Brief Summary

Dance is a performing art form consisting of sports and art intertwined and complex dynamic choreographic figures were handled aesthetically and physically of narrative. Scientific studies are insufficient on dance and health and performance of dancers in the literature although dance is the most used type of art and sport in all societies and for all age groups. It is seen that the core stabilization (central forces) of the dancers is insufficient when the current studies were examined, this insufficient stabilization causes biomechanical changes in the trunk, and indirectly affects the lower extremities. Consequently, insufficient stabilization was shown to be caused impairment of force generation and injuries. In addition, lack of core stabilization of dancers may cause impairment in balance and postural control. Therefore, dancers need a good postural control with provided by an effective core stabilization training in order to exhibit a successful and healthy performance. It is shown that inspiratory muscle training (IMT) improves diaphragm strength and diaphragm thickness. Considering the relation between diaphragm muscle forming the upper (ceiling) part of the core area, and balance, IMT may also have an impact on postural control and balance alongside the standard clinical parameters such as respiratory muscle strength and diaphragm thickness in dancers. Thus, the aim of this study was to investigate the effects of inspiratory muscle training on diaphragm thickness, postural stability, balance, respiratory muscle strength in dancers.

Study Groups

Training Group

Dancers in this group will perform inspiratory muscle training for 30 breaths, twice daily \[morning: between 7:00 and 13:00 and evening: between 16:00 and 22:00\], 7 days per week for 8 weeks, with a breathing frequency of 15 breaths per minute and a duty cycle of 0.5. One exercise session will be supervised in a clinic per week, other sessions will be performed at home in every week during the training.

Group Type: EXPERIMENTAL

Inspiratory muscle training(high-IMT group)

Intervention Type: OTHER

A mechanical pressure threshold loading device (POWERbreathe, POWERbreathe International Ltd, UK) will be used for the training. Training intensity will set at 60% of the maximum inspiratory pressure.

Sham Group

Dancers in this group will perform inspiratory muscle training for 30 breaths, twice daily \[morning: between 7:00 and 13:00 and evening: between 16:00 and 22:00\], 7 days per week for 8 weeks, with a breathing frequency of 15 breaths per minute and a duty cycle of 0.5. One exercise session will be supervised in a clinic per week, other sessions will be performed at home in every week during the training.

Group Type: SHAM_COMPARATOR

Inspiratory muscle training(low-IMT group)

Intervention Type: OTHER

Dancers will be perform at a load setting of level 1 (corresponding to \~10% baseline MIP), using the same device as the training group.

Interventions

A mechanical pressure threshold loading device (POWERbreathe, POWERbreathe International Ltd, UK) will be used for the training. Training intensity will set at 60% of the maximum inspiratory pressure.

Intervention Type: OTHER

Inspiratory muscle training(low-IMT group)

Dancers will be perform at a load setting of level 1 (corresponding to \~10% baseline MIP), using the same device as the training group.
