Title: Attenuating the decline in ATP arrests the exercise training-induced increases in muscle GLUT4 protein and citrate synthase activity.

Source:Acta Physiol Scand 1999 Jan;165(1):71-9Summary:Thirty-two rats were assigned to one of four groups: control (CON); exercise training (TR); exercise training + clenbuterol treatment (0. 8 mg/kg/day ) (TR + CL) or exercise training + clenbuterol treatment + 2% beta-guanidinoproprionic acid diet (TR + CL + beta) to examine whether alterations in the ATP levels within the muscle mediates exercise training-induced increases in skeletal muscle GLUT4 protein concentration and citrate synthase activity. Exercise training consisted of running the rats 5 d week(-1) for 8 weeks on a motor-driven treadmill (32 m min(-1), 15% grade). Gastrocnemius GLUT4 protein concentration and citrate synthase activity were significantly elevated in the TR animals, but these adaptations were attenuated in the TR + CL animals. Providing beta-GPA in combination with clenbuterol enabled training to elevate GLUT4 protein concentration and citrate synthase activity, with the increase in GLUT4 being greater than that observed for the TR animals. Skeletal muscle ATP levels were reduced in the TR + CL + beta animals while ATP levels in the TR + CL animals were significantly elevated compared with CON. An acute 40-min bout of electrical stimulation of the sciatic nerve was found to lower skeletal muscle ATP levels by approximately 50% and elevate cAMP levels in all groups. No difference in post-contraction cAMP levels were observed among groups. However, post-contraction ATP levels in the TR + CL animals were significantly greater than the other groups. Collectively, these findings suggest that exercise training-induced increases in skeletal muscle GLUT4 protein concentration and citrate synthase activity are initiated in response to a reduction in the skeletal muscle ATP concentration. Discussion:Adaptation to training involves increased oxidative capacity of muscle cells along with increases in the muscle's ability to take up glucose. Increases in the oxidative capacity of muscle cells are characterized by increases in Krebs cycle enzymes. Enhanced glucose uptake is accomplished through increased glucose transporter protein (GLUT 4) content in the muscle cell. The primary function of the Krebs cycle (also called TCA Cycle or Citric Acid Cycle) is to completely oxidize acetyl groups (derived from the breakdown of glucose, fatty acids, some amino acids, & ketones) in a way that results in ATP formation. Oxidation of acetyl CoA accounts for about two thirds of the ATP formation and oxygen consumption in mammals. Citrate synthase is the enzyme which starts the Krebs cycle by combining Acetyl CoA and oxaloacetate to form citrate. By measuring its activity researchers are able to measure increases in oxidative capacity as a result of exercise training. Glucose uptake in muscle tissue occurs by facilitated diffusion. The term "facilitated" refers to the use of proteins, embedded in the cell membrane, which help the glucose to diffuse across the membrane. These proteins don't remain in the cell membrane all the time, rather, they are translocated to the cell surface when insulin attaches to its receptor or when muscle contractions occur. The glucose transporter proteins most sensitive to insulin and muscle contraction are called GLUT 4 proteins.
