LEUCYNA I WITAMINA D3 - BOMBY ANABOLICZNE ?
Trening w domu Z archiwum kulturystyki Targowisko Szybkie pytania bez logowania. Ale ten proces mozemy przyspieszyc - przyspieszyc stosujac odpowiednia suplementacje potreningowa. Oczywiscie to jest najbardziej optymalna ilosc - ale dla wielu extremalna. Duzo zalezy od diety calodziennej - od ilosci spozytych weglowodanow - czy tez od wykonanego treningu - a konczac na 'przyswajalnosci' indywidualnej weglowodanow.
Jedni czuja sie dobrze - inni juz nie za bardzo. Jedno jest pewne - weglowodany trzeba spozywac! Kolejne za to takie ze nic tak nie powoduje wyrzutu insuliny jak weglowodany po czesci wiemy ze nie do konca,a moze nie tylko weglowodany,ale trzymajmy sie tego ze na pewno weglowdany i na pewno o duzym IG. Tak wiec ten wyrzut insuliny - jak w wiekszosci dnia nie do konca jest pozadany - jak wiadomo insulina miedzy innymi hamuje lipolize a nasila lipogeneze - tak w tym okresie jest tym czyms na czym nam zalezy!
Insulina jest najsilniejszym hormonem anabolicznym - ale w okresie potreningowym jest silnym antykatabolikiem. Wiec nie dosc ze dzieki niej jest mozliwe dostarczenie glukozy do miesni - bo ona jest kluczem - to rowniez dzieki niej jej wysokiemy poziomowi tuz po treningu hamuje katabolizm.
BCAA nasilaja synteze nowych bialek a w szczegolnosci obecnosc leucyny. Insulina informuje miesnie o zasobach energi glukozy - tylko dzieki insulinie Z drugiej strony leucyna informuje miesnie o ilosci aminokwasow we krwi. Nalezy jeszcze wspomniec ze tuz po zakonczonym treningu wzrasta poziom kortyzolu kataboliczny hormon - co jest kolejnym negatywem.
Ale rowniez wzrasta spoczynkowa przemiana materii resting metabolic rate - RMR. Bardziej jestesmy wrazliwi i bardziej wykorzystamy weglowodany i nie tylko dzieki temu faktowi. Rozwiazanie wszystkim tych problemow - z jednej strony zatrzymanie katabolizmu,uzupelnienie zasobow glikogenu,zmniejszenie poziomou kortyzolu - z drugiej strony nasilenie anabolizmu,wykorzystanie tymczasowej wiekszej wrazliwosci insulinowej mozna uczynic poprzez spozycie 'napoju' bialkowo-weglowodanowego.
Effects of resistance training on protein utilization in healthy children. Public health initiatives promote increased physical activity in children. More specifically, resistance training has recently received attention as an important component of youth fitness programs. The study examined the effect of this mode of exercise on protein utilization in young boys and girls.
Energy and protein intake remained constant. Resistance training resulted in a downregulation in protein metabolism, which may be energy based. Future studies are needed to clarify energy, as well as protein, needs in young children participating in this form of exercise. Mixed muscle protein fractional synthesis rate FSR and fractional breakdown rate FBR were examined after an isolated bout of either concentric or eccentric resistance exercise.
Subjects were eight untrained volunteers 4 males, 4 females. Subjects were studied in the fasted state on four occasions: Exercise resulted in significant increases above rest in muscle FSR at all times: We conclude that exercise resulted in an increase in muscle net protein balance that persisted for up to 48 h after the exercise bout and was unrelated to the type of muscle contraction performed.
We examined the effect of resistance training on the response of mixed muscle protein fractional synthesis FSR and breakdown rates FBR by use of primed constant infusions of [2H5]phenylalanine and [15N]phenylalanine, respectively, to an isolated bout of pleiometric resistance exercise. The exercise test consisted of 10 sets 8 repetitions per set of single-leg knee flexion i. Subjects exercised one leg while their contralateral leg acted as a nonexercised resting control.
We conclude that pleiometric muscle contractions induce an increase in mixed muscle protein synthetic rate within 4 h of completion of an exercise bout but that resistance training attenuates this increase.
A single bout of pleiometric muscle contractions also increased the FBR of mixed muscle protein in UT but not in T subjects. The aim of this study was to investigate whether prolonged one-leg knee-extensor exercise enhances net protein degradation in muscle with a normal or low glycogen content. Net amino acid production, as a measure of net protein degradation, was estimated from leg exchange and from changes in the concentrations of amino acids that are not metabolized in skeletal muscle.
Experiments were performed at rest and during one-leg knee-extensor exercise in six subjects having one leg with a normal glycogen content and the other with a low glycogen content.
Total amino acid production was also fold higher during exercise compared with that at rest difference not significant. The net production rates of threonine, glycine and tyrosine and of the sum of the non-metabolized amino acids were about 1.
Total amino acid production was 1. These data indicate that prolonged one-leg knee-extensor exercise leads to a substantial increase in net muscle protein degradation, and that a lowering of the starting muscle glycogen content leads to a further increase. The carbon atoms of the branched-chain amino acids BCAA , glutamate, aspartate and asparagine, liberated by protein degradation, and the BCAA and glutamate extracted in increased amounts from the blood during exercise, are used for the synthesis of glutamine and for tricarboxylic-acid cycle anaplerosis.
Previous studies using indirect means to assess the response of protein metabolism to exercise have led to conflicting conclusions. The rate of muscle protein breakdown was assessed by 3-methylhistidine 3-MH excretion, and total urinary nitrogen excretion was also measured. Nonetheless, there was no effect of exercise on total nitrogen excretion. Muscle fractional synthetic rate was not different in the exercise vs. Thus we conclude that although aerobic exercise may stimulate muscle protein breakdown, this does not result in a significant depletion of muscle mass because muscle protein synthesis is stimulated in recovery.
The objective of this study was to examine the muscle metabolic changes occurring during intense and prolonged, heavy-resistance exercise.
Muscle biopsies were obtained from the vastus lateralis of 9 strength trained athletes before and 30 s after an exercise regimen comprising 5 sets each of front squats, back squats, leg presses and knee extensions using barbell or variable resistance machines. Each set was executed until muscle failure, which occurred within muscle contractions. Concentrations of adenosine triphosphate ATP , creatine phosphate CP , creatine, glycogen, glucose, glucosephosphate GP , alpha-glycerophosphate alpha-G-P and lactate were determined on freeze-dried tissue samples using fluorometric assays.
Blood samples were analyzed for lactate and glucose. The exercise produced significant reductions in ATP p less than 0. Muscle lactate concentration at cessation of exercise averaged Glycogen concentration decreased p less than 0.
It is concluded that high intensity, heavy resistance exercise is associated with a high rate of energy utilization through phosphagen breakdown and activation of glycogenolysis. The purpose of this investigation was to determine the influence of post-exercise carbohydrate CHO intake on the rate of muscle glycogen resynthesis after high intensity weight resistance exercise in subjects not currently weight training. Total force application was equated between trials using a strain gauge interfaced to a computer.
The subjects exercised in the fasted state. Total force production, preexercise muscle glycogen content, and degree of depletion As anticipated during the initial 2-h recovery, the CHO trial had a significantly greater rate of muscle glycogen resynthesis as compared with the H2O trial.

Effects of ingesting protein with various forms of carbohydrate following resistance-exercise on substrate availability and markers of anabolism, catabolism, and immunity Ingestion of carbohydrate CHO and protein PRO following intense exercise has been reported to increase insulin levels, optimize glycogen resynthesis, enhance PRO synthesis, and lessen the immuno-suppressive effects of intense exercise.
Methods 40 resistance-trained subjects performed a standardized resistance training workout and then ingested in a double blind and randomized manner 40 g of whey PRO with g of sucrose S , honey powder H , or maltodextrin M.
A non-supplemented control group C was also evaluated. Blood samples were collected prior to and following exercise as well as 30, 60, 90, and min after ingestion of the supplements. Results Glucose concentration 30 min following ingestion showed the H group 7. Although some trends were observed suggesting that H maintained blood glucose levels to a better degree, no significant differences were observed among types of CHO ingested on insulin levels.
These findings suggest that each of these forms of CHO can serve as effective sources of CHO to ingest with PRO in and attempt to promote post-exercise anabolic responses http: Each subject completed three sequential trials separated by 3 wk; a supplement was provided immediately and 1-h postexercise: Subjects were given prepackaged, isoenergetic, isonitrogenous diets, individualized to their habitual diet, for the day before and during the exercise trial.
Similarly, both of these trials resulted in increased glycogen resynthesis Postexercise muscle glycogen synthesis is an important factor in determining the time needed to recover from prolonged exercise. This study investigated whether an increase in carbohydrate intake, ingestion of a mixture of protein hydrolysate and amino acids in combination with carbohydrate, or both results in higher postexercise muscle glycogen synthesis rates than does ingestion of 0.
Eight trained cyclists visited the laboratory 3 times, during which a control beverage and 2 other beverages were tested. After the subjects participated in a strict glycogen-depletion protocol, muscle biopsy samples were collected. The subjects received a beverage every 30 min to ensure ingestion of 0. After 5 h, a second biopsy was taken.
Muscle glycogen synthesis was higher in both trials than in the Carb trial Addition of a mixture of protein hydrolysate and amino acids to a carbohydrate-containing solution at an intake of 0. However, glycogen synthesis can also be accelerated by increasing carbohydrate intake 0. Although the importance of postexercise nutrient ingestion timing has been investigated for glycogen metabolism, little is known about similar effects for protein dynamics.
LATE, resulting in a net gain of leg and whole body protein. Therefore, similar to carbohydrate homeostasis, EARLY postexercise ingestion of a nutrient supplement enhances accretion of whole body and leg protein, suggesting a common mechanism of exercise-induced insulin action.
Resistance exercise is a powerful stimulus to augment muscle protein anabolism, as it can improve the balance between muscle protein synthesis and breakdown. However, the intake of food during post-exercise recovery is necessary for hypertrophy to occur.
Therefore, athletes need to ingest protein following exercise to attain a positive protein balance and maximise their skeletal muscle adaptive response. The interaction between exercise and nutrition is not only important for athletes, but is also of important clinical relevance in the elderly. Exercise interventions combined with specific nutritional modulation provide an effective strategy to counteract or reduce the loss of skeletal muscle mass with aging.
A primed, continuous infusion of L-[ringC6]phenylalanine was applied, with blood samples and muscle biopsies collected to assess fractional synthetic rate FSR in the vastus lateralis muscle as well as whole body protein turnover during 6 h of postexercise recovery. We conclude that coingestion of protein and leucine stimulates muscle protein synthesis and optimizes whole body protein balance compared with the intake of carbohydrate only. Effect of carbohydrate intake on net muscle protein synthesis during recovery from resistance exercise The purpose of this study was to determine the effect of ingestion of g of carbohydrates on net muscle protein balance protein synthesis minus protein breakdown after resistance exercise.
One group CHO received a drink consisting of g of carbohydrates 1 h postexercise. The other group Pla received a noncaloric placebo drink. Leg amino acid metabolism was determined by infusion of 2H5- or 13C6-labeled phenylalanine, sampling from femoral artery and vein, and muscle biopsies from vastus lateralis. Arterial phenylalanine concentration fell slightly after the drink in CHO. Pla during last hour. The improved net balance in CHO was due primarily to a progressive decrease in muscle protein breakdown.
We conclude that ingestion of carbohydrates improved net leg protein balance after resistance exercise. However, the effect was minor and delayed compared with the previously reported effect of ingestion of amino acids.
