      Research conducted in rodents and humans present conflicting results on the relationship between caloric intake and the browning of subcutaneous white adipose tissue (scWAT). For example, exercise combined with caloric restriction did not change browning indices measured from human scWAT samples. In another study, caloric restriction in mice resulted in the browning of both scWAT and visceral white adipose tissue. Few investigators, however, have examined the relationship between differences in macronutrient intake and browning processes of human scWAT.
    • Circulating Sclerostin responses to acute weight and non weight bearing sport activity in pre adolescent males

      Mechanical loading, i.e. physical activity and/or exercise, promotes bone formation during growth. Sclerostin, a glycoprotein, mediates osteocytes' response to mechanical loading by inhibiting the Wnt/lf-catenin pathway thereby inhibiting bone formation.
    • The effects of pre-exercise corinthian currants supplementation on antioxidant responses

      Jamurtas, Athanasios Z; Deli, Chariklia K; Fatouros, Ioannis G; Selemekou, Maria; Papoutsis, Alexandros; Koutedakis, Yiannis; Karathanos, Vaios (Ovid Technologies (Wolters Kluwer Health), 2016-05)
      Τhe use of nutritional supplements before and during a sporting event, especially of a prolonged nature, is very common among competitors and routinely advised by exercise professionals. Corinthian currants have a high carbohydrate content making them a potentially ideal carbohydrate source for prolonged exercise. However, their effectiveness as an ergogenic aid has never been studied.
