Perceptions of the behavioral influence of goals: A mediational relationship to exercise

Abstract

In the present study, it is argued that a more fundamental approach is necessary for the study of exercise goals and exercise behavior if we are to understand their relationship. The specific purposes of the investigation were to a) examine the relationships between perceptions of the behavioral influence of goals, moderators of goal influence (i.e., goal clarity) and perceptions of required exercise behavior (frequency and intensity), (b) examine changes that occurred over time to measures of goal-related variables and (c) describe various personal exercise goals and related action plans to achieve goals. Ninety-nine healthy adults in intermediate level university fitness classes were volunteers in this prospective study. The present study revealed that exercisers have multiple goals and action plans and are also knowledgeable about the specific behavioral strategies and exercise behaviors required to attain these goals. Also, the clarity, commitment, and perceived behavioral influence of goals increased as adherers gained experience with the exercise program. Finally, perceptions of the way goals influence behavior was found to mediate the goal clarity-exercise intensity and the goal commitment-exercise intensity relationships at the beginning of the exercise program but not at mid-program. Instead, independent relationships emerged at midprogram between goal clarity and goal influence, goal commitment and goal influence, goal clarity and exercise intensity, goal commitment and exercise intensity, and goal influence and exercise intensity. Results an discussed in terms of the complex and changing nature of the perceptions people hold of their goals and how these goals influence their exercise.     

Older adults with chronic disease: benefits of group-mediated counseling in the promotion of physically active lifestyles.

In this 12-month trial standard exercise training was compared with a group-mediated cognitive-behavioral (GMCB) intervention with respect to effects on long-term adherence and change in physical function of older adults who were either at risk for or had cardiovascular disease. Participants (147 older men and women) were randomized to the 2 treatments. Outcomes included self-reportedphysical activity, fitness, and self-efficacy. The GMCB treatment produced greater improvements on all outcomes than did standard exercise therapy. Regardless of treatment assignment, men had more favorable change on the study outcomes than did women. Analysis of a self-regulatory process measure in the GMCB group revealed that change in barriers efficacy was related to change in physical activity and fitness. Results suggest that teaching older adults to integrate physical activity into their lives via GMCB leads to better long-term outcomes than standardized exercise therapy.
