To examine the effects two types of single - session aerobic training on LDL-C, HDL-C, and subcutaneous fat, twenty college non - athlete males were selected non-randomly. Their average age, weight and height were (21.8:t2.29) years, (64.65:t5.63) kilograms, and (174:t5.49) centimeters for group one with Interval Running Training (IRT), and (23.2:t 1.32) years, (64.4:t 10.29) kilograms, (179.8:t5.39) centimeters for group two with circuit weight training (CWT), respectively. The subjects of group one were engaged in a training program including
one session of aerobic IRT for 40 mins, (walking 1 min.) with 60-80 percent of maximal heart rate (MHR), ending with 10 mins of cool down. The second group was involved in one session of aerobic CWT using 10 stations. It lasted 40 mins started with 10 mins of warm - up, 20 mins for CWT with 60-80 percent of MHR ending with 10 mins of cool - down. Statistical analysis with (P<0.05) reveals that: a) one session of IRT had no significant effect on the amount of HDL-C, LDL-C, and subcutaneous fat and b) one session of CWT had a significant effect on the amount of HDL-C but not on the amount of LDL-C and subcutaneous fat.
Conclusion: Experiments reveal that the level of plasma fats is affected more by a single session of aerobic circuit weight training (CWT) as compared to a single session of aerobic Interval Running Training (IRT).
