Background: Having regular exercise has been linked to healthy living. However, exercise is also a stressor. How the body maintain homeostasis in the phase of changing blood chemistry during exercise has been the subject of many discussions. Aim: This study investigated the changes in blood pressure parameters, changes in blood glucose, cortisol, lipids, testosterone and blood free radicals, in exercise-trained young female adults and those living a sedentary lifestyle during a treadmill exercise test. Materials and Methods: Trained and untrained-participants were recruited for this study using predetermined criteria. Basal parameters such as height waist circumference, blood pressure, heart rate, blood glucose, lipid profile as well as antioxidant status were measured prior to and immediately after treadmill exercise test. Results: The results showed a significant (P ≤ 0.05) reduction in plasma level of glutathione (trained 0.040 ± 0.006, untrained 0.088 ± 0.035 ΅mol/ml), catalase (trained 0.909 ± 0.057, untrained 1.079 ± 0.024 mg/ml), malondialdehyde (MDA) (trained 0.062 ± 0.012, untrained 0.088 ± 0.011 nmol/ml), cardiac risk index (trained 1.96 ± 0.19, untrained 5.88 ± 0.33) and testosterone cholesterol ratio (TCR) (trained 0.40 ± 0.02, untrained 0.50 ± 0.04 × 10−2 ) in trained-participants compared to untrained-participants. Post-exercise level of superoxide dismutase (before-trained, 0.116 ± 0.005 after-trained, 0.093 ± 0.014 mg/ml) and MDA (before exercise 0.067 ± 0.007, after exercise 0.062 ± 0.012 nmol/ml) were also significantly reduced in trained-participants compared with the pre-exercise level in the same group unlike what was obtained in untrained-participants. A significant decreased pre-exercise test level of total cholesterol (TC), triglyceride, low density lipoprotein (LDL) and ratio of LDL to high density lipoprotein (HDL) was recorded in trained compared to untrained-participants. Post-exercise test level of LDL, TC/HDL, LDL/HDL ratios were all significantly lowered in trained-participants compared with the untrained-participants. Conclusion: Involvement of young female adults in exercise training promotes body antioxidant response system and also reduced the TCR during treadmill exercise test compared to untrained young female adults living a sedentary lifestyle. Prior involvement in exercise training also promoted healthy blood lipid and lipoprotein profile in this group of participants compared to the untrained-participants. |
