- - - - proteins are the primary structural components of cells
        
        proteins build and repair cells, including the muscle cells damaged when exercising to the point of momentary fatigue
        
        Protein should comprise 15-30% of an individual’s daily caloric intake, depending on activity levels
        
        For muscle growth, consume foods that are high in protein
        
        lean meats, fish, eggs, chicken or milk. Soy is the only form of plant-based protein that contains all eight essential amino acids
- - - - myosin head binds to actin and breaks down ATP
      - releases energy that pulls the actin filaments along
        
        actin and myosin filaments slide past one another
        
        muscle contracts
      - In skeletal muscle, the contraction is started by a rise in the concentration of calcium ions
        
        triggered by the arrival of a neurotransmitter
        
        calcium ions, in turn, interact with two other proteins, troponin and tropomyosin.
- - - - Each bundle of muscle fiber is called a fasciculus
        
        surrounded by a layer called the perimysium
      - Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.
      - A muscle cell (fiber) is made up of myofibrils, or bundles of protein
        
        actin
        
        myosin
- - - - Quinoa.
      - Tofu
      - Mushrooms
      - Cottage cheese
      - Fish
      - Lentils
      - Quorn
      - Edamame beans
- - - - swimming, walking, playing catch, running can all be easier ways to begin exercise on fatigued and weak muscles
        
        increase intensity and longevity of physical exercise and introduce high intensity training as well as circuit training
