There is no need to talk about the many benefits of exercise, but for cancer patients, some family members are worried about the patient’s body, what work is not allowed to do, in addition to sitting is to lie down, but also not allowed to exercise. Therefore, the obedient cancer patients eat, sleep and do not exercise all day long; eat, sleep and grow meat. But is this really good? It is undeniable that some cancer patients are not suitable for exercise, but in general, the benefits that exercise brings to healthy people can basically be brought to cancer patients as well. Today we look at the American College of Sports Medicine released exclusive exercise guidelines for cancer patients, cancer patients should actually how to exercise. Exercise can directly shrink tumors Recently, published in the “Cell” on the results of this study by Denmark, Sweden, Germany, the United States team. In randomized controlled experiments, this group of experimenters designed different research models of liver cancer, melanoma, and lung cancer. In the study on melanoma, they had the mice exercised for four weeks ahead of time and then underwent subcutaneous implantation of cancer cells, after which the mice continued to be exercised for two weeks. As a result, the mice that consistently exercised in the hamster ball had a 61 percent lower incidence of skin cancer compared to the non-exercising mice in the control group. And in terms of tumor volume, adult female mice decreased by 67 percent and older female mice decreased by 53 percent compared to the non-exercising control group. In addition, the researchers found that the incidence of liver cancer was only 31 percent in the mice that exercised consistently, compared to a 75 percent incidence in the control group. In a model of lung cancer, mice that adhered to exercise had a 58 percent reduction in the size of their lung tumors and a 56 percent reduction in the weight of the tumors compared to the non-exercising controls. For melanoma, exercise slowed the development of malignant lesions. The mice ran roughly 4.1km-6.8km/day. So what is it all about? With such an obvious effect of directly targeting tumors, one can’t help but be curious about the principle. NK cells get all the credit! After much study and comparison, the researchers found that no matter how differently other cells and immune factors were regulated, the response of the NK cells was consistent across a variety of models – the frequency with which they appeared in tumors was nothing compared to that of the non-exercising mice. Seeing this, you might say, well isn’t it true that exercise itself makes NK cells appear more frequently? That’s right, the researchers observed that in mice that didn’t have any tumors, the frequency of NK cells increased in the bone marrow, spleen, and peripheral blood if it also kept exercising like the experimental group! And in mice that already had tumors, adherence to exercise elevated the frequency of NK cells in in the tumors. It’s easy to see that against these multiple tumors in the experiment, exercise had an extremely potent killing effect. And in previous studies, clinical trials for breast cancer and prostate cancer, among others, have also found that exercise improves patient prognosis. Exercise fights 26 types of cancer! A study of 1.43 million people published in JAMA shows that exercise really does protect against cancer! Exercise can reduce the risk of developing 26 types of cancer, 13 of which can be greatly reduced! Including lung cancer, which has the highest mortality rate in China! “Of course, exercise must be moderate, in the end, what kind of amount is more suitable for tumor patients, or need to be integrated into the patient’s specific situation to develop a reasonable plan.” Exclusive exercise recommendations for tumor patients! The American College of Sports Medicine released the “Cancer Survivor Exercise Guidelines” suggests that: for different cancer patients, strength and flexibility training should be adjusted differently, for example: 1, colorectal cancer postoperative fistulas should pay attention to avoid excessive abdominal pressure, so as to avoid the formation of a fistula hernia; 2, postoperative breast cancer patients should pay more attention to the gradual, especially when combined with the upper extremity lymphedema; 3, pelvic tumors combined with the lower extremity postoperative There is insufficient evidence on the safety and benefit of lower limb strength training for those with lower limb lymphedema after pelvic tumor surgery; 4. Attention should be paid to the prevention of incision dehiscence after surgery; 5. Attention should be paid to the amplitude of limb movement for those with central venous catheter. 6. For cancer patients, some special assessments should be made before performing planned exercise workouts, including: 7. Regardless of the length of anticancer treatment, it is recommended that peripheral neuropathy and musculoskeletal lesions be assessed; 8. If there is hormone therapy, it is recommended that fracture risk be assessed; 9. Bone metastases should be assessed to avoid exercise that may cause fractures; 10. Known cardiac patients assess the safety of exercise; 11, morbidly obese people need additional safety assessment; 12, breast cancer patients should be assessed for upper arm/shoulder joints before participating in upper extremity exercise workouts; 13, prostate cancer patients should be assessed for muscular strength and muscular dystrophy; 14, colorectal cancer patients with fistulas should be assessed for prevention of infection and contamination; 15, for gynecological oncology patients, lower extremity assessment is recommended prior to aerobic exercise or strength training Assessment of lymphoedema is recommended before aerobic exercise or strength training. Among the exercise programs for patients with cancer, walking is the first one to be recommended. It is easy and simple to do, and is not limited by time, site and space. Except for bedridden patients, all cancer patients can choose this kind of exercise. Walking can be done at any time regardless of the season. Treading on the grass in spring, pacing the riverside in summer, appreciating the lotus in autumn and walking in the pine forest in winter are all interesting and refreshing. Walking is not limited by space, no matter in the countryside, strolling slowly on the field path, or in the city boulevard, that wide space, green environment, fresh air, will make people refreshed, relaxed and happy. Cancer patients can also choose jogging, walking, playing tai chi, unarmed gymnastics, swimming, qigong and cycling and other sports. 1, exercise intensity Cancer patients should not participate in strenuous exercise, in principle, they should choose low intensity, longer duration, slightly sweaty after exercise, to be gradual and persistent. Exercise intensity is more suitable for cancer patients with a heart rate range of 50% to 70% of the maximum heart rate, i.e., (220-age) × 50-70%. For example, the heart rate range of a 60-year-old patient during exercise is (220-60) × 50-70% = 80-112 beats/min. Before and after exercise, 5-10 minutes of preparatory activities and relaxation activities should be carried out to adapt the heart rate changes to the changes in exercise intensity and avoid discomfort after exercise. It is not suitable to participate in too intense exercise, so as to avoid excessive fatigue and reduce autoimmune function. 2, the amount of exercise Patients start exercise can include pre-exercise preparatory activities and the recovery and finishing time after exercise. After reaching the intensity of exercise, patients should keep exercising for 30 minutes. The best time of the day for cancer patients to exercise is usually in the morning or afternoon, and it is not suitable for them to exercise after a full meal or when they are hungry. To avoid discomfort. The amount of exercise should be small at the beginning, and the exercise time should not be too long, 15-20 minutes each time, and the amount of exercise should be increased gradually to 30-40 minutes each time according to the condition and physical strength. 3, the frequency of exercise at least 3 ~ 4 times a week, every other day. For those who have strong physique and are not fatigued after exercise, they can insist on exercising every day. 4. Exercise environment and weather The natural environment is an important factor affecting the effect of exercise. It is advisable to exercise in parks, forests, meadows, fields, waterfronts and other places where the air is fresh and the environment is quiet, and it is best for cancer patients to exercise in forests. Attention should be paid to seasonal changes; the amount of exercise should be appropriately reduced in case of weather changes such as too cold or too hot season, windy and rainy weather. Exercise is suitable for people 1. It is suitable for all kinds of cancer patients except bedridden patients. 2.Patients with stabilized condition after operation. 3. Patients with stable condition after radiotherapy and chemotherapy. 4.Patients with no sequelae after tumor treatment and no metastatic lesions after diagnosis can participate in various fitness exercises suitable for their physique and people of the same age. 5.Patients with various comorbidities should choose appropriate programs according to their own conditions. Exercise contraindication crowd 1, postoperative. 2.Combined with various acute infections. 3.Elevated body temperature, relapse. 4, certain parts of the bleeding tendency, should stop exercise to avoid accidents. 5, there are obvious malignant patients can not tolerate exercise. Warm tips: (1) Cancer survivors with low immunity should avoid exercising in public stadiums before their blood cell counts return to normal levels. (2) Cancer survivors who have received radiation therapy should avoid long-term exercise in swimming pools containing chlorinated disinfectants. (3) Do not participate in overly intense exercise to avoid over-fatigue and lowering of autoimmune function. (4) Keep breathing smoothly and stop exercising immediately if you feel unwell. (5) If there is a rise in body temperature, a relapse of the disease, or a tendency to bleed from certain parts of the body, exercise should be stopped to avoid accidents.
