Muscle fascicle length increases more after eccentric training than after concentric training (Ema et al. 2016), probably through a larger increase in the number of sarcomeres in series within the myofibrils of a muscle fiber (Brughelli & Cronin, 2007; Butterfield, Muscle fascicle length increases more after eccentric training than after concentric training (Ema et al. 2016), probably through a larger increase in the number of sarcomeres in series within the myofibrils of a muscle fiber (Brughelli & Cronin, 2007; Butterfield, muscle fiber (Brughelli & Cronin, 2007; Butterfield, 2012).
Thus, although there are only three isoforms expressed in human skeletal muscle, there are many more hybrid muscle fiber types comprising muscle fibers with several different isoforms within the same muscle fiber (see review by Scott et al. 2001).

However, this has been strongly criticised (Vigotsky et al. 2015a; Vigotsky et al. 2015b), not least because the electric potential difference within muscles, which is measured by EMG amplitude, is a function of both muscle fiber recruitment and motor unit firing frequency, as well as of several additional peripheral factors (Kuriki et al. 2012).
When sarcomeres attempt to reduce length by increasing the amount of actin and myosin filaments that overlap, this produces tensile force within the muscle fiber that ultimately leads to muscle contractions.
Although in its traditional form, it has always failed to explain some of the fairly fundamental behaviors of muscle contractions, including the history dependence of force production, many researchers believe that it still provides the best explanation for the mechanism by which sarcomeres shorten in order to create tensile force within a muscle fiber.
It is thought that this phenomenon is related to the extent to which the individual sarcomeres within the muscle fiber are overlapping (Brughelli & Cronin, 2007).
The length - tension relationship is the degree to which the sarcomeres within the muscle fibers overlap.
