The Effects of Rope Training on Lymphocyte ABCA1 Expression, Plasma ApoA-I and HDL-c in Boy Adolescents

Abstract

Background: Early obesity and its transfer to the adulthood, increases likelihood incidence of coronary artery disease (CAD). ATP-binding cassette transporter (ABCA1) as a member of the ABC transporters family plays a crucial role in reverse cholesterol transport and CAD prevention. Objective: The current study aimed to investigate ABCA1 expression in lymphocytes, plasma apolipoprotein A-I and HDL-C in response to eight-week interval endurance rope training in overweight and obese boy adolescents. Patients and Methods: Thirty students (17.3 1.1yr, 85.73 11.68 kg and 28.41 2.36 kg / m) volunteered and were randomly assigned into training (n = 15) and control (n = 15) groups. Exercise protocol was interval endurance rope training (8 wk, 4 d/wk and 40 min/d). Cell hemolysis and sensitive Elisa method was used for Lymphocyte ABAC1 protein expression.t-test was employed. Results: The independent-samples T-Test results showed that after 8 weeks IERT, the levels of lymphocyte ABCA1 expression(P = 0/001) and VO2max(P = 0/001) significantly increased and plasma levels of TG(P = 0.017), TC(P = 0.001), LDL-c/HDL-c(P = 0.026),TC/HDL-c(P = 0.002) and measures of BF%(P = 0/015)and BMI(P = 0.042) as anthropometric indicators significantly decreased. Changes of other variables such as increase in ApoA-I, HDL-c and decrease in LDL-c, body weight, were not significant. Conclusions: The findings of this study proved that eight-week interval endurance rope training can have positive effects on lymphocyte ABCA1 protein expression (as gatekeeper of reverse cholesterol process) and lipid profiles among overweight and obese boy adolescents.
