(Press-News.org) MIAMI, FLORIDA (July 22, 2025) – LaShae Rolle, 27, is a competitive powerlifer who could squat 441 pounds, bench 292 pounds and deadlift 497 pounds. She is also a breast cancer survivor and researcher and the lead author on a first-of-its kind study documenting elite-level strength training during active breast cancer treatment.
The study challenges the long-held belief that cancer patients should stick to low- or moderate-intensity exercise and suggests that with individualized and symptom-informed exercise planning, even powerlifting can be safe and beneficial. The findings appear in the July 2024 issue of the journal, Lifestyle Medicine.
Diagnosed in 2024 with stage 2B estrogen receptor-positive breast cancer, Rolle had no genetic predisposition to breast cancer. A competitive powerlifter, strength wasn’t just physical for her — it was personal.
“Strength training has been central to my identity as both an athlete and a rising lifestyle oncology researcher,” she said. “During cancer, it became a way to stay connected to who I am and to feel in control of my body and mind.”
Rolle’s treatment regimen included chemotherapy, a mastectomy and radiation. Beyond that, her research team at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, designed a periodized strength training program to align with her chemo cycles.
High-intensity days were scheduled before chemo infusions and focused on squats, bench press and deadlifts.
Moderate days aligned with mid-cycle sessions involving accessory movements like rows and shoulder presses.
Recovery days included light mobility and therapy work after an infusion.
Each session was adjusted based on real-time symptom tracking and perceived exertion (RPE), creating a feedback loop that prioritized safety and performance.
By the end of treatment, Rolle had retained 93% of her squat strength and 87% of her bench press and deadlift strength. These numbers are rare for someone undergoing chemotherapy and demonstrate the feasibility of high-intensity training when carefully managed.
“I’m proud I kept going,” she says. “Modifying my sessions around chemotherapy cycles helped me keep training safely, and physically, it gave me moments of normalcy even when everything else felt uncertain. . . Documenting everything on video and in a training diary kept me accountable and reminded me I was still strong,” she added. “I am still in awe when I look back at videos of me lifting over 400 pounds in the midst of chemotherapy.”
Changing the Game for Elite Athletes
Previous studies have shown that moderate-intensity aerobic and resistance training can reduce fatigue, improve physical function and alleviate treatment-related symptoms in cancer patients. But that research focused on general populations or survivors, post-treatment. High-intensity modalities like powerlifting remain underexplored.
“LaShae’s journey is a powerful reminder that survivorship is not just about recovery—it’s about reclaiming strength, identity and purpose. Her commitment to powerlifting exemplifies how movement can be a form of healing, empowerment and advocacy.” said Rolle’s primary mentor, Tracy Crane, Ph.D., R.D.N., co-leader of the cancer research program and director of Lifestyle Medicine, Prevention and Digital Health at Sylvester.
For Rolle, being a part of this case study confirmed how critical individualized, flexible programs are for survivors. “I’m absolutely encouraged to keep lifting and to keep advocating for evidence-based exercise as part of cancer care,” she said.

The Sustainability Accelerator at the Stanford Doerr School of Sustainability has selected 41 projects spanning biology, agriculture, electricity, industry, and water. The teams involve 67 faculty from 27 departments across five of the university’s seven schools.
The projects are as diverse as the problems they are trying to solve, ranging from developing plant-based meat alternatives to optimizing low-carbon steel production to helping coastal communities adapt to threats of saltwater ...
Most parents can think back to the first ultrasound image they saw of their unborn child, and may even be able to remember what impression that image had on them. Would their child be an active toddler, a tad bit ornery or stubborn, sweet and cuddly, fiercely independent, or shy and cooperative? New research suggests these initial perceptions may have been formed, at least in part, in response to how the health care provider described the baby during the exam.
These prenatal care experiences play a large role in shaping how parents ...
UNIVERSITY PARK, Pa. — Almost 200 million people, including children, around the world have endometriosis, a chronic disease in which the lining of the uterus grows outside of the uterus. More severe symptoms, such as extreme pain and potentially infertility, can often be mitigated with early identification and treatment, but no single point-of-care diagnostic test for the disease exists despite the ease of access to the tissue directly implicated. While Penn State Professor Dipanjan Pan said that the blood and tissue shed from the uterus each month is often overlooked — and even stigmatized by some — as medical waste, menstrual effluent could enable earlier, ...
The University of Texas at Arlington has launched a $2.1 million supercomputing hub, expanding its capacity to support data-intensive research, including work powered by artificial intelligence and other advanced technologies.
The project was spearheaded by a multidisciplinary team of researchers and leaders from UT Arlington’s College of Engineering and the Office of the Vice President for Research and Innovation, who recognized the growing demand for high-performance computing across campus.
The new hub will allow ...
At a time marked by debate about identity, migration and national cohesion, a new study brings a surprising message: Most Americans want a more ethnically and religiously diverse society than the one they live in today.
The study, published in the journal Ethos, is based on a representative questionnaire survey of 986 American citizens. Participants were asked to assess both the actual and ideal composition of ethnic and religious groups in the United States.
‘We wanted to investigate whether the idea of a multicultural United States still has popular ...
Utica, NY - A groundbreaking new study led by researchers at the Masonic Medical Research Institute (MMRI) has identified a promising molecular target to protect the heart against damage caused by high-fat diet and obesity. The study, published this week in the leading journal Science Signaling, highlights the protein tyrosine phosphatase PTP1B, a nodal enzyme involved in insulin signaling, as a key driver in maladaptive cardiac metabolism and dysfunction under dietary stress.
In obesity and high-fat diet conditions, the heart undergoes a metabolic switch, moving from ...
Researchers led by Gen Kurosawa at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan have used theoretical physics to discover how our biological clock maintains a consistent 24-hour cycle—even as temperatures change. They found that this stability is achieved through a subtle shift in the “shape” of gene activity rhythms at higher temperatures, a process known as waveform distortion. This process not only helps keep time steady but also influences how well our internal clock synchronizes with the day-night cycle. The study was published in PLOS Computational Biology on July 22.

A group of University of Ottawa researchers have already shown how scientists can harness gene therapies to deliver nano-sized treatments for cancer, cardiovascular and other diseases. Unfortunately, the delivery agents in the process do not possess any therapeutic potential and ultimately degrade after acting as the messenger.
So, the researchers asked: can we not develop nanoparticle platforms to be more than just mules?
“Since millions of particles are injected to deliver ...
Public health promotion campaigns can be effective, but they do not tend to be efficient. Most are time-consuming, expensive, and reliant on the intuition of creative workers who design messages without a clear sense of what will spark behavioral change. A new study conducted by Dolores Albarracín and Man-pui Sally Chan of the University of Pennsylvania, government and community agencies, and researchers at the University of Illinois and Emory University suggests that artificial intelligence (AI) can facilitate theory- and evidence-based message selection.
The research group, led by Albarracín, a social psychologist who is the Amy Gutmann ...
