Splanchnic and peripheral glucose and lactate metabolism during and after prolonged arm exercise.
Splanchnic and peripheral exchange of glucose and gluconeogenic substrates was examined in 12 healthy subjects during 2 h of arm or leg exercise on a bicycle ergometer and during a 40-min postexercise recovery period. The work intensity corresponded to 30% of the maximal pulmonary oxygen uptake. The regional exchange of substrates was evaluated using catheter technique and indicator dilution me...
متن کاملLactate metabolism during exercise: analysis by an integrative systems model.
To provide a framework for quantitative analysis of metabolic and transport processes associated with ATP production during exercise, we adapted a recently developed model that links cellular metabolism and its control to whole body responses at rest. The enhanced model is based on dynamic mass balances for glycogen, glucose, pyruvate (PY), lactate (LA), O2, and CO2 and is solved numerically to...
متن کاملLiver glycogen metabolism during and after prolonged endurance-type exercise.
Carbohydrate and fat are the main substrates utilized during prolonged endurance-type exercise. The relative contribution of each is determined primarily by the intensity and duration of exercise, along with individual training and nutritional status. During moderate- to high-intensity exercise, carbohydrate represents the main substrate source. Because endogenous carbohydrate stores (primarily...
متن کاملCoronary blood flow and lactate metabolism during isometric handgrip exercise in heart disease.
Twenty-one patients with various heart diseases undergoing the coronary sinus catheterization had myocardial blood flow studies before and during isometric handgrip exercise. At 30% of the maximal voluntary contraction (MVC), handgrip increased both coronary sinus blood flow by 19.8% and myocardial O2 consumption by 21.0% on the average as compared to those at rest. At 20% of MVC, the increase ...
متن کاملLactate Kinetics during Multiple Set Resistance Exercise.
Intensive exercise like strength training increases blood lactate concentration [La]. [La] is commonly used to define the metabolic stress of an exercise and depends on the lactate production, transportation, metabolism, and elimination. This investigation compared multiple set training of different volumes to show the influence of exercise volume on [La]. Ten male subjects performed 3 sets of ...
