About this trial
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.

Water (Placebo)
Other interventionBottled water acting as the placebo

Group B: Anthocyanin-CaffeineExperimental treatment 1 intervention
Group C: WaterPlacebo comparator 1 intervention
Trial outcomes
Primary outcomes
1
Change in anaerobic power measured by a 30-second all-out effort on a cycle ergometer
The primary outcome measured is the change in anaerobic power measured by a 30-second all-out effort on a cycle ergometer using the Wingate testing. This test will determine whether the interventions confer any performance benefit compared to the placebo.
Time frame
At 45 minutes post-dose for each intervention conditionSecondary outcomes
1
1-mile Treadmill time trial
The 1-mile treadmill time trial will help determine if either of the interventions allows for a faster time, translating to an increase in physical performance.
Time frame
At 45 minutes post-dose for each intervention condition2
Agility Reaction Time
Agility reaction time will be measured with light-up buttons, where participants will need to touch the light to measure time. This test will identify if either intervention can reduce reaction time, which may reflect improvements in neuromotor performance.
