Location-based Mobile Games in mHealth: A Preliminary Study of Pokémon Go in Promoting Health Exercising

Location-based mobile games such as Pokémon Go might improve players’ physical activities (e.g., walking) and social interactions. With a limited research on mobile exergaming activities, this study examined relationships among Pokémon Go players’ gaming activities, willingness to communicate, and the likelihood of engaging in exercises. Our study showed that the longer participants had been playing the game, the higher the likelihood that they would engage in exercises. Our findings revealed a positive relationship between exercise during gameplay and willingness to communicate with other players. Our study provides implications to the use of location-based mobile games to promote health campaigns and improve the general health of the population

AN ANALYSIS OF PROJECTION ANGLE OF THE LONG JUMP

The purpose of this study was to evaluate the optimum projection angle and to determine the characteristics of optimal takeoff techniques. Subjects of this study included 12 male and 12 female elite long jumpers. Their performance was filmed at long jump event of the 8th China National Games. Mathematical methods, including regression analysis were used to determine the relationship of projection angle with projection velocity and projection distance, then to calculate the optimum projection angle. It was concluded that an increase in projection angle, at the expense of a normal loss of projection velocity, would benefit the projection distance according to the capability of Chinese elite long jumpers. It was also concluded that the takeoff leg should extend forward more before active landing in order to avoid extremely small segment angles of the shank
