2021 CSCO Guidelines Meeting Cancer Nutrition Treatment Guidelines

Jul 01, 2021

The combination of nutrition and exercise is considered the best way to maintain muscle function.

The study of Markofski et al. concluded that "healthy elderly supplemented with essential amino acids (EAA) + aerobic exercise increased leg muscle strength after 6 months." The study grouped healthy elderly people into groups and carried out nutritional intervention (EAA15g/d, 24 weeks in total) and exercise intervention (aerobic exercise three times a week for 24 weeks in total). The results showed that both the exercise group and the exercise+EAA group could increase Maximum oxygen uptake and pace, increase muscle protein synthesis, increase leg muscle strength; there is no difference in body weight, lean body mass, and leg muscle mass in each group.

The combination of nutrition and exercise can effectively increase muscle mass and muscle strength

The results of RCT conducted by Kim HK et al. on elderly women with sarcopenia in the community in Japan showed that exercise (60 minutes each time, 2 times a week for 3 months) combined with AAS (AAS: Leucine-rich essential amino acid complex) (3g/time*BID for 3 months) supplementation can improve the muscle mass and muscle strength of elderly women with sarcopenia in the community.

Sports exercise precautions

Exercise-related injuries should be avoided during exercise, especially in patients with comorbidities, immunocompromised patients, severe fatigue after treatment, skin injuries, peripheral neuropathy and ataxia.

Exercise type and method

Common types of exercise include aerobic exercise and resistance exercise. In order to maintain muscle mass and muscle strength, it is recommended to combine aerobic exercise and resistance exercise, and each exercise intensity and exercise time should follow the principle of gradual progress.

Exercise modes are divided into low intensity, medium intensity and high intensity. Moderate-intensity exercise refers to the ability to speak but not to sing during exercise, such as: flat bike, baseball, volleyball, brisk walking, etc.; high-intensity exercise refers to only speaking simple words during exercise, without stopping to breathe, such as aerobic Dancing, fast cycling, skipping rope, race walking, jogging, swimming, etc.

Different exercise strategies at different stages of tumor treatment

For patients in the initial and advanced stages, nutritional therapy should be appropriately strengthened, exercise intensity should be reduced, and appropriate exercise methods and exercise amounts should be selected according to their physical strength; for patients in the recovery period and disease-free survival period, reasonable diet and appropriate exercise exercise are required. To help improve the quality of life and survival of patients, refer to the exercise mode of healthy people. The guidelines for nutrition and exercise during and after cancer treatment issued by the American Cancer Society (ACS) cover weight management, exercise exercise, dietary patterns of whole grains of vegetables and fruits, and alcohol restriction. A number of studies have proved that strictly following this guideline can significantly reduce cancer mortality and improve the quality of life.
