Effects of Eccentric Nordic Hamstring Exercise on Fascicle Length in Females
… exercise (NHE) may be useful for increasing fascicle length (FL) of the bicep femoris long head and reduce the risk of hamstring strain injury. Compared to changes in hamstring strength, FL has been shown to reduce the risk of injury to a greater extent. While previous studies have …

An evaluation of gastrocnemius muscle structure and function in endurance runners and low physical activity individuals
… soleus flexibility, as well as changes in the fascicle length and pennation angle. Gastrocnemius volume has not been compared in low physical activity and active participants. Physiological cross sectional area, based on volume and fascicle length measurements may also provide valuable …

Modeling Gait Muscle-Reflexes Through Hindlimb Characterization in Rodents
… to measure the electromyography, muscle fascicle length, and muscle force. We conducted rat surgeries that implanted this skin port, and used the device to collect in vivo data through various terrain during walking trials. From collaborator’s in vivo data (n = 4 rodents), we implemented …

Muscle responses to stretching and developing effective interventions in children with cerebral palsy
… musculoskeletal system such as a reduced muscle length, increased tendon length and an increase in joint stiffness are commonly treated by physiotherapy interventions such as stretching exercises. However, the effectiveness of these interventions in terms of improvements in function is of a low …

Functional Anatomy of the Anconeus: Muscle Architecture and Motor Unit Number Estimation
… the measure of the architectural variables, fascicle length (LF) and pennation angle (PA), in many human skeletal muscles in vivo. However, the functional anatomy of the anconeus has been investigated mainly from cadavers exclusively. Thus, the purpose of Chapter 2 was to evaluate, using …

The effect of vertically- and horizontally-directed plyometric exercise on sprint running performance
… index (RSI-20)) and 0.40 m (RSI-40). Muscle fascicle length (FL) and angle pennation (AP) of the GM were assessed using ultrasonography, while dual-energy x-ray absorptiometry (DEXA) was used to determine body fat percentages (BF%) and composition of the shank of the subjects’ dominant legs …

The effect of two different loading schemes and recovery types on kinematic and kinetic parameters in squat exercise
… (LLHV; 35% 1RM) loads for vastus lateralis (VL) fasciclelength, strain, strain velocity and pennation angle changes during exercise. Tenrecreationally trained men performed 10 HLLV and LLHV squat repetitions on separatedays in a counter-balanced and randomised order. Ultrasonography was used to …

Neuromuscular adaptations of joint angle-specific force change after isometric training
… cross-sectional area (CSA), muscle fascicle length (Lf) and muscle activation adaptations. For this, the validity and reliability of a two-dimensional extended-field-of-view ultrasonography (EFOV) method for measuring muscle CSA (Study 1) and Lf (Study 2) were examined. Small …

Gastrocnemius muscle structure and function in habitually resistance-trained marathon runners and traditionally running-trained marathon runners: a comparative analysis
… Muscle architecture measurements, including fascicle length, pennation angle, thickness and volume, were performed via imaging ultrasound. Participants were then familiarised with the physical testing procedures. In the second testing session, calf muscle flexibility and endurance were …

Performance characteristics of elite softball players: Changes and determinants of performance related to the lower body
… characteristics including muscle thickness (MT), fascicle length (FL) and pennation angle (θp). The testing sessions occurred pre, mid and post a 20 week pre/in-season training period. Changes over time were analyzed by repeated measures ANOVA. Relationship between percentage (%) change in muscle …

Modifiable risk factors of hamstring strain injury : assessment, performance and training
… increased eccentric hamstring strength and BFLH fascicle length (FL). There are several alternative training modalities, including hip dominant exercises and sprinting, which are relatively unexplored within the literature, with between just one and two previous investigations of these …
