strength and maximal isometric force production. 4 , 5 In addition to demonstrating the importance of a high maximal force capacity (ie, a high maximal force production), the ability to rapidly produce high levels of force is paramount during athletic tasks, as there is a limited duration for the

Sport scientists and applied practitioners regularly monitor and prescribe training programs based on assessments of force production tests. Two examples of such tests are the isometric midthigh pull (IMTP) and the isometric squat tests. 1 , 2 Both require subjects to stand on a force plate and

swimming velocity, it is demonstrated that, for maximal swimming velocity, higher efficiency is obtained lowering the speed-specific drag. 3 Theoretically, intracyclic velocity variations are the result of intracyclic variations of the resultant horizontal force ( dF ) applied by the swimmer to the water

Optimizing muscle power and rapid force production is important for peak performance in several sports. 1 , 2 Weightlifting movements such as the power clean (PC) closely mirror many unloaded athletic movements as they are ballistic and biomechanically similar to jumping, sprinting, and change of

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 be sustained decreases as a hyperbolic function of increasing power, speed, tension, or force (eg, power illustrated in Figure  1 ). 6 Consequently, performance and the point of exhaustion are highly predictable. When work data are plotted against time, it may be observed that power output falls

skeleton-specific intensified training, focused on developing these physical characteristics, can successfully progress a novice skeleton athlete into a Winter Olympian. 6 The generation of muscular power is, however, a product of contraction force and velocity, and it is possible for different athletes to

A key physical determinant of many sports is the ability to express force at a range of movement velocities. 1 , 2 In sprinting acceleration, assessing the component of ground-reaction force applied in the direction of the sprint (ie, horizontal force [ F h ]) can help further our understanding of

The Reactive Strength Index (RSI) accounts for the duration of force production to achieve a given jump height by dividing jump height by ground-contact time. 1 RSI is a more easily obtainable metric than force-platform-derived variables, and it provides greater insight into neuromuscular and
