| Abstract: | The purpose of this study was to compare training modalities in terms of selected coronary heart disease indices. Fifty-seven male volunteers served as subjects. Nineteen were endurance trained subjects, nineteen were strength trained weightlifters and the other nineteen subjects were age-matched sedentary controls. The blood lipids were measured from 2 blood samples collected 7 days apart following a 12-hour fast and 48 hours after the last bout of exercise. Hydrostatic weighing was used to determine percent body fat. The VO2 max was determined utilizing a treadmill protocol. A correlation matrix was developed to identify the degree and direction of relationships among the investigated variables. The data revealed that all the investigated variables except PWV were intercorrelatd. A one-way analysis of variance was used to analyze the pulse wave velocity among groups. A factor analysis was applied to select the representative variables from all the variables for a multivariate analysis of variance (MANOVA). The variables of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), %BF and VO2 max were selected from factor analysis and were analyzed by MANOVA. A simultaneous confidence interval post hoc procedure was used to determine the differences among the three different groups. The following conclusions are warranted: 1. Body composition, VO2 max and blood lipid profile were significantly intercorrelated. 2. Individuals who engaged in training modalities of endurance exercise, weightlifting and nonexercise did not differ in terms of PWV. 3. Endurance runners, weightlifters and sedentary controls did not differ in their LDL-C concentration. 4. Endurance runners had a significantly higher average HDL-C concentration than sedentary individuals. Weightlifters did not differ from runners or sedentary individuals in terms of HDL-C concentrations. 5. The %BF of endurance subjects was significantly lower than sedentary individuals. The %BF of weightlifters was not different from that of runners or sedentary subjects. |
