Multiple Choice

Which workout recovery drink is better: water, a fortified sports drink, or chocolate milk? In a study, researchers randomly assigned 50 similar athletes to one of three groups. All subjects participated in the same workout. Depending on which group they were assigned to, subjects then drank 12 ounces of water, a fortified sports drink, or chocolate milk. Afterwards, subjects were measured for muscle fatigue. Researchers found that the athletes that drank chocolate milk after a workout recovered from muscle fatigue faster than either those who drank water or the sports drink. For this controlled experiment, identify the treatment and the response variables.
