Conditions

People With Predominantly Sedentary Work

Brief summary

People who predominantly sit down often suffer from spinal complaints. This is mainly caused or intensified by a lack of exercise and a shortened posterior muscle chain. This study aims to investigate whether CrossFit can improve physical deficits, reduce pain, and improve quality of life. For this purpose, 30 test persons should take part in regular CrossFit training twice a week over one year. In addition, as a control group, 30 persons are also observed who exercise according to their ideas.
