- - - - Anthropometry
        
        It deals with measurements of the human body that refer to body size, shape, strength, and work capacity.
        
        Functional anthropometry; also called dynamic anthropometry, which studies the composite measurements of a human being in motion, for example: stretching
        
        Structural anthropometry; or static, which refers to the simple dimensions of a human being at rest, for example: weight, height
      - Biomechanics and Physiology
        
        It is dedicated to the study of the human body from classical or Newtonian mechanics, and biology. Its objective is the study of the body in order to obtain maximum performance
      - Environmental ergonomics
        
        Physical conditions that surround the human being and that influence their performance when carrying out various activities, such as the thermal environment, noise level, lighting level and vibrations
      - Preventive and Corrective Ergonomics.
        
        works with the disciplines in charge of safety and hygiene in the work areas. Its activities include the study and analysis of safety, health and work comfort conditions.
      - Cognitive Ergonomics
        
        They deal with topics such as the process of receiving signals and information, the ability to process it and act based on the information obtained, knowledge and previous experience.
      - Needs Ergonomics
        
        It is mainly focused on the design and development of equipment for people with physical disabilities, for children and school population
      - Design and Evaluation Ergonomics
        
        His contribution uses concepts and data obtained from anthropometric measurements, biomechanical evaluations, sociological characteristics and customs of the population to which the design is directed.
- - - - It occurs when muscle contraction is continuous and is sustained for a certain period of time
    - - It occurs when there is a succession of contractions and relaxations of the active muscle or muscles of very short duration
    - - It involves an overload of the muscles of the legs, back and shoulders, therefore, alternating with other postures, thus reducing the postural physical load.
    - - It is the task of less static load on the postural muscles. But a bad design between the seat and the table or work plane, can increase the static load on certain muscle groups
    - - Manual work must be properly designed so that workers do not exhaust or contract muscle tension, especially in the back.
