Effect of Chair Suryanamaskar with Strength Training on Functional Fitness in Frail Older Adults: A Research Protocol for a Randomised Controlled Trial

Abstract

Introduction: Physical frailty is a syndrome characterised by deterioration in multiple physiological domains, including muscle mass and strength, flexibility, balance, neuromuscular coordination, and cardiovascular function. Evidence suggests that regular exercise provides substantial health benefits, reducing the risk of many chronic diseases and medical costs, especially for frail older adults. However, the effect of exercise on functional status in this population is not well explored. Need of the study: Population aging in India is rapidly accelerating, and frailty is a significant clinical condition associated with aging. Frailty increases the risk of institutionalisation, morbidity, and mortality. Regular exercise has been shown to improve functional fitness in older adults, but exercises performed while standing unaided can be challenging for individuals with compromised balance and mobility. Chair Suryanamaskar, a form of exercise performed while seated, may be an alternative mode of exercise for this population. Although aerobic and resistance exercises have shown benefits, there is growing interest in exploring the potential benefits of a multicomponent intervention for frail older adults. Aim: The aim of this study is to investigate the effect of chair Suryanamaskar with strength training on functional fitness in community-dwelling frail older adults. Materials and Methods: The study will be conducted from March 2021 to March 2024. This two-group parallel singleblind randomised controlled trial will take place at MAEER's Physiotherapy College in TalegaonDabhade, Maharashtra, India. Approximately 400 older adults will be screened for frailty using the Short Physical Performance Battery (SPPB) test. Participants with an SPPB score ≤7 will be considered frail and a total of 108 participants aged 65-84 years will be recruited based on inclusion and exclusion criteria. The participants will be equally divided into two groups (54 participants in each group) using computer-generated random tables. The experimental group (group A) will receive a 45-minute Chair Suryanamaskar with strength training protocol three times a week for 12 weeks. Before the study begins, participants will have two practice sessions of 20 minutes each to become familiar with Chair Suryanamaskar. The control group (group B) will participate in two 20-minute health education program sessions and receive weekly telephonic follow-ups to monitor for adverse events. Additionally, a health education program booklet will be provided. The primary outcome of the study is the Senior Fitness Test (SFT). Assessments will be conducted at baseline (0 weeks) and post-intervention (12 weeks). Intentionto-treat analyses with mixed linear modeling will be used for statistical analysis.
