Ecologically Valid Carbohydrate Intake during Soccer-Specific Exercise Does Not Affect Running
Performance in a Fed State
Abstract: This study assessed the effect of carbohydrate intake on self-selected soccer-specific runnin performance. Sixteen male soccer players (age 23 ± 4 years; body mass 76.9 ± 7.2 kg; predicted VO2max = 54.2 ± 2.9 mL·kg−1 ·min−1; soccer experience 13 ± 4 years) completed a progressive multistage fitness test, ...
Critical evaluation of food intake and energy balance in young modern pentathlon athletes: a cross-sectional study
Abstract
Background: Modern pentathlon comprises five sports: fencing, swimming, equestrian jumping, and a combined
event of pistol shooting and running. Despite the expected high energy demand of this sport, there are few
studies that provide support for the nutritional recommendations for pentathletes. The purpose of the ...
Carbohydrate Nutrition and Team Sport Performance
Abstract The common pattern of play in ‘team sports’ is ‘stop and go’, i.e. where players perform repeated bouts of brief high-intensity exercise punctuated by lower intensity activity. Sprints are generally 2–4 s long and recovery between sprints is of variable length. Energy production during brief sprints is derived from the degradation of intra-muscular phosphocreatine and ...

Zinc is a critical regulator of placental morphogenesis and
maternal hemodynamics during pregnancy in mice
Zinc is an essential micronutrient in pregnancy and zinc defciency impairs fetal growth. We used a mouse model of moderate zinc defciency to investigate the physiological mechanisms by which zinc is important to placental morphogenesis and the maternal blood pressure changes during pregnancy. A 26% reduction in circulating zinc (P=0.0...
Environmental exposure to zinc and copper influences sperm quality in fertile males
Introduction. The presented study was designed to investigate the associations between environmental exposure to zinc and copper and levels of the parameters of oxidative stress and antioxidant defence system and selected cytokines in the
seminal plasma of fertile males.
Materials and methods. The study population consisted of 65 fertile male volunteers from ...
Zinc as a Gatekeeper of Immune Function
After the discovery of zinc deficiency in the 1960s, it soon became clear that zinc is
essential for the function of the immune system. Zinc ions are involved in regulating intracellular signaling pathways in innate and adaptive immune cells. Zinc homeostasis is largely controlled via the expression and action of zinc “importers” (ZIP 1–14), zinc “exporters” (ZnT 1–10), and zinc-binding ...
