New research proposes that short blasts of extraordinary, physical activity may lessen the growth of colorectal tumor cells.  

As indicated by the American Cancer Society, doctors will analyze more than 100,000 new cases of colon cancer. In addition to this, they will also analyze more than 44,000 cases of rectal cancer in 2019.  

Colorectal cancer may likewise cause more than 50,000 deaths this year, researchers predict. Treatment choices for colorectal cancer differ from localized treatments to systemic, drug-based treatments. 

In any case, new research proposes there is an additional factor that may add to diminishing colorectal cancer growth and improving patient results. This factor is a high-intensity exercise. 

James Devin, from the School of Human Movement and Nutrition Sciences at The University of Queensland in Brisbane, Australia, is the lead author of a group of researchers. He set out to explore the impacts of a short burst of activity on colon cancer cells.  

As Devin and partners clarify, past research has pointed out that repeatedly exercise over a long period of time may help fight off cancer. However, the new examination recommends that even short blasts may have a similarly positive outcome.  

In addition to this, while a few studies have discovered an association between exercise and “significant reductions in colorectal cancer mortality.” The mechanism behind this possibly restorative impact of exercise remains unclear. 

Heavy Exercise Has Prompt Impacts: 

To illustrate these mechanisms, Devin and the team enlisted people with colorectal cancer. They asked them to complete an intense session of high-intensity interval training (HIIT).

HIIT is a training strategy. It aims to make the individual who does more physical work at a high intensity, by “alternating high-intensity exercise intervals with low-intensity exercise or rest intervals.”  

In the intense session group, the analysts collected blood serum samples from the members at the benchmark. These samples were taken following completing the HIIT session, and 120 minutes after the exercise. However, In the 4-week group, the researchers collected and analyzed blood serum before the mediation and 4-week after.

How Exercise Could Prevent Colon Cancer?

The researchers reported, the “[s]erum obtained immediately following [HIIT], but not 120 minutes post‐[HIIT], significantly reduced colon cancer cell number. 

In particular, the researchers found “noteworthy increase” in specific cytokines — that is, in signaling proteins. These help to balance the body’s immune system and inflammatory reactions. These cytokines were interleukin‐6, interleukin‐8, and the tumor necrosis factor‐alpha.  

The researchers conclude, “The acute effects of [HIIT] and the cytokine flux may be important mediators of reducing colon cancer cell progression.” In addition to this, they also said, “Repetitive exposure to these acute effects may contribute to the relationship between exercise and improved colorectal cancer survival.” 

Devin further remarks on the discoveries, saying, “After an acute bout of HIIT there were specific increases in inflammation immediately after exercise, which is hypothesized to be involved in reducing the number of cancer cells.” 

Moreover, the lead author adds, “This suggests that a physically active lifestyle may be important in tackling human colorectal tumors.”  

“We have shown that exercise may play a role in inhibiting the growth of colon cancer cells.”

However, the strategy used to study colon disease in the lab differs greatly from how these cells develop in the human body. In this way, they have to accomplish more research to investigate the impacts of HIIT on human colorectal tumors.  

Devin says, “We would now like to look at how these changes in growth occur. We would understand the mechanisms by which biomarkers in the blood can impact cell growth.”
