A ketogenic diet induces a state of nutritional ketosis defined by an elevated ketone concentration within the blood range >0.5 to 5 mmol/L that over time results in a keto-adapted phenotype. Ketones contribute to many of the therapeutic and performance benefits associated with nutritional ketosis, and as a result, exogenous ketone supplements have become commercially available that are capable of inducing acute nutritional ketosis without restricting carbohydrate. The primary purpose of this study was to test the efficacy of a ketone-salt/caffeine supplement versus water on physical and cognitive performance in non-keto-adapted individuals. Twelve recreationally trained individuals (4 women; 8 men; mean age 22.9 ± 1.9 yr, body mass 79.3 ± 16.7 kg) participated in two experimental sessions in a randomized and balanced order. Subjects consumed either a ketone-salt/caffeine supplement or water (control condition) 15 min prior to performing a staged cycle ergometer time to exhaustion test followed immediately by a 30 sec Wingate test. Symbol digit modality tests were administered at baseline, immediately post-exercise and 30-/60-min post-exercise. Blood ketone concentrations were significantly increased peaking 15 min after ingestion by more than 2-fold and staying elevated throughout 60 min recovery. Compared to the water trial, ingestion of the ketone/caffeine supplement significantly increased time to exhaustion (8.3%) and average power during the Wingate (4.3%). There were no significant differences between conditions in peak power output, cognitive performances, or blood glucose responses. These results indicate that ingestion of exogenous ketone-salts combined with caffeine is well tolerated and induces acute nutritional ketosis and is associated with improved high intensity exercise capacity in non-keto-adapted individuals. 2017-09-01 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1492436132235977 http://rave.ohiolink.edu/etdc/view?acc_num=osu1492436132235977 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
