The relationship of exercise and diet on high-density lipoprotein cholesterol levels in women.
The relationship of exercise and diet on high-density lipoprotein (HDL) cholesterol was investigated in 45 long-distance runners (LD), 49 joggers (J), and 47 inactive (I) women. Fasting plasma triglycerides (TG), HDL cholesterol, total cholesterol (TC), and percent body fat (%BF) were measured in women ages 24-58 yr. TG levels were significantly lower in LD compared to I (p less than 0.02). Although TC was not significantly different among groups, HDL-cholesterol was higher in LD (78 mg/dl) compared to J (70 mg/dl) or I (62 mg/dl) (p less than 0.001). Multiple regression analyses indicated that alterations of plasma lipids and lipoprotein levels could not be attributed to intake differences of nutrients. Distance run and %BF were the strongest predictors of HDL-cholesterol in women. LD (23 %BF) were leaner than J (26 %BF) or I (30 %BF); however, when results were adjusted for %BF, significant differences between exercise groups remained for HDL cholesterol.
