A detailed anatomical illustration showcasing the mechanics of eccentric and concentric muscle contractions. In the foreground, a stylized human figure performing a bicep curl, with the muscle fibers highlighted to reveal the lengthening and shortening during the eccentric and concentric phases. The middle ground features a technical diagram with labeled arrows and annotations, explaining the biomechanical differences between the two types of muscle work. The background is a clean, minimalist space with subtle grid lines, conveying a sense of scientific analysis and precision. The lighting is soft and directional, casting subtle shadows to accentuate the muscular details. The overall mood is one of educational clarity, highlighting the key concepts in a visually engaging manner.
