biomechanical efficiency

Syllable breakdown

Dictionary meaning

the degree to which an athlete's movement technique minimises energy expenditure relative to the mechanical output produced, measured by comparing the metabolic cost of a movement to its mechanical work output; high biomechanical efficiency means that an athlete converts more of the energy their muscles consume into useful movement, reducing fatigue and allowing them to sustain higher performance levels for longer; biomechanical efficiency is analysed using motion capture systems, force plates, and metabolic measurement equipment, and is a key target of technique coaching, equipment design, and injury prevention programmes across running, cycling, swimming, and field sports
