“Background It has been well established that carbohydrate (CHO) consumption before and during exercise improves exercise performance in events lasting longer than selleck chemical one hour, by maintaining blood glucose, high CHO oxidation rates and possibly sparing endogenous glycogen stores [1, 2]. What is less clear is the relationship between the CHO amount, type and form to maximize endurance performance.

Ingestion of a glucose plus fructose drink had higher exogenous CHO oxidation

rates compared to glucose or fructose only drinks due to increased intestinal absorption rate from both the sodium-dependent glucose (SGLT1), fructose (GLUT5), and glucose and fructose (GLUT2) intestinal transporters [1, 6, 8]. Ingestion of a mixed CHO source allows for greater CHO absorption and utilization, which can be beneficial during prolonged exercise. More recently, researchers have investigated whether other CHO forms (solids and semisolids) have the same benefits as

a liquid. No significant metabolic or exercise performance differences have been found when consuming solid or semisolid CHO sources before-exercise Diflunisal [9–11]. Previously in our lab, the effects of a sport drink, sport gel, sport beans and water were studied in trained cyclists during 80-min of exercise at 75% VO2max, showing no significant metabolic or performance differences between the commercial sport selleck chemicals llc products [12]. A series of studies performed by Pfeiffer and colleagues also confirmed that the exogenous CHO oxidation rates between CHO delivery via fluid, semi-solid or solid were similar during 180-min of cycling at 58% VO2max [5, 13]. As individuals decide to take a more whole food approach, other nutritional factors (e.g. dietary fiber) can affect CHO supplementation choice. The low digestibility of fiber can elicit an osmotic and fermentative effect in the intestinal lumen, which can have unwanted side effects such as flatulence, belching, nausea, abdominal pain and diarrhea [14]. The prevalence of gastrointestinal (GI) discomfort may increase when ingesting low digestible CHO combined with exercise, resulting in a decrease in performance.
