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 ...

Fascicle Length Change of the Human Tibialis Anterior and Vastus Lateralis During Walking

Journal of Orthopaedic & Sports Physical Therapy, 2007
A single-group descriptive experimental design.To determine the fascicle length change in the tibialis anterior (TA) and the vastus lateralis (VL) muscles during walking.The length of the muscle fibers during isometric actions and during dynamic functional activities is affected by the compliance of the tendon and aponeurosis.

Effects of dynamic resistance training on fascicle lengthand isometric strength

Journal of Sports Sciences, 2006
The aims of this study were to assess changes in muscle architecture, isometric and dynamic strength of the leg extensor muscles, resulting from dynamic resistance training, and the relationships between strength and muscle architecture variables. The participants (n = 30) were randomly assigned to one of two groups.

In vivo operational fascicle lengths of vastus lateralis during sub-maximal and maximal cycling

Journal of Biomechanics, 2010
Instantaneous contractile characteristics of skeletal muscle, during movement tasks, can be determined and related to steady state mechanical properties such as the force-length relationship with the use of ultrasound imaging. A previous investigation into the contractile characteristics of the vastus lateralis (VL) during cycling has shown that ...
