Tai chi training can improve renal and cardiac functions in patients with chronic kidney disease (CKD) and cardiovascular disease (CVD). Chinese researchers randomly divided 21 patients with CKD and CVD into exercise and control groups. The exercise group performed tai chi for 30 minutes, three to five times a week for 12 weeks, while the control group did not. Patients’ renal and cardiac functions and blood lipid parameters were measured at baseline and after 12 weeks. After 12 weeks of tai chi, increases were observed in the estimated glomerular filtration rate (eGFR, a marker of kidney function), left ventricular ejection fraction (LVEF, a marker of heart function) and in serum levels of high density lipoprotein (HDL, ‘good’ cholesterol) level. Decreases were seen in heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and in serum levels of creatinine (Scr), total cholesterol (CH), triglycerides (TG) and low density lipoprotein (LDL, ‘bad’ cholesterol). The change in eGFR correlated negatively with the changes in CH, TG and LDL, and positively with the change in HDL. In addition, the change in SBP correlated positively with the changes in CH, TG and LDL, and negatively with the change in HDL. The authors conclude that tai chi training may improve renal and cardiac functions in CKD and CVD patients via improved regulation of lipid metabolism.
