Single Kayak Athletes Paddle Power And Boat Speed Records And Application Research

The development situation in canoe、kayak、rowing events is in no balance inJiangxi Province(in this Province, sailing boat and sailboard events are notpopular),the men kayak event is the most unsubstantial among all the other aquaticevents,so it is the considerable questions to improve the performance of men kayakersof Jiangxi Province.Specific work capacities refer to the output mechanical work capacities whichimpel paddler-boat forward progress in paddling. Paddlers convert physiologicalenergies to mechanical power to overcome outside drag to impel paddlers-boatprogress in paddling. The performance ability of athletes engage in pace itemsrests with the ability in overcoming outside resistance and oneself resistance in quiteextent. Different from independent basic sports making in strength、speed、enduranceet al, specific work capacity is a compound sports making consist of these making,representing the wholly characteristic of specific physical performance. It is theembodiment of integrate level of the athlete’s competence connecting specificachievement with physical and mechanical mechanism. The ultimate target ofphysical performance training for kayakers is built on specific work capacity ofathletes.On the basis of material analysis and visiting or investigation, this article chooseto study on relationship between specific work index and specific achievement in menkayak one-1000m with even pace profile, in the hope of applying relative studyresults in training practical fields such as athlete’s techniques and enginerysupervision and assessment、the target confirmation of training、the training monitoron effect, enriching the knowledge about essential characteristic and disciplinarian onkayak items, and providing references and suggestions with our men kayak sports inthe development.This study includes three aspects: the status investigation on kayak sports andstudy for development countermeasures in Jiangxi Province; the study on theoreticalrelationship between specific work index and specific achievement for kayakpaddlers;the study in practical application with the theoretical relationship betweenspecific work index and specific achievement.The main methods applied in this study includes: literature analysis; visiting andinvestigation; mechanism study; individual case study.The conclusions are:(1) The development in average propulsion power within a stoke period is the keyfactor in elevating kayak achievement in1000m. The training to kayaker performanceabilities demands the emphases to be elevating average propulsion power within astroke period.(2) The paddler body mass and wind force have a important influence on thepaddler’s performance.(3) The methods with equal power correction may be applied in achievementcomparison and testing in training state. (4) At different performance level,it may establish the training target in specificwork capacities which may be compared with ergometer power index to reflect therealistic gap in specific performance.(5) Make analysis for adaptation principle between body weight and specific workcapacities: for average propulsion power is fixed, achievement will decrease at least0.18％when body weight increases1％, on the contrary, if body weight is fixed,achievement will increase at least0.29％when average propulsion power increases1％. It demands to add average propulsion power0.7％to insure to counteract thenegative effects caused by body weight increases and will not to cause decrease inachievement.
