Yoga-Based Breathing Exercises in a Salt-Cave Environment Versus a Standard Clinical Setting in Smokers (SPELEO-SMOKERS)

Yoga-Based Breathing Exercises Performed in a Salt-Cave Environment Versus a Standard Clinical Setting in Smokers: A Randomized Controlled Trial
This randomized controlled trial evaluated whether performing the same yoga-based breathing exercise program in a salt-cave environment produced different respiratory, functional, physical activity, and quality-of-life outcomes compared with the same program performed in a standard clinical setting in adult smokers.
Sixty adult smokers were randomized to either a salt-cave group or a control group.
Both groups received a physiotherapist-supervised yoga-based breathing exercise program for 6 weeks, twice weekly, in 50-minute sessions.
The intervention content, frequency, duration, and physiotherapist supervision were identical in both groups; the only planned between-group difference was the intervention setting.
Spirometric outcomes were assessed at baseline, week 3, and week 6.
Functional exercise capacity, physical activity, and quality of life were assessed at baseline and week 6.

Descrizione dettagliata
Eligible participants were adult daily smokers aged 18 to 65 years who had smoked for at least the previous 12 months.
After baseline assessments, participants were randomized in a 1:1 ratio to the salt-cave group or the standard clinical setting group.
Allocation was generated by an independent researcher and concealed using sequentially numbered, opaque, sealed envelopes.
Both groups completed the same 6-week yoga-based breathing exercise program, delivered twice weekly under physiotherapist supervision.
Each standardized session lasted approximately 50 minutes and included preparatory breathing control, diaphragmatic breathing, Suusi breathing, Kapalabhati, Ujjayi, Anuloma-Viloma/Nadi Shodhana, Bhastrika, Bhramari, Agni Sar, and relaxation.
The salt-cave group received the program at the Tuzluca Salt Therapy Center, whereas the control group received the program in a standard private clinical setting.
Spirometric parameters included forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), and the FEV1/FVC ratio.
Secondary assessments included the 6-minute walk test, the International Physical Activity Questionnaire-Short Form, and the World Health Organization Quality of Life-BREF.
Participant and provider blinding was not feasible because the settings were visibly different.
Statistical analysis was conducted using coded group labels.

Sperimentale: Salt-Cave Yoga-Based Breathing Exercise Group
Participants completed the physiotherapist-supervised yoga-based breathing exercise program at the Tuzluca Salt Therapy Center for 6 weeks, twice weekly.
The program content, session duration, frequency, and supervision were identical to those of the comparator group; the planned between-group difference was the intervention setting.

Participants received a physiotherapist-supervised yoga-based breathing exercise program at the Tuzluca Salt Therapy Center.
The intervention lasted 6 weeks and included two sessions per week, for a total of 12 sessions.
Each standardized session lasted approximately 50 minutes and included preparatory breathing control, diaphragmatic breathing, Suusi breathing, Kapalabhati, Ujjayi, Anuloma-Viloma/Nadi Shodhana, Bhastrika, Bhramari, Agni Sar, and relaxation.
The exercise content, session frequency, duration, and physiotherapist supervision were identical to those provided in the standard clinical setting group; the planned difference was the intervention setting.

|
Change in Forced Expiratory Volume in 1 Second (FEV1) From Baseline to Week 6
Lasso di tempo: Baseline, week 3, and week 6; primary endpoint at week 6
|
FEV1 was measured in liters using pre-bronchodilator spirometry.
Participants performed three forced expiratory maneuvers under standardized instruction, and the best acceptable value was recorded.
The primary comparison was the between-group difference in change from baseline to week 6.
An interim measurement was also obtained at week 3
