Fatigue is one of the most debilitating side effects experienced by people undergoing cancer treatment, and often persists long after treatment ends. But new research suggests a path toward relief: individualized exercise programs. A systematic review and meta-analysis, recently published in Sports Medicine – Open, demonstrates that tailoring exercise prescriptions to a patient’s individual needs and adjusting them based on how they’re feeling can significantly reduce cancer-related fatigue. This approach to exercise oncology represents a shift toward more personalized care, acknowledging that a one-size-fits-all approach simply doesn’t work.
The study, led by Brent Cunningham, an Associate Lecturer at The University of Queensland and PhD candidate at the University of the Sunshine Coast, examined data from 63 studies encompassing 4,472 participants. Cunningham and his team sought to understand not only the importance of individualizing exercise for cancer patients, but also what that individualization actually looks like in practice, and whether it translates to measurable improvements in outcomes. The findings highlight a gap between recognizing the need for personalized exercise and consistently implementing it in research and clinical settings.
The Challenge of Individualization in Cancer Exercise
Whereas the benefits of exercise during and after cancer treatment are well-established – including improved physical function, reduced anxiety, and enhanced quality of life – the study reveals that truly individualized exercise programs are surprisingly rare. Researchers found that only 49% of the studies reviewed provided enough detail to allow for replication of their methods. Most programs focused on initial assessments, using objective measures to create a baseline plan, but lacked ongoing adjustments based on a patient’s daily condition.
“We found that most individualization happened at baseline, using things like fitness tests,” explains Cunningham. “But what about how someone is feeling *today*? Are they having a excellent day or a terrible day? Are they experiencing more pain or nausea? Those factors significantly impact a person’s ability to exercise effectively.”
The concept of “autoregulation” – adjusting exercise prescription based on an individual’s readiness to train – was explicitly reported in a mere 3% of the studies analyzed. This represents despite growing evidence suggesting that autoregulation is a key component of successful exercise programs for a variety of populations, including those with chronic health conditions.
Subjective Assessments and Fatigue Reduction
The meta-analysis revealed a crucial link between individualized approaches and positive outcomes. Specifically, the researchers found that individualizing exercise using subjective assessments – asking patients about their energy levels, pain, and mood – and making adjustments between sessions were both significantly associated with reduced fatigue. This finding underscores the importance of listening to patients and incorporating their feedback into the exercise plan.
“Cancer and its treatment cause a lot of day-to-day variability,” Cunningham notes. “People can have good days and bad days, and their exercise program needs to reflect that. If someone is feeling particularly fatigued, it’s okay to scale back the intensity or duration of their workout. The goal is to identify a level of activity that is challenging but manageable, and that doesn’t exacerbate their symptoms.”
Implications for Future Research and Clinical Practice
The study’s authors emphasize the need for more rigorous reporting of exercise individualization methods in future research. They propose a standardized approach to documenting the “why, when, and how” of exercise prescription, which would allow for better comparison of studies and facilitate the development of evidence-based guidelines.
The research team included Jamie E. Chong, Ciaran M. Fairman, Matthew D. Jones, Tina L. Skinner, and Grace L. Rose, alongside Cunningham.

For individuals navigating cancer treatment, this research offers a hopeful message: exercise can be a powerful tool for managing fatigue and improving quality of life. However, it’s crucial to work with a qualified exercise professional who understands the unique challenges faced by cancer patients and can develop a program tailored to their individual needs. Finding an Accredited Clinical Exercise Physiologist (ACSM) is a good starting point.
Looking ahead, Cunningham’s research team is continuing to investigate the role of autoregulation in exercise oncology, with a focus on developing practical tools and strategies for clinicians and patients. The next step involves evaluating the long-term effects of autoregulated resistance training programs for cancer survivors and patients currently undergoing treatment.
