Abstract
The purpose of the present study was to determine the acute effects of strenuous exercise on the following blood constituents: total cholesterol (TC) 1 triglycerides (TG) 1 high density lipoproteins (HDL-C) 1 and low density lipoproteins (LDL-C). A single case study was performed during a 20 day testing period. Two century bicycle rides ( 100 miles) were used as the strenuous exercise bouts. Blood samples were drawn each day and immediately after each 100 mile ride. A pre-set exercise and diet regimen were followed every day of the 20 day procedure. A t-test upon TC 1 TG 1 HDL-C 1 and LDL-C was done to determine the statistical significance between two 100 mile cycling rides and the training days. The change upon TC was an increase of 11.1mg/dl and the change upon TG was an increase of 66.8mg/dl. The t-tests upon both of these variables were found to be significant at the <0.05 level. The change upon HDL-C was an increase of 3.2mg/dl but a ttest showed no statistical significance at the <0.05 level. The change upon LDL-C was a decrease of 2.6mg/dl but a t-test showed no statistical significance at the <0.05 level. Total cholesterol to HDL-C ratio (TC/HDL-C) did not change and a t-test showed no statistical significance at the <0.05 level. The ratio stayed at 2.5 for the duration of the study period. It was determined that an acute bout of exercise significantly changed TC and TG levels. Total cholesterol mean values changed from 106.4mg/dl ± 1.11 to 117.5mg/dl ± 3. 53. Mean TG values changed from 66. 2mg/dl ± 4. 08 to 113mg/dl ± 16.97. The acute bout of exercise did not significantly change HDL-C or LDL-C. possibilities are discussed.
