Assisted Exercise in Obese Endometrial Cancer Patients
REWARD (Revving-Up Exercise for Sustained Weight Loss by Altering Neurological Reward and Drive): A Randomized Trial of Assisted Exercise in Obese Endometrial Cancer Patients
Study Overview
Status
Detailed Description
Primary Objective:
To evaluate changes in body weight, fitness, bi-manual dexterity, exercise motivation and self-reported eating behavior (via questionnaires) before and after a 16-week exercise intervention (EOT) and 12 and 24 weeks post-EOT, in obese EC patients who will be randomized to perform 'assisted' or voluntary exercise.
Secondary Objectives:
Objective 1: To objectively examine food behavior as determined by neuronal response to high- versus low-calorie visual stimuli under fasted (hunger) and fed (satiated) states and stop/go signaling (SST) in fed states in brain regions of interest (reward and motivation circuitry) using blood oxygenation level dependent (BOLD) functional MRI before and after a 16-week exercise intervention (EOT) and 12 and 24 weeks post-intervention in obese EC patients performing 'assisted' and voluntary exercise.
Objective 2: To examine the modification of the neuronal response to high vs. low calorie food images in regions of interest by polymorphisms in key genes (e.g., dopamine receptor and dopamine transporter) and serum biomarkers (e.g., leptin, BDNF) involved in regulating homeostatic and non-homeostatic energy systems.
Patients will be randomized to receive either the assisted exercise (n=60) or voluntary exercise (n=60) group. Subjects in the voluntary group will exercise on a stationary recumbent exercise cycle and pedal at their preferred rate. Subjects in the assisted exercise group will cycle on the same stationary exercise bike; however, a motor will provide assistance to the patient in order to maintain a pedaling rate 35% greater than their voluntary rate. Subjects in the exercise groups will complete 45 minute to 1-hour sessions, three times per week for eight weeks. The control group will be asked to complete all exercise, body composition and fMRI testing similar to the exercise groups.

Intervention / Treatment |
---|---|
EXPERIMENTAL: 'Assisted-Rate' Exercise Intervention
Subjects in the assisted exercise group will cycle on the same stationary exercise bike; however, a motor will provide assistance to the patient in order to maintain a pedaling rate 35% greater than their voluntary rate.
Subjects in the exercise groups will complete 45 minute to 1-hour sessions, three times per week for eight weeks.

Imaging data will be acquired on a Siemens 3.0T Wide-Bore Verio MRI scanner.
Other Names:
Patients will be asked to fast for approximately 12 hours and will have approximately 2 Tbs. of blood drawn at baseline and the end of treatment (EOT).
Other Names:

EXPERIMENTAL: 'Voluntary-Rate' Exercise Intervention
Subjects in the voluntary group will exercise on a stationary recumbent exercise cycle and pedal at their preferred rate.
Subjects in the exercise groups will complete 45 minute to 1-hour sessions, three times per week for eight weeks.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Change in Body Composition from baseline
Time Frame: at 4 weeks after exercise intervention(EOT)
|
Body fat, lean mass and bone mass will be measured with a Lunar iDXA™ (GE Healthcare, Madison, WI.
BMI will be computed (weight in kg divided by square of height in meters) and categorized as: < 18.5 (underweight), 18.5 to 24.9 (normal weight), 25.0 to 29.9 (overweight)
|
at 4 weeks after exercise intervention(EOT)
|
Change in Motivation to Exercise from baseline
Time Frame: 24 weeks after exercise intervention (EOT)
|
Evaluate motivation to exercise using the Exercise Motivations Inventory (EMI-2) 122 and the Intrinsic Motivational Inventory (IMI) modified for exercise.
Past physical activity habits will be assessed with the Godin Leisure-Time Exercise (LSI) questionnaire.
|
24 weeks after exercise intervention (EOT)
|
Change in Eating Behavior from baseline
Time Frame: 24 weeks after exercise intervention (EOT)
|
Eating behavior will be assessed using the Three-Factor Eating Questionnaire (TFEQ).
The TFEQ includes 51 items and addresses three dimensions of human eating behavior; restraint, disinhibition, and perceived hunger.
|
24 weeks after exercise intervention (EOT)
|
Change in Quality of Life (QoL)from baseline
Time Frame: 24 weeks after exercise intervention (EOT)
|
The Functional Assessment of Cancer Therapy - General (FACT-G) is a 27-item core questionnaire evaluating various domains of QoL including, physical, functional, family-social, and emotional well-being.
The FACT-En is a 16-item subscale specific for endometrial cancer (EC) and assesses hormone withdrawal, pelvic symptoms, and possible adjuvant therapy side effects.
Short-form Medical Outcomes (SF-36) consists of 36 questions scored on a Likert scale, producing overall physical and mental component summary measures.
|
24 weeks after exercise intervention (EOT)
|
Change in Depression from baseline
Time Frame: 24 weeks after exercise intervention (EOT)
|
The Beck Depression Inventory (BDI) is a 21-item, Likert-scaled instrument of depressive symptoms that is well-validated and frequently used in lifestyle research studies.
Each item is rated on a 4- point scale ranging from 0 to 3 (higher scores are associated with greater symptoms).
|
24 weeks after exercise intervention (EOT)
|
Exercise Session Adherence
Time Frame: 24 weeks after exercise intervention (EOT)
|
Barriers to adhering to the exercise protocol will be assessed prospectively using an elicitation procedure similar to that suggested in the theory of planned behavior, whereby an open-ended question is asked to solicit the barrier without any preconceived notion of what the barrier might be.
Specifically, participants in the exercise groups will be asked to book their weekly supervised exercise sessions with the Exercise Specialist/Physiologist. Participants cancelling an exercise session or requesting to be removed from the study will be asked why they are no longer interested in completed the program.
