RT Journal Article SR Electronic T1 Study of lipid profile of trained and untrained population JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP i6 OP i6 DO 10.1136/bjsm.2010.078725.18 VO 44 IS Suppl 1 A1 Sunil Purohit A1 Rabindra Kumar A1 Kunjama Sebastian A1 Simarjeet Singh YR 2010 UL http://bjsm.bmj.com/content/44/Suppl_1/i6.2.abstract AB The aim of the present study was to determine the effect of competitive training on serum lipid profile. Three groups of subjects were studied, that is, walker (n = 11), boxers (n = 11) and sedentary subjects (n = 11). Triglycerides, cholesterol/HDL cholesterol ratio (C/H ratio), total cholesterol and its fractions – HDL, LDL and VLDL cholesterols were determined in serum by an enzymatic/colorimetric method. Result shows that sedentary subjects have least favourable concentrations of lipid profile. But a statistically significant difference of C/H ratio, LDL and HDL-cholesterol was found in walkers as compared with other groups. On the basis of the results we can conclude that competitive sport training has beneficial effect on serum lipid profile and endurance-directed activity has more favourable effects on lipid parameters.
