Construction and Effect Evaluation of the Low Load Blood Flow Restriction Training Program for Lung Cancer Patients Complicated With Sarcopenia During Chemotherapy

The goal of this clinical trial is to verify the effectiveness and safety of the low load blood flow restriction training program. The intervention effect, tolerance and compliance of low load blood flow restriction training and progressive resistance training on lung cancer patients complicated with sarcopenia during chemotherapy will be compared, in order to provide new ideas for improving or reversing sarcopenia. The main questions it aims to answer are: Can low load blood flow restriction training improve sarcopenia in chemotherapy induced lung cancer patients? Which training method is more effective and tolerable between low load blood flow restriction training and progressive resistance training? Participants will be randomly divided into 3 groups： 1. Routine care group (Control group, CON): The researchers will provide participants with regular exercise and dietary guidance. 2. Low load blood flow restriction group (LL-BFRT): The researchers will provide participants with a low load blood flow restriction training program constructed by our research group. 3. Progressive resistance training group (PRE): The researchers will provide participants with progressive resistance training.
