Muscle Hypertrophy 2011 - 0 views

  • mechanical tension, muscle damage and metabolic stress are the three primary factors that promote hypertrophy from exercise
  • The mechanical tension is directly related to intensity of the exercise, which is the key to stimulating muscle growth
  • Muscle damage, that leads to muscle soreness, from exercise training initiates an inflammatory response, which activates satellite cells growth processes
  • ...6 more annotations...
  • metabolic stress that is a result of the byproducts of anaerobic metabolism (i.e., hydrogen ions, lactate, inorganic phosphates) is now also believed to promote hormonal factors leading to muscle hypertrophy
  • The upper extremities tend to show more growth earlier then the lower body
  • Maximal growth occurs with loads between 80-95% of 1 repetition maximum
  • weightlifters and powerlifters show more favorable hypertrophy of type II (fast twitch) muscle fibers
  • body builders appear to have comparable hypertrophy in both the type I (slow twitch) and type II muscle fibers
  • Multi-joint exercises have been shown to produce larger increases of anabolic hormones than single-joint exercises
  •  
    Review of the physiology of muscle building.  The authors review the evidence behind the types of muscle building exercises and the physiology responsible for muscle hypertrophy.  The authors point to Schoenfeld's description of mechanical tension, muscle damage, and metabolic stress to build muscle.

Frontiers | Branched-Chain Amino Acid Ingestion Stimulates Muscle Myofibrillar Protein ... - 1 views

  • BCAAs exhibit the capacity to stimulate myofibrillar-MPS, however a full complement of EAA could be necessary to stimulate a maximal response of myofibrillar-MPS following resistance exercise
  • This information potentially has important nutritional implications for selecting amino acid supplements to facilitate skeletal muscle hypertrophy in response to resistance exercise training and the maintenance of muscle mass during aging, unloading, or disease
  • results from the present study suggest that ingesting BCAAs alone, without the other EAA, provides limited substrate for protein synthesis in exercised muscles
  • ...3 more annotations...
  • the overall response of MPS is not maximized. Instead, the limited availability of EAA likely explains the qualitative difference in magnitude of the MPS response to ingestion of BCAAs alone and ingestion of similar amounts of BCAAs as part of intact whey protein
  • decreased EAA concentrations following leucine ingestion
  • these data support the notion that EAA availability is the rate-limiting factor for stimulating a maximal MPS response to resistance exercise with BCAA ingestion
  •  
    Complete amino acid supplementation exceeds muscle building capacity (myofibrillar-MPS) over BCAA alone.

    muscle loss, sarcopenia is a significant marker of poor health in men.  This study of 845 men age 45-85 finds that low Testosterone, low vitamin D, low physical activity, smoking, and thin body build are associated with sarcopenia in men.

    The early post menopause phase is critical for women. This is the phase that requires intensify strategy for exercise. The ER alpha signaling is actually increased and the ability to build muscle is intensified if exercise, particularly resistance training, is employed.

LH secretion and testosterone concentrations are blunted after resistance exercise in men - 0 views

  •  
    testosterone secretion is blunted for about 12-24 hours after exercise.  The quicker the testosterone rebounds, the faster the muscles rebound and build.

Tricycle For Disabled Children - 0 views

  •  
    The tricycles are individually designed to meet the needs of each disabled child and help provide physiotherapy, build muscle tone and promote play. Italso help benefit growth and development in children with disabilities, enabling them to keep active and retain their independence. Disabled children get huge physical and emotional benefits from having the specially tricycles, which are each custom made to suit the individual child's needs. Riding a tricycle provides both fun and fitness, and is a therapeutic activity that allows children to exercise their lower extremities. As the muscles move through cycling motions, they are flexed, extended and stretched. This range of motion is crucial for children with disabilities, because muscles are incapable of keeping up with bone growth unless fully extended. Tricycles are provided to severely disabled children and adults and come in two sizes, 20 inch and 24 inch models. These trikes are grant funded and to qualify for one of these, an individual must suffer from a condition such as, but not limited to, Cerebral Palsy, Down Syndrome, Traumatic Brain Injury or Autism. Trunk support system is ideal for riders who have trouble remaining upright while seated. An optional headrest is available. A headrest can be purchased with either a flat or contoured headpiece, and adjusts both horizontally and vertically for optimum positioning. The Front Pulley System maintains a level pedal position for children whose extreme tone forces the front of the pedal downward. Turn the oval knob to raise and lower the handlebar. A handbrake for the conventional handlebar will arrive installed on Large tricycle. Open access combined with a low transfer step makes it easy to get on and off trikes. Tricycle Deluxe Double Hand Drive: Frame : Made by E.R.W. Tubes 38.0 mm-16 G. 25.4 mm & 22.22 mm- 18 G. Seat & Back : M S, C.R.C. Sheet. Seat Size 18"x 16" Wheel Size : Wheel Diameter 24"x 1 1/2" Tyre and Tube Standard Company. Pa

Testosterone replacement: Medical alternative to bariatric surgery? : Clinica... - 0 views

  •  
    Testosterone therapy aids weight loss in study of obese men.  The presentation of the potentially biased study (study was funded by the makers of the Testosterone used in the study) proposes Testosterone as a pharmacologic bariatric treatment.  That conclusion is ludicrous!  Testosterone therapy has been shown to improve insulin sensitivity, improve glucose uptake, reduces inflammation, improve muscle building, and reduce the parameters of metabolic syndrome--all of which underlies the obesity.  Thus, men with low T and obesity, Testosterone therapy is playing a causal role in the obesity and thus Testosterone therapy is treating the cause.  But to describe it as pharmacologic bariatric therapy is false and misleading. http://ow.ly/CKrje

  •  
    The ignorance of this authors statements is unmeasurable.  Numerous other studies have shown weight loss in men with obesity is associated with increased Testosterone production.  My book highlights the mechanism by which adipose tissue decreased Testosterone production.  The author was quoted as pointed to no Testosterone replacement (even if levels are low????) despite the evidence that Testosterone will improve glucose metabolism, build muscle (reverse sarcopenia obesity), improve cholesterol metabolism,  and significantly aid Diabetes control just to name a few; yet the author says, give surgery instead.  I am sure the author is a surgeon and thus bias might, just might, be present.

Effects of short-term high-fat overfeeding on genome-wide DNA methylation in the skelet... - 0 views

  • short-term HFO introduces DNA methylation changes on a genome-wide scale in human skeletal muscle
  • These changes were only partly reversed after 6–8 weeks
  • The induction of DNA methylation changes after 5 days of HFO supports the growing awareness of DNA methylation as a dynamic signal that is possibly relevant to short-term day-to-day metabolic adaptations, including acute exercise
  • ...4 more annotations...
  • Diverging DNA methylation levels between elderly, but not young, genetically identical twins indicate that environmental exposures throughout life may permanently influence DNA methylation, suggesting some preservation of de novo DNA methylation in adults
  • our finding of a slow reversibility rate indicates the demethylation process may be somewhat impeded compared with the induction of methylation changes by diet, which could have implications for the preservation or build-up of CpG methylation over time
  • A slow reversibility of DNA methylation induced by carcinogenic agents has likewise been observed due to ingestion of high-fat diets in rodents
  • the relationship between DNA methylation and gene expression is not always straightforward
  •  
    Study finds variability of methylation and some genetic expression alteration with high fat diet.  Restated, what you eat interacts with your DNA to alter genetic expression.  This has implications on initiation of therapy as well as response to therapy.
