The energy of muscle contraction. IV. Greater mass of larger muscles
Earlier activation of the muscle while the MTU is still lengthening can allow for greater storage of elastic energy, as the tendon can store energy from external work as well as work done by the
Elastic Energy Storage and Radial Forces in the Myofilament
Energy storage in cross-bridges Strain energy storage in muscle systems is most often associated with stretched tendons or other elastic supporting materials [1,2]. In many instances, strain
Intrinsic foot muscles contribute to elastic energy storage
94 In a similar anatomical arrangement to the ankle plantar flexor muscles and Achilles tendon, 95 the FDB and AH muscles have very short muscle fibres (<25 mm) attached to long tendons 96
Contribution of elastic tissues to the mechanics and energetics of
In-series tendon can store energy from muscles during contraction of the muscles, as in frog jumping, but energy storage within intramuscular springs requires muscle lengthening, as in a
Glycogen
α(1→4)-glycosidic linkages in the glycogen oligomer α(1→4)-glycosidic and α(1→6)-glycosidic linkages in the glycogen oligomer. Glycogen is a branched biopolymer consisting of linear chains of glucose residues with an average
8.8: Carbohydrate Storage and Breakdown
Its regulation is consistent with the energy needs of the cell. High energy substrates (ATP, G6P, glucose) allosterically inhibit GP, while low energy substrates (AMP, others) allosterically activate it. Glycogen
The Development of the Locust Jumping Mechanism : II. Energy Storage
ABSTRACT. In an escape jump, the adult locust extensor tibiae muscle produces more than twice the specific energy output of the fourth instar muscle.If forced to jump repeatedly, the extensor
Muscle–spring dynamics in time-limited, elastic movements
The time available for muscles to load in-series springs is important, because stored elastic energy is proportional to force, and muscle force declines with contraction velocity ; therefore,
Twisted and coiled yarns for energy harvesting and
Despite the diversity of applications, similar fabrication methods and related mechanisms are used to provide giant, highly reversible yarn elasticity and the associated property changes that result in muscle
Movement Strategies for Countermovement Jumping
Previous studies have demonstrated an important contribution of elastic energy stored within the Achilles tendon (AT) during jumping. This study aimed to alter energy available for storage in...
Elastic energy storage in tendons: mechanical differences related to
A morphometric analysis of the digital muscles provides an estimate of maximal in vivo tendon stresses and suggests that the muscle-tendon unit of the digital flexor is designed to function
Elastic energy storage in rigored skeletal muscle cells under
The capability of heavy meromyosin (HMM) to store energy in reversible deformations has been investigated previously; yet, whether HMM is the site of most elastic energy storage in skeletal
Beyond energy storage: roles of glycogen metabolism in health
Beyond storing and supplying energy in the liver and muscles, glycogen also plays critical roles in cell differentiation, signaling, redox regulation, and stemness under various physiological and
Storage of elastic strain energy in muscle and other tissues
The elastic materials involved include muscle in every case, but only in insect flight is the proportion of the energy stored in the muscle substantial. Storage of strain energy in elastic
Energy Storage and Expenditure
Cells use fat and starch for long-term energy storage instead of ATP molecules because ATP (adenosine triphosphate) is a molecule that provides immediate energy to the cell. It is a complex carbohydrate that is
