Neuromuscular physiology

How fast force rises at the start of a contraction

In neuromuscular physiology, the rate of force development is how quickly muscle force rises at the onset of a contraction, the slope of the force-versus-time curve, which determines performance in actions too brief to reach maximal force, such as sprinting, jumping, and recovering balance. Aagaard and colleagues' 2002 study showed that resistance training raises early-phase RFD alongside greater neural drive, and Maffiuletti and colleagues' 2016 review set out its physiological determinants and how to measure it reliably. The referent is the time course of force rise rather than its peak, measured in newtons per second over defined early intervals, and it is distinct from maximal strength.[1][2]

Unit
The slope of force over time, in newtons (or newton-metres) per second
Recovery means
Rate of force development is blunted by neuromuscular fatigue and recovers as neural drive and contractile function are restored
Measured by
Taken as the slope of the force-time curve over early windows (e.g., 0–50, 0–100, 0–200 ms) in explosive isometric or dynamic contractions
