Background: There are so many kinds of acquaintances with teenagers and one of the most troubling in recent times is motorcycling students who have various deviant behaviors and engage in various kinds of behavior such as racing, brawls, and drinking alcohol. This is because teenagers who are members of motorcycle gangs do not only commit violations that disrupt public order, such as offenses leading to crimes that can endanger the community, such as robbery, persecution that takes the lives of others. This study aimed to explain the assistance of parents with students who often play motorcycle racing at night. Method: The method of searching for articles in several databases using certain keys in the 2015-2020 period. The results of the search found 8 journal articles that met the inclusion and exclusion criteria. Results: The habit of racing among teenagers is a form of juvenile delinquency. The teenagers involved were jockeys, spectators and mechanics. The reason for wild racing is because it is a hobby, channeling automotive talent and stress relief. The reason for racing is because it is a hobby, channeling automotive talent and stress relief. The resulting impact: disturbing the peace of the residents, damaging public facilities when an accident occurs, and the loss of self-ethics of teenagers on the road. Conclusion: There is a relationship between student social behavior and motor racing.

Equine fiction is an established genre in the English juvenile literary canon. Current works in the field appeal to adolescent readers thanks to their interface between classic motifs of vintage and contemporary forms of equine narratives. Performing a close reading of selected passages in Miranda Kenneally’s Racing Savannah (2013), this paper acknowledges how this novel is a revitalization and a challenge to this pattern. Savannah, who is more gifted than her companions, is subordinate to the decisions of the junior of the household where she works. Jack Goodwin, the protagonist’s romantic lead, educated in a neocolonialist background of male jockeying, becomes Savannah’s marker of difference according to her sex and lower socioeconomic status, which lay at the root of her later racialization despite her being a white character. My analysis attempts to expose how these difficulties encountered by the protagonist to become a professional jockey articulate past and present constraints of the horse-racing ladder.

The welfare debate around horse racing appears to be focussed on musculoskeletal injury and the racing of 2-year-olds. Much of this debate appears contrary to the evolutionary history of the horse as a cursorial animal and the capability of the equine musculoskeletal system to respond to the demands of race training. Epidemiological studies have reported that 2-year-old racehorses have a longer time period from entering training to the first race and a greater number of lost training days than older horses. However, this is, in part, due to the time taken to learn to train and the impact of dorsal metacarpal disease, which is due to loading of naïve as opposed to immature tissue. Across several racing jurisdictions and codes, it has been demonstrated that horses that train and race as 2-year-olds have longer, more successful, careers than those that start racing later in life. This positive trend has also been observed with horses starting in equestrian sport at an early age. The literature on the growth and development of the horse indicates that the musculoskeletal system is primed for activity and loading from an early age. Additional exercise for the young horse has a positive rather the negative effect, with many tissues having a sensitive period for ‘priming’ when the horse is a juvenile. This implies that under many modern management systems, the challenge to horse welfare is not ‘too much exercise too soon’ but ‘too little too late’. The current limitation in our understanding is the lack of knowledge of what is the correct exercise dose to optimise the musculoskeletal system. Modern management systems invariably provide too little exercise, but is the exercise data from feral horses the ‘gold standard’, or more a reflection of what the horse is capable of if resources such as food and water are limited? Further research is required to refine our understanding of the optimal exercise levels required and development of greater precision in identifying the sensitive periods for priming the musculoskeletal system.

Cyclists must withstand significant wind force from passing vehicles. This study analyzed the magnitude of wind force generated by different vehicle types (sports utility vehicle, pickup truck, single unit truck, and semi-trailer truck), vehicle speeds (25, 40, and 60 mph), separation distances (2 ft, 4 ft, and 6 ft), and cyclist riding positions (racing and touring). Three research methods were used: field tests in controlled and natural environments, computational fluid dynamic simulations, and scaled-model wind tunnel experiments. The analysis focused on assessing longitudinal and transverse wind forces that are directed at the cyclist in parallel and perpendicular directions, respectively. All three methods showed the expected trend—that wind force increases with an increase in vehicle muzzle bluntness, vehicle speed, and cyclist proximity. Selected measurements and various models are provided. The wind force to knock a cyclist over (i.e., the flipping moment) was calculated for each test scenario (vehicle type, speed, and separation distance) and compared with the recommended limit (17 N) found in the literature. The semi-trailer truck generated flipping moments that exceeded the limit for all scenarios except 25 mph and 6 ft separation. All the vehicles, at all the speeds tested, exceeded the limit at 2 ft separation. This novel use of simulation and wind tunnel experiments provides groundwork for future research.
