  • pelvic
  • Tight pelvic muscles are a leading cause of sex pain, according to experts. (go.com)
  • The pelvic floor is all the muscles, plus the nerves controlling the muscles, plus the tissues -- called fascia -- that connect everything together, plus the ligaments that link bone to bone and bone to organ that are attached to the front, back, and sides of the pelvis, from the pubic bone in the front of the body all the way back to the tailbone. (go.com)
  • These muscles, nerves, tissues, and ligaments sheathe the floor of the pelvis and together act like a sling or hammock to support the pelvic organs -- the urinary tract, digestive tract, and reproductive organs -- including the bladder, the uterus (or in men, the prostate), and the colon. (go.com)
  • anaerobic
  • Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30-35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. (wikipedia.org)
  • adapt
  • According to the principle of specificity, muscles grow and adapt in response to the applied forces used during exercise. (acefitness.org)
  • During this activated state, the muscles have a tremendous ability to adapt. (wikipedia.org)
  • ratio
  • Each person has a specific ratio of FT to ST fibers. (blogspot.com)
  • These fibers provide the capability to alter our original genetic FT/ST ratio. (blogspot.com)
  • increasing muscle CSA will likely increase raw power but now automatically power to weight ratio. (starbike.com)
  • This ratio is believed to have genetic origins, though some assert that it can be adjusted by muscle training. (wikipedia.org)
  • synapse
  • The specific patterning of synapse development at the neuromuscular junction shows that the majority of muscles are innervated at their midpoints. (wikipedia.org)
  • The characteristics of PSCs are based on both external synaptic properties and internal glial properties, where the internal characteristics of PSCs develop based on the associated synapse, for example: the PSCs of a fast-twitch muscle fiber differ from the PSCs of a slow-twitch muscle fiber even when removed from their natural synaptic environment. (wikipedia.org)
  • Gene
  • Although MyoD marks myoblast commitment, muscle development is not dramatically ablated in mouse mutants lacking the MyoD gene. (wikipedia.org)
  • The MYLK2 gene expresses skMLCK more prevalently in fast twitch muscle fibers as compared to slow twitch muscle fibers. (wikipedia.org)
  • Sequence and epitope conservation studies suggested that genes encoding the muscle type specific TnT and TnI isoforms may have evolved from duplications of a fsTnI-like-fsTnT-like gene pair. (wikipedia.org)
  • In mammalian and avian species, TNNT1 gene has a total of 14 exons, among which exon 5 encoding an 11-amino acid in the N-terminal region is alternatively spliced, generating a high molecular weight and a low molecular weight slow TnT splice forms (Jin, Chen et al. (wikipedia.org)
  • This gene expression is limited to skeletal muscle. (wikipedia.org)
  • Studies have linked the fiber twitch type with ACTN3, i.e. fast twitch fiber abundant individuals carry the non-mutant gene version. (wikipedia.org)
  • phenotype
  • Consistent with the recessive phenotype, the truncated ssTnT is incapable of incorporation into the myofilaments and completely degraded in muscle cells. (wikipedia.org)

  • Agrin binds to a muscle-specific kinase (MuSK) receptor in the post-synaptic membrane, and this in turn leads to downstream activation of the cytoplasmic protein Rapsyn. (wikipedia.org)
  • tissues
  • Setdb1 appears to be necessary to maintain both MyoD expression and also genes that are specific to muscle tissues because reduction of Setdb1 expression results in a severe delay of myoblast differentiation and determination. (wikipedia.org)
  • oxygen
  • Myoglobin binds to oxygen and acts as a muscle reservoir for oxygen when the blood does not supply an adequate amount, so you can think of it as a storage center for oxygen. (breakingmuscle.com)
  • High expression levels of C9ORF3 is positively correlated with maximal oxygen uptake (VO2 max) and the amount of "slow-twitch" type 1 muscle fibers. (wikipedia.org)
  • genes
  • Sustained MyoD expression is necessary for retaining the expression of muscle-related genes. (wikipedia.org)
  • KAP1 is localized at muscle-related genes in myoblasts along with both MyoD and Mef2 (a myocyte transcription enhancer factor). (wikipedia.org)
  • The consequence of this coactivator/corepressor recruitment is silenced promoting regions on muscle genes. (wikipedia.org)
  • Three homologous genes have evolved in vertebrates, encoding three muscle type specific isoforms of TnT. (wikipedia.org)
  • The ability to gain muscle also varies person to person, based mainly upon genes dictating the amounts of hormones secreted, but also on sex, age, health of the person, and adequate nutrients in the diet. (wikipedia.org)

  • The motor units are being recruited in an order from slow, low force to fast, high force. (wikipedia.org)
  • patterns
  • Coupled with the fact that AChR density is the result of axonal contact instead of the cause, the structural patterns of muscle fibers can be attributed to both myotatic growth as well as axonal innervation. (wikipedia.org)
  • force
  • Though good running form is useful in increasing speed, fast and slow runners have been shown to move their legs at nearly the same rate - it is the force exerted by the leg on the ground that separates fast sprinters from slow. (wikipedia.org)
