Correlates of exercise motivation and behavior in a population-based sample of endometrial cancer survivors: an application of the Theory of Planned Behavior.

Background: Despite evidence of the benefits of exercise in cancer survivors, exercise participation rates tend to decline after treatments. Few studies have examined the determinants of exercise in less common cancer sites. In this study, we examined medical, demographic, and social cognitive correlates of exercise in endometrial cancer survivors using the Theory of Planned Behavior (TPB).

Lower excess postexercise oxygen consumption and altered growth hormone and cortisol responses to exercise in obese men.

Context: Obesity is associated with altered patterns of substrate utilization at rest and during exercise.

Objective: The relationship between obesity and fat oxidation during recovery from exercise was examined.

Hypothesis: The postexercise shift toward fat oxidation is blunted in the obese state, reflected by higher respiratory exchange ratio (RER), blunted GH, and increased cortisol values compared with lean controls.

Associations among exercise, body weight, and quality of life in a population-based sample of endometrial cancer survivors.

Objectives: Lack of exercise and excess body weight may exacerbate treatment-related declines in quality of life (QoL) in endometrial cancer survivors. The primary purpose of this study was to examine the associations among exercise, body weight, and QoL in a population-based sample of endometrial cancer survivors.

Methods: Participants were 386 endometrial cancer survivors residing in Alberta, Canada who completed a mailed survey that assessed self-reported exercise, height, and weight to calculate body mass index (BMI) and QoL using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) scale.

Randomized controlled trial of exercise and blood immune function in postmenopausal breast cancer survivors.

The objective was to determine the effects of exercise training on changes in blood immune function in postmenopausal breast cancer survivors. Fifty-three postmenopausal breast cancer survivors were randomly assigned to an exercise (n=25) or control group (n=28). The exercise group trained on cycle ergometers three times per week for 15 wk.

Effects of prolonged exercise to exhaustion on left-ventricular function and pulmonary gas exchange.

The purpose of this study was to simultaneously examine left-ventricular (LV) function and pulmonary gas exchange during prolonged constant-rate cycling in an attempt to explain the exercise-induced impairment in gas exchange. Eleven competitive cyclists rode their racing bicycles on a computerized cycle trainer at 25 W below the lactate threshold until exhaustion (exercise time = 2.51 +/- 0.

Exercise issues in older cancer survivors.

Older cancer survivors experience the combined deleterious effects associated with aging and a cancer diagnosis. The purpose of the present paper is to review the potential role of physical exercise in attenuating the effects of cancer and its treatments in older cancer survivors. Noting the limited direct research on exercise in older cancer survivors, we review the literature on: (a) older adults in general; and (b) cancer survivors in general.

Exercise motivation and adherence in cancer survivors after participation in a randomized controlled trial: an attribution theory perspective.

The purpose of this study was to examine postprogram exercise motivation and adherence in cancer survivors who participated in the Group Psychotherapy and Home-Based Physical Exercise (GROUP-HOPE; Courneya, Friedenreich, Sela, Quinney, & Rhodes, 2002) trial. At the completion of the GROUP-HOPE trial, 46 of 51 (90%) participants in the exercise group completed measures of attribution theory constructs. A 5-week follow-up self-report of exercise was then completed by 30 (65%) participants.

Randomized controlled trial of exercise training in postmenopausal breast cancer survivors: cardiopulmonary and quality of life outcomes.

Purpose: To determine the effects of exercise training on cardiopulmonary function and quality of life (QOL) in postmenopausal breast cancer survivors who had completed surgery, radiotherapy, and/or chemotherapy with or without current hormone therapy use.

Methods: Fifty-three postmenopausal breast cancer survivors were randomly assigned to an exercise (n = 25) or control (n = 28) group. The exercise group trained on cycle ergometers three times per week for 15 weeks at a power output that elicited the ventilatory equivalent for carbon dioxide.
