Study Details

Study Description

Brief 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).

Condition or Disease	Intervention/Treatment	Phase
Neck Muscle Issue Sternocleidomastoid; Contracture Deltoid Muscle Strain	Behavioral: Observation

Detailed 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.

Outcome Measures

Primary Outcome Measures

Anticipatory postural adjustment [10 minutes]
Electromyographic test in ms.The myoelectric signal will be recorded by using mDurance R system (mDurance Solutions SL, Granada). The electrodes used will be pre-gelled Ag/AgCl with a diameter of 10mm and an interelectrode distance of 20mm.
Isometric cervical strength [10 minutes]
Measured in newton with heandheld Dynamometer (model 001165, Lafayette Instrument Company)
Neck flexor and extensor endurance [10 minutes]
Measures in seconds with a stopwatch
