Capturing the Essence of Energy for Exercise
Research: Exploring the sources of power at the molecular level.
Exercise professionals devote fervent attention to learning the intricate mechanisms of muscle actions and understanding how the contractile proteins (such as myosin and actin) create force to do an array of exercises. But the source of that force—the biochemistry of energy—often remains a mystery. This column will discuss recent explanations that help demystify the processes happening at the molecular level, where cells channel energy from food into the work accomplished by exercise.
