Answer:The sliding filament model of muscle contraction, put forward by Hugh Huxley and Jean Hanson in 1954, is 60 years old in 2014. Formulation of the model and subsequent proof was driven by the pioneering work of Hugh Huxley (1924–2013).

They speed up your heart rate and get your body loosened up for further exercises
I believe the correct answer would be actin filaments. These are polmers that are linear with G-actin as subunits that attaches ith myosin heads during the skeletal muscle contraction. They are necessary for cell shape, adhesion and contraction.
