scientific knowledge, it is evident that maximal relative strength, rate of force development, and peak power-generating capacity are the most important physical attributes to increase sprint performance. 6 A widely used approach to develop power output is called “optimal load” training, which consists of

can derive other biomechanical metrics describing the jump performance, such as force, power, velocity, and center-of-mass position. Force data derived from inertial sensors have been shown to agree well with simultaneously recorded force plate data. 16 However, although jump heights derived from

prescribed levels of training intensity. From a biophysical perspective, average mechanical power output (hereafter called “power output”) over one or more stroke cycles constitutes a suitable measure to control rowers’ compliance with training intensity as it is (1) strongly related to a rower’s rate of

Maximum dynamic strength assessments, also called 1-repetition maximum (1RM) tests, are widely used by coaches and researchers to both evaluate neuromuscular performance and determine training loads. 1 The prescription of strength–power training is usually based on different percentages of 1RM

Pacing refers to an athlete’s distribution of work or energy across an event. 1 , 2 Athletes vary their physical output (ie, mechanical power output) to accommodate physiological or psychological constraints, for strategic racing purposes, or due to changing environmental factors. 2 , 3

The peripheral muscle dysfunction of the lower limbs observed in older men with COPD is characterized by a reduction in the maximum muscle strength and

Mechanical power ( F · v ) is considered a determinant of athleticism. 1 In isolated joint actions, the force–velocity relationship is a hyperbolic curve, with power maximized at approximately 15% to 30% of absolute contractile force. 2 , 3 However, during dynamic multisegmental movements, a

Measurement of Aerobic Power—Why is it Important? Maximal aerobic power ( V ˙ O 2 max ) is one of the 2 main constituents of aerobic capacity—the other one being aerobic endurance (percentage of V ˙ O 2 max that can be maintained for given distances or durations). Aerobic endurance is difficult
