Evidence. Stephens et al. [320] measured the effects of a high molecular weight (HMW) <a href="http://www.medchemexpress.com/Basmisanil.html">RO5186582 side effects</a> rapidly digested modified starch commercially known as Vitargo, a low molecular weight glucose polymer (LMW) (similar to commercial sports drinks), and sugar-free water (SFW) on blood glucose and insulin for two hours after a glycogen depleting exercise (GDE) (60 min at 75  of VO2 max ). Following the two-hour postprandial period each <a href='https://dx.doi.org/10.1002/brb3.242' title='View abstract' target='resource_window'>brb3.242</a> individual performed a 15 min "allout" bout of cycling. Both the HMW and LMW starch elevated blood glucose and insulin during the two-hour recovery versus the SFW, with the initial response (<60 min) of HMW being significantly greater than the LMW. [321] tested blood glucose and insulin response to amylose and amylopectin versus glucose and maltodextrin. Amylose in the form of a resistance starch (see Section 7) acts similar to a dietary fiber allowing increased fat oxidation by blunting glucose and insulin prior to exercise, whereas amylopectin (as waxy maize starch) responds similar to a normal CHO (i.e., glucose). In their study [321] male cyclists ( = 8) completed a GDE (60 min at 75  of VO2 max ).T recent data suggest that multipletransportable-carbohydrates containing a combination of glucose/maltodextrin + fructose in combination with electrolytes are the most favorable beverages to ingest during endurance exercise to enhance performance. Specifically, a 6?8  carbohydrate mixture of glucose and fructose (GF) plus an electrolyte solution containing NaCl and K will further aid endurance performance [318]. Coconut water is also gaining in popularity due to its high K concentration. Mixing the coconut water with a GF plus NaCL solution may serve as another electrolyte beverage to enhance hydration and performance. 6.5. Modified and Resistant Starches. As previously mentioned (see carbohydrate intake), endurance athletes must maintain blood glucose and replenish glycogen stores during and following longer bouts, respectively [92, 273]. Indeed, the type of CHO (glycemic index and gastric-emptying rate) in relation to the timing of exercise (pre- and during exercise) is critical in the maintenance of blood glucose and <a href='https://dx.doi.org/10.1016/j.addbeh.2012.10.012' title='View abstract' target='resource_window'>j.addbeh.2012.10.012</a> insulin, sparing hepatic glycogen stores, and manipulating substrate utilization for endurance exercise. The blood glucose and insulin responses vary depending on CHO digestion and gastric-emptying rate and need to be considered prior to competition. In efforts to minimize and control the spike in blood glucose and insulin from CHO intake prior to exercise, research has turned to the use of modified and resistance starches as CHO alternatives. Mechanism. Modified starches have gained popularity because of the benefits to digestion and gastric-emptying rate mostly due to the amylose : amylopectin ratio. In general, the higher the ratio of amylose : amylopectin, the greater the resistance to digestion [319], blunting23 the initial response of blood glucose and insulin. This spares glycogen stores and enhances fat oxidation. However, it should be noted that despite the amylose : amylopectin ratio the gastric emptying and absorption rates may also be manipulated by modifying the different starches consumed (i.e., hydrothermal modification) [253]. Evidence. Stephens et al. [320] measured the effects of a high molecular weight (HMW) rapidly digested modified starch commercially known as Vitargo, a low molecular weight glucose polymer (LMW) (similar to commercial sports drinks), and sugar-free water (SFW) on blood glucose and insulin for two hours after a glycogen depleting exercise (GDE) (60 min at 75  of VO2 max ).
