Rat PPARs: quantitative analysis in adult rat tissues and regulation in fasting and refeeding. by: 9. As you can see muscle glycogen / carb stores were the same in both groups at the beginning. And amazingly the low carb athletes replenished carb stores equally as fast as the high carb group following exercise! This brings into question the need to carb up on the weekends when ketogenic dieting.
If you are refeeding because the rest of the time you are both low kcal and liw carb, then the most effective refeeding (for leptin) will be one low fat, moderate protein, high starchy carb and/or glucose but low fructose. Skeletal muscle metabolic adaptations in response to an acute high fat diet Suzanne Mae Bowser ABSTRACT Macronutrient metabolism plays an essential role in the overall health of an individual. Depending on a number of variables, for example, diet, fitness level, or metabolic disease state, protein, carbohydrate and fat have varying capacities to be.
The ability of skeletal muscle to adapt and respond to various nutrient states is critical to maintaining healthy metabolic function. Habitual high fat intake has been associated with reduced oxidative capacity, insulin resistance, increased gut permeability, inflammation, and other risk factors often preceding metabolic disease : Suzanne Mae Bowser.

Effects of Fasting, Refeeding, and Fasting With T3 Administration on Na-K,ATPase in Rat Skeletal Muscle Masako Matsumura, Nobuaki Kuzuya, Yasushi Kawakami, and Kamejiro Yamashita It is known that Na-K,adenosine triphosphatase (ATPase) in cell membranes represents an important consumer of cellular energy, eg, adenosine triphosphate (ATP), and that the concentration and activity of this Cited by: This study determined whether an acute alcohol dose could inhibit the refeeding response in starved muscle.
Rats starved for 24 h were pretreated with alcohol or saline before refeeding by intragastric or intravenous infusion of enteral diet (ENT), total parenteral nutrition (TPN), or saline.
An early specific effect of carbohydrate refeeding was an increase in the insulin response in glucose metabolic pathways in adipose tissue. Inhibiting carbohydrate absorption by a glucosidase inhibitor and refeeding book caused a delay in energy accumulation during refeeding both in glycogen stores, and, more markedly, in adipose tissue triglyceride by: Skeletal muscle fiber is largely classified into two types: type 1 (slow‐twitch) and type 2 (fast‐twitch) fibers.
Meat quality and composition of fiber types are thought to be closely related. The postoperative reduction in insulin sensitivity is similar to that seen in other conditions associated with insulin resistance such as type 2 diabetes and ageing.1, 6 Studies on patients with The functional response of rat skeletal muscle to fasting conditions suggested a link between the development of insulin resistance and impaired mitochondrial function in skeletal muscle.1, 7, 8 Compared to younger controls, elderly insulin-resistant subjects had a 40% reduction in the basal rates of muscle mitochondrial Cited by: Because skeletal muscle accounts for 65–90% of glucose clearance during a hyperglycemic challenge (10, 15, 18), insulin signaling in skeletal muscle has been a major focus of the adaption to interventions aimed at improving insulin sensitivity.
However, nutritive blood flow to metabolically active tissue is an important component of insulin Cited by: The present study investigated the effects of fasting and refeeding on the expression of proteasome-related genes and their downstream targets in the skeletal muscles of chicks.
Seven-day-old chicks were fasted for 24 or 48 h and then refed for 4 by: 9. The role of USF in the insulin response was suggested by Casado et al., who showed that germ line knockout of either USF-1 or USF-2 largely blocked the induction of FAS transcription in a fasting-refeeding protocol.
Considered together with the data in the SCAP-deficient mice, these data indicate that nuclear SREBPs are both necessary and. repeated fasting-refeeding experiments in humans, animal experiments have been conducted to investigate effects on lipid and carnitine profiles.
In this research, we used five groups of mice: one fed a normal diet while the others were subjected to fasting, and fasting-refeeding repeated once, twice, and three times, respectively.
tion from skeletal muscle.3 Other adaptive mecha-nisms include an overall decrease in liver gluconeo-genesis, a decline in basal metabolic rate, reduction in the secretion of insulin, and an increased use of free fatty acids by the brain as the primary energy source in place of glucose. Refeeding With the reintroduction of carbohydrate via oralFile Size: KB.
Reduced mitochondrial capacity in skeletal muscle has been observed in obesity and type 2 diabetes. In humans, the aetiology of this abnormality is not well understood but the possibility that it is secondary to the stress of nutrient overload has been suggested.
To test this hypothesis, we examined whether sustained overfeeding decreases skeletal muscle mitochondrial content or impairs by: 2.

Fasting preferentially consumed mesenteric fat mass and decreased the cell size of mesenteric depots; however, refeeding recovered the mass and morphology of inguinal adipose tissues preferentially compared with visceral by: Understanding the bone metabolic response to exercise following fasting and feeding is important, since the practice of periodic fasting, be it for training, health or indeed cultural or religious purposes , might influence the risk of skeletal injury and longer-term bone Size: 2MB.
To investigate the effects of dietary crude protein (CP) restriction on muscle fiber characteristics and key regulators related to protein deposition in skeletal muscle, a total of 18 growing-finishing pigs ( ± kg) were allotted to 3 groups and fed with the recommended adequate protein (AP, 16 % CP) diet, moderately restricted protein (MP, 13 % CP) diet and low protein (LP, 10 % CP Cited by: A role for FGF-6 in skeletal muscle regeneration.

Blanksby 7 1 School of Health Sciences, University of Wollongong, NSWAustralia; E-Mail: [email protected] An inducible form of NOS (iNOS) has been found in skeletal muscle, and its induction can lead to increase of oxidative stress response in skeletal muscle tissue.
Muscle proteins can be oxidatively damaged and the activation of an energy-independent proteolytic pathway accelerates muscle protein degradation ().
