Effects of pre‐surgical aerobic dance‐based exercise on lower extremity in people with morbid obesity awaiting bariatric surgery: Randomized controlled study

Abstract

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 fifthmonth 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 postsurgery 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.

Effects of bariatric surgery on muscle strength and quality: A systematic review and meta‐analysis

“…Answers were obtained in 53% of the cases. 20,21,45,[50][51][52][54][55][56][57][58] Most of the selected studies performed short-term post-surgical evaluations (i.e., between one and 12 months after BS), except for three publications that followed participants up to 2, 56 5, 46 and 9 years 59 post-surgery. Therefore, analyses of the changes in muscle strength/MQ in the medium or long term 60 were not possible as there were insufficient studies.…”

“…67,73 Only one study reported an increase in absolute dynamic strength 12 months after BS in upper and lower limbs. 21 On the other hand, the absolute isokinetic dynamic strength of the lower limbs showed a decrease, 61 no changes, 58 or a 30% reduction after surgery but without reporting a p value. 71 (Table 3).…”

“…The studies covered various BS techniques: Roux-en-Y gastric bypass (RYGB; 14 studies 20,21,42,44,49,50,52,54,56,59,69,70,73,74 ) and sleeve gastrectomy (SG; seven studies 45,47,53,58,63,64,67 ), the most frequently used. Besides, eight studies presented results covering either RYGB or SG, 19,43,55,61,62,68,72,75 while the remainder used other surgical techniques or a combination of them.…”

“…On the other hand, six studies assessed lower-limb functional capacity through the sit-to-stand test (five times sit-to-stand test or number of repetitions in 30 s), 50,56,58,65,69,73 showing a significant improvement after surgery in four of them. 56,58,65,69 Three additional studies also used the sit-to-stand test but not reported any p value for change. 20,55,71…”

The Effect of Aerobic and Resistance Exercise after Bariatric Surgery: A Systematic Review

“…During the assessment sessions, a six-minute walk test, a Stair Climbing Up-Down Test, an Isokinetic Test, PA level measurements, fatigue measurements, and QoL measurements were conducted. Statistically significant improvements were observed in functional capacity, muscle strength and endurance, physical activity (PA), and fatigue scores after treatment and in the fifth month post-surgery in Group I (p < 0.05) [28].…”
