Watch nowExercise has long been linked to better immune health, but much less is known about what happens inside individual immune cells as fitness increases. A new study examined how cardiorespiratory fitness is linked to energy use and signaling in cytotoxic T cells, immune cells that help destroy infected or abnormal cells. The study included 43 healthy adults aged 20 to 40. Each participant completed a demanding cycling test to estimate their aerobic fitness, meaning how well the body delivers and uses oxygen during hard exercise. Using resting blood samples, researchers analyzed cytotoxic T cells ... exercise immune system
Read moreChemotherapy often causes problems with memory, concentration, and mental fatigue, but clinics still do not have a standard way to treat these symptoms. In a large new trial, researchers tested whether a simple at-home exercise plan could help protect cognitive function during treatment and support healthy immune activity among cancer patients. The phase 3 trial included 687 adults who were starting chemotherapy at 20 oncology clinics across the United States. Participants were randomly assigned to usual care or to EXCAP, a six-week home program that combined walking with resistance-band exer... cancer exercise

Watch nowPeople who regularly engage in high-intensity aerobic exercise have nearly half as many upper respiratory infections as sedentary people, a 2010 study found. Those who engage in high-intensity aerobic exercise also experience fewer and less severe upper respiratory symptoms than those who engage in lower-intensity exercise. Researchers tracked the number and severity of respiratory infections during the fall and winter of a single year among more than 1,000 adults. The participants, who were between the ages of 18 and 85 years, provided information about the frequency and intensity of their a... exercise immune system
Read moreEffect of aerobic exercise on cancer in mice: > Training mice regularly on a wheel (the mouse version of a treadmill) decreased the growth of multiple types of tumors, including skin, liver, and lung cancers. Furthermore, mice that exercised regularly had a smaller chance of developing cancer in the first place. The beneficial effects of running went beyond tumor formation and growth, extending to cancer-associated weight loss, a process termed cachexia that is seen in cancer patients. Mice that exercised regularly showed no signs of cancer-associated weight loss in the researchers' lung ca... exercise cancer immune system aerobic il-6

Watch nowSome of the mechanisms by which exercise protects against cancer and sensitizes cancer cells to death include: •Increased blood flow, shear stress on the vascular bed, temperature increases, sympathetic activation and endocrine (release of catecholamines and exercise hormones, myokine secretion) •Increased tumor perfusion, oxygen delivery, •Metabolic stress within the tumor, cellular damage, and reactive oxygen species production. These acute changes are able to elicit signaling pathways that prevent metastasis. •Improved immune function, reduced systemic inflammation, and improved meta... exercise cancer
