Clinical Trial Summary

An observational cohort study, following the Strengthening the Reporting of Observational Studies in Epidemiology(STROBE) guidelines.

Two groups will be examined, a group composed by spanish acrobatic skydivers and a control group composed by general physically active population(GPAP).

Description:

Two groups will be examined for veryfing the morfology and the function of neck muscles.

The profesional group composed by spanish acrobatic skydivers and a general group composed by general physically active population(GPAP). Both groups are matched at known confounder outcomes such as: physical activity level, age, sex, body weight and history of neck pain. Frequency matching will be carried out, subjects will be matched on known confounders.
