Complex muscle architecture described with diffusion weighted MRI
… complex array of fiber orientations exhibited by muscles such as the tongue, esophagus, and heart, enable function beyond basic pulling. Among other things, the presence of crossing geometry adds the ability to push by bi-directional contraction causing expansion in the orthogonal direction. …

Muscle Architecture and Structural Model of the Human Tongue
… and respiration. It is mainly composed of muscles, which have complex bundle arrangement and interdigitation among them. The knowledge of three-dimensional muscle architecture is critical for understanding the complicated motor functions of human tongues. The present study used …

Functional Anatomy of the Anconeus: Muscle Architecture and Motor Unit Number Estimation
Exploring muscle architecture in vivo and estimating the number of MUs in the human anconeus muscle have important implications related to the neuromuscular function of this muscle as a model for study in health and disease. The two studies presented in this thesis investigate the functional …

Impaired metabolism in X-linked muscular dystrophy: experimental evaluation of potential therapies to improve calcium regulation, bioenergetics and muscle architecture
… (DMD) is a severe and progressive skeletal muscle wasting disease characterised by [Ca2+]-induced hyper-catabolism, and subsequently, a higher demand for energy production to modulate intracellular Ca2+ homeostasis, and protein degradation and synthesis pathways. The broad aim of this thesis …

Performance characteristics of elite softball players: Changes and determinants of performance related to the lower body
… deterministic relationship. Study 3: Changes in muscle architecture and performance during a competitive season in female softball players The purpose of this research was to (1) examine the performance changes that occur in elite female softball players during 20 weeks of concurrent softball …

Long term adaptations and mechanisms of different protocols of ''concurernt'' training in recreationally trained male adults.
… structural (body composition and muscle architecture), and mechanical long-term adaptations between the three different concurrent training methods; Traditional Concurrent Training (TCT), Sprint Interval Training (SIT), and High-intensity Resistance Circuit-based training (HRC) in …

Comparisons of countermovement jump and isokinetic performance in youth athletes: maturation and early sport specialization considerations
… countermovement jump (CMJ)performance and muscle architecture in adolescents. Eight ultrasound variables, nine CMJ variables and six isokinetic variables were found to be reliable among this subject group and were subsequently used in the remaining studies. Study 2 investigated the …

Force Dynamics of the Rat Lateral Gastrocnemius Muscle after Undergoing Sensory Protection
… the reinnervation of a motor-denervated muscle with a sensory nerve, has shown promise in preserving muscle function and structure. This thesis investigates the impact of sensory protection on the force dynamics and muscle architecture of the lateral gastrocnemius muscle in a rat animal …

An evaluation of gastrocnemius muscle structure and function in endurance runners and low physical activity individuals
… runners. The gastrocnemius is the main muscle used for propulsion in running, and may be at risk for injury due to its morphology. In previous studies, changes in the morphology and architecture of the gastrocnemius muscle have been evident following training, but it is unclear whether …

THE ROLE OF INNERVATION IN ENGINEERED MUSCLE
Skeletal muscle injuries span a wide spectrum, from minor strains to devastating traumatic events, and represent a significant clinical challenge worldwide. Millions of individuals experience severe muscle deficits each year, including volumetric muscle loss (VML) resulting from ballistic trauma, …

Integrins in muscle disease and repair
… an important role in maintaining adult skeletal muscle integrity and like dystrophin, provides anchorage and bidirectional signaling as a laminin receptor. The expression of α7β1 integrin was upregulated upon dystrophin deficiency arguing for the molecular compensation and thus considered as …

THE IMPACT OF CONCURRENT-TRAINING ON THE PHYSIOLOGICAL ADAPTATIONS TO SPORT SPECIFIC EXERCISE IN ELITE FOOTBALLERS
… weeks 4 to 10 may not be optimal for longer-term muscle performance (Fleck, 1999). The secondary findings from this study demonstrated that when concurrent-training was performed on the same day, the order of aerobic and resistance exercise, the nutritional availability and the recovery period …

Modeling of Bio-inspired Jellyfish Vehicle for Energy Efficient Propulsion
… are the oldest known metazoans that swim using muscles. They are found in freshwater sources and in oceans all over the world. Over millions of years of evolution, they have adapted to survive in a given environment. They are considered as one of the most energy efficient swimmers. Owing to …

Development and application of an eccentric force-velocity profile in rugby union athletes
… former with respect to hypertrophy, strength and muscle architecture. Furthermore, the existing literature for ECC tends to emphasise heavy- or tempo-controlled exercises. Current research has suggested that relatively fast ECC may provide a superior stimulus for eliciting adaptation in measures …

The effect of vertically- and horizontally-directed plyometric exercise on sprint running performance
… body composition and gastrocnemius medialis (GM) muscle architecture. Male (n = 19) and female (n = 20) recreational athletes were recruited and stratified according to 40 m sprinting ability, then randomly allocated to one of two groups: horizontally-directed plyometric training (HT) and …

Training adaptations in lower-body muscle structure and physical performance capacities of competitive surfing athletes
… scientists’ understanding of the lower-body muscle structures related to enhanced lower-body physical capacities, and how to best evoke desirable training-specific adaptations. To address this aim, three successive steps of research were evaluated: (1) analysis of the factors related to …

Gastrocnemius muscle structure and function in habitually resistance-trained marathon runners and traditionally running-trained marathon runners: a comparative analysis
… running. Running training causes an overload on muscle and stimulates a physiological adaptation to create a training response. Specific adaptations in metabolic and physiological function of a muscle may be further achieved through specificity of exercise training. Resistance training programmes …

Effects of Eccentric Nordic Hamstring Exercise on Fascicle Length in Females
<p>The eccentric Nordic hamstring 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 …
