Assessment of usable and suitable tests for maximum physical power in workers

Background and aims: The physical and mental health of workers is very important in occupational health, one of the most important organs of the body is cardiovascular system or blood circulation. Various occupational factors affect it. Cardiovascular health in workers is an important item. Before doing physical work, such as exercise or work, it is necessary to determine the maximum aerobic capacity of individuals. However, this was not a matter for business for a few years ago, and it was only for professional athletes performing a series of aerobic tests before going to work professionally it was done. Today, the importance of this issue has been detected in physically active workers, but for some reason it is difficult to determine the maximum aerobic capacity of the workforce, but it can find a good place in physical examinations. Occupational physiology is contented cardiovascular system; heart and blood circulation and vessels such as arteries, veins and capillaries, respiratory system; lungs, musculoskeletal system and other related organs, but cardiovascular system has an important situation in this item. Heart beat, cardiac output, electrocardiogeraphy and its changes are main variables in tests and examination. Heart beat in many test has major importance; step and bike tests. Electrocardiography in treadmill tests is assessed. Changes of electrocardiography such as P wave, P-R, QRS complex, T wave, ST are assessed. Occupational physiology is one of the subject in ergonomic factors. Ergonimic factors are occupational physiology, anthropometry, environmental physiology, industrial psychology and biomechanic. Anthropometry is study on measurement of human body, it is used in making worker’s station. Environmental physiology is environmental factors such as temperature. Biomechanic is study on skeleton muscles and joints, working postures and lifting loads. Industrial psychology is study about stress in workplace and prevention of it. Occupational physiology was an important and must be assessed for many situation such as preplacement examination for workers, fitness for work or sport, periodic physical examination, return to physical work, impairment and disability assessment and calculation. Aim was determining the appropriate and suitable tests for determination the maximum aerobic power in working people in a review study, the objective of the study was determination the tests for calculation of the maximum aerobic power in workers according to jobs and ages. Methods: Using the scientific resources up to day, validated and scientific websites related to medical sciences was conducted on the tests used to determine the maximum physical aerobic power of review research. In this study, the tests were divided into four major categories. The results of job and age were compared. The first group of tests performed by the standard step, the second group of tests performed by an ergometer bike, the third group of tests performed by the treadmill and the fourth group of tests that were not required by the special instrument. Determine the research question, determine the instructions for doing the study, review the texts, evaluate the information in the studies, analyze the findings and interpret it, so that the researcher can determine the appropriate tests in each case. All studies on the determination of maximum aerobic power in employed people from 1970 to 2018, review of texts in scientific books, journals and related scientific sites, motor searching such as Springer, Pubmed, Scopus, Google scholar, Elzevier, Wiley, Web of science, Medline, magazines and books on Sport medicine and Occupational health ,physiology and Occupational medicine, Behdasht ministry, international labor organization, occupational safety and health administration, national institute for occupational health and safety websites. Based on the method of measuring maximum aerobic power, the name of the test and the type of job was
