The current study explores international tourists’ experiences of watching professional baseball games in Korea. Total 152 reviews posted by tourists on TripAdvisor were analyzed through Leximancer, a computer program used in the qualitative content analysis. The software identified three dominant themes of tourist experiences: the distinctive atmosphere of Korean professional baseball games, the diverse services in the stadium, and fanatical cheering behavior for the team. Moreover, it revealed that international tourists were generally positive toward the culturally distinctive style of Korean professional baseball games. This study suggests that the professional sports of a travel destination can be a form of providing international tourists with pleasurable experiences and a way to learn about the distinctive Korean baseball culture. 相似文献

The speed at which a player can swing a bat is central to the games of baseball and softball, determining, to a large extent,
the hit speed of the ball. Experimental and analytical studies of bat swing speed were conducted with particular emphasis
on the influence of bat moment of inertia on swing speed. Two distinct sets of experiments measured the swing speed of colege
baseball and fast-pitch softball players using weighted rods and modified bats. The swing targets included flexible targets,
balls on a tee and machine pitched balls. Internal mass alterations provided a range of inertial properties. The average measured
speeds, from 22 to 31 m s−1, are consistent with previous studies. Bat speed approximately correlates with the moment of inertia of the bat about a vertical
axis of rotation through the batter's body, the speed generally decreasing as this moment of inertia increases. The analytical
model assumes pure rotation of the batter/bat system about a vertical axis through the batter's body. Aerodynamic drag of
the batter's arms and the bat is included in the model. The independent variable is bat moment of inertia about the rotation
axis. There is reasonable agreement between the model and the measured speeds. Detailed differences between the two suggest
the importance of additional degrees of freedom in determining swing speed. 相似文献

Abstract Measurements are presented of the speed at which six different rods could be swung by four male students. Three of the rods had the same mass but their swing-weight (i.e. moment of inertia) differed by large factors. The other three rods had the same swing-weight but different masses. Our primary objective was to quantify the effects of mass and swing-weight on swing speed. The result has a direct bearing on whether baseball, tennis, cricket and golf participants should choose a heavy or light implement to impart maximum speed to a ball. When swinging with maximum effort, swing speed (V) was found to decrease as swing-weight (I o) increased, according to the relation V?=?C/I o n , where C is a different constant for each participant and n?=?0.27 when I o >?0.03 kg?·?m2. Remarkably similar results were obtained previously with softball bats (where n?=?0.25) and golf clubs (where n?=?0.26). Swing speed remained approximately constant as swing mass increased (when keeping swing-weight fixed). The implications for racket power are discussed. 相似文献
