Exercise interventions have small clinical benefits on  PA  levels in community-dwelling older adults , with a decline in the observed improvement after six months of the intervention cessation
Exercise is a form of physical activity ( PA ) .
PA is an important marker of health and quality of life in older adults .
The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure , and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65 + year-old adults .
Assessing the Effects of Interpersonal and Intrapersonal Behavior Change Strategies on Physical Activity in Older Adults: a Factorial Experiment
Abstract Background Little is known about which behavior change strategies motivate older adults to increase their physical activity . Purpose The purpose of this study was to assess the relative effects of two sets of behavior change strategies to motivate increased physical activity among older adults :  interpersonal and intrapersonal . Methods Community-dwelling older adults ( N = 102 , mean age = 79 ) were r and omized in a 2 × 2 factorial experiment to receive interpersonal ( e.g. , social support , friendly social comparison ; no , yes ) and /or intrapersonal ( e.g. , goal setting , barriers management ; no , yes ) behavior change strategies , combined with an evidence -based , physical activity protocol ( Otago exercise program ) and a physical activity monitor ( Fitbit One ™ ) . Results Based on monitor data , participants who received interpersonal strategies , compared to those who did not , increased their average minutes of total physical activity ( light , moderate , vigorous ) per week , immediately ( p = .006 ) and 6 months ( p = .048 ) post-intervention . Similar , increases were observed on measures of functional strength and balance , immediately ( p = .012 ) and 6 months ( p = .003 ) post-intervention . The intrapersonal strategies did not elicit a significant increase in physical activity or functional strength and balance . Conclusions Findings suggest a set of interpersonally oriented behavior change strategies combined with an evidence -based physical activity protocol can elicit modest , but statistically and clinical ly significant , increases in older adults ’ physical activity and functional strength and balance . Future research should replicate these findings and investigate the sustained quantity of physical activity elicited by these strategies and their impact on older adults ’ quality of life and falls . Trial Registration The Clinical Trials.gov registration identifier is NCT02433249
