Effects of Eccentric Nordic Hamstring Exercise on Fascicle Length in Females
… and included: bicep femoris FL and pennation angle (measured via 2D ultrasound), lower body isokinetic strength, and countermovement jump height. Independent samples Mann-Whitney U test were used to assess whether the change in the outcome variables pre-to-post intervention were …

An evaluation of gastrocnemius muscle structure and function in endurance runners and low physical activity individuals
… 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 information about the …

Elastografia Supersonic Shear Imaging em músculo esquelético: análise da anisotropia do músculo gastrocnêmio lateral e relação entre a angulação de fibras musculares e sintéticas e o módulo de cisalhamento
… Shear Imaging (SSI) elastography. As the pennation angle (PA) varies between muscles, individuals and dynamic conditions, its relation with the μ is not defined. The aim of this study is to explore the relation between synthetic and muscles fibers, i.e., PA with μ. Additionally, evaluate …

Gastrocnemius muscle structure and function in habitually resistance-trained marathon runners and traditionally running-trained marathon runners: a comparative analysis
… 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 assessed; and …

The impact of cryotherapy versus placebo interventions on recovery following strenuous exercise, and adaptations to resistance training
… time, and diminished increases in muscle fibre pennation angle compared to a placebo. CWI may have enhanced neural adaptations, although there were no clear functional improvements compared to placebo. Lastly, decrements in markers of bone and collagen turnover were more pronounced in the CWI …

The effect of two different loading schemes and recovery types on kinematic and kinetic parameters in squat exercise
… (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 recordVL fascicle length, strain, strain …

Sex differences in the neural control of muscle
… from neural compensation for a less optimal pennation angle or a tendency towards greater joint laxity. Higher motor unit discharge rates and incidence of doublets may increase twitch force summation leading to a reduction in FS. Thus, biomechanical, not inherent sex-differences in neural …

Investigation of the impact of compression garments on endurance running performance and exercise induced muscle damage in the lower leg
… gastrocnemius mean muscle thickness and mean pennation angle, mean CMJ height and estimated peak power output nor in race performance) between the experimental and control groups. Selected pain ratings were statistically significantly worse in the experimental group. Muscle thickness and …

Functional Anatomy of the Anconeus: Muscle Architecture and Motor Unit Number Estimation
… 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 ultrasonography, the degree …

Performance characteristics of elite softball players: Changes and determinants of performance related to the lower body
… 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 architecture variables …
