Speed Records investigates the fascinating intersection of sports science and Japanese manga, exploring the reality of human speed versus its exaggerated depiction in popular series. It examines how athletes push the boundaries of velocity in sports like running and swimming, highlighting the physiological constraints and training techniques involved. For example, muscle fiber composition and neurological signals play critical roles in achieving peak speeds. The book also delves into how manga artists visually represent superhuman speed, often defying physical laws. The book uniquely contrasts these two worlds, revealing how cultural fascination with superhuman abilities influences artistic expression.

The investigation progresses systematically, first establishing a scientific foundation of human speed, then analyzing the portrayal of speed in manga, and finally comparing the two to understand their cultural significance. By examining athletic achievements and manga artistry, Speed Records offers a fresh perspective on human potential and imagination, appealing to both sports enthusiasts and manga fans.
