Interventions
OTHER

Resistance Training (High-Intensity)

Leg press exercise performed at 70-80% of 1RM, structured as 4 sets × 10 repetitions, with controlled tempo and standardized rest intervals (2 minutes).

OTHER

Resistance Training (Low-Intensity)

Leg press exercise performed at 20-30% of 1RM, structured as 4 sets (30/15/15/15 repetitions), with controlled tempo and shorter rest intervals (1 minute).

OTHER

Normobaric Hypoxia

Environmental intervention simulating an altitude of approximately 3500 meters (\~13.5% FiO₂) using a normobaric hypoxic chamber.

OTHER

Normoxia

Training under normal atmospheric oxygen conditions (\~20.9% FiO₂).
