In brief: Two separate studies were done to determine the effects of body checking at the Pee Wee level. Study 1 evaluated eight of the smallest and eight of the largest players from leagues that allowed body checking. The players were measured for height, weight, grip strength, maximal skating speed, impact force during a body check, and speed of skating at impact. Significant morphologic differences (p <.05) between small and large players were reflected in forces of impact. Study 2 investigated the incidence and types of injuries sustained among players competing in leagues with body checking and without. In the checking leagues 55.5% of all injuries were due to body contacts, and serious injuries occurred six times more often than in nonchecking leagues. In addition, body checking accounted for 88% of the 25 fractures recorded during one hockey season.
Accidents are the main threat in today's modern world. All though the technological development in automobiles increases day by day, there are no proper advancements in the perspective of accident avoidance and detection before head. This project completely covers the whole system from accident avoidance, detection and the necessary measures to be taken after the accident. By implementing this useful system in every automobile the mortality rate can be reduced up to 90%.It also aims to make driving possible even for the acoustically challenged. At present, there are systems to detect the accidents occurring due to adverse weather conditions and provide necessary aids to the victims affected by such accidents. This system avoids accidents due to collisions occurring between the vehicles because of the driver's negligence. In case of any accidents, there is smart rescue system in the vehicle which helps in sending the location of accident spot to the nearest hospital. While taking the victim to the hospital the smart life saver equipment will update the current health status of the person and sends the details to the hospital so that necessary arrangements are made for the treatment before the arrival of the victim.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
