PURPOSE: To determine the effects of two modes of circuit training on blood lipids in college-aged men and women. METHODS: 14 college aged (18-24) subjects were recruited and randomly assigned into either the free-weight training protocol 6 FR or machine training protocol 8 MA. Subjects were asked not to change their dietary intake. Subjects' blood lipid profiles were ascertained using the Cholestech LDX system before and after an 8-week circuit training protocol. Values measured were total cholesterol (TC), HDL, LDL, triglycerides (TRG), and fasting blood glucose (GLU). Both FR and MA completed 1 circuit of 6 exercises the first week, 2 the second, and 3 for the remaining weeks. Pre and post - test comparisons were performed using dependent t-tests in SPSS. RESULTS: Both MA and FR combined showed a statistically significant decrease of 10.43 +/- 15.79mg/dl (p = .014) in TC and no change in other factors. LDL showed a near significant decrease (p = .076) of 6.9 +/-17.01mg/dl. HDL, GLU, and TRG showed no change. For MA, only TC demonstrated a significant change (p = .0385) of 11.25 +/- 15.39mg/dl. For FR, significance was not reached for any measure. Males (combined groups) showed near significance in TRG (p = .056) decreasing by 17.63 +/- 27.38 mg/dl. Women (combined groups) showed significance in TC (p = .014) decreasing 18.17 +/-14.5mg/dl and near significance in LDL (p = .176) at 8.5 +/-12.14mg/dlandTRG(p = .068) at 39.17+/-53.81 mg/dl. Body weight/BMI did not change significantly over the course of the study. CONCLUSIONS: Resistance training with either machines or free-weights appears to be a reasonable method of controlling blood lipids for apparently healthy college-aged women. Further studies should focus on obtaining a larger sample size to determine if the near-significance found in this study were due to a non-significant effect or a small sample size.
