Background
In Japan, many baseball clubs have been trying to increase players’ food intake so that players could increase muscle mass power to obtain better performance. Ways to do this have included increasing protein intake and eating between meals. It is also common in Japan to provide players with a food program which encourages them to eat as much food as they can for 5-7 day. The aim of this supervised program is to increase their food consumption. However, one possible risk is that players develop a strong loathing for food. Therefore, this study targeted the perceptions of players and guardians about a food program.
