“Background Sweet cassava is a major food or food ingredient in many countries.
The composition of this tuber is 38% carbohydrate and 60% water . A few studies [2–4] have indicated that the carbohydrates in cassava tubers contain monosaccharides (fructose, arabinose, and galactose) and polysaccharides. It has been reported that the intake of high-carbohydrate foods increases muscle glycogen content, which can prolong PSI-7977 exercise time and delay fatigue [5, 6]. Generally speaking, many sports, such as soccer, tennis, and track and field events, require athletes VX-765 research buy to compete repeatedly within the space of a few days. In addition, athletes train almost every day. If an athlete can maintain muscle glycogen via dietary supplementation, he/she can recover efficiently and engage in subsequent training or competition. Consequently, studies have examined the effects of regimens and substance supplementation on muscle glycogen and sports performance, for example, carbohydrate loading [7, 8] and consumption of fenugreek seeds . Recently, several studies have indicated that extracted polysaccharides selleck chemical provide the following benefits: enhancing muscle glycogen
and sports performance, extending endurance times, resistance to fatigue, decreasing oxidative stress after strenuous exercise [10–12], and detoxifying the body . Although sweet cassava is a staple food in many countries, and the literature indicates that it contains abundant carbohydrates and seems beneficial for sports performance, no study has reported the effects of sweet cassava or its extracted polysaccharides on sports performance. Therefore, the aim of this study was to examine the effects of sweet cassava polysaccharides (SCPs) on sports performance using a rat model. In addition to looking at exercise duration times, blood metabolites, such as free fatty acids (FFAs), blood glucose, and insulin, were measured. SSR128129E We
hypothesized that SCP supplementation would increase muscle glycogen and prolong the running time to exhaustion. Materials Male Sprague–Dawley (SD) rats (five weeks old and weighting 180~200 g) were maintained at a temperature of 24 ± 1°C in humidity-controlled conditions (45%~55%) with a 12-h light/dark schedule (lights on at 0600) and were allowed food and water ad libitum. Thirty SD rats were divided into three groups (10 rats/group): control (C), exercise (Ex), and exercise with SCP supplementation (ExSCP). The sample size in this study was decided by our pilot experiment. The dose and period of SCP supplementation were the same as the current study. Only the difference was that there were four rats in each Ex and ExSCP groups.
