Tendon: connective tissue connects overall muscle to the bone itself

Fascicle: Group of fibers

Perimysium: connective tissue surrounding the whole group of fibers

Endomysium: connective tissue surrounding each individual fiber

  • Muscle cells have many of the same organelles present in other cells
  • However, muscle cells are multinucleated, unlike other cells.
  • Skeletal muscles are striated (striped) w/ alternating light and dark bonds
  • Each individual muscle fibers long, thin, cylinder that generally extends the length of the muscle
  • Millions of rubber bands stretching

Muscle Cell

  • In each individual muscle cell, there are its own contractile proteins (sarcomere)
  • Contractile Proteins:

                   ACTIN: thin filament (proteins)- troponin/ tropomyosin

                   MYOSIN: thick filaments (sarcomeres are divided by z-lines

  • Major components that create a shortening in the cell

Brain tells muscle to move in by sending nerve impulses through the nervous system to the neuromuscular junction

  • Neuromuscular junction: site where nervous system innervate a muscle

Skeletal Muscles:

  • Any muscle in the body that you can actively move to produce motion

 (ie.) arm: biceps mate arm move

  • The ability of the muscle to provide force and movement for physical activity

  • Any type of training program has the primary goal of improving the functional capability of the exercising muscle

                 -   Different sports use your same muscles in different ways as well as using

                     different muscles all together

  • More than 400 muscles in the body
  • Should constitute about 40-50% of total body weight

Function:

  1. Produces force when your muscles contract  for locomotion and breathing
  2. Produces force of postural support- lower back support
  3. Heat production during cold stress

Sliding Filament Theory

  • Explains the process of muscle contraction

  1. Muscle fibers contract by a shortening of their myofibrils due to actin sliding over the myosin (protein filament sliding over another protein filament)
  2. Distance from z-line to z-line reduces
  3. Myosin has a bunch of arms/cross bridges that reach out and attach to the astin.
  4. Myosin then pulls the actin together

Fiber Types:

  • All muscle fibers function in a similar manner although some have different contractile and metabolic properties
  • Not all fibers are the same (metabolic properties) -types of contractions it can produce
  • Some are more suited for aerobic work and some for cinearobic work
  • Most muscles contain an equal # of both
  • Fiber type can be influenced by: genetics, hormones, and training

Type I: Fibers (Slow twitch)

  • Contains large #s of oxidative enzymes and mitochondria
  • Surrounded by numerous capillaries (means it can deliver more oxygen)
  • Endurance oriented (more efficient)
  • Produces less intense contractions over time (less tension)

Type II fibers (fast twitch)

Type II A

  • Mixture of type I and type II fibers (sits in the middle)

Type II B

  • Relatively small number of mitochondria because they don’t use oxygen to produce energy
  • High power/ high tension contractions (powerful)
  • Low efficiency -doesn’t last long

Rigorous training can result in alteration of muscle fiber

  • Some people believe in you can’t change type/into type II and vice verse
  • Some people believe that you can indeed change them through training

In order for a muscle to contract certain things need to be present:

  • Energy: comes from the breakdown of ATP
  • ATP: universal energy donor

Steps of How a muscle contracts

  1. Brain signals muscle saying “I need you to move’
  • Nerve impulse travels and arrives at neuromuscular junction

  1. Causes a release of calcium in the muscle cells that bind with troponin (protein of actin)
  • Warning muscle to get ready , you’re about to move

  1. When bond is made, it signal tropomyosin to open up binding sites for myosin to attach to actin

         - actin in a resting state is like a greased pole

         - when bond forms, actin becomes ridged with hand hold for myosin to grab onto

  1. Strong binding state has occurred
  2. ATP is then released as energy resulting in movement of the cross bridges/muscle contraction

  • This cycle can be repeated as long as calcium is available to bind with troponin and ATOP available for energy
  • Contraction stop signal is the removal of calcium. When it is gone, tropomyosin will then recover the active binding sites

       

Muscle Contraction:

3 types:

  • Isometric: muscle contraction w/ no movement
  • Isotonic: muscle contraction w/movement
  • Concentric: muscle shortens during contraction
  • Eccentric: muscle lengthens during contraction
