    Abstract: The abuse of anabolic androgenic steroids by youth and adolescents, athletes and non-athletes, is related to the occurrence of cardiovascular diseases. Contrastingly, green tea prevents and attenuates the cellular damage, improving the biochemical profile and reducing inflammation. This study aims to evaluate the benefits of consuming green tea to ... Show More

    Abstract: Maple syrup (MAP) is derived from the inspissation of acer saccharum sap, and this main material is composed as a sucrose-like carbohydrate (CHO). This food substance has metabolic effects on mammalian cells and some animal models. We hypothesized MAP ingestion would enable athletes to carry out endurance exercise without inhibiting fat oxidation. ... Show More

    Abstract: Ten-step assessments are generally used as means of assessing motor ability in school-age children. However, no method for assessing physical fitness and motor ability has been established that considers changes with age in young schoolchildren in the growth stage. In particular, no method has been constructed to evaluate physical longitudinal data... Show More

    Abstract: Isomaltulose (ISO) is a carbohydrate (CHO) with metabolic properties that makes it slowly digested and less likely to raise postprandial blood glucose response. We considered that isomaltulose ingestion was difficult to inhibit fat oxidation during incremental exercise. Here we investigated the effect of isomaltulose ingestion on fat oxidation duri...
