WebApr 12, 2024 · The concentric muscle contraction, or concentric phase, is described by the cross-bridge (sliding filament) theory. According to this theory, the myosin heads cyclically attach to specific sites on actin filaments, forming cross-bridges. Each cross-bridging cycle consumes one molecule of adenosine triphosphate, or ATP (energy).
