Effects of a Structured Multicomponent Physical Exercise Intervention on Quality of Life and Biopsychosocial Health among Chilean Older Adults from the Community with Controlled Multimorbidity: A Pre–Post Design

Abstract

Structured multicomponent physical exercise (PE) for older adults, with a combination of strength, aerobic, flexibility, and balance exercises, has been shown to have benefits for physical, cognitive, social, and metabolic functioning, as well as counteracting chronic pathologies and geriatric syndromes. However, little is known about the effect of these interventions in Chilean older adults. Our objective was to determine the effect of a structured multicomponent PE intervention on the quality of life (QoL) and biopsychosocial factors of community-living older adults. We conducted a pre–post intervention without control group, with a face-to-face structured multicomponent PE intervention (cardiovascular, strength/power, flexibility, static and dynamic balance, other psychomotor components, and education), based on FITT-VP principles (frequency, intensity, type, time, volume, and progression of exercise), at moderate intensity, 60 min per session, three times per week, and 12 weeks in duration, among 45 persons with an average age of 70.74 years. Participants were evaluated at the beginning and end of the intervention with different instruments of comprehensive gerontological assessment (CGA). Post intervention, participants (83.70% average attendance) significantly improved scores in QoL, biological and biopsychosocial frailty, sarcopenia, functionality in basic, instrumental, and advanced activities of daily living, dynamic balance, cognitive status and mood, systolic and diastolic blood pressure, weight, body mass index, strength and flexibility clinical tests of lower and upper extremity, aerobic capacity, agility, and tandem balance. The indication and prescription of structured multicomponent PE based on FITT-VP principles, as evaluated with the CGA, improved the QoL and biopsychosocial health of older adults. This intervention could serve as a pilot for RCTs or to improve PE programs or services for older adults under the auspices of existing public policy.

Measuring Quality of Life: Incorporating Objectively Measurable Parameters within the Cross-Sectional Bern Cohort Study 2014 (BeCS-14)

“…From a young age to about 75 years old, body weight and, consequently, BMI usually increase [40]. Psychomotor endurance, as part of the tapping test for checking the basic psychomotor speed and functional maturity, characterizes psychomotor behavior and agility [39,41]. The influence of psychomotor activity on quality of life has already been proven.…”

Rehabilitation of Older Adults With Multimorbidities

“…Dynapenia is characterized by a decrease in muscle strength without a reduction in muscle bulk. Elderly persons with dynapenia are more likely to have functional limitations and death [34]. In this context, protocols targeting muscle strength and function may provide further benefits in reducing the risk of multimorbidity.…”

Social Outbreak in Chile, and Its Association with the Effects Biological, Psychological, Social, and Quality of Life

“…The second item featured 3 questions aimed at assessing the effects of the social outbreak on the bio-psycho-social spheres, grouping a total of 35 bio-psycho-social symptoms (Yes/No). When it comes to assessing biological, psychological, and social symptoms, we have drawn upon the framework of comprehensive gerontological assessment as a reference point to identify these major aspects of individuals' health [40]. Furthermore, we've taken into account a set of questions that serve as the initial basis for designing and identifying the symptoms used in this research.…”
