High aromatase activity in hypogonadal men is associated with higher spine bone mineral... - 0 views

  •  
    Only abstract available here--high Estradiol:Testosterone, thus high aromatase activity, increased abdominal fat and reduced lean muscle mass.  The authors also reported an higher bone mineral density, but that pales in the comparison of the metabolic dysfunction of high fat and low muscle mass causes.

Effects of Resistance Training on Testosterone Metabolism in Younger and Older Men. - P... - 0 views

  •  
    Resistance training increases Testosterone in younger and older men.  The effects in older men appears to involve more of a decreased metabolism.

  •  
    Study finds that low weight (load described in this article) high rep (described as high velocity) is better than high weight and low reps.  Only abstract available here.

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.

  •  
    Online article reviewing the physiologic adaptation of muscle to resistance training.  The author used the evidence here to point to the most productive resistance training protocol--the RE effort.  The RE effort is the high repetition, lower weight regimen.  However, the RE to failure is critical to the success of RE.
