Contractile speed
WebJan 25, 2013 · Type 2B fibers have the fastest contractile speed, the largest cross-sectional area, the highest glycogen stores and glycolytic capacity, and the lowest oxidative capacity. They are ideally suited to short, fast bursts of power such as jumping or sprint racing. Type 2A fibers are intermediate in contractile speed and metabolic properties ... WebJan 14, 2003 · A spinal cord injury usually leads to an increase in contractile speed and fatigability of the paralysed quadriceps muscles, which is probably due to an increased expression of fast myosin heavy chain (MHC) isoforms and reduced oxidative capacity. Sometimes, however, fatigue resistance is maintained in these muscles and also …
