People With Predominantly Sedentary WorkNCT05109286
A Controlled Trial to Evaluate the Benefits of CrossFit in People Who Work Predominantly in a Sedentary Manner.
A study testing CrossFit in people with People With Predominantly Sedentary Work, run by Bundeswehr University Munich at 1 site in Germany.
Trial 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. Read more about this study

About this study
Official title: MedXFit Intervention for Predominantly Seated People
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mobility
Changes in the Functional Movement Screen (FMS) according to Cook G. et al.; Int J Sports Phys Ther, 2014. FMS has a range from 0 -21 (0 = worst, 21 = best).
Measured: 1 year
Secondary outcomes (3)
Strength Symmetry
Strength was assessed in kg using the Dr. WOLFF BackCheck® 617 (BC). The BC allows to measure maximum isometric strength. Furthermore, it provides reference data to evaluate strength and strength symmetry values on a scale ranging from 0 - 10 (0 = worst, 10 = best)
Measured: 1 year
Strength
Strength was assessed in kg using the Dr. WOLFF BackCheck® 617 (BC).
Measured: 1 year
Subjective Well-Being
Subjective Well-Being was measured with the World Health Organization Well-Being Index (WHO-5). WHO-5 has a range from 0 -25 (0 = worst, 25 = best).
Measured: 1 year
