Webb22 juni 2011 · fibres. Single muscle fibres were used with their surrounding membranes removed. These fibres will contract when exposed to calcium ions in solution. Isolated slow twitch and fast twitch fibres were tested at pH 7 and pH 6, in a range of calcium ion concentrations. Results for both types of fibre are shown in the graphs below. WebbSlow-twitch fiber cells can process greater amounts of oxygen to assist in the generation of adenosine triphosphate (ATP), the body's fuel for the production of energy. For this reason, slow-twitch fibers are relied on when the muscle must extend and contract repetitively, as in distance running or cycling events. Physiological studies confirm ...
