Objectives: Weight gain and obesity-related diseases are associated with the postmenopausal period. Moderate intensity exercise may be protective through attenuation of weight gain, however, many postmenopausal women do not engage in regular exercise. This study investigated the exercise behaviour of postmenopausal women in regional Queensland to determine whether differences existed for personal, physiological and psychological variables and if so, which of these variables may predict future exercise behaviour.

Methods: Participants were postmenopausal women (N=101) resident in North Queensland. A self-report questionnaire, the Self-efficacy for Exercise Scale and the Health Belief Model Scale were completed. Anthropometric and physiological measures were obtained. Participants also completed a 20 minute moderate intensity exercise bout on a cycle ergometer; measures of affect were obtained using the Subjective Exercise Experience Scale. Participants were then categorised as exercisers (n=53) or non-exercisers (n=48).

Results: Compared to the exercisers, the non-exercisers had a lower level of education (U = 971.5, p = 0.03), cardio respiratory fitness (F1,99=21.57, p=0.00) and exercise self-efficacy (F1,99=39.56, p=0.00) and higher resting diastolic blood pressure (F1,99=7.57, p=0.01) and BMI (F1,99=33.63, p=0.00).

The barrier items of perceived lack of time, difficulty getting to an exercise location and the weather provided the greatest discrimination between exercisers and non-exercisers. However, the acute exercise bout produced higher positive well-being postexercise compared to pre and during exercise for both groups.

Conclusions: Identification of the differences in exercise behaviour between exercisers and non-exercisers may provide information for future health promotion policy directions for this population and allow for the formulation of guidelines for exercise professionals.
