Descriptive Kinematic Analysis of the Potentially Tragic Accident at the 2020 Austrian MotoGP Grand Prix Using Low-Cost Instruments: A Brief Report

Background: During the first Austrian MotoGP Grand Prix of 2020, following a serious accident involving the riders J. Zarco and F. Morbidelli, Morbidelli’s riderless bike cartwheeled across turn 3, narrowly missing V. Rossi and M. Viñales by just a few centimeters. As is the case with ordinary traffic accidents, analyzing the dynamics of motorcycle racing accidents can help improve safety; however, to date, the literature lacks studies that analyze the causes and severity of such accidents. Hence, the purpose of this study was to analyze the main causes that led to the accident at the 2020 Austrian MotoGp Grand Prix, to quantify the speeds and distances of the bikes and riders involved, and to hypothesize several alternative scenarios using a low-cost method. Method: Kinovea and Google Earth Pro software were used to identify markers along the racetrack and to measure the distances and calculate the time it took the motorcycles to cover those distances. The analyses were carried out on three 30-fps (frames per second) videos. Results: Zarco’s average speed as he was overtaking Morbidelli on the straightaway before turn 2 was 302 ± 1.8 km/h, higher than that of Rins and Rossi (299.7 ± 1.7 and 296 ± 1.7 km/h, respectively). The speed of Zarco and Rossi’s bikes 44.5 m before the crash was the same (267 ± 7.9 km/h). Immediately after overtaking Morbidelli, Zarco moved 2.92 m towards the center of the racetrack from point A to B, crossing Morbidelli’s trajectory and triggering the accident. Morbidelli’s riderless bike flew across turn 3 at a speed of about 76 km/h, missing V. Rossi by just 20 cm. The consequences could have been catastrophic if Rossi had not braked just 0.42 s before encountering Morbidelli’s bike in turn 3. Conclusion: Through a low-cost quali-quantitative analysis, the present study helps us to gain a deeper understanding of the dynamics of the accident and its main causes. Furthermore, in light of our findings regarding the dynamics and severity of the accident and the particular layout of the Red Bull Ring circuit, racers should be aware that overtaking at the end of turn 2, following the same trajectory as the riders involved in the crash, could be very risky.

Lactacidemia during track day motorcycle racing competitions

Introduction: Motorbike racing is one of the most dangerous sports due to high speeds, and it is highly demanding on racers both mentally and physically. Objective: To verify the lactacidemia in motorbike racers before and after the Track Day race. Method: Nine non-professional male riders (33 + 10.39 years) who practiced Track Day race were studied. Plasma lactate was obtained twice: 30 minutes before and 5 minutes immediately after the Track Day race. Results: There was a significant increase in lactacidemia (87.5%) after the 30-minute race (3.77 + 1.38 vs. 7.07 + 1.85 mmol). Conclusion: Lactacidemia in amateur motorbike racers increased significantly after the Track Day race. These data reinforce the results of other studies, which consider motorcycling as a sport high in terms of anaerobic metabolism. Thus, physical trainers and motorcycle racers should adopt strategies to stimulate this metabolic pathway in specific training.

HARGA DIRI DAN AGRESIVITAS PEMBALAP LIAR

The objectives of this research is to find out self esteem and aggressivity of illegal motorcycle racing that are: profile of illegal motorcycle racers who always make agressivity, factors which cause illegal motorcycle racers do the activities of illegal motorcycle racing, self esteem of illegal racers who always make agressivity, and the impact of self esteem towards illegal motorcycle racers. This research uses a qualitative approach with a case study method of two illegal motorcycle racers who have ten years experience in doing illegal motorcycle racing. This case study was conducted in Bekasi, West Java and Special Jakarta Province starting from 22 October until 22 December 2012. Data was gained through observation and indepth interview. The data was triangulated through crosscheck with all information from other sources before it was analysed qualitatively, i.e. classification of data, coding, examining of the hypothesis, interpretation, and conclusion. The findings of the research are: 1) both illegal racers have two self esteem and aggressivity eventhough they have different indicators, 2) factors causes illegal motorcycle racers who do the illegal motorcycle racing in order to be famous, more respectful and not despiced by other people, have a support from friend, as a kind hobby, and interested in doing challenge referring to the adrenalin, 3) self esteem of illegal motorcycle racers caused their aggresivity due to their self defend, and 4) the impactof self esteem of illegal motorcycle racers is that arise aggressivity, and damaging themselves, society, and other illegal motorcycle racers.
