Following the progress of the society, more and more people, with the sincerity of devotion, sentiment of benefit others, heart of helping and enthusiasm of serving people, are willing to join voluntary service. The 21st Hearing Impaired Olympic and the 8th World Athletic Games will be held in 2009 in Taiwan, the scope of finance, resource and man power will, following the trend of expansion for international games, be greatly in demand. Every game authority would hope to organize a service team of high quality and efficiency, combining people power and passion, so as to let game activities progress smoothly. To comprehend and grasp the participation motivations of the voluntary service personnel completely, take the related factors into consideration, give them what they would like, let sport volunteers gain their sense of achievement while giving full scope of their talents to serve public, would be a too important issue to ignore. Deeply understand the participation motivation of sport volunteers, apart from helping them to teach the organizational goal during their service period, would also make them contribute their talents entirely, let their humanity shine and realize their self esteem, and create a positive and proactive genuine sense towards sport.
