چکیده
The study focuses on the design and manufacture of an Eccentric Smith Machine, incorporating specialized mechanical components for enhanced athletic benefits, minimizing injuries, and promoting hypertrophy. The Eccentric Smith Machine comprises three main parts: A stable Smith machine adapted for electrical motor shocks, an electrical component with a panel and motor, and a transmission system using four pulleys and two cables. The mechanical design facilitates acute and smooth bar movement, ensuring safety and ease of use for athletes of varying heights and strengths. The Eccentric Smith Machine demonstrates resilience to electrical motor power, simplicity in usage, and safety advantages. Its adaptability makes it accessible to athletes with diverse physical characteristics, providing a tool for effective and safe resistance training. The designed device has the potential to enhance physical fitness, particularly muscle hypertrophy. It stands as a viable option for athletes, offering a reduced risk of injuries during workouts. The Eccentric Smith Machine presents itself as an alternative for those recovering from minor injuries, contributing to overall workout safety.
