Can I exercise during Prostate Cancer treatment

Exercise During Prostate Cancer Treatment: What the Evidence Shows

Yes, you can and should exercise during prostate cancer treatment. In fact, current medical guidelines strongly recommend it. Let me explain what the research shows and how to approach this safely.

What the Medical Guidelines Say

According to ASCO (American Society of Clinical Oncology), medical oncologists should refer patients receiving cancer treatment to exercise programming to address common symptoms and side effects. This isn't just a suggestion—it's an evidence-based recommendation from one of the most important clinical oncology organizations in the US.

The American Cancer Society and ACSM (American College of Sports Medicine) guidelines similarly recommend that patients undergoing active cancer treatment include both aerobic exercise and resistance training as part of their care plan.

Why Exercise Matters During Treatment

Exercise during prostate cancer treatment can help you:

• Mitigate treatment side effects - Cancer treatments can cause significant fitness decline (you can lose 5-20% of your fitness in just three months of chemotherapy), but exercise helps prevent this
• Counteract accelerated aging - Treatment can make you feel like you've aged 10 years in a few months; exercise helps slow this process
• Maintain muscle mass and strength - This is especially important if you're on androgen deprivation therapy (ADT/hormone therapy), which causes muscle loss
• Support your immune system - Exercise enhances immune function, which helps your body fight cancer
• Improve quality of life - Reduces fatigue, anxiety, and depression
• Potentially improve treatment response - Emerging research suggests exercise may enhance how well your body responds to cancer therapies

What Does the Research Show?

Recent clinical trials provide encouraging evidence:

For localized prostate cancer: A phase 1 trial studied 53 men scheduled for prostate cancer surgery who were assigned different exercise doses (ranging from 90 to 450 minutes per week). The study found that 225 minutes of exercise per week showed biological activity against the cancer - meaning it actually affected tumor markers like PSA and Ki-67 (a measure of cancer cell growth). Importantly, higher doses didn't provide additional benefits, and lower doses (90-150 minutes) showed no biological effect.

For metastatic prostate cancer: A major randomized controlled trial (funded by the Movember Foundation) with 154 patients across 10 countries studied men with stage 4 prostate cancer on hormone therapy. The study showed that supervised, high-intensity exercise was safe even in advanced disease, with no serious exercise-related adverse events. This is important because many patients were previously told to avoid vigorous exercise with advanced cancer.

How exercise changes your internal chemistry: Research shows that after 6 months of exercise training, men with prostate cancer develop higher levels of "myokines" (proteins released by muscle that signal throughout the body). When researchers applied these myokines to living prostate cancer cells in the laboratory, they saw a 20% reduction in cancer cell growth and increased cancer cell death.

Recommended Exercise Targets

Here's what current guidelines suggest:

During active treatment:

• Aerobic exercise: Up to 90 minutes per week of moderate-intensity activity
• Resistance training: Twice weekly
• Balance training: Some balance work each week

For general wellness and reducing recurrence:

• Aerobic exercise: Increase to 115 minutes weekly
• Resistance training: Twice weekly
• Adequate protein: 1.2 grams per kilogram of body weight daily (especially important if on hormone therapy)

Important: Personalize Your Exercise

One-size-fits-all exercise recommendations aren't enough for cancer patients. Your exercise plan should be tailored to:

• Your current treatment stage
• Your fitness level before diagnosis
• Your specific goals (muscle preservation, fatigue management, fitness)
• Your cancer type and treatment type
• Any bone metastases (cancer spread to bones)
• How you're feeling day-to-day

For example:

• If you're on androgen deprivation therapy (ADT): You need intensive resistance training 2-3 times per week with progressive weight increases to preserve muscle mass
• If you have bone metastases: You can still do resistance training, but your exercise prescription should avoid excessive loading of affected sites
• If you're experiencing severe fatigue: Start with minimal movement and gradually increase as your energy improves

The 225-Minute Prostate Cancer Protocol

Based on the research, here's how the 225 minutes per week breaks down:

Five days per week, approximately 45 minutes per session, BUT with varying intensity:

• Some days: 20-30 minutes of high-intensity work (zone 3-4 workouts)
• Other days: 45-60 minutes of lower-intensity recovery sessions (zone 1-2)
• This "non-linear" approach means you're not doing the same thing every day—you're varying intensity and duration to create different physiological responses

This is similar to how marathon runners train: you don't just do long, slow runs. You mix in interval training, hill workouts, and speed work.

Safety Considerations

Exercise is safe during prostate cancer treatment when properly supervised. A major study of 620 adverse events during exercise in cancer patients found that all exercise-related events were grade 3 or less (meaning no hospitalizations or deaths). Common side effects were minor muscle soreness or strains.

However, you should:

• Work with an exercise physiologist or oncology-trained fitness professional
• Get clearance from your oncology team before starting
• Start gradually if you're sedentary
• Monitor how you feel and adjust intensity accordingly
• Avoid extreme amounts of exercise (excessive exercise can negatively affect your immune system)

Questions to Ask Your Healthcare Team

1. Am I cleared to exercise given my current treatment plan?
2. Should I work with an exercise physiologist or certified cancer fitness trainer?
3. Are there any specific exercises I should avoid based on my cancer stage or treatment?
4. How should I adjust my exercise if I have bone metastases?
5. What's the right balance of aerobic exercise and resistance training for my situation?
6. How much protein should I be eating to support muscle maintenance during exercise?

Finding Professional Support

Look for oncology rehabilitation and exercise programs in your area through Moving Through Cancer (movingthrough cancer.org), which has a registry of over 2,100 programs across the United States and includes a triage tool to help match you with appropriate programming.

If you're on androgen deprivation therapy and struggling with muscle loss despite exercise, researchers like Dr. [removed] Jones at Memorial Sloan Kettering are actively studying how to optimize exercise prescriptions for this specific situation.

Key Takeaway

Exercise isn't just safe during prostate cancer treatment—it's a powerful tool that can help you maintain fitness, preserve muscle, manage side effects, and potentially improve how your body responds to treatment. The key is working with your healthcare team to create a personalized plan that matches your specific situation, not just following generic guidelines.
