However, a new study has pinpointed a specific workout routine shown to slow the growth of cancer cells, even after just one session.
The study, published earlier this summer in the journal Breast Cancer Research and Treatment, looked at 32 patients who had been treated for breast cancer, ranging from stage one to stage three, at least four months beforehand.
However, high cytokine levels can trigger excess inflammation, which damages cell DNA and increases the risk of cancer cells forming.
Breast cancer strikes 311,000 American women every year and kills 42,000, according to the American Cancer Society.
Bettargia said: ‘Breast cancer is the most common cancer among women and the leading cause of cancer-related death in women.
The most well-established health advice is that regular exercise is essential for preventing obesity, aging, and chronic illnesses.
Exercise just a few days a week can also reduce the risk of dying from cancer, according to mountains of research.
A recent study, however, identified a particular exercise regimen that has been demonstrated to inhibit the growth of cancer cells, even after just one session.
A single session of either resistance training, like lifting weights, or high-intensity interval training (HIIT), which consists of brief, intense bursts of exercise interspersed with short rest periods, was administered to women who had survived breast cancer by Australian researchers.
Participants’ blood myokines increased by up to 47% right after a 45-minute resistance or HIIT session, they discovered.
During physical activity, skeletal muscle cells release proteins called myokines, which facilitate communication between muscles and the rest of the body.
Additionally, they have been demonstrated to control metabolism and inhibit proteins that lead to inflammation, which is a major factor in the development of cancer cells.
According to the team’s estimation, the increased production of myokines could potentially slow the growth of cancer by 20 to 30 percent.

“By demonstrating anti-cancer effects at the cellular level, our results provide a potential explanation for why exercise reduces the risk of cancer progression, recurrence, and mortality,” Francesco Bettariga, lead study researcher and PhD candidate at Edith Cowan University in Australia, told the Daily Mail.
Even though our study has limitations and more in vivo research is required, these results show that exercise may help cancer patients have better survival rates. “.”.
The study examined 32 patients who had received treatment for breast cancer from stage one to stage three at least four months prior, and it was published earlier this summer in the journal Breast Cancer Research and Treatment.
Stage two cancer accounted for 41% of the total.
Participants had a body mass index (BMI) of 28, which is regarded as overweight but not obese, and an average age of 59.
Eight repetitions of five sets of exercises targeting the major muscle groups were performed by participants in the resistance training group.
They included lunges, lateral pulldowns, shoulder presses, seated rows, chest presses, leg presses, leg extensions, and leg curls.
Between sets, participants in this group were given a rest period of one to two minutes.
Participants in the HIIT group used a minimum of three of the following exercise machines: a cross-trainer, a stationary bike, a treadmill, and a rower to complete seven 30-second bursts of high-intensity exercise.
They rested for three minutes in between each set.
In order to ascertain which exercise could have a greater cancer-suppressive effect, Bettariga told this website: “We chose two different exercise modalities—resistance and aerobic training—because they offer different physiological benefits: resistance training improves muscle strength, while aerobic training enhances cardio-respiratory fitness.”.
In order to ascertain whether increased intensity could enhance these anti-cancer effects, we specifically employed a high-intensity workout. “…
The combined exercise time for both groups was roughly forty-five minutes.
Additionally, blood tests were administered to participants three times: prior to, right after, and half an hour after their workouts.
The researchers discovered that participants’ blood myokine levels rose after completing the resistance or HIIT regimen just once.
Following exercise, the myokine IL-6 increased by 47% in the HIIT group, resulting in the biggest jump. A protein called IL-6, which is released from muscles during exercise, is essential for immune function.
The myokin that controls tissue growth, decorin, increased by 23% in the resistance group, while IL-6 increased by 9%.
After participants finished their workout, the team observed that myokine levels remained elevated but gradually decreased over time.
Based on findings, scientists calculated that the myokine levels generated during exercise could inhibit the growth of cancer cells by 20–30%.
Myokines have been demonstrated to inhibit cytokines, which are inflammatory proteins. In order to manage inflammation, immune cells release cytokines.
However, excessive inflammation brought on by high cytokine levels can harm cell DNA and raise the possibility of the formation of cancer cells.
“After just one exercise session, we discovered that both resistance training and HIIT increased the release of myokines with anti-cancer properties,” Bettariga said. In [lab testing], we then noticed a decrease in cancer cell growth of up to 30%.
The fact that the effects of both modalities were similar was noteworthy and suggests that exercise intensity, not the kind of exercise, is the primary factor causing these anti-cancer changes. “.”.
According to the American Cancer Society, 42,000 women in America lose their lives to breast cancer each year, while 311,000 are affected.
Even though the disease typically has a high survival rate of 92%, if cancer cells spread to other areas, that rate could fall as low as 33%.
Additionally, it is becoming more prevalent among young women, with rates rising by 0.8 percent annually between 2000 and 2019, according to one study. This increase has been linked by experts to early menstruation and hormone-disrupting chemicals, which can increase exposure to hormones like estrogen that can cause breast cancer.
It’s uncertain whether the new study’s encouraging findings for breast cancer would apply to other types of the illness.
According to Bettargia, breast cancer is the most prevalent type of cancer in women and the main reason why they die from it. Our findings are extremely relevant to the millions of women who are living with breast cancer, as no studies with this particular design had been done in this population, which was surprising. “…
There were a number of restrictions, such as the small sample size and the exclusive focus on one type of cancer.
The team’s next goal, according to Bettariga, is to look into these effects in groups of cancer patients and in other types of cancer.
Examining how regular, sustained exercise regimens affect these anti-cancer reactions is now necessary, he stated. We also want to investigate other mechanisms, especially the immune system’s function, which is vital in regulating the growth of cancer cells. “…
