• strength
  • While strength is the physical ability to generate a high amount of muscle force, power is the ability to generate a high amount of force in a short period of time. (acefitness.org)
  • Exercise movements performed at a steady, slow tempo can help strengthen muscles, but those strong muscles may lack the ability to express that strength instantaneously. (acefitness.org)
  • If you exercise for the purpose of improving your performance in sports such as tennis, softball, baseball, volleyball or Ultimate Frisbee, or if you want to improve your ability to perform daily tasks such as carrying a bag, caring for young children or gardening, it is important to perform exercises to improve the strength and power of the muscles of the upper back, shoulders, arms and hips.

  • The strength capability of the joint is denoted by the amount of moment that the muscle force can create at the joint to counter the external moment. (wikipedia.org)
  • Based on this model, the external moments at each joint must not exceed the muscle strength moments at that joint. (wikipedia.org)
  • capillaries
  • Type I muscle fibers are surrounded by more capillaries, which means muscles get more blood flow and transfer, and contain higher concentrations of myoglobin (pictured right). (breakingmuscle.com)
  • Your muscles are saturated with tiny thread-like veins called capillaries, which allow oxygen and other essential substances to diffuse from your blood and into your muscles. (livestrong.com)
  • To facilitate this increased exchange of gasses, your capillaries and other blood vessels in and around your muscles expand during exercise. (livestrong.com)
  • movements
  • Fig. 1 diagrams the major intracellular movements of Ca 2+ that take place during a twitch. (rupress.org)
  • While the hips aren't necessarily an upper-body muscle, optimal power for many upper-body movements-from throwing a ball to punching an opponent to picking up a young child-is derived from the ability of the hips to generate force, which is then transmitted and released through the shoulders and arms. (acefitness.org)
  • Moving slower in movements will help make improvements in lifts over time so you can lift more than the athlete next to you. (breakingmuscle.com)
  • adapt

  • 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)
  • 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)
  • muscular
  • High intensity training over a prolonged period of time improves the ability of a neuro muscular system to recruit a greater number of motor units (volley firing), and thus creates a greater number of muscle fibers to contract. (bodybuildingpro.com)
  • Most people who fit into this category will have a bigger skeletal and muscular structure and the appearance of larger muscles. (breakingmuscle.com)
  • The muscular system controls numerous functions, which is possible with the significant differentiation of muscle tissue morphology and ability. (lumenlearning.com)
  • The muscular system is made up of muscle tissue and is responsible for functions such as maintenance of posture, locomotion and control of various circulatory systems. (lumenlearning.com)
  • Skeletal muscle of the muscular system is closely associated with the skeletal system and acts to maintain posture and control voluntary movement. (lumenlearning.com)
  • 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)
  • high
  • Many popular high-intensity exercise programs feature jumps, hops or skips to increase power output in lower-body muscles, but omit exercises for developing upper-body power. (acefitness.org)
  • Do a complete dynamic warm-up to properly prepare your muscles before beginning the high-intensity exercises of the working sets. (acefitness.org)
  • You can do this by training your FT fibers with heavy weights and low reps, a combination of your FT and ST fibers with medium weight and reps, and your ST fibers with light weights and high reps. (facepunch.com)
  • The motor units are being recruited in an order from slow, low force to fast, high force. (wikipedia.org)
  • tissue
  • ATP is vital to all cells in the body, but in skeletal tissue it is an important aspect of the sliding filament theory, or simply put, how our muscles contract. (breakingmuscle.com)
  • Muscle tissue can be divided functionally (voluntarily or involuntarily controlled) and morphologically ( striated or non-striated). (lumenlearning.com)
  • Muscle is a highly-specialized soft tissue that produces tension which results in the generation of force. (lumenlearning.com)
  • Numerous myocytes make up muscle tissue and the controlled production of tension in these cells can generate significant force. (lumenlearning.com)

  • Smooth muscle tissue is associated with numerous organs and tissue systems, such as the digestive system and respiratory system. (lumenlearning.com)
  • MyoD is expressed at extremely low and essentially undetectable levels in quiescent satellite cells, but expression of MyoD is activated in response to exercise or muscle tissue damage. (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)
  • 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)
  • Three homologous genes have evolved in vertebrates, encoding three muscle type specific isoforms of TnT. (wikipedia.org)
  • Protein sequence alignment demonstrated that TNNT1 genes are highly conserved among vertebrate species (Fig. 2), especially in the middle and C-terminal regions, while the three muscle type isoforms are significantly diverged among vertebrate species. (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)
  • refers
  • Voluntary refers to whether the muscle is under conscious control, while striation refers to the presence of visible banding within myocytes caused by the organization of myofibrils to produce constant tension. (lumenlearning.com)
