Power Definition & Mechanical Formula
Power (P) is the rate at which mechanical work is performed per unit of time (P = W / t), or the product of torque and angular velocity (P = τ × ω). Expressed in Watts (W), isokinetic power measures how rapidly muscle work can be delivered during fast movement speeds (e.g. 240°/s to 300°/s).
Power (Watts, W) = Torque (τ) × Angular Velocity (ω)
Time to Peak Torque & Explosive Recruitment
Time to Peak Torque (TPT)measures the duration (in milliseconds) from initial movement onset until maximum torque is attained. TPT reflects explosive type-II muscle fiber recruitment, spinal motor neuron firing rate, and Rate of Torque Development (RTD). Elite sprinters and jump athletes demonstrate shorter TPT values (typically <150–200 ms).
