| Using methods of documentation, expert interviews, questionnaires, tests, mathematical statistics and logical analyses, the study addresses the theoretical and practical issues of physical training for Chinese triathlon elites via the angle of triathlon elites. It probes into the whole physical training system for triathlon elites in China as well as developing application software of such practice, aiming to promote an even more scientific exercise of physical training for Chinese elites of triathlon. Herein are the main conclusions:1. Scientific theory of physical training is the basis for the implementation of physical training. The paper starts from the theories and practical researches of the physical attributes, internal and external factors affecting physical stamina, features of projects, principles and key influences on physical training to build up the scientific theories and principles, shaping prerequisites for the actual practice of physical training for triathlon.2. Physical performance of an athlete is the premise of exercising physical training. The study examines the physical attributes and overall performance of Chinese triathlon elites before suggesting important groundwork for the specific implementation of physical training.3. Physical training manages target improvement of triathlon athletes through exercises and methods of such training, so as to realize the task thereof. The paper, scrutinizing the construction of the system for exercises and methods of physical training, offers theoretical guidelines on actual practice of physical training.4. The Sqlite database is adopted. Programming of“Computer Software for Physical Training System of Chinese Triathlon Elitesâ€, basing on the operation of Microsoft. Net Framework Version 3.5 SPI, has been developed and experimentally applied in the September-to-November preparation of the YOG (the Youth Olympic Games) and the Asian Games in 2010, offering an operational platform of the actual practice of physical training for triathlon athletes. |
