Study on Caffeine, Pre-workout, and Exercise Performance

This study is looking at how Ethiopian Coffee, a pre-workout supplement containing anthocyanins and caffeine, and plain water affect your exercise performance. Researchers want to see if these interventions change your anaerobic power, which is measured by how much effort you can put into a 30-second all-out cycling test. You might be able to join if you are a healthy adult between 18 and 35 years old, exercise at least three times a week, and don't have certain heart or metabolic conditions. The study plans to enroll 12 participants, but its current status is unclear.

Study design
This is an interventional study with 12 planned participants. You will receive Ethiopian Coffee, a pre-workout supplement, and water in a random order.
What's involved
You would attend four visits. The first visit is for assessment, and the next three visits involve drinking a beverage and then performing exercise tests, including a 1-mile treadmill run and a 30-second cycling test.
Compensation
Not stated in the trial record.
Follow-up
Your anaerobic power will be measured at 45 minutes post-dose for each intervention condition.

What this trial measures

  • Change in anaerobic power measured by a 30-second all-out effort on a cycle ergometerAt 45 minutes post-dose for each intervention condition

    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.
