Research seeks optimal exercise intensity for cancer patients, including elite athletes

At Memorial Sloan Kettering Cancer Center, researchers led by Sara Hassing Johansen are investigating the physiological impact of exercise on people receiving cancer therapy. While existing recommendations are based on moderately active patients, little is known about those who train at high levels before diagnosis. The studies aim to determine safe training volumes, how intensity should be adjusted for treatment side effects, and whether exercise can help patients tolerate full treatment doses.

Findings will inform individualized advice, emphasizing that any activity— from hallway walks to treadmill intervals— can counteract loss of fitness. Ultimately, the work seeks to move from the general statement that exercise helps to pinpoint the most effective programs for each individual.
