WORKLOAD CONCEPT - Coggle Diagram

- - - - Seated Work
        
        The most comfortable working position is sitting. Within it, the most comfortable is the one that enables the trunk to remain straight and upright in front of the work surface and as close to it as possible
      - Foot work
        
        As a general rule, all work that involves a great muscular effort or displacement (handling of several machines, machines of large longitudinal dimensions, etc.) are carried out in a standing position
- - - - Make cargo handling easier
        
        modify the size and shape of the load so that the center of gravity is closer to the person lifting it;
        
         store the load at hip height so that the worker does not have to bend over;
        
         use mechanical means to lift the load at least to the hips;
      - Reduce the weight of the load
        
        repackage the cargo to decrease the size;
        
         decrease the number of objects carried at one time;
        
         assign more people to lift extraordinary heavy loads
    - - the weight of the load;
      -  how often the worker should lift the load;
      -  the distance of the load from the worker who must lift it;
      -  the shape of the load;
      -  the time needed to complete the task
    - - load pallets so that heavy items are around the edges of the pallet, not in the center
      - use shelves, shelves or loading platforms that are at an adequate height
    - - Heavy work should not exceed the capacity of each worker.
      -  Heavy physical work should alternate throughout the day, at regular intervals, with lighter work.
      -  Heavy physical work should alternate throughout the day, at regular intervals, with lighter work.
    - - redistribute the production or storage area
      - improve the layout of the work area;
    - - assign more people to that task;
      -  use mechanical instruments;
      -  rearrange the storage or work area
- - - - Dynamic muscular effort
        It occurs when there is a succession of contractions and relaxations of the active muscle (s) of very short duration (eg: walking, operating a crank, loading movement, etc.). This effort always produces movement or displacement
      - Static muscular effort It occurs when the contraction of the muscle is continuous and is maintained for a certain period of time
    - - Muscle tissue is made up of muscle fibers that, by presenting the property of contracting by the action of nervous stimuli, shorten their length
        
        When the muscle produces a dynamic effort, the succession of contractions and relaxation acts as a pump on the blood circulation that accelerates. The muscle is well watered, oxygen and glucose are supplied regularly to the muscle, and the waste is gradually evacuated
