Biceps femoris long head sarcomere and fascicle length adaptations after 3 weeks of eccentric exercise training [PDF]

Journal of Sport and Health Science, 2022
Background: Eccentric exercise increases muscle fascicle lengths; however, the mechanisms behind this adaptation are still unknown. This study aimed to determine whether biceps femoris long head (BFlh) fascicle length increases in response to 3 weeks of ...

Myofascial Loads Can Occur without Fascicle Length Changes [PDF]

Integrative and Comparative Biology, 2018
Many studies have shown that connective tissue linkages can transmit force between synergistic muscles and that such force transmission depends on the position of these muscles relative to each other and on properties of their intermuscular connective tissues.

Muscle fascicle length adaptations to high-velocity training in young adults with cerebral palsy [PDF]

Frontiers in Sports and Active Living
IntroductionIn individuals with Cerebral Palsy (CP), both muscle cross-sectional area and fascicle length are reduced, contributing to decreased muscle strength, muscle shortening velocity and muscle mechanical power output, particularly in the ...

Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number [PDF]

Experimental Physiology, 2023
Abstract Ultrasound-derived measurements of muscle fascicle length (FL) are often used to infer increases (chronic stretch or training) or decreases (muscle disuse or aging) in serial sarcomere number (SSN). Whether FL adaptations measured via ultrasound can truly approximate SSN adaptations has not been investigated.

A Preseason Training Program With the Nordic Hamstring Exercise Increases Eccentric Knee Flexor Strength and Fascicle Length in Professional Female Soccer Players [PDF]

International Journal of Sports Physical Therapy, 2021
# Background Training programs that include the Nordic hamstring exercise (NHE) have been shown to increase eccentric knee flexor strength and biceps femoris fascicle length in male athletes. However, the effect of NHE on female athletes remains unknown.

TTN genotype is associated with fascicle length and marathon running performance [PDF]

Scandinavian Journal of Medicine & Science in Sports, 2017
Titin provides a molecular blueprint for muscle sarcomere assembly, and sarcomere length can vary according to titin isoform expression. If variations in sarcomere length influence muscle fascicle length, this may provide an advantage for running performance. Thus, the aim of this study was to investigate whether the titin (TTN) rs10497520 polymorphism

In vivo gastrocnemius muscle fascicle length in children with and without diplegic cerebral palsy [PDF]

Developmental Medicine & Child Neurology, 2007
The effect of spastic cerebral palsy on in vivo gastrocnemius muscle fascicle length is not clear. Similarity of fascicle lengths in children with diplegia and typically developing children, but shortening of fascicle lengths in the paretic legs of children with hemiplegia compared with the non‐paretic legs, are both reported.
