Modern lifestyle opposes the natural design of the human body, which is adapted to movement. The average person spends more than 8 hours a day in a sitting position, which is not natural and is responsible for many diseases and painful conditions. During all these hours of sitting, the spine usually begins to bend forward, which most often entails protraction of the head and rounded shoulders. The hip flexors adapt to a bent position and consequently pull the pelvis into an anterior tilt, while on the other hand, the hip extensors literally shut down. The body adapts to the position in which we spend most of the day. When we train it to adapt more to sitting than moving, these adaptations are transferred to all aspects of life, not just sitting. It affects the way we move the rest of the day, limits us in performing daily activities and leads to the development of painful conditions. Lumbar pain syndrome, carpal tunnel syndrome, neck pain, shoulder pain, hip pain, and tennis elbow are just some of the examples. The aim of this work is to show the impact of prolonged sitting on posture and quality of life and to explain the role of kinesitherapy in the prevention and treatment of its consequences.
