Sentences with phrase «shorter fascicle»

Comparisons with other muscles have demonstrated that the gluteus medius contains shorter fascicle lengths than many of the others in the lower body, although not the very shortest, but this is a function of its overall size (Ward et al. (2009).

Its muscle architecture demonstrates that its role is largely one of joint stabilisation, with a very large physiological cross-sectional area (comparable to the gluteus maximus), a very high pennation angle (parts reach 45 degrees) and a comparatively short fascicle length.

Not exact matches

Therefore, it appears that the fascicle length of the calf muscles varies with the lateral gastrocnemius displaying the longest fascicle length, and the soleus the shortest.

However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).

Both short and long heads have relatively large physiological cross sectional areas in comparison to other muscles of the upper body but similar fascicle lengths.

Both the short and long head have relatively large PCSA in comparison to other muscles of the upper body, but similar fascicle lengths.

The reason for the difference between the changes in joint angle - specific strength and the changes in joint angle - specific neural drive is that both peripheral and central factors are operating, and the impact of joint angle - specific neural drive is greater after training at short muscle lengths, while the impact of peripheral factors (like regional muscle size and / or muscle fascicle length) are greater after training at long muscle lengths.

The adductor magnus, adductor longus, adductor brevis and pectineus display similar fascicle lengths, while the gracilis is much longer and the obturator externus is much shorter.

Interestingly, the Nordic curl produces greater increases in muscle fascicle length and preferential biceps femoris (short head) and semitendinosus hypertrophy compared to hip extension - based hamstrings exercises (Bourne et al. 2016).

Even so, the fascicle lengths are considered by some researchers to be quite short in comparison with those of other, similarly large muscles (Fung et al. 2009), which may mean that when the muscle is stretched in a bench press or similar movement, it could be prone to strain damage (Wolfe et al. 1992; Fung et al. 2009).

Comparing the effects of eccentric training at long and short muscle lengths, Guex et al. (2016) found that muscle fascicle length increased in both groups, but the increase was greater in the group that trained at long muscle lengths than in the group that trained at short muscle lengths (9.3 % vs. 4.9 %).

For example, individuals who have shorter and more pennated fascicles are at greater risk of hamstring strain injury (Silder et al. 2010; Timmins et al. 2015a; Timmins et al. 2015c).

In the long muscle length group, muscle fascicle lengths increased 23 ± 5 %, while in the short muscle length group, muscle fascicle length only increased by 10 ± 2 % over the same period.

It is possible that the different regional hypertrophy observed after training at long or short muscle lengths could in fact be closely related to the changes in muscle fascicle length, because changes in muscle fascicle length have been linked to greater increases in muscle size in the distal regions of the muscle (Franchi et al. 2014).

The anterior deltoid appears to be shortest in fascicle length and largest in pennation angle.
