The diaphragm is a sheet of internal skeletal muscle that performs an important function in respiration. When the diaphragm contracts the volume of the thoracic cavity increases and air is drawn into the lungs. Normal respiration is important, and can be affected by numerous factors such as age, environment, disease, an individuals lifestyle and even changes of posture.
Due to an increased use of electronic devices, which expose everyone to poor sitting and standing habits, there is an increased forward head lean. Slouched postural positions reduce the diaphragms tension and movement, lowering respiratory functions over time. The maintenance of correct head posture and strength is required to prevent functional reductions in this musculature, which will occur as we age.
Make sure head and neck training is inclusive in your fitness regime to live a healthy lifestyle.
