The Power of Strength: Why Resistance Training Matters for Cancer Patients
Cancer treatment can be a tough journey, but your body has incredible potential for resilience and recovery. While many people focus on cardio exercises like walking or cycling, resistance training is equally crucial. In fact, when combined with cardiovascular exercise, strength training can support your body in ways that can have a significant impact on both your treatment outcomes and your overall well-being.
Understanding the Science Behind Strength: How Does Resistance Training Help Your Body?
Think of your body as a garden. Cancer and its treatments can be like harsh weather—storms that damage the soil, strong winds that weaken the plants, or droughts that drain their strength. Cardio exercise, such as walking, is like watering the garden to keep the plants alive. But resistance training is different. It’s like reinforcing the soil, fortifying the roots, and ensuring that the plants not only survive but thrive. When you incorporate resistance training into your routine, you’re giving your body the tools to recover stronger and more resilient.
What Role Does Resistance Training Play in Fighting Cancer-Related Fatigue?
Cancer-related fatigue is one of the most challenging and persistent symptoms cancer patients experience. It’s not the kind of tiredness you can overcome with a good night’s sleep—it can affect your body, mind, and spirit. However, resistance training has been shown to help fight this fatigue.
By strengthening your muscles, resistance exercise not only helps you fight physical fatigue but also boosts your mood and energy levels. Studies have found that regular resistance training improves muscle mass, which in turn reduces feelings of tiredness. A study published in Supportive Care in Cancer (2023) found that resistance exercise can significantly reduce cancer-related fatigue and improve overall quality of life, helping you feel more energized and capable in your day-to-day life (PubMed Source).
Can Resistance Training Boost Your Immune System?
Your immune system is a powerful defense network that plays a critical role in protecting your body from infection and disease—an especially important function when you’re facing cancer. In fact, a strong immune system is essential in fighting cancer cells and supporting the effectiveness of treatments like chemotherapy and immunotherapy.
Resistance training, though commonly known for building muscle, has been shown to improve immune function in cancer patients in significant ways. But how exactly does it work?
- Boosting T-cell and NK-cell Activity: One of the ways resistance training helps your immune system is by enhancing the activity of T-cells and natural killer (NK) cells. These immune cells are crucial for identifying and attacking abnormal or cancerous cells. Regular resistance exercise has been found to improve the function of these immune cells, which means your body becomes more effective at detecting and eliminating harmful cells.
- Increasing Immune Cell Circulation: Resistance training increases circulation throughout your body, which helps immune cells travel more efficiently through your bloodstream. This enhanced circulation allows immune cells to reach areas of the body that need them most, providing faster protection from infection and better immune surveillance.
- Reducing Systemic Inflammation: Cancer treatment, as well as the disease itself, can cause inflammation in the body, which can weaken the immune system. Chronic inflammation may also contribute to tumor growth and metastasis. By engaging in resistance exercise, you reduce systemic inflammation, which in turn supports the body’s natural defenses and promotes better overall health.
Research published in Frontiers in Physiology (2022) highlights these benefits, showing that resistance training not only increases the number of immune cells but also reduces markers of inflammation, leading to improved immune function in cancer patients undergoing treatment (PubMed Source).
How Does Resistance Training Help Maintain Muscle Strength and Body Composition?
One of the most common side effects of cancer treatments is muscle loss. This process, known as cachexia, can make everyday tasks feel much harder. Muscle loss can impact your mobility, strength, and overall quality of life. But here’s where resistance training comes in.
Studies have shown that resistance training can:
- Increase lower-limb strength: This is essential for maintaining your ability to walk, climb stairs, and move with ease. Even modest increases in strength can make a huge difference in your mobility.
- Maintain lean body mass (LBM): Strength training helps to combat the muscle-wasting effects of cancer treatments by building and preserving muscle.
- Reduce body fat: Research shows that resistance training can help reduce body fat, which helps improve your body composition and overall health.
Strengthening your muscles through resistance training isn’t just about building strength—it’s about giving your body the resilience it needs to maintain its function and improve your quality of life. This was demonstrated in a comprehensive trial published in Journal of Clinical Oncology (2013), which revealed that resistance training significantly improved muscular strength, lean body mass, and reduced body fat in cancer patients undergoing therapy (PubMed Source).
Can Resistance Training Improve Your Bone Health?
Certain cancer treatments can weaken your bones, increasing the risk of fractures. But resistance training is a weight-bearing exercise that helps strengthen your bones, improve bone density, and reduce the risk of injury. It’s a powerful tool to help protect your skeletal system and keep you strong during and after treatment.
How Can Resistance Training Help Reduce Fatigue?
Fatigue is one of the most difficult challenges that cancer patients face. It’s not just physical tiredness—it can affect your mood, your mental clarity, and your overall sense of well-being. Fortunately, resistance training has been shown to reduce fatigue by improving both your energy levels and mental state.
Here’s how:
- Boosts energy: Studies show that resistance training increases physical strength, which helps improve overall stamina and reduce feelings of tiredness.
- Improves mood: Regular exercise, including strength training, releases endorphins that can elevate your mood and help reduce stress and anxiety.
- Enhances mental clarity: The increase in circulation and oxygenation to your brain through regular exercise can also improve your cognitive function, helping you feel sharper and more alert.
By incorporating strength training into your routine, you can help reduce fatigue and feel more energized, allowing you to better enjoy your daily life.
What Does the Research Say About Resistance Exercise for Cancer Patients?
Recent studies strongly support the use of resistance training for cancer patients, particularly those undergoing neoadjuvant or adjuvant therapy. Research highlights how resistance training can help counteract some of the most challenging side effects of cancer treatment, such as muscle loss, fatigue, and decreased strength.
A systematic review and meta-analysis of 14 studies revealed that:
- Muscular strength significantly increased in patients who participated in resistance exercise, with an average increase of 26.22 kg in lower-limb strength compared to control groups.
- Lean body mass (LBM) increased by an average of 0.8 kg, helping to combat the muscle-wasting effects of cancer treatments.
- Body fat decreased by 1.3 kg on average, improving body composition and overall health.
These findings show that resistance exercise is a powerful and effective way to improve strength, muscle mass, and body composition during cancer treatment. It also offers a proactive way to fight back against the debilitating effects of cancer therapies. (PubMed Source)
