Biceps femoris fascicle length during passive stretching

Journal of Electromyography and Kinesiology, 2018
The purpose of this study was to quantify the relative changes in fascicle (FL) and muscle-tendon unit (LMTU) length of the long head of the biceps femoris (BFlh) at different combinations of hip and knee joint positions. Fourteen participants performed passive knee extension trials from 0°, 45° and 90° of hip flexion.

Shorter muscle fascicle operating lengths increase the metabolic cost of cyclic force production

Journal of Applied Physiology, 2022
During locomotion, active muscles undergo cyclic length-changing contractions. In this study, we isolated confounding variables and revealed that cyclically producing force at relatively shorter fascicle lengths increases metabolic energy expenditure. Therefore, muscle fascicle operating lengths likely have a measurable effect on the metabolic energy ...

APONEUROSIS LENGTH AND FASCICLE INSERTION ANGLES OF THE BICEPS BRACHII

Journal of Mechanics in Medicine and Biology, 2002
Magnetic resonance images and ultrasound images were used to examine the architecture of the distal biceps brachii muscle in 12 unimpaired subjects. The distal biceps brachii tendon continued as an internal aponeurosis that spanned 34± 4% of the length of the biceps brachii long head muscle on average. The distal muscle fascicles inserted at angles to

Biceps femoris long head muscle fascicle length does not differ between sexes

Journal of Sports Sciences, 2019
Hamstring strain injury (HSI) rates are higher for males vs. females. This cross-sectional study investigated if inherent differences in biceps femoris long head (BFLH) fascicle length (Lf) exist between recreationally active males and females (i.e., individuals without specific training practice history).

Test-retest reliability of gastrocnemius medialis fascicle force-length relationship

Journal of Biomechanics
Fascicle force-length relationship is one major basic mechanical property of skeletal muscle, subsequently influencing movement mechanics. While force-length properties are increasingly described through ultrafast ultrasound imaging, their test-retest reliability remains unknown.

Fascicle length of leg muscles is greater in sprinters than distance runners

Medicine & Science in Sports & Exercise, 2000
The purpose of this study was to compare architectural characteristics of leg muscles of sprinters and distance runners.Skeletal muscle architectural characteristics were studied in 23 elite male 100-m sprinters (SPR, 10.0-10.9 s for 100 m), 24 elite male distance runners (DR, 13.5-14.5 min for 5000 m), and 24 untrained male controls.

Muscle Oxygenation and Fascicle Length During Passive Muscle Stretching in Ballet-Trained Subjects

International Journal of Sports Medicine, 2011
Muscle stretching transiently decreases muscle-blood flow corresponding to a muscle extension. It may disturb a balance between muscular oxygen demand and oxygen supply to muscles and reduce muscle oxygenation. However, muscle-stretching training may improve blood circulatory condition, resulting in the maintained muscle oxygenation during muscle ...

Sprint performance is related to muscle fascicle length in male 100-m sprinters

Journal of Applied Physiology, 2000
The purpose of this study was to investigate the relationship between muscle fascicle length and sprint running performance in 37 male 100-m sprinters. The sample was divided into two performance groups by the personal-best 100-m time: 10.00–10.90 s (S10; n = 22) and 11.00–11.70 s (S11; n = 15).

Automatic Fascicle Length Estimation on Muscle Ultrasound Images With an Orientation-Sensitive Segmentation

IEEE Transactions on Biomedical Engineering, 2015
The fascicle length obtained by ultrasound imaging is one of the crucial muscle architecture parameters for understanding the contraction mechanics and pathological conditions of muscles. However, the lack of a reliable automatic measurement method restricts the application of the fascicle length for the analysis of the muscle function, as frame-by ...
