Conversely, the consumption of low GI (LGI) carbohydrates results in lower and more sustained levels of blood glucose and a smaller release of insulin. 11, 12 HGI foods may attenuate the fat oxidation stimulated by exercise because insulin inhibits fat oxidation. 13 Meals with LGI that elicit a lower insulin release have the potential to better ...

HGI postprandial glycemic response (**) at 30 min and insulinemic responses (*) at 30, 60, and 90 min are significantly higher than LGI response on days 1 and 5. The observed glycaemic response is significantly associated with the glycaemic index, study day and time of exercise.

升糖指数（glycemic index，简称GI），又名“血糖生成指数”（生糖指数）。 是指某种食物在含碳水化合物标准定量（一般为50克）的食物量时引起血糖上升所产生的血糖升高值（生糖值）与标准碳水化合物（葡萄糖，或，白面包）的升高血糖值的比值。 这种食物和标准碳水化合物的血糖升高值都以时间曲线下面积（IAUC，Incremental Area Under blood glucose Curve）表示。 这个IAUC的时间一般确定为2h。 GI=某种物质的IAUC/标准物质的IAUC*100. 因此，GI值是相对 …

2016年6月1日 · The primary outcome of this study was to determine how the inclusion of LGI and HGI diets (breakfast, lunch, snack and dinner) impacts on 24 hour blood glucose fluctuations and energy regulation. The GR was calculated by first using the first two hour average of CGM interstitial glucose readings under the fasting state as baseline value.

2024年12月13日 · This study aimed to investigate the impact of pre-exercise LGI and high glycaemic index (HGI) rice-based mixed meals on endurance performance among acclimatised trained athletes in HH condition (32 °C, 65% relative humidity).

2011年1月5日 · LGI meals resulted in lower fat oxidation and higher carbohydrate oxidation than the HGI meal in the postprandial period. Conclusions: The results do not support a differential glycemia according to glycemic index during exercise. The ingestion of LGI foods did not lead to higher fat oxidation relative to the ingestion of HGI foods.

In a meta-analysis published in 2003, LGI diets exerted significant benefits on glycosylated haemoglobin (HbA1c) in type 1 and type 2 diabetics as compared to high GI (HGI) regimens .

Purpose: This study aimed to examine the effect of glycemic index of pre-exercise carbohydrate (CHO) ingestion on exercise metabolism and performance. Methods: Eight endurance trained men ingested a high glycemic index (HGI), low glycemic index (LGI), or a placebo (CON) meal 45 min before exercise and then cycled for 50 min at 67% VO2max.

2011年1月5日 · HGI postprandial glycemic response (**) at 30 min and insulinemic responses (*) at 30, 60, and 90 min are significantly higher than LGI response on days 1 and 5. The observed glycaemic response is significantly associated with the glycaemic index, study day and time of …

In young healthy adults, following an LGI diet resulted in lower average day-long glycaemia compared with a macronutrient-matched HGI diet. Our results support the use of LGI diets to reduce the risk of developing glucose intolerance.
