Abstract

The aim of the study was to determine whether ingestion of 6.4% carbohydrate solution prior to 30 min rowing had any effect on distance rowed. Twelve male participants (aged 22.21±2.47 years) volunteered to take part. Participants ingested either 500 ml of 6.4% flavourless maltodextrin solution (CHO) or water (PLA) prior to exercise. During 30 min of self-paced rowing heart rate (HR), ratings of perceived exertion (RPE), stroke rate, power output and distance covered were recorded every 6-min throughout. Participants rowed significantly (P<0.05) further during the CHO trial (6,714.2±409.9 m) compared to the PLA trial (6,390.8±448.1 m). Power also increased during the CHO trial compared to the PLA (P<0.05). However, there was no difference in RPE. In conclusion, from the current investigation rowers who wish to improve their time trial performance in longer duration events may benefit from the ingestion of CHO prior to competition.
