This study is a randomized, parallel-group, double-blind clinical trial. The primary aim is to assess the effectiveness of power-based resistance training, multimodal exercise incorporating non-specific movements, and a control group in improving functionality and body composition in women over 65 years old with pre-sarcopenia. The intervention will take place over 30 weeks, with three training sessions per week in both experimental groups. Assessments will be conducted at two time points: before and after the intervention. Evaluated parameters will include functionality (Timed Up \& Go test (TUG), chair stand test, handgrip strength, and Short Physical Performance Battery (SPPB)) and body composition (body fat percentage, skeletal muscle index (SMI), appendicular skeletal muscle mass (ASM), waist circumference, waist-to-hip ratio, body weight, and body mass index (BMI)).
