TI  - Use of the glycemic index: effects on feeding patterns and exercise performance.
PG  - 1-6
AB  - The focus of this paper is on the glycemic index (GI) that provides effectual 
      information on planning nutritional strategies for carbohydrate (CHO) 
      supplementation in exercise. Related research has suggested that the GI can be 
      used as a reference guide for the selection of an ideal CHO supplement in sports 
      nutrition. Recently, the manipulation of GI of CHO supplementation in optimizing 
      athletic performance has provided an exciting new research area in sports 
      nutrition. There is a growing evidence to support the use of the GI in planning 
      the nutritional strategies for CHO supplementation in sports. The optimum CHO 
      availability for exercise has been demonstrated by manipulating the GI of CHO. 
      Research has shown that a low GI CHO-rich meal is a suitable CHO source before 
      prolonged exercise in order to promote the availability of the sustained CHO. In 
      contrast, a high GI CHO-rich meal appears to be beneficial for glycogen storage 
      after the exercise by promoting greater glucose and insulin responses. The 
      prescribed feeding patterns of CHO intake during recovery and prior to exercise 
      on glycogen re-synthesis and exercise metabolism have been studied in the 
      literature. However, the studies on the subject are still limited, leaving some 
      open questions waiting for further empirical evidences. The most significant 
      question is whether CHO supplementation before and after exercise is beneficial 
      when consumed as large feedings or as a series of snacks. Further research is 
      needed on the effect of feeding patterns on exercise performance.
