A total of 114 adults between the ages of 50 and 80 yr. were recruited for a study of fitness. The participants were divided into Structured, Self-imposed, Social, and Nonexercise groups to reflect their levels of physical activity and then were compared on cognitive and physiological variables. Significant differences were noted for fear, assertiveness, depression, and percentage of body fat. Multiple discriminant analyses suggested that group membership could be predicted with 100% success for Structured exercisers compared to Social and Nonexercisers. However, predictability decreased when examining Structured and Self-imposed exercisers. One may infer that people who are more fearful, more assertive, and more depressed participated in exercise. Involvement in a 12-wk. exercise program significantly reduced depression and body-fat concentration.
共有114名年龄在50至80岁之间的成年人被招募来参与一项健康研究。参与者被分为结构化锻炼组、自主锻炼组、社交锻炼组和非锻炼组，以反映他们的身体活动水平，然后在认知和生理变量方面进行比较。在恐惧、自信、抑郁和体脂百分比方面发现了显著差异。多重判别分析表明，与社交锻炼组和非锻炼组相比，结构化锻炼者的组成组可以100%成功预测。然而，在检查结构化锻炼者和自主锻炼者时，可预测性降低。可以推断，更恐惧、更自信和更抑郁的人参与了锻炼。参与为期12周的锻炼计划显著降低了抑郁和体脂浓度。
