| Abstract: | Purpose: To illustrate the effects of low-carbohydrate (LC) and grain-based (GB)
diets on body composition, biomarkers, athletic training, and performance in an
elite triathlete. Methods: The athlete followed 2 dietary interventions for 14 d
while maintaining a prescheduled training program. Pre- and postintervention
measurements for each diet included plasma and serum samples, resting energy
expenditure, body composition, and a performance bike ride. Results: Compared
with the GB diet, the LC diet elicited more disruptions to training and unfavorable
subjective experiences. Total cholesterol, HDL cholesterol, LDL cholesterol,
ratings of perceived exertion, and heart rate were elevated in the LC diet. Blood
insulin, resting lactate, postexercise lactate, and C-reactive protein were lowest
in the LC diet. Conclusion: The LC diet resulted in both favorable and unfavorable
outcomes. The primary observation was a disruption to scheduled training
on the LC diet. Researchers should consider how the potential mediating effect disruptions to training could influence pretest-posttest designs. |
