[Dannytech]

grazie mille ancora per il benvenuto ragazzi!!!

Matteo, so cosa stai provando per la perdita... io ho avuto cani sin da quando sono nato praticamente e ci sono passato varie volte. Ognuno di loro è unico e ti lascia dentro certi ricordi che a volte nemmeno le persone riescono a lasciarti, anche perchè quello che ti danno te lo danno davvero con il cuore e senza secondi fini o convenienze...

Per quanto riguarda l'infortunio stringi i denti e vedi di recuperare al 101%, 15 giorni passano in fretta.... e poi, un guerriero qualche ferita addosso ogni tanto ce l'ha

[The Undertaker]

Infatti Danny quello è il mio spirito...

Giovedì sono andato via dalla palestra claudicante...prima dal dolore ero svenuto e avevo avuto addirittura il vomito...
Ho avuto davvero tanta paura...più che altro per aver rovinato la preparazione...solo Fabio sa quello che sto dando...e buttare via tutto per aver dato sempre il 101% è davvero triste.
Il mio spotter si è impaurito credendo che il rumore (causato dallo strappo) non venisse dal mio muscolo...quando ha capito che la cosa era seria...si è impressionato pure lui.

Comunque sono salito il giorno dopo in cyclette...per muovere la zampa...e subito mi sono dato da fare per rimediare...
Non sarà questo a buttarmi giù...ci vuole ben altro...

Best Contractions for Muscle Growth

Many people have written to me over the last few months, asking for more information about incorporating eccentric training into their workout routine to stimulate muscle hypertrophy. Eccentric training, or ‘lowering’ the weight to stimulate muscle growth, is typically utilized with heavy weights and prolonged rest periods (2 minutes or greater). With prolonged rest periods, there is reduced metabolic stress (lactate responses) and lowered GH and testosterone responses.
It has been known that local accumulation of metabolic subproducts such as lactate and hydrogen ions stimulates sympathetic nerve activity and exercise-induced catecholamine (adrenaline) secretion.¹ The increase in metabolic stress with increased lactate and adrenaline has recently been shown to play an important role in the regulation of anabolic hormone secretions from the hypothalamus-pituitary.^2,3
Therefore, increasing the metabolic stress (lactate) may be an additional stimulatory mechanism for muscle growth. For example, Gordon et al.⁴ demonstrated the effect of alkalosis treatment (reduces lactate responses) by sodium bicarbonate (NaHCO₃) ingestion on exercise-induced hormonal response. The NaHCO₃ treatment resulted in a greater pH (reduced lactate), and blunted GH response to 90 seconds of cycle ergometer sprinting, compared to the placebo treatment. Hence, an exercise regimen with greater metabolic stress should cause greater anabolic hormone and catecholamine responses to resistance exercise.
Getting Bigger and Stronger With Increased Metabolic Demand
Exercise with vascular occlusion markedly enhances metabolite accumulation within the muscles and concomitant GH secretion.^2,3 Although it has not been established whether acute increases in GH lead to local skeletal muscle hypertrophy during prolonged strength training, it has been suggested that a transient increase of GH can produce an interaction with muscle cell receptors, aiding recovery and stimulation of hypertrophy.⁵
Another interesting fact is that there are many different peptides of the GH peptide, and responses should be taken into account because GH should not be regarded as a single hormone— but rather as a ‘family’ of related polypeptides that are all derived from one gene.⁶ This molecular heterogeneity may have physiological significance because the different peptides of GH have been shown to possess different biological activities and different effects on lipid, carbohydrate, and protein metabolism.^{6, 7, 8}
In addition, it has been suggested that metabolic stress has a substantial role in stimulating muscular hypertrophy and strength gains. That’s right, not only can increasing metabolic demand cause increases in size— but also strength. For example, Schott et al.⁹ reported that an isometric training regimen resulted in a greater decrease in intramuscular pH (increased lactate production), and induced a greater muscle hypertrophy, compared to a regimen with only a small change in pH.
A previous research study revealed that improvement in strength following six weeks of dynamic resistance training was significantly greater in the regimen without rest, compared to a regimen with a 30-second rest period between each repetition— although the magnitude of muscular hypertrophy was not evaluated.¹⁰ The enhanced metabolic accumulation within muscles caused by vascular occlusion resulted in marked increases in muscular strength¹¹ and muscle cross-sectional area¹² following resistance training.
These findings suggest that exercise-induced metabolic changes may be associated with muscular adaptations to resistance training. Moreover, these effects might be induced, in part, by secretion of anabolic hormones, but no previous studies have been conducted on the influences of exercise-induced metabolic changes on acute hormonal responses and long-term adaptations of muscles.
Increasing Metabolic Demand with Eccentric Exercise
As mentioned previously, incorporating eccentric contractions is a great way to increase muscle mass because you can handle a heavier weight while lowering the weight as opposed to lifting the weight. The only problem with using eccentric exercise with maximum weights is that it only produces small increases in metabolic demand.
For example, studies using ‘eccentric only’ exercise produce very small increases in lactate responses. Researchers from Finland decided to investigate which eccentric load induced the greatest metabolic effect. As discussed earlier, increasing the metabolic demand can increase muscle hypertrophy and strength— so incorporating eccentric exercise with increased training load (weight) and increasing metabolic demand (increased lactate) can produce a dual hypertrophy response.
Researchers had subjects first perform the maximum strength measurements consisting of four conditions with different eccentric (ECC) loads. The four different load levels used for the ECC phase were 60, 70, 80, and 90 percent of concentric 1 RM, whereas the concentric (CON) resistance was sustained at 70 percent of concentric 1 RM. The researchers used a device that allows a person to overload the eccentric portion, while a spring-loaded device unhoists the weight so you can use a lighter concentric weight.
The weight releasers have the potential to maximize the resistance in the ECC phase and to reduce it during the CON phase of the movement. The weight releaser is detached from the strength-training bar at the end of the ECC phase of the movement, whereas the CON phase can be performed with a lower resistance.
The weight releasers detach from the bar and remain at the floor after the exercise is performed. Therefore, an assistant returns the weight releasers on the bar after each repetition, for consecutive repetitions. A hook is placed on the end of the barbell and then you lower a heavier weight. When the bottom hits the ground, the hooks are released and a lighter concentric weight can be lifted.

The study showed that the largest increase was observed in blood lactic acid concentrations from pre- to post-loading during 90 percent eccentric loading/70 percent concentric loading.¹³ The loading-induced increase in GH concentrations during the 90/70 percent loading tended be larger, compared to the other conditions. The study suggests that 90 percent eccentric loading/70 percent concentric loadingleads to the greatest metabolic response, because the increase in blood lactate in the 90/70 percent condition was higher than the 70/70 percent condition. When the loads are expressed differently, the optimal ECC load in the study was 1.2 times the concentric resistance.
Thus, tension overload combined with enhanced metabolic stress may enhance muscle growth compared to performing eccentric exercise alone or ‘pure negatives.’ The combination of enhanced metabolic stress (i.e., enhanced lactate) and tension overload can enhance the muscle hypertrophy response.
If you are going to try this type of workout to enhance muscle mass, you are going to need spotters to help assist with unloading the weight. Another alternative is to use machines. For example, let’s say your maximum bench press is 200 pounds. You would load the machine with 170 and lift the weight, and then have your workout partner push against the bar.

Articolo veramente carino, da un po' che lo lessi appena uscito tra le pagine di MD......nulla di nuovo in particolare ma alcune conferme di quanto stiam dicendo anche quì....

gran bell'articolo doc

anch'io nel mio piccolo sono sempre stato favorevole a questo tipo di allenamento e lo inserisco spesso in varie forme, che siano "hellraiser" (8 rip di cui 5 normali e 3 con negativa enfatizzata) - che poi da quei video che ho visto è una tecnica che anche tu sfrutti molto - o una variante che sto seguendo da 2 weeks, cioè 6rip + 3forzate +2 negative per i muscoli "piccoli", e 8rip + 3 forzate + 2 negative per i muscoli grandi.

Interessantissime le spiegazioni a livello chimico di ciò che accade

ti ringrazio Marco

al momento ho un pò di bf di troppo su abs/fianchi... magari bastasse togliere l'acqua

[MeshuggaH]

Il tipo di stimolo allenante proposto nell'articolo postato dal Doc viene spesso usato anche nei miei allenamenti.
In questo periodo non faccio negative in maniera sistematica, ma mi vengono "ordinate" in determinate serie, per aumentare e variare l'intensità dell'allenamento.

[The Undertaker]

Doc interessante l'articolo...una domanda...
a quanto ho capito andrebbe utilizzanto un peso superiore nella fase eccentrica (si parla di un 90/70)...
Per fare una cosa del genere oltre ad avere 2 spotter...(immagino distenzioni ad esempio...uno carica e l'altro segue)...mi sembra davvero notevole l'incremento di peso...
Si parla di rest anche lunghi... ma un 90/70 è sempre tanta robina...specialmente se come noi non si eseguono poche reps...
Poi l'infortunio con questa metodologia potrebbe essere davvero dietro l'angolo...
Io eseguo spessissimo negative e variazioni di TUT...ad ogni set che faccio...ma un conto è applicarlo con il peso che utilizzi in concentrica...un altro è con un carico decisamente superiore...

tu che ne pensi a riguardo? fatto mai applicare?
