The optimum load range for muscle growth range is from 60 to 85% of the maximum weight, which usually corresponds to the performance of 6 to 20 reps with the weight of the exercise performed to muscular failure (that is, until the moment we are not able to do even one more repetitions without rest).
However, the same load is not sufficient to stimulate the muscles to increase - they must perform a specific job metabolic. As a result of subjecting the muscle load over time worsen biochemical changes which the best known is the effect of the formation of lactic acid.Information Resource By somanabolic muscle maximizer
To change this could occur, the minimum duration of the exercise (one set) should be 20 seconds, and optimally from 20 to a maximum of 60 seconds. Although there is no big deal for beginners, but it may be good to know that the series lasting from 5 to 20 seconds (1-5 reps on the assumption that repetition takes 3-5 seconds).
It affects mainly the improvement of labor force by improving the central nervous system, Series 20-45 seconds (5-15 reps) stimulate muscle growth primarily by affecting the muscle fibers type IIa and IIb, and a series of 45-60 second build strength mainly affects glycogen to increase capacity.
The number of mitochondria in muscle cells and increases the volume of the muscle mass). Not without significance is also what occurs during a series of history, and more specifically what type of traffic (work) do muscles.
