The present study documents the maintenance of exercise participation, self-efficacy, and physiological change in older adults at 9-month follow-up to a 5-month structured exercise program. Males and females (mean age = 54 years) completed graded exercise testing, body composition, and physical performance testing at the end of and 9 months after cessation of an exercise program. Self-efficacy assessments were also conducted prior to and following each graded exercise test and in the last week of the program. Results indicated that whereas some general reductions in physiological conditioning occurred, significant declines in physical performance and self-efficacy measures were evidenced at follow-up. However, exposure to the acute bout of physical testing increased the efficacy expectations to the point were they were no longer significantly different from postexercise program levels. Moreover, exercise self-efficacy was the only variable to significantly predict adherence to exercise during follow-up. However, previous attendance in the program, aerobic capacity, and self-efficacy all significantly discriminated between compliers and noncompliers to exercise prescription. Results are discussed with respect to the role played by acute exercise bouts in enhancing perceptions of personal efficacy in older adults and the utility of self-efficacy as a predictor of exercise behavior at various stages of the exercise process.
本研究记录了老年人在参加为期5个月的结构化锻炼计划后的9个月随访中,其锻炼参与度、自我效能感和生理变化的维持情况。男性和女性(平均年龄 = 54岁)在锻炼计划结束时以及停止锻炼9个月后完成了分级运动测试、身体成分和身体机能测试。在每次分级运动测试之前和之后以及计划的最后一周也进行了自我效能评估。结果表明,虽然生理机能总体上有所下降,但在随访中身体机能和自我效能指标出现了显著下降。然而,进行急性身体测试提高了效能期望,使其与锻炼计划后的水平不再有显著差异。此外,锻炼自我效能是唯一能显著预测随访期间锻炼依从性的变量。然而,之前参与该计划的情况、有氧能力和自我效能在遵守与不遵守锻炼处方的人群之间均有显著差异。本文将结合急性运动对增强老年人个人效能感认知所起的作用以及自我效能作为锻炼行为在锻炼过程各个阶段预测指标的效用,对研究结果进行讨论。
