We tested the effects of supplementing 2 g/d of docosahexaenoic acid (DHA) (n=24) or placebo (n=28) on blood lipid profiles (ultracentrifugation) in collegiate football athletes (age=20±2 y, ht=73.9±2.6 in, wt=231±41 lb) during preseason training. Blood obtained after an overnight fast three different times: 1) Summer baseline (BASE) before starting supplements; 2) August, pre‐camp (PREC) after 35 d supplementation; and 3) August, post‐camp (POST) after 52 d supplementation. Nutrition assessments completed each time of blood sampling.VAR Placebo (n=28) DHA (n=24) BASE PREC POST BASE PREC POSTTC 142 ± 6 156 * ± 7 148 ± 7 153 ± 6 161 * ± 7 156 ± 7 LDL 78 ± 4 85 * ± 5 85 * ± 5 90 ± 5 95 * ± 5 98 * ± 5 HDL 51 ± 2 55 * ± 3 48 ** ± 2 50 ± 3 53 * ± 3 45 ** ± 2 TG 110 ± 11 146 ± 19 96 * ± 69 115 ± 13 112 ± 21 84 * ± 10 VLDL 12 ± 1 16 ± 2 14 ± 2 12 ± 1 13 ± 2 13 ± 2Table results (adjusted means±SE mg/dL, TC=cholesterol, TG=triglycerides) of 2(supplement)‐by‐3(time) ANCOVA (wt change & race covariates, interactions insignificant) & LSD follow‐ups across time; * = different from BASE, ** =different from BASE & PREC, p <0.05).Reduced HDL‐C and triglycerides with increased LDL‐C during camp might indicate increased cholesterol metabolism for structural repair of damaged tissue. DHA supplementation did not affect the changes in blood lipid profiles of these athletes engaged in heavy physical training. Funding provided by Martek Biosciences Corp., Columbia, MD
