Effect of Acute Exercise on Biochemical Parameters in Normal-Weight and Overweight/Obese Adolescent.

The goal of this interventional clinical trial is to compare the acute physiological and biochemical responses to maximal physical exercise (Spartacus test). in two groups of adolescent girls: in normal-weight and overweight/obese adolescent. The main question it aims to answer: * Does Spartacus test significantly alter glucose metabolism and lipid profile in normal-weight and overweight/obese adolescent? * How do inflammatory markers such as C-Reactive Protein \[CRP\], Erythrocyte Sedimentation Rate \[ESR\], respond immediately after and 30 minutes following maximal effort? * Are there significant changes in liver enzymes (Aspartate Aminotransferase \[AST\], Alanine Aminotransferase \[ALT\]), muscle damage indicators (creatine kinase \[CK\], Lactate Dehydrogenase \[LDH\]), and electrolyte balance post-exercise? Participants will undergo a baseline blood draw before performing the Spartacus test , a progressive maximal exercise test. Blood samples will then be collected immediately after the test and again 30 minutes post-exercise to evaluate changes in: Glucose metabolism (fasting glucose), Lipid profile (total cholesterol, High-Density Lipoprotein \[HDL\], Low-Density Lipoprotein \[LDL\], triglycerides), Liver and muscle enzymes (Aspartate Aminotransferase \[AST\], Alanine Aminotransferase \[ALT\], Creatine kinase \[CK\], Lactate Dehydrogenase \[LDH\]), Renal function markers (creatinine, urea), Inflammatory markers (C-Reactive Protein \[CRP\], Erythrocyte Sedimentation Rate \[ESR\]), Hematological profile (complete blood count: White Blood Cells \[WBC\], Red Blood Cells \[RBC\], Hemoglobin \[Hb\], Hematocrit \[Hct\], platelets), Electrolytes (sodium, potassium, chloride), Uric acid, calcium, phosphorus, magnesium, iron.
