Nosaka et al found that the “repeated bout effect” created by eccentrics contractions can last from 6-9 months. Although the mechanisms for the long lasting effect are not understood, the effects are measureable and imply that eccentric exercises can create both rapid (Clarkson et al) and long lasting effects. The degree of muscle damage did not have an influence on the amount of time the effects lasted which makes it probable that the long lasting effects would also take place (duration unknown) with eccentric exercises performed in the shortened ranges where less muscle damage occurs. It should also be noted that significant changes in RANG, FANG and ROM were created by the bouts. Although immediate ROM decreases are common following eccentrics through the lengthened range, the long lasting effects of the strength gains had an opposite effect after the period of recovery. Again this supports Cheng and Rice’s conclusion that agonist strength is required for moving through the entire available ROM.
