PSYCHOLOGICAL AND PHYSIOLOGICAL EFFECTS OF A FOUR-MONTH EXERCISE PROGRAM ON TYPE 2 DIABETICS
Abstract
The purpose of this study was to determine the alterations in the physiological, biochemical, and psychological functions of type 2 diabetics following a moderate physical exercise program. Nineteen type 2 diabetics were randomly assigned to either the exercise (n = 11, 3 males), or the control (n = 8, 3 males) groups. Data were collected at the beginning and at the conclusion of a four-month period. In addition to anthropometric data, resting heart rate and blood pressure, recovery heart rate and blood pressure, submaximal heart rate and oxygen uptake, near-maximal heart rate and oxygen uptake, and a physical fitness score were obtained. The biochemical variables were obtained after an overnight fast, and consisted of serum cholesterol, serum triglycerides, serum glucose, plasma insulin, plasma glycosylated hemoglobin, and plasma high density lipoprotein. The psychological data were obtained from the self-administered Clinical Analysis Questionnaire (CAQ). The data were analyzed using univariate and multivariate procedures. Within the limitations of the study, the following conclusions were drawn: (1) The univariate results showed that a four-month physical exercise program has minimal effect on the physiological, biochemical and psychological measurements of type 2 diabetics. (2) The factor analysis results support the notion that physical exercise is related not only to the physiologic and metabolic characteristics, but also to the psychologic aspects of type 2 diabetics. (3) The discriminant function analysis showed that the psychological domain was a more powerful discriminator between the exercise and control groups than either the physiological or biochemical domains.
