Everyone has his beliefs and I won't change yours and you won't change mine. That's a bad situation but we can't change it.

A continuous maximal contraction is needed when lifting something very heavy, like a piano. Everyone will be aware of how rapidly fatigue can set in during such activities. In this situation the muscle machinery is going at full speed and energy is consumed at a rapid rate. In addition, the blood flow to the active muscle(s) is stopped during maximal contractions so that no delivery of oxygen (to support muscle contraction) or removal of metabolites or ions will occur. Thus severe fatigue develops within seconds and the muscle becomes rapidly weaker. Changes of the ionic distribution over the cell membrane probably contribute to this type of fatigue. Each action potential is associated with entry of sodium ions into the cell and exit of potassium ions from the cell; consequently potassium ions tend to accumulate outside of the fibres and this results in depolarization and impaired electrical activation of muscle cells. This extracellular accumulation of potassium is likely to be larger in the narrow lumen of the t-tubules from which the potassium ions can only diffuse rather slowly. This leads to impaired propagation of action potentials into the deep parts of fibres and, as a consequence,reduced Ca2+ levels and contractile activation in the central core of fibres.

Workout n°7
Deadlift : 146.25
Curl L/R : 26
Floor L/R : 41
Everything was realtively easy despite an huge fatigue/stress (due to work). This week end the loads should feel lighter.
