Document Summary

How is it possible: excitation of contralateral motor cortex, spinal mechanism. Application & misapplication of size principle for rt: It means effort should be maximal: the greater the stimulus (internal ap generated by brain), the greater recruitment of mu through size principle; each individuals effort determines motor neuron activation. Muscle adaptations to resistance training: lecture 6: the fundamental neuromuscular concept is that all voluntary muscle actions initiate in the brain and ap"s are generated. Male, 70kg, with a leg press 1-rm= 170kg. Very light load: 30% of 1-rm = 51 kg = 73% of his body weight. The loading of muscles is still significant. Improved strength/power results from high intensity/low volume training (~5-6 rm) Improved hypertrophy results from lower intensity/higher volume training (~10-12 rm) Intermediate load/repetition: 9-11rm/set (int group) training on strength (1rm), muscle cross sectional area (csa), fibre types, 9 weeks, 2 to 3 times a week, in untrained young male subjects.
