Abstract
The purpose of this research was to measure nutrient intake, body fat, [estimated from seven skinfolds: chest, axilla, triceps, subscapular, abdominal, suprailiac, and thigh (Jackson and Pollock, 1985)], total cholesterol (TC), HDL-cholesterol (HDL-C), HDL2-C, and HDL3-C of 19 male and 8 female bodybuilders competing in the National Physique Committee's USA Bodybuilding Championships (Raleigh, NC, April 1988). Casual blood samples and anthropometric data were collected 18 hours prior to competition, whereas 7-day diet records were completed 1 week prior to competition. Only 11 males and 2 females provided blood samples. Competitors were not tested for steroid use. These data are unique because the measurements were collected on site at the competition. Data are presented as means and standard deviations. Estimated body fat for males (6.0 +/− 1.8%) and females (9.8 +/− 1.5%) was quite low. Blood lipids (mg%) for males (TC = 187 +/− 11, HDL-C = 37 +/− 6, HDL2-C = 13 +/− 4, and HDL3-C = 24 +/− 4) were not indicative of increased coronary heart disease (CHD) risk. Data for the 2 females (TC = 190, 205; HDL-C = 56, 56; HDL2-C = 22, 8; and HDL3-C = 34, 48) could only be evaluated on an individual basis. Body fat was significantly correlated with HDL-C (r = 0.63; p = 0.04) and HDL3-C (r = 0.65; p = 0.03), but not TC nor HDL2-C. Of the dietary variables, only saturated fat was significantly correlated with HDL2-C (r = 0.60; p = 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
