Training.... Ich hab von diesem Zeug noch eine Menge aus meiner Radfahrzeit über und habe jetzt 0,5 Liter immer so 25-30 Min vor dem Training getrunken und hab das Gefühl es füllt die Muskeln ganz gut und die Kraft ist immer da. Früher hab ich es bei Fahrten ab 4 Std benutzt. Wie findet Ihr die Zusammensetzung in Bezug auf KH ? Die Aminos da sind unwichtig. Hab halt einfach das Gefühl das Zeug macht satt und ich fühle mich prall vor dem Training.
von was für'ner art getränk redest du denn genau?
generell sind kurzkettige KHs (und von denen geh' ich bei sportgetränken mal aus) vor dem training eher kontraproduktiv. wenn überhaupt, dann solltest du das nach dem training trinken.
Genau. Die letzte Mahlzeit 3 Stunden vor dem Training. Damit hab ich die besten Erfahrungen gemacht. Ich gehe davon aus, dass durch Sportgetränke (kurz vor der sportlichen Leistung) ausgelöste Insulinreaktion, die Ausschüttung von Noradrenalin vermindert und daher kontraproduktiv sein könnte.
Das kann man so pauschal nicht sagen! Wenn der Zucker zeitnah vor dem Training aufgenommen wird - z.B. 30min - kann er auch günstige Effekte haben. Bei langen Trainingseinheiten kann man zudem versuchen auch während des Training etwas zuckerhaltiges zu trinken. Ich persönlich bin zwar nicht so ein Zuckerfan, aber ich denke, das kommt immer auf einen Versuch an.Zitat:

Habt ihr euch den Link überhaupt angeschaut ? Das ist eine Glukose,Fruktose,Dextrose Mischung in einem bestimmten Verhältnis. 3 Stunden vor dem Training ? Ja da ich ess ich die vorletzte Mahlzeit. Eher 1 Std davor oder kurz davor ;)
Da ist kein Link.Zitat:

Doch - mußt du in seinem ersten Post oben auf "Aminos" klicken. Ist unterstrichen ...Zitat:

Lg, hav :-)
Den meint er aber nicht...Zitat:
Zitat von hav250
das sind hier einige Worte, die hinterlegt sind.
Whey , Aminos , BCAA usw.
Wenn ich auf "Aminos" klicke, komme ich auf eine Shopseite mit 14 Aminosäurepräparaten. Kohlenhydratgetränke finden sich dort nicht direkt.
Glukose und Dextrose sind das Gleiche.Zitat:

Da kannst du genausogut Zuckerwasser trinken, Haushaltszucker ist nämlich ein Zweifachzucker aus einem Molekül Glukose (Traubenzucker) und einem Molekül Fruktose.
ich hab gute erfahrungen mit 13g bcaas + 20g maltodextrin unmittelbar vor dem training gemacht, ich hab dann mehr "biss"
http://www.powerbar.de/products/125/...ink_Lemon.aspx sorry da isser ;)
ja, das ist eindeutig was für nach dem training. :professor:
Die empfehlen es während des Ausdauersports. Ich schluck die Packung noch runter wie gewohnt vor dem Training und dann ist auch gut ;)
Das ist vor als auch während des Trainings geeignet.Zitat:

ausdauersport ist ja auch was ganz was anderes als kraftsport. :professor:
Ist auch im Kraftsport ein Versuch Wert.

ABSTRACT
Seven experienced resistance athletes were studied to evaluate the influence of glucose polymer ingestion on performance during a resistance training workout. Each subject participated in two randomly assigned trials separated by at least one week. On one occasion the subjects ingested a 10 percent glucose polymer solution (GP) (one gram CHO per kilogram of body weight) immediately before exercise, while on another occasion a similarly colored and flavored placebo (P) was ingested. The subjects then performed leg extensions (Nautilus Inc., Deland, Florida) at 80 percent of their previously determined 10-repetition maximums (10 RM), with three minutes of rest between sets. Subjects performed 10 repetitions on the first set and continued until they failed to perform seven repetitions for a set (fatigue). Additional GP (0.17 gram CHO per kilogram of body weight) or P solutions were given after the fifth, 10th and 15th sets. Venous forearm blood samples were taken before exercise, after the seventh set and at the point of fatigue, and were analyzed for glucose and lactate. Blood glucose was significantly higher (p < 0.05) in the GP treatment after the seventh set and at fatigue (10.00 ± 1.00 mM and 8.44 ± 0.70 mM, respectively) compared to the P treatment (6.90 ± 0.25 mM and 6.13 ± 0.24 mM, respectively). Blood lactate was significantly higher for the GP treatment after the seventh set compared to the P treatment (7.10 ± 0.31 mM for GP and 5.57 0.19 mM for P). Performance measured in number of sets (17.1 ± 2.0 for GP and 14.4 ± 1.7 for P) and repetitions (149 ± 16 for GP and 129 ± 12 for P) was greater for GP than for P, and these differences approached but did not achieve statistical significance (p = 0.067 for sets and p = 0.056 for repetitions). The results suggest that glucose polymer ingestion elevates glucose and lactate in the blood and tends to improve performance during multiple-bout (approximately 15 sets) resistance exercise.

A number of physiological events including the level of contractile activity, nutrient status, and hormonal action influence the magnitude of exercise-induced skeletal muscle growth. However, it is not the independent action of a single mechanism, but the complex interaction between events that enhance the long-term adaptations to resistance training. The purpose of the present investigation was to examine the influence of liquid carbohydrate (CHO) and essential amino acid (EAA) ingestion during resistance exercise and modification of the immediate hormonal response on myofibrillar protein degradation as assessed by 3-methylhistidine (3-MH) excretion. After a 4-hour fast, 32 untrained young men (18-29 years) performed a single bout of resistance exercise (complete body; 3 setsx10 repetitions at 75% of 1-repetition maximum; 1-minute rest between sets), during which they consumed a 6% CHO (n=8) solution, a 6-g EAA (n=8) mixture, a combined CHO+EAA (n=8) supplement, or placebo (PLA; n=8) beverage. Resistance exercise performed in conjunction with CHO and CHO+EAA ingestion resulted in significantly elevated (P<.001) glucose and insulin concentrations above baseline, whereas EAA ingestion only increased the postexercise insulin response (P<.05). Time matched at 60 minutes, the PLA group exhibited a peak cortisol increase of 105% (P<.001) with no significant change in glucose or insulin concentrations. Conversely, the CHO and CHO+EAA groups displayed a decrease in cortisol levels of 11% and 7%, respectively. Coinciding with these hormonal response patterns were significant differences in myofibrillar protein degradation. Ingestion of the EAA and CHO treatments attenuated 3-MH excretion 48 hours after the exercise bout. Moreover, this response was synergistically potentiated when the 2 treatments were combined, with CHO+EAA ingestion resulting in a 27% reduction (P<.01) in 3-MH excretion. In contrast, the PLA group displayed a 56% increase (P<.01) in 3-MH excretion. These data demonstrate that not only does CHO and EAA ingestion during the exercise bout suppress exercise-induced cortisol release; the stimulatory effect of resistance exercise on myofibrillar protein degradation can be attenuated, most dramatically when the treatments are combined (CHO+EAA). Through an "anticatabolic effect," this altered balance may better favor the conservation of myofibrillar protein.

To investigate the influence of carbohydrate (CHO) consumption on the acute hormonal response, and chronic adaptation to weight lifting exercise, two studies were conducted. Following a four-hour fast, seven young men (21.3 +/- 3.5 y) performed (on two occasions) a nine-station weight lifting protocol, completing 3 sets of 10 repetitions at 75% of 1RM (series 1). Randomly assigned, one session included the ingestion of a non-caloric placebo, and the other, a 6% CHO solution. For series 2, two groups of young men (21.3 +/- 1.5 y) participated in 12 weeks of progressive resistance weight training. Training for one group included the ingestion of a non-caloric placebo, and the other, a 6% CHO solution. In series 1, weight lifting exercise with CHO ingestion significantly (p < 0.05) elevated blood glucose and plasma Insulin levels above baseline, as well as that occurring with the placebo. This resulted in a significant blunting of the cortisol response (7% with CHO compared to 99% with placebo). These findings indicate that CHO consumption during weight lifting exercise can modify the acute hormonal response to exercise. With series 2, CHO consumption continued to blunt the cortisol response to exercise during the twelve weeks of training. This is in contrast to significantly elevated cortisol levels observed for the placebo control group. Corresponding with the modified response patterns were differences in muscle growth. Weight training exercise with CHO ingestion resulted in significantly greater gains in both type I (19.1%) and type II (22.5%) muscle fibre area than weight training exercise alone. The difference in the cortisol response accounted for 74% of the variance (r = 0.8579, p = 0.006) of change in type I muscle fibre area, and 52.3% of the variance (r = 0.7231, p = 0.043) of change in type II muscle fibre area. These findings suggest that the modification of the cortisol response associated with CHO ingestion can positively impact the skeletal muscle hypertrophic adaptation to weight training.
