    Heb ik na elke training die een beetje noemenswaardig is verlopen..
    In adaptation we trust

    Deadlift 285 kilo
    Squat 230 kilo
    Bankdrukken 137.5 kilo
    Powerlift totaal 652.5 kilo

      Ik heb het ook altijd na het trainen, heeft bij niets met voeding te maken hoor.
      Ik denk eerder dat het met het zenuwstelsel te maken heeft.
      Door harde trainingen krijgt deze flink wat ''klappen'' te voorduren.

          Scientific American Magazine Explains Why Your Muscles Tremble After Exercise

          Loren G. Martin, professor of physiology at Oklahoma State University in Tulsa, responds:
          "Let's start by examining what happens when you exercise. In skeletal muscle, the cells never contract individually. Rather they contract as groups of muscle cells that are collectively connected to a motor nerve originating in the spinal cord; the combination of the motor nerve cell (neuron) and the muscle cells it innervates is known as the motor unit.
          "The size of the motor units determines the precision of movement that a particular muscle can produce. For example, in the muscles of the larynx, or voice box, each motor nerve usually connects to only two or three individual muscle cells, allowing very fine gradations of strength. On the other hand, large muscles that serve gross movement--such as the gastrocnemius muscle in the lower leg--have motor units made up of motor nerves that each control 2,000 or more muscle cells.
          "These motor units are not all excited simultaneously when a muscle is electrically excited and made to contract. In fact, the units are excited in a most asynchronous fashion by the trains of electrical impulses that come down the motor nerves from the spinal cord. As a result, while some of the motor units are contracting and shortening within the muscle belly, others will be relaxing and lengthening. The tremendous amount of overlap between motor units gives the appearance that the muscle is contracting smoothly overall.
          "Strenuous exercise causes some of the motor units to drop out of service because of fatigue; it is this process that is ultimately responsible for the trembling you observe. Most of the fatigue probably occurs within the spinal cord at the level of the motor nerve cell and its neural connections, although some fatigue probably occurs also at the connections between this motor nerve and its muscle cells (the myoneural junction). Both these areas require the synthesis and release of particular chemicals to carry the electrical impulse across to either another nerve cell or a muscle cell. Researchers generally believe that the chemical cannot be manufactured and released fast enough to keep up with the level of activity, so it becomes depleted in this area of transmission. The depletion of these chemicals is a big part of what fatigue means in a biochemical sense.
          "As more and more motor units become temporarily nonfunctional, the muscle contraction becomes dependent on fewer and fewer motor units. The dropout of the fatigued motor units causes the remaining individual contractions and relaxations to become on average more synchronous and less smoothly organized; the original overall appearance of a smooth contraction is replaced with a jerky, trembling movement now that many of the overlapping motor units have ceased to function. After adequate rest, the fatigued motor units return to normal, and the muscle again appears to produce a smooth contractile motion.

          "Permanence, perseverance and persistence in spite of all obstacles, discouragement, and impossibilities: It is this, that in all things distinguishes the strong soul from the weak."

              Heb het trouwens ook vaak na een goede training..

              het maakt mij niet uit trouwens, hoort erbij... en trouwens als ik daarna een bakkie ga doen bij me opa en oma in het 55+ centrum val ik toch niet op.
