Comparison of the Reaction Time Between Motorcycle Road Racer and Motorcyclists

Marcelo. Comparison of the Time Between Motorcycle Road Racer Objective: To compare reaction time of Track Day racers with motorcyclists. Method: 10 volunteers were studied (five motorcycle racer 29.4 + 2.6 years and five motorcyclists 22 + 1.4 years). The reaction time (RT) was evaluated in two tests: T1) Specific test, performed with the volunteer performed on a motorcycle and T2) Non-specific test, performed in a simple task. In both tests, the average reaction time was performed (in milliseconds); Number of Hits and Total Task Execution Time (in seconds). Results: In the specific test of reaction time the Track Day racers group was faster than the motorcyclist’s group (0.592 + 0.014 vs. 0.646 + 0.029 ms, p = 0.0059), as well as racers normally more hits (33.6 + 2.79 vs. 17.8 + 6.83, p = 0.0018) and shorter total time to perform the test (52.64 + 6.65 vs. 59.52 + 4, 55 seconds, p = 0.0102). No non-specific tests or performance between the two groups were detected, except for the total time to perform the test, or which was shorter for the Track Day tests (33.17 + 1.0665 vs. 40.65 + 8, 46 seconds, p = 0.05). Conclusion: Track Day racers showed the best reaction time, the number of hits and the task execution time that the motorcyclists.

to athletes in other sports [5]. In this sense, Ebben, et al. [6] point out that the aerobic resistance of racer drivers is similar to that of boxing, basketball, football, athletics, among others. Reaction Time (RT) is the time interval between the generation of visual, audible or tactile stimuli and motor action. This time revolves around values that correspond to milliseconds and depends on factors such as age, physical conditioning, cognitive level, emotional state and gender [7]. Although Reaction Time is related to genetic conditions, it is a sensory quality that can be trained. High-performance athletes can achieve a decrease of approximately 15% in reaction time due to years of training [8]. For the athlete to react to a stimulus, there is a latency period (just before muscle contraction begins), which is shorter or slower due to the quality of the processing of the reference by the central nervous system [7]. It is observed that the RT of elite athletes, is faster when compared to beginners or untrained [9].
According to Tønnessen, et al. [10], in a study comparing the reaction time of 1,319 world champions in the 100-meter dash category, it was observed that the RT of male athletes (0.166 ± 0.030 seconds) was significantly lower than that of female athletes (0.176 ± 0.034 seconds). There was no relationship between RT and height. The best RT was obtained in the age group between 26 and 29 years old in males (0.150 ± 0.017 seconds) and athletes over 30 years old (0.153 ± 0.020 seconds). According to Sparrow, et al. [11], the type of training, testing and the modality practiced by the athlete can influence RT. Gélat, et al. [12] point out that the emotional and attention state interferes with RT, which can be faster, in motivating conditions and/or when the individual remains more attentive and slower, in situations of demotivation or depression. The neurosensory response is extremely important for Motor Sports racers, such as motorcycle race. Being that during races the racers receives different visual, auditory, tactile stimuli and the respective reception, transfer, processing and transfer of this information, in the shortest possible time, are essential for the performance during the competitions.

Objective
To compare reaction time of Track Day racers with motorcyclists.

Sample Characteristics
The accessibility sample consisted of 10 volunteers, who were divided into two groups with five individuals each: G1) Amateur

Exclusion Criteria
Any type of injury that makes bodily movements impossible.
Consumption of substances with caffeine two hours from the tests.
Do not accept to participate in the research.

Ethical Procedures
The research project was submitted to and approved by the

Data Analysis
For comparison between moments, Student's t-test paired for variables with normal distribution was used, with Bonferroni's post-test adopting a 5% significance level for all analyzes. Using the Graph Pad software. The data were also presented descriptively in graphical and tabular form.   can be seen that in the specific test the Track Day racers performed better than the motorcyclists concerning the following variables:

Results
reaction time, number of hits and total time to perform the task.

However, in test 2 considered as a non-specific evaluation of the TR,
there was no statistical difference in the variables studied, except in the total time to perform the task, which was significantly less in favor of the Track Day racers (Graphs 1-6).

Practical Applications
For a motorcyclist to participate in the Track Day, the racers don't need to have experience in racing tracks and/or to have taken a Riding Course and a motorcycle-specific preparation for competitions is also not necessary. Due to these facilities, many motorcyclists, even without the proper preparation to enter a racetrack, are attracted to participate in these races, in some cases with rented competition motorcycles. Our data showed that, for example, the Reaction Time of racers experienced in this type of event is higher than that of motorcyclists who, although experienced, never participated in Track Day. In this sense, the results of this study indicate that it is not enough for the rider alone have experience of daily use of motorcycles in traffic, as the specificity of the riding position seems to significantly interfere in the Reaction Time test. In this sense, it is suggested that motorcyclists who have never participated in Track Day should take courses and training before starting the practice.
On the other hand, we suggest that the specific test protocol used in the present study to evaluate the Reaction Time can be used for the evaluation and/or training of motorbike racers.

Conclusion
It was observed that the Track Day racers presented the best reaction time, number of hits and time of execution of the task than the racers in the specific test. However, in the non-specific reaction time test, there was no significant difference between the volunteers studied, except in the time of the test, where the Track Day racers were faster. These data contribute to reinforce the importance of specificity in motorsports and to the establishment of benchmarks concerning the reaction time of motorbike racers.
