To investigate what are the effects of pre-surgical aerobic dance-based exercise programme (PSADBE) and physical activity counselling (PAC) programme on lower extremity functions after surgery in people with morbid obesity awaiting bariatric surgery (PMOABS). This study was a single-blind, randomized controlled study. Groups were divided into Group I (PSADBE and PAC) and Group II (PAC). Both groups received PAC, Group I completed the PSADBE programme accompanied by music for 60 min/2 days/8 weeks. Thirty-four PMOABS were included in the study. The 6-Minute Walking Test, as primary outcomes, and The Stair Climbing Up-Down Test for evaluating functional capacity, Biodex Isokinetic Test and Exercise System® for evaluating muscle strength were used. Besides, muscle endurance, physical activity (PA) level, fatigue and quality of life (QoL) were also assessed. All measurements were repeated three times; pre-treatment, post-treatment and the fifth-month post-surgery. After 8 weeks, significant changes were found in functional capacity, muscle strength and endurance, PA level, fatigue and QoL in both groups (p < .05). Comparing the groups, the changes in functional capacity, muscle strength and endurance, PA and fatigue scores after treatment and the fifth-month post-surgery were statistically superior in Group I (p < .05). Adding an 8-week PSADBE programme to PAC is an effective treatment option for improving postoperative functional capacity, muscle strength and endurance, PA level and fatigue in PMOABS.
