Abstract:
AIMRats cardiovascular expression of CGRPmRNA surveyed after an eight-week swimming training, and molecular mechanism of exercise-induced adaptation were studied.
METHODS24 purebred male SD rats were divided randomly into three groups (n = 8): control (CR), exhaust (ER), train (TR). After swimming training left ventricular muscle and main artery arch were extracted, we inspected the expression of CGRPmRNA by RT-PCR.
RESULTS(1) Comparing with the control group, once exhausting exercise had no significant effect on cardiovascular expression of CGRPmRNA. (2) Comparing with the control group, long-term aerobic swimming training upregulated significantly cardiac expression of CGRPmRNA.
CONCLUSIONLong-term aerobic training induced benign cardiac adaptation in molecular level. Long-term aerobic swimming training had no significant effect on vascular expression of CGRPmRNA.
