined the prevalence rate of concussion in professional motorsport.…”

ImportanceProfessional motorsport drivers are regularly exposed to biomechanical forces comparable with those experienced by contact and collision sport athletes, and little is known about the potential short-term and long-term neurologic sequelae.ObjectiveTo determine whether cumulative impact exposure is associated with oculomotor functioning in motorsport drivers from the INDYCAR professional open-wheel automobile racing series.Design, Setting, and ParticipantsThis is a longitudinal retrospective cohort study conducted across 3 racing seasons (2017-2019). Statistical analyses were conducted in November 2021. Data were retrieved from a secondary care setting associated with the INDYCAR series. INDYCAR series drivers who participated in 3 professional level racing seasons and were involved in at least 1 contact incident (ie, crash) in 2 of the 3 seasons were included in the study.ExposureCumulative acceleration and deceleration forces and total contact incidents (ie, crashes) measured via accident data recorder third generation chassis and ear accelerometers.Main Outcomes and MeasuresPostseries oculomotor performance, including predictive saccades, vergence smooth pursuit, and optokinetic nystagmus, was measured annually with a head-mounted, clinical eye tracking system (Neurolign Dx 100).ResultsThirteen drivers (mean [SD] age, 29.36 [7.82] years; all men) sustained median resultant acceleration forces of 38.15 g (observed range, 12.01-93.05 g; 95% CI, 30.62-65.81 g) across 81 crashes. A 2-way multivariate analysis of variance did not reveal a statistically significant association between ear and chassis average resultant g forces, total number of contact incidents, and racing season assessed (F9,12 = 0.955; P = .54; Wilks Λ = 0.44).Conclusions and RelevanceIn this cohort study of professional drivers from the INDYCAR series, there were no statistically significant associations among cumulative impact exposure, racing season assessed, and oculomotor performance. Longitudinal studies across racing seasons using multidimensional examination modalities (eg, neurocognitive testing, advanced imaging, biomarkers, and physical examination) are critical to understand potential neurological and neurobehavioral sequelae and long-term consequences of cumulative impact exposure.

“…For this reason, driving a performance car in regular belts would cause the body to move cumbersomely on the seat, which would be a hazardous condition for efficient maneuvering of the vehicle. The use of sport harnesses eliminates this inconvenience, making car steering more comfortable and precise [17,25].…”

Safety belts are one of the most significant elements of car equipment classified as passive safety. This paper provides a comparative material analysis of critical components of a trusted manufacturer's six-point harness used in motorsports racing with commercially available imitation belts. Despite the FIA certification labels, the imitation belts are characterized by extremely poor quality in the selection of materials for components such as the snap hooks and the locking sleeves in the central fastening mechanism, posing a real hazard to unaware belt users. At the same time, the results of the research are also intended to build consumer awareness of the risks associated with the purchase of passive safety equipment from unreliable sources or/and at discount prices, which entails real threats to life and health.
