From: Effect of low- and high-carbohydrate diets on swimming economy: a crossover study
Rate of oxygen consumption (VO2, panel a), respiratory exchange ratio (RER, panel b), and energetic cost of swimming (CS, panel c) at swimming velocities corresponding to approximately 50, 60, and 70% of maximal aerobic capacity (VO2max) following 3 days of high-carbohydrate, low-fat (HCLF) and low-carbohydrate, high-fat (LCHF) diets. Bar graphs denote mean responses and error bars denote standard deviations for 8 subjects. Data points connected by dotted lines denote individual responses
