Intensive understanding of sports biomechanical principles is an essential issue for sprint kayaking. In recent years, the authors have studied the acquisition of biomechanical information and the evaluation of competitive ability on sprint kayaking. In this study, first, an oar force sensor was developed to detect the stroke forces applied by paddler. The sensor was attached to a paddle with minimum mechanical involvement, hence the mechanical properties of the paddle was not changed. Second, an on-water instrument of biomechanical information acquisition was developed to detect stroke force, stroke frequency, stroke power, kayak speed, and acceleration synchronously. Third, 12 evaluation factors for kayaking ability were proposed based on the factor analysis. The 12 factors include (1) the stroke rate; (2) the speed fluctuation; (3 and 4) the hull pose (L/R); (5 and 6) the stroke force (L/R); (7 and 8) the endurance (L/R); (9 and 10) the stroke technique (L/R); (11 and 12) and the stroke rhythm (L/R). Finally, the stroke rate and the forward stoke technique was analyzed briefly.
Culture and Tourism Integration" and "Internet plus Tourism" are hot topics under the guidance of national policies in recent years, but previous studies in this field have relatively neglected this aspect of service innovation. And service innovation is of great significance to promote industrial integration and better realize the tourism supply-side reform. To this end, the article combines the four-dimensional mode of service innovation, studies typical service innovation events of Ctrip Tourism Group, sums up its successful experience in the process of service innovation, and expounds the inspiration of current tourism companies in service innovation. The research has certain enlightenment to promote the development of the new format of the integration of culture, tourism, and the Internet, to form a tourism enterprise brand, and to meet the service needs of tourists.
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.
