Objective: We aimed to elucidate changes in blood glucose and lipid metabolic parameters after high-carbohydrate diet ingestion in athletes with insulin resistance.
Methods: Ten throwers belonging to the university track and field club participated in this study. They underwent oral glucose tolerance test and high-carbohydrate test on 2 separate days with a 1-week interval. Serum insulin, lipid indices, and blood glucose levels were determined in both tests.
Result: According to the homeostasis model assessment for insulin resistance (HOMA-IR) score, three participants with HOMA-IR ≥2.5 were assigned to the high-HOMA-IR group and the remaining seven to the low-HOMA-IR group. The high-HOMA-IR group showed higher insulin and triglyceride levels after consuming the high-carbohydrate diet. Significant correlations were found between insulin and triglyceride levels and between HOMA-IR score and triglyceride levels after 180 min of a high-carbohydrate diet ingestion (r=0.80, and r=0.70, respectively).
Conclusion: The results of this study suggest that a high-carbohydrate diet results in high insulin levels in athletes with insulin resistance, which could lead to a state of high triglyceride levels.
