Resistance Training Flashcards
Why does resistance training increase strength
Due to more synchronous recruitment so hypertrophy and therefore increased strength
How can strength gains occur
greater motor unit recruitment, more synchronous motor unit recruitment
How does greater motor unit recruitment increase strength
Neural drive increases during max contraction, motor unit firing increases, inhibitory impulses decreases
What is autogenic inhibiton
golgi tendon inhibits muscle contraction if tendon tension is too high to prevent damage to muscle and bone
What is transient hypertrophy
Pump. Edema formation from plasma
What is chronic hypertrophy
Fibre hypertrophy and/or fibre hyperplasia
How does training affect protein synthesis/degradation
During synthesis decreases and degradation increases. After synthesis increases and degradation decreases
Why is hypertrophy maximised by eccentric training
The increases force by disrupting the sarcomere Z-lines which leads to protein remodelling and overreaching
What is fibre hyperplasia
fibre splitting, each half grows into size of parent fibre
What do damages muscle cells attract and what do they do
Neutrophils. these release radicals. These and welling stimulate pain nerves, macrophages remove cell debris
How can you reduce DOMS
minimise eccentric work early in training, start with low intensity and gradually increase
