Physical Activity for Breast and Prostate Cancer Survivors
(PACE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine how different physical activity strategies can help control blood sugar levels in breast and prostate cancer survivors currently undergoing hormone therapies. It compares the effects of short, frequent activity bouts, such as walking after meals or spreading small activity "snacks" throughout the day, with more traditional exercise routines. The trial is open to breast cancer survivors using aromatase inhibitors and prostate cancer survivors on androgen deprivation therapy who have been sedentary (engaging in less than 30 minutes of exercise per week) and have a higher body weight (BMI of 25 or more). As an unphased trial, this study offers participants the chance to explore innovative exercise strategies that could enhance their health and well-being.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it does require that participants are already using hormone therapies like aromatase inhibitors or androgen deprivation therapy. If you are using diabetes medications, you cannot participate in this trial.
What prior data suggests that these physical activity strategies are safe for cancer survivors?
Research has shown that physical activity is generally safe for cancer survivors. For the spread-out physical activity plan, studies have found that exercise is usually well-tolerated by breast and prostate cancer survivors, with side effects being rare and most individuals able to participate without issues.
Evidence suggests that short activity breaks, such as walking, can enhance fitness and strength in cancer survivors without causing harm. It's an easy and safe way to stay active.
Regarding muscle strengthening, studies confirm these exercises are safe. They do not worsen conditions like lymphedema (swelling from fluid buildup) in breast cancer survivors and can even improve muscle strength.
Overall, these activities are safe and beneficial for cancer survivors, with few reports of negative effects.12345Why are researchers excited about this trial?
Researchers are excited about these physical activity strategies for breast and prostate cancer survivors because they explore diverse ways to incorporate movement into daily life, which could enhance recovery and quality of life. Unlike traditional exercise routines that focus on longer, continuous sessions, these strategies include innovative approaches like "Physical Activity Snacks," which involve short, frequent bursts of activity, and "Dispersed Physical Activity," which spreads movement throughout the day. Additionally, the "Muscle Strengthening" routine offers targeted exercises to improve muscle health through convenient video-guided sessions. By varying the timing and type of physical activity, these methods may offer more flexibility and better adherence, potentially leading to improved health outcomes for cancer survivors.
What evidence suggests that these physical activity strategies could be effective for cancer survivors?
Research has shown that exercise benefits cancer survivors in significant ways. For individuals with breast and prostate cancer, strong evidence indicates that being active after diagnosis can reduce the risk of death, cancer recurrence, and other health issues. In this trial, participants will follow different physical activity strategies. One group will engage in short bursts of activity throughout the day, known as "PA snacks," which might lower blood sugar levels as effectively as traditional 30-minute workouts. Another group will focus on strength training, which can enhance fitness, improve quality of life, and reduce cancer-related fatigue. These alternative exercise methods may be easier and more appealing for cancer survivors, offering similar benefits with greater flexibility.13678
Are You a Good Fit for This Trial?
This trial is for sedentary breast and prostate cancer survivors who are on hormone therapies. It's designed to test if short bursts of physical activity can help manage blood sugar better than no exercise or standard 30-minute workouts. Participants should be willing to try different exercise routines.Inclusion Criteria

Trial Overview
The study compares the effects of 'Physical Activity Snacks', dispersed post-meal activities, and muscle strengthening exercises against a no-exercise control group and standard fasting or post-meal workouts on blood sugar levels in cancer survivors.
How Is the Trial Designed?
5
Treatment groups
Experimental Treatment
Participants will perform 30 minutes of walking at a self-selected pace 30 minutes after the start of the first meal in the morning.
Participants will perform 30 minutes of walking at a self-selected pace 15 minutes prior to consumption of first meal in the morning (including cream/sugar/milk in coffee or tea).
Participants will perform 2 minutes of walking or marching on the spot at a self-selected pace every 30 minutes throughout the day for 7.5 waking hours.
Participants will perform 30 minutes of muscle strengthening exercises targeting the major muscle groups of the whole body performed by following along with a video, to start 30 minutes after the start of the first meal in the morning.
Participants will perform 10 minutes of walking at a self-selected pace 30 minutes after the start of each main meal throughout the day (i.e., three bouts total).
