- Effect of 6% maltodextrin intake on capillary lactate concentration in soccer playersPublication . Fonseca, Adinylson; Bernardo, Maria Alexandra; Mesquita, Maria Fernanda de; Brito, José; Silva, Maria LeonorRecent literature suggests that ergogenic substances may play a beneficial role in intermittent exercise. Maltodextrin supplementation has been investigated in soccer players, but few studies have been reported. The aim of this study was to evaluate the effect of 6% maltodextrin supplementation on capillary lactate in soccer players. The study was carried out during soccer training, which was characterised by intense activity (90 min). Participants (n = 24) were randomly allocated in control (water) and intervention (6% maltodextrin solution) groups. Capillary lactate levels were evaluated at pre-exercise (0 min—t0), exercise (45 min—t1), and post-exercise (90 min—t2) moments. At t1, the mean capillary lactate concentration value was significantly higher in players not supplemented with 6% maltodextrin (5.47 mmol/L) than in supplemented players (4.79 mmol/L).
- Effect of cinnamon tea on postprandial glucose concentrationPublication . Bernardo, Maria Alexandra; Silva, Maria Leonor; Santos, Elisabeth; Moncada, Margarida Maria; Brito, José; Proença, Luis; Singh, Jaipaul; Mesquita, Maria Fernanda de"Glycaemic control, in particular at postprandial period, has a key role in prevention of different diseases, including diabetes and cardiovascular events. Previous studies suggest that postprandial high blood glucose levels (BGL) can lead to an oxidative stress status, which is associated with metabolic alterations. Cinnamon powder has demonstrated a beneficial effect on postprandial glucose homeostasis in animals and human models. The purpose of this study is to investigate the effect of cinnamon tea (C. burmannii) on postprandial capillary blood glucose level on nondiabetic adults. Participants were given oral glucose tolerance test either with or without cinnamon tea in a randomized clinical trial. The data revealed that cinnamon tea administration slightly decreased postprandial BGL. Cinnamon tea ingestion also results in a significantly lower postprandial maximum glucose concentration and variation ofmaximum glucose concentration (p < 0.05). Chemical analysis showed that cinnamon tea has a high antioxidant capacity, whichmay be due to its polyphenol content. The present study provides evidence that cinnamon tea, obtained from C. burmannii, could be beneficial for controlling glucose metabolism in nondiabetic adults during postprandial period."
