Hardaliye Group consumed 250 ml/day of hardaliye (grape juice) for 28 days. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in total antioxidant capacity | Measurement of serum level of total antioxidant capacity (μmol Trolox eq/L). | 28 days |
| Change in total oxidation status | Measurement of serum level of total oxidation status (μmol H2O2 eq/L). | 28 days |
| Change in oxidative stress index | (Serum level of total oxidation status/serum level of total antioxidant capacity) × 100 | 28 days |
| Change in lipid parameters | Measurement of serum levels total cholesterol (mg/dl), HDL-cholesterol (mg/dl), LDL-cholesterol (mg/dl) and triglycerides (mg/dl). | 28 days |
| Change in blood pressure | Measurement of systolic (mm Hg) and diastolic blood pressure (mm Hg) | 28 days |
| Measure | Description | Time Frame |
|---|---|---|
| Change in perceived exercise-induced pain | Perceived exercise-induced pain was determined using the 100-mm Visual Analog Scale. 100-mm Visual Analog Scale scores range from 0 (no pain) to 100 (most severe pain). A higher score indicates a higher perceived pain level. | 28 days |
