This randomized controlled trial aims to investigate the contralateral effects of unilateral training in sedentary women. Specifically, the study compares unilateral isokinetic training and single-leg squat training to determine their effects on strength, proprioception, and muscle thickness in both the trained and untrained lower extremities.

Participants will be randomly assigned to one of the training groups. The intervention will be applied to one lower limb only. Strength, proprioception, and muscle thickness will be assessed before and after the intervention period. The primary objective is to evaluate whether unilateral training induces cross-education effects in the contralateral limb.

The findings of this study may contribute to rehabilitation strategies by clarifying the potential benefits of unilateral exercise programs for improving neuromuscular performance and muscle morphology in sedentary individuals.

Inclusion Criteria:

• female gender,
• no lower extremity problems in the last 6 months,
• not actively participating in sports

Exclusion Criteria:

• history of orthopedic surgery within the last 2 years,
• ongoing lower extremity pain, systemic disease that could prevent exercise,
• a neurological problems.
