and the associated extra output of CO2 through the lungs acts as one of the principal buffering mechanisms of the body. However observations upon the relation of the magnitude of changes in lactate and CO2 capacity have been contradictory. Mellanby and Thomas (1920) and Evans (1922), by addition of lactic acid to drawn blood, found that the decline in CO2 content was less than the increase in b...

PURPOSE The aim of this study was to investigate the effect of self-paced active recovery (AR) and passive recovery (PR) on blood lactate removal following a 200 m freestyle swimming trial. PATIENTS AND METHODS Fourteen young swimmers (with a training frequency of 6-8 sessions per week) performed two maximal 200 m freestyle trials followed by 15 minutes of different recovery methods, on separ...

Objective To evaluate whether a secondary increase of serum lactate levels in asphyxiated newborns during hypothermia treatment may reflect suboptimal dynamics. Methods-Retrospective case series and review of the literature. We present the clinical course of four asphyxiated newborns treated with hypothermia who presented with hypotension requiring inotropic support, and who displayed a seconda...

Lactate derived from glucose can serve as an energy source in the brain. However, it is not certain how much lactate, directly taken from the blood circulation, may replace glucose as an energy source. This study aimed to estimate the uptake, release, and utilization of lactate entering the brain from the blood circulation. The change in cerebral venous-arterial glucose and lactate differences ...

Background Blackcurrant intake has been reported to increase peripheral blood flow in humans [1], potentially by anthocyanin-induced vasorelaxation and vasodilation [2]. Increased peripheral blood flow may affect the exercise intensity at lactate indicators (e.g. onset of blood lactate accumulation (OBLA) at 4 mmol L) and maximum oxygen uptake. We examined the effect of 1-week Sujon blackcurran...

Blood lactate level and heart rate are the most frequently measured physiological responses of basketball players during a game. The aim systematic review current literature was to examine concentration game, as well determine according player position, play, geographical location gender Time comparisons in separate studies revealed that significantly lower second half than first. Professional ...

In this study, physiological stress and exercise RPE three protocols were compared among footballers. For this purpose, 20 male elite soccer league third member of the province were selected in 2012 and some their physical characteristics such as height and weight, and aerobic capacity, anaerobic power and resting heart rate before the start of the field operations were measured. The amount of ...
