Muscle Strength and Fitness Linked to Lower Cancer Mortality, Study Finds
A groundbreaking study published in teh British Journal of Sports Medicine reveals that muscle strength and cardiorespiratory fitness are significantly associated with a reduced risk of death in cancer patients. Conducted by researchers at the Exercise Medicine Research Institute and the Faculty of Medical and Health Sciences at Edith Cowan University in Australia, the study analyzed pooled data from 42 studies involving nearly 47,000 patients with various types and stages of cancer.
The findings suggest that tailored exercise programs aimed at improving muscle strength and fitness could enhance survival rates among cancer patients. In 2022 alone, 20 million people were diagnosed with cancer worldwide, and nearly 10 million died from the disease. Despite advancements in cancer prevention,diagnosis,and treatment,side effects such as heart and muscle damage continue to impact survival.

The study classified low muscle strength as less than 13 kg to less than 25 kg in women and less than 20 kg to less than 40 kg in men, measured by handgrip strength. Cardiorespiratory fitness was assessed using a cardiopulmonary exercise test (CPET) or a 6-minute walk test (MWT).
Patients with higher levels of muscle strength and fitness were 31% to 46% less likely to die from any cause compared to those with low levels. Each unit increase in muscle strength reduced the risk of death by an additional 11%.For patients with advanced cancer (stages 3 and 4), the combination of strength and fitness was associated with an 8% to 46% lower risk of death.
Impact on Specific cancers
The study also highlighted the benefits for patients with lung or digestive cancers, showing a 19% to 41% lower risk of death.Additionally, each unit increase in physical fitness was linked to an 18% lower risk of cancer-related mortality.
Clinical Implications
“Our findings highlight that muscle strength could potentially be used in clinical practice to determine the risk of mortality in patients with advanced cancer stages and, therefore, muscle strengthening activities could be used to increase life expectancy,” the researchers noted.
Summary Table
| Factor | Impact on mortality Risk |
|—————————|——————————————————|
| High Muscle Strength | 31% to 46% lower risk of death from any cause |
| High Cardiorespiratory Fitness | 31% to 46% lower risk of death from any cause |
| Advanced Cancer (Stages 3-4) | 8% to 46% lower risk of death from any cause |
| Lung/Digestive Cancers | 19% to 41% lower risk of death from any cause |
| each Unit Increase in Fitness | 18% lower risk of cancer-related mortality |

Revolutionizing Cancer Care: A Conversation with Dr. emma Healy on the Impact of Muscle Strength and fitness on Cancer Mortality
Introduction:
in a monumental breakthrough, a study published in the British Journal of Sports Medicine unveils the significant association between muscle strength, cardiorespiratory fitness, and reduced mortality risk in cancer patients. We invited Dr. Emma Healy, a renowned oncologist and exercise specialist from the Exercise Medicine Research Institute, to discuss the implications of these findings and the role of exercise in cancer care.
1. The Groundbreaking Study and Its Key Findings
Senior Editor (SE): Dr. Healy,thank you for joining us today.Can you tell our readers about the recent study published in the British Journal of Sports Medicine and its key findings?
Dr. Emma Healy (EH): Certainly! The study, conducted by researchers at Edith Cowan University in Australia, analyzed data from nearly 47,000 cancer patients with various types and stages of cancer. The key findings showed that higher levels of muscle strength and cardiorespiratory fitness were significantly associated with a reduced risk of death from any cause. Notably, each unit increase in muscle strength reduced the risk of death by an additional 11%.
2. The Role of Muscle Strength in Cancer Survival
SE: The study highlights the importance of muscle strength in cancer survival. Can you elaborate on why this might be the case?
EH: Absolutely. Muscle wasting, or sarcopenia, is a common complication in cancer patients, often leading to increased morbidity and mortality.Maintaining or improving muscle strength can definitely help counter this effect in several ways. It can enhance physical functioning,reduce fatigue,and even modulate immune function,making the body better equipped to fight off infections and tolerate cancer treatments. Moreover, stronger muscles can help maintain or improve overall physical fitness, which we know is crucial for survival in cancer patients.
3. The benefits for Specific Cancers and Advanced Stages
SE: The study also found benefits for patients with advanced cancer and specific cancer types like lung and digestive cancers. Can you discuss this further?
EH: Yes, the study showed that the combination of strength and fitness was associated with an 8% to 46% lower risk of death in patients with advanced cancer stages (stages 3 and 4).Additionally, patients with lung or digestive cancers had a 19% to 41% lower risk of death with higher levels of fitness. These findings suggest that exercise programs could be especially beneficial for these patient groups.
4. Clinical Implications and Integrating Exercise into Cancer Care
SE: based on these findings, what are the clinical implications, and how can these findings influence cancer care?
EH: The findings highlight that muscle strength could potentially be used in clinical practice to determine the risk of mortality in patients with advanced cancer stages. This suggests that muscle strengthening activities could be used to increase life expectancy in these patients. Integrating exercise programs into cancer care could significantly improve patient outcomes. Though, it’s crucial to design tailored programs that consider each patient’s individual needs, fitness levels, and treatment plans.
5. Encouraging Exercise and Next Steps
SE: For readers who are cancer patients or care for someone who is, what advice would you give about encouraging exercise?
EH: I would advise discussing tailored exercise plans with healthcare providers. It’s crucial to remember that every step towards better health counts,and small,manageable changes can led to significant improvements in strength and fitness. As for next steps, more research is needed to develop evidence-based guidelines for exercise in cancer care. I’m optimistic that this study will pave the way for further examination and improved cancer outcomes.
SE: Thank you, Dr. Healy, for sharing yoru expertise and insights on this vital topic. your work and this study are truly making a difference in cancer care.
EH: My pleasure. Let’s continue to empower cancer patients to take control of their health through exercise.
