Exercise is an important element in cancer recovery. What exercises can help cancer patients’ physical health? Sports such as soccer and basketball are more strenuous, with high exercise volume and serious physical exertion, which will temporarily weaken the physique and are not suitable for cancer patients. In addition, competitive sports require high physical fitness and flexibility of athletes, which often exceed the physiological limits of cancer patients and should not be participated by cancer patients. There are also some rivalry games, which are fun but often make people restless, and they should not be the first choice for cancer patients to exercise. Cancer patients are suitable for exercises that are less strenuous, with controlled rhythm, more relaxing and can be done gradually, such as walking, jogging, yoga, tai chi and qigong. These exercises are good for the limbs and internal organs, and they are also helpful for mental relaxation and stretching. Regular practice can strengthen the muscles and bones, relax the tendons and blood, enjoy the body and mind, and harmonize the qi and blood. Among many sports, we especially recommend traditional sports in China – qigong and taijiquan to tumor patients. First of all, because taijiquan and Chinese medicine and Chinese traditional culture are in the same lineage, this sport has a very rich and profound connotation. It not only has the basic characteristics of Chinese martial arts “training tendons and bones outside, training a breath of qi inside”, but also requires that the exerciser’s form and spirit are united, and that the holistic concept of “Heaven and Man” is integrated into the exercise. In the process of fighting against the disease, tumor patients experience physical pain and mental torture. Patients mostly show pessimism and despair, which are not conducive to the treatment and recovery of the disease. Taijiquan, through the teaching method of group exercises, easy-to-learn movements and soothing and relaxing music, creates a positive, optimistic and calm atmosphere for tumor patients in the exercise process, and also creates a platform for mutual help and communication between patients and patients and medical workers, so that patients can get rid of the pessimistic mood and build up confidence in treatment, and to a certain extent, divert patients’ attention from the disease itself. The patient’s attention to the disease itself. It is important to know that a positive attitude and a relaxed spirit are necessary to overcome the disease. Secondly, the exercise style of taijiquan can be different from person to person, and the amount of exercise can also be gradual. Most tumor patients can find their own exercise style and amount of exercise in taijiquan practice, as the movement of taijiquan can be dynamic or static, fast or slow, rigid or soft. Once again, the movements of taijiquan are gentle and moderate, spacious and generous. In the process of taijiquan training, patients can achieve significant fitness, which can relax the muscles and blood, and enhance the physical fitness, but also safe and secure, which can avoid the sports injury brought by strenuous exercise to the maximum extent. The practice of taijiquan requires slow and even movements, soft and gentle, static with movement, soft with rigid, natural breathing, so that the metabolism of substances in the body to play a good role in regulation, to promote the digestive function of the gastrointestinal system, so that many patients respond to daily exercise feel comfortable, eat well, sleep well, two bowel movements. Taijiquan is especially about “intention”, which requires a high degree of “mental stillness”, concentration, rhythmic coordination of all parts of the body, so that the upper and lower parts follow each other, the whole body is one, a movement is inactive, a stillness is inactive, and the function of the central nervous system is enhanced. Forgetfulness, brain atrophy, Alzheimer’s disease, etc. also have a preventive effect. One more point should be emphasized here. Although taijiquan exercise has many advantages and is very suitable as a long-term exercise method for tumor patients and helps them achieve a comprehensive physical and mental rehabilitation, it is still strongly recommended that tumor patients seek the advice of a specialist before starting to contact them. The complexity of tumors dictates that cancer patients are all different and often have multiple comorbidities, such as bone metastases and thrombocytopenia. In these cases, even safe exercises such as tai chi may not be suitable for oncology patients. These specific conditions require the judgment of oncologists. With the guidance of oncologists, tumor patients will feel more comfortable to do tai chi exercises.
