The goal of this clinical trial is to evaluate the acute effects of chicory coffee on metabolism and exercise performance in healthy, moderately active male participants aged 18-25. The main questions it aims to answer are: Does chicory coffee influence glucose, lipid, and energy metabolism after exercise? Does chicory coffee affect physical performance and perceived fatigue levels? Researchers will compare chicory coffee (CC), arabica coffee (AC), and a no-drink control to see if chicory coffee has similar or unique metabolic and performance effects compared to caffeinated coffee or no intervention. Participants will: Consume one of the test beverages (chicory coffee, arabica coffee, or no drink) 45 minutes before performing a shuttle-run test Complete a standardized shuttle-run exercise test Undergo blood sample collection before and after exercise to assess glucose, lactate, LPL, TNF-α, adiponectin, and IL-6 Rate their perceived exertion and record symptoms

This outcome measures blood lactate concentration in mmol/L to evaluate the metabolic response to shuttle run exercise. Capillary blood samples were taken from the fingertip at three time points: before, during, and immediately after exercise.
Timeframe: At baseline (immediately before exercise), mid-exercise, and immediately after exercise
Venous Blood Glucose Level
Timeframe: At baseline (pre-exercise) and within 10 minutes post-exercise
Systolic and diastolic blood pressure
Timeframe: Systolic and diastolic blood pressure measured immediately before and immediately after exercise
Plasma Lipoprotein Lipase (LPL) Level (ng/mL)
Timeframe: At baseline and within 10 minutes post-exercise
Subjective Fatigue Score (Borg Scale)
Timeframe: Immediately after completion of the shuttle run exercise protocol
Tumor Necrosis Factor-alpha (TNF-α)
Timeframe: At baseline and within 10 minutes post-exercise
Adiponectin
Timeframe: At baseline and within 10 minutes post-exercise
Interleukin-6 (IL-6)
Timeframe: At baseline and within 10 minutes post-exercise
