Brief summary

The goal of this randomized-controlled study is to compare the effects of diaphragmatic breathing exercise training provided by a physiotherapist and aerobic exercise training applied in addition to diaphragmatic breathing exercise training provided by a physiotherapist on respiratory functions and voice performance in choir singers. The main questions this study aims to answer are: * Is diaphragmatic breathing exercise training provided by a physiotherapist effective in improving the respiratory functions of choir singers? * Is diaphragmatic breathing exercise training provided by a physiotherapist effective in improving the vocal performance of choir singers? * Does aerobic exercise training applied in addition to diaphragmatic breathing exercise training provided by a physiotherapist have a greater effect on improving the respiratory functions of choir singers compared to diaphragmatic breathing exercise training applied alone? * Does aerobic exercise training applied in addition to diaphragmatic breathing exercise training provided by a physiotherapist have a greater effect on improving the vocal performance of choir singers compared to diaphragmatic breathing exercise training applied alone? The research data are going to be collected by Sociodemographic Information Form, International Physical Activity Questionnaire-Short Form, Self-Performance Evaluation Questionnaire, Vocal Fatigue Index, Singing Voice Handicap Index, measurement of maximum phonation time, pulmonary function test, maximal inspiratory and expiratory pressure measurement, and 6-minute walk test.

Detailed description

In this study, it will be examined whether aerobic exercise training applied in addition to diaphragmatic breathing exercise training provided by a physiotherapist improves respiratory functions and voice performance in choir singers more, when compared to diaphragmatic breathing exercise training applied alone. The participants will be randomly divided into three groups: diaphragmatic breathing exercise training group, aerobic exercise training group applied in addition to diaphragmatic breathing exercise training, and control group.

Interventions

BEHAVIORALDiaphragmatic breathing exercise training

At the end of the training, participants will be asked to do an exercise session and this session will be observed. Training will continue until participants learn and apply the exercise correctly. 5-minute warm-up and cool-down periods will be applied at the beginning and end of each exercise session. Exercises will be done twice a day, morning and evening, for 8 weeks. In order to follow the exercise, participants will be given diaphragmatic breathing exercise tracking cards with date and session information. In addition, participants will be followed up weekly on one of the rehearsal days to ensure their adaptation to the exercise.

BEHAVIORALAerobic exercise training

The intensity of the aerobic exercise program will be calculated for each participant using the Karvonen formula. Accordingly, each participant will be given a brisk walking program on a suitable surface, which will be created specifically for the individual to reach the target heart rate range within the scope of the aerobic exercise program; they will apply a 45-minute session, 3 days a week, for 8 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Maximum phonation timeThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Each participant will be asked to say the vowels a, e, i, o, u at their most comfortable pitch for as long as possible, and the time they can say them will be determined by a stopwatch.
FEV1/FVCThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Pulmonary function test with a spirometer will be performed on all participants to assess forced expiratory volume in 1 second and forced vital capacity.
Slow vital capacityThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Pulmonary function test with a spirometer will be performed on all participants to assess slow vital capacity.
Maximal voluntary ventilationThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Pulmonary function test with a spirometer will be performed on all participants to assess maximal voluntary ventilation.
Maximal inspiratory and expiratory pressureThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.An electronic respiratory pressure meter will be used to calculate maximal inspiratory and expiratory pressure

Secondary

MeasureTime frameDescription
Vocal fatigueThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Vocal Fatigue Index which is a self-report questionnaire for identifying individuals with vocal fatigue and characterizing their complaints will be used to assess the vocal fatigue of all participants.
Singing voice and voice-related problemsThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.Singing Voice Handicap Index will be used to assess the voice-related handicaps of all participants.
Voice performanceThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.The Self-Performance Evaluation Questionnaire, which is created by the researcher and is a scale in which the participant evaluates his/her own musical performance by scoring it between from 1 to 10, will be used to evaluate the performance.
Aerobic capacity and enduranceThis outcome will be evaluated twice: before starting the exercise program and after implementing the exercise program for 8 weeks.6 Minute Walk Test will be performed on all participants to assess aerobic capacity and endurance.
