Fig. 3

Heart rate (HR, panel a) and oxygen pulse (panel b) 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 7 subjects (one subject omitted due to technical difficulties with HR measurement). Data points connected by dotted lines denote individual responses. † denotes significantly different from HCLF 50% and different from LCHF at all intensities (p < 0.02)
