Overtraining--what do lactate curves tell us?

Overtraining--what do lactate curves tell us?

In a cyclist, competing at national and international level, submaximal lactate concentrations were initially interpreted as improved endurance capacity. However, 2 weeks later, a test in which maximal lactate was measured showed that maximal lactate was decreased as well. Together with the complaints of deteriorating performance and subjective complaints of irritability and sleep disturbances,...

Lactate: What Does It Really Tell Us?

For much of the 20 century, lactate was largely considered a dead end waste product of glycolysis due to hypoxia ... and a key factor in acidosis induced tissue damage. Since the 1970s a lactate revolution has occurred. At present we are in the midst of a lactate shuttle era; the lactate paradigm has shifted. There is essentially unanimous support for a cell to cell lactate shuttle. The bulk of...

Body Temperatures in Dinosaurs: What Can Growth Curves Tell Us?

To estimate the body temperature (BT) of seven dinosaurs Gillooly, Alleen, and Charnov (2006) used an equation that predicts BT from the body mass and maximum growth rate (MGR) with the latter preserved in ontogenetic growth trajectories (BT-equation). The results of these authors evidence inertial homeothermy in Dinosauria and suggest that, due to overheating, the maximum body size in Dinosaur...

Health communication and adolescents: what do their emails tell us?

BACKGROUND It is widely known that barriers exist in communication between adolescents and health professionals. However, little is known about the actual language used by young people articulating such difficulties and whether email might allow them to overcome these problems. OBJECTIVES The aims of this study were to investigate concerns and difficulties relating to communication among adol...
