Some people have a specific amount of water or sports drinks they want to consume each day. Others drink when their coach tells them to, or just drink when thirsty. A study published in The Journal of Sports Medicine and Physical Fitness examines the habits of 253 athletes from a variety of different sports.Subjects were asked to complete fluid intake questionnaires. The range in age was 8 to 63 years. About 3% of subjects competed in international competition with another 34% participating at the national level. The remaining subjects were regionally active. Of those responding, 150 reported fluid intake below recommended levels while 23 consumed fluids at or above published exercise hydration guidelines.
