A healthy lifestyle and proper growth and development are extremely important for proper morphological formation and quality of life. Physical activity is of great importance for the entire population in order to preserve and improve overall health. Playing sports and recreation is the lifestyle of more and more people. However, as physical activity has various positive effects on health, on the other hand, there are also negative effects, primarily due to the number of injuries and damage to the movement system (cartilage, muscle, tendon or bone). Chronic damage caused in sports and recreation or in some professions is the result of long-term repeated microtraumas that cause overstrain of some tissues, that is, part of the movement system. In most cases, the person has not felt or does not remember the time of damage until the inflammatory process and pain appear, which then limit the continuation of activities or impair the quality of life. The aim of this work is to explain why and how postural disorders and anatomical deviations can affect these injuries and damages. To begin with, it is important to understand what postural alignment means and the simplest way to get a posture analysis, according to which possible potential injuries can be predicted. Therefore, it is important to understand why overexertion syndrome occurs and to know how to diagnose and treat overexertion syndrome in time, that is, how to prevent the onset of the syndrome.
