Research question: Does a relative amount of caffeine (2 mg/kg) increase the distance 18-24-year-olds are able to row if implemented 1 hour prior to a 5-minute rowing test when compared to no caffeine? The purpose of this study was to analyze the effect of caffeine on 5-minute rowing distance in 18–24-year-olds. According to Grgic et. al (2020), caffeine ingestion of doses of 6 mg/kg and 9 mg/kg significantly improved 2000-meter rowing ergometer by approximately 4 seconds (i.e., caffeine ingestions reduced the time needed to complete the distance). According to Del Coso et. al (2012), during this study the caffeine beverage was ingested 60 minutes prior to exercise and resulted in an increased maximal exercise by 4% when 6 mg/kg of caffeine was ingested compared to 1 mg/kg. Also, this study found that 6 mg/kg of caffeine ingestion improved knee extensor muscle strength and cycling power production because of a higher voluntary contraction (central effects). According to Gutierrez-Hellin et. al (2020), the group that exercised without the caffeine from ingesting the energy drink completed fewer reps compared to those who ingested 3-6 mg/kg of caffeine.
