Swimming Pool Life-saving Water Towing Ability Construction Of The Evaluation Index System

Research purpose:Swimming pool water rescue towing ability is the key to improve the success rate of rescuing,the swimming pool life system theory analysis and deduction on the basis of describing the theory of towing capacity development,constructs the evaluation index system of swimming pool water rescue towing ability,the basic theory of Yu Fengfu swimming pool life,has certain theory with practical value to promote the healthy development of the cause of life.The research methods:This paper takes Guangdong province for many years engaged in the teaching and life of college teachers experienced or senior coaches as the research object,to build a swimming pool water rescue towing capability index system for the purpose of.By the methods of literature study,questionnaire,interview and mathematical statistics to conduct an empirical research on the swimming pool water towing capacity.The results of the study:Constituted by technology and physical 2 indicators consisting of swimming technology,technology,physical fitness and swimming towing towing physical 4level two indexes and 200 meters breaststroke,side stroke,100 meters breaststroke,crawl and 25 axillary towing three indicators of the swimming pool lifesaving water towing capability evaluation index system.In addition,through expert interviews and statistical parameters of Kendall coefficient,determine the weights of indicators at all levels of swimming pool water rescue towing capability evaluation index system.The weight of one class index technology and physical fitness were: 0.49,0.51,slightly larger than the physical weight;weight distribution of the two indicators for swimming technology(0.23),technology(0.26),towing swimming fitness(0.24)and(0.27)a physical weight is balanced;three level index in 25,according to the jaw towing(0.05)minimum weight,anti breaststroke,supporting technology(0.08)axillary towing maximum weight,and200 meters breaststroke,side stroke treading water,100 meters breaststroke,30seconds-and 25 / axillary towing treading water weight is 0.07,other indicators of the weight is 0.06.
