细胞免疫系统中,自然杀伤(NK)细胞最易受到短期和长期体育活动的影响。本研究旨在调查运动锻炼对已治疗的乳腺癌病人自然杀伤细胞的细胞毒力(NKCA)的影响。 受试者为16名女性乳腺癌病人,年龄35～72岁。她们4年前被确诊为乳腺癌,接受手术、化疗或放疗,平均3.0±1.2年。目前无一病人接受化疗或放疗。试验前病人完成下面测试:(1)活动平板症状限制性运动测试,(2)6min步行测试,(3)用Kin-Com等速测力器测试下肢伸肌肌力,(4)测定静脉
In the cellular immune system, natural killer (NK) cells are most susceptible to short-term and long-term physical activity. The purpose of this study was to investigate the effect of exercise training on natural killer cell cytotoxicity (NKCA) in treated breast cancer patients. The subjects were 16 women with breast cancer and were 35 to 72 years old. They were diagnosed with breast cancer four years ago. They received surgery, chemotherapy, or radiotherapy for an average of 3.0±1.2 years. At present, there is no patient receiving chemotherapy or radiotherapy. Before the trial, the patient completed the following tests: (1) exercise-limited symptom-limited exercise test, (2) 6-minute walk test, (3) test the lower extremity extensor muscle strength with a Kin-Com isokinetic force device, and (4) determine the vein
