The investigators are conducting a study to see how a commercial pre-workout supplement, coffee, and water affect how well people perform. The study is conducted across four visits. The first visit is to assess the participants, and the next three visits are for testing. Each participant will drink a randomly assigned beverage 45 minutes before testing. Throughout the study, the participants will complete three testing days-each at least three days apart-so they can try all three drinks. The first test is the Wingate test, where the participants pedal as fast as they can for 30 seconds against a set resistance. The second test is a 1-mile treadmill run/walk on an incline, where the participant tries to complete the distance as fast as possible. The third test measures reaction time using light-up buttons to see how quickly a participant responds by touching them. These tests will help determine if any of the drinks improve performance. The results can help people choose the best drink for their workouts or races.
