Brief Summary

This study evaluates endurance of trunk muscles, balance and pulmonary functions in dancers. The participants will be evaluated trunk muscles endurance, pulmonary functions and balance which evaluated by computerized force plate system.

Detailed Description

Dance is a form of exercise associated with movements that require balance, flexibility, endurance and skill. In addition to maintaining balance, the endurance of the trunk stabilizer muscles has an important role in sport-specific activities, coordination and athletic performance. Studies which conducted on dancers are mainly focused on abdominal muscle strength / endurance, lower extremity strength and physical performance. In the literature, it was reported that 40-84% of professional dancers and 26-51% of professional dancers had musculoskeletal injuries, particularly lower extremity problems. It is very important to regain balance after returning to the dance after foot and ankle injuries. Considering the function of the trunk as a bridge between the lower and upper extremities, it is known that trunk muscles play a fundamental role in regaining balance. However, in the literature, there is no study showing the effects of trunk stabilizer muscles (abdominal, dorsal extensor, lateral flexor and diaphragm), trunk flexibility and dance-specific properties on balance in dancers. As a result of this study, it is aimed to show the effect of dance on balance and related parameters and to reveal the factors affecting the balance.

Arm && Interventions

Group	Intervention	Description
Experimental Group: Balance analysis	Balance analysis	fifty dancers will be evaluated in this study.Trunk muscle endurance, pulmonary functions and balance will be assessed.
Control Group:Balance Analysis	Balance analysis	fifty healthy subjects will be evaluated in this study.Trunk muscle endurance, pulmonary functions and balance will be assessed.

Primary Outcome Measures

Name	Time	Method
Limits of Stability	10 minutes	Limits of stability test evaluates dynamic balance of participants. Computerized balance system measured limits of stability for forward, backward, right and left side movements. It calculates the maximum distance a person can lean without losing balance. The unit of measure is centimeters. The higher value is indicated the better balance
Postural sway	10 minutes	Postural sway in centimeters by computerized balance system

Secondary Outcome Measures

Name	Time	Method
Maximal Inspiratory Pressure	15 minutes	It is a measure of the strength of inspiratory muscles, primarily the diaphragm. It is obtained by having the patient inhale as strongly as possible against a mouthpiece. After three trial, the best value is the outcome.
Forced Expiratory Volume in 1 Second	15 minutes	Forced Expiratory Volume in 1 Second is the volume exhaled during the first second of a forced expiratory maneuver started from the level of total lung capacity. After three trial, the best FVC value is the outcome.
Forced Expiratory Volume in 1 Second / Forced Vital Capacity	15 minutes	The ratio of Forced Expiratory Volume in 1 Second / Forced Vital Capacity. This formule is calculated by measuring device. After three trial, the best value is the outcome
Peak Expiratory Flow	15 minutes	Peak Expiratory Flow is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. After three trial, the best value is the outcome.
Trunk muscle endurance	15 minutes	The time to maintain the specified positions is recorded.
Maximal Expiratory Pressure	15 minutes	It is a measure of the strength of respiratory muscles, obtained by having the patient exhale as strongly as possible against a mouthpiece. After three trial, the best value is the outcome.
Forced Vital Capacity	15 minutes	It is the total amount of air exhaled during the test. After three trial, the best forced vital capacity value is the outcome
forced expiratory flow	15 minutes	Forced expiratory flow is the flow (or speed) of air coming out of the lung during the middle portion of a forced expiration.
Trunk flexibility	1 minutes	To measure flexibility, the participant will be instructed to push the yardstick placed at the edge of the box while holding the legs straight and the hands parallel to the floor as far as she could. this test in centimeters by measuring tape.
