Musculoskeletal modelling of an ostrich (Struthio camelus) pelvic limb: influence of limb orientation on muscular capacity during locomotion [PDF]

, 2015
We developed a three-dimensional, biomechanical computer model of the 36 major pelvic limb muscle groups in an ostrich (Struthio camelus) to investigate muscle function in this, the largest of extant birds and model organism for many studies of locomotor

Impact of 6-Week Combined Gym and Climbing Training on Handgrip Strength and Arm Size—GRIP-6 Study

Journal of Functional Morphology and Kinesiology
Background: Climbing and strength training are among the most popular types of sports among recreational athletes. However, many newcomers quickly lose motivation and abandon training due to a lack of visible and athletic progress.

Correlation between Mid Upper Arm Muscle Area/Size and Muscle Strength

Althea Medical Journal, 2016
Background: Muscle area/size reflects the true magnitude of muscle tissue changes. Muscle strength is an active tension generated by muscle that depends on its capacity to exert force on an object. The relation between the quantity of muscle area and the

Non-linear Scaling of Passive Mechanical Properties in Fibers, Bundles, Fascicles and Whole Rabbit Muscles

Frontiers in Physiology, 2020
Defining variations in skeletal muscle passive mechanical properties at different size scales ranging from single muscle fibers to whole muscles is required in order to understand passive muscle function.

Longitudinal RNA-Seq analysis of acute and chronic neurogenic skeletal muscle atrophy. [PDF]

, 2019
Skeletal muscle is a highly adaptable tissue capable of changes in size, contractility, and metabolism according to functional demands. Atrophy is a decline in mass and strength caused by pathologic loss of myofibrillar proteins, and can result from ...

Towards defining muscular regions of interest from axial magnetic resonance imaging with anatomical cross-reference: a scoping review of lateral hip musculature

BMC Musculoskeletal Disorders, 2022
Background Measures of hip muscle morphology and composition (e.g., muscle size and fatty infiltration) are possible with magnetic resonance imaging (MRI).

Resistance Training Using VAriable Resistance Suit (VARS) Increased Isometric and Isokinetic Muscle Strength

IEEE Transactions on Neural Systems and Rehabilitation Engineering
While resistance training promotes muscle hypertrophy and strength, accessibility of equipment is a barrier. This study evaluated a wearable VAriable Resistance Suit (VARS) as a novel and alternative method to achieve muscle strength improvement.

Muscle hypertrophy and muscle strength: dependent or independent variables? A provocative review

European Journal of Translational Myology, 2020
The question whether the muscle hypertrophy induced by resistance training, hormone administration or genetic manipulation is accompanied by a proportional increase in muscle strength is still open.

Oral fucoidan improves muscle size and strength in mice

Physiological Reports, 2021
Fucoidan is a sulfated polysaccharide found in a range of brown algae species. Growing evidence supports the long‐term supplementation of fucoidan as an ergogenic aid to improve skeletal muscle performance.

In vivo myosin step-size from zebrafish skeletal muscle [PDF]

Open Biology, 2016
Muscle myosins transduce ATP free energy into actin displacement to power contraction. In vivo, myosin side chains are modified post-translationally under native conditions, potentially impacting function. Single myosin detection provides the ‘bottom-up’
