Week 1 Study Questions Flashcards
. In the context of resistance training, why is it advantageous to exercise muscles that live on the ascending limb of the f-l curve through the greatest possible range of motion?
Because some muscles are active well into the ascending portion of the curve. This means that the muscle can get shorten too much and experience active insufficiency.
explain the reasons why torque varies as it does throughout the range of motion.
because the muscle changes in length and muscle activation varies at different lengths
What is the underlying principle of variable resistance strength training machines? Do they deliver on their promise of enhancing the benefits of resistance training in comparison to conventional training with fixed (invariable) weights?
- Resistance training is based on the principle that muscles of the body will work to overcome a resistance force when they are required to do so.
- Resistance training increases muscle strength by making your muscles work against a weight or force.
- Yes, resistance training results in the muscles being under constant tenson which result in muscle growth
Why must you be significantly stronger than your opponent to win an arm wrestle?
being stronger allows for more force to be generated. Which results in a greater torque output
Describe the effects of aging on the force-velocity relationship as detailed by Raj et al (2010) in this week’s prescribed reading. Pay particular attention to the mechanisms that mediate the deleterious changes in muscle function.
aging is associated with a downward and leftward shift of the f–v curve (as indicated by arrow 1 in Fig. 1) due the lower force-producing capacity of muscles across all contraction speeds.
