Acute Effects of Coffee, Anthocyanin-Caffeine Supplement and Placebo on Exercise Performance Markers

Status: Recruiting

Intervention Type: Other, Dietary supplement
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY

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.

Treatments
Experimental: Ethiopian Coffee
A light roast Ethiopian Coffee is used based on previous research using the same technique for brewing. The coffee is brewed using the Aeropress coffee maker and the Timemore C3Pro hand grinder to grind the coffee. The recipe uses 15 grams of ground coffee set at the same grind setting (16 clicks) and 200 grams of water to have a target cup size of 175 mL plus 50 grams of ice to rapidly cool down the drink for consumption.
Experimental: Anthocyanin-Caffeine
An anthocyanin-caffeine pre-workout supplement containing 120 mg of anthocyanins from New Zealand Blackcurrant berries, along with 120 mg of caffeine. This single-serve packet is stirred into 8 ounces of water and served.
Placebo_comparator: Water
Water used as a constant water intake across all three arms
