NCT07103889

Brief Summary

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.

Interventions

Spartacus TestBEHAVIORAL

The Spartacus test was conducted on a 750 m (75 × 10 m) rectangular course marked with cones at regular intervals to indicate different speeds (from 7 to 18 km/h). Each participant began running at 7 km/h, with speed increasing by 1 km/h every three minutes.During the 3-minute intervals (for each speed stage), participants had 15 seconds to reach the corresponding marker, followed by 15 seconds of rest. Participants had to adjust their running pace to reach the target cone in synchrony with an audio signal. The test ended when a participant failed to reach the next cone within the given time. This test is validated for assessing maximal aerobic capacity (MAS) in obese adolescents. During the Spartacus test, maximal heart rate (HRmax) was recorded using a heart rate monitor (S810; Polar, Kempele, Finland).
