Article Synopsis
- Individualized jump training programs aimed at optimizing force-velocity profiles have sparked debate regarding their effectiveness, particularly in how they impact maximal average force and shortening velocity.
- Using a musculoskeletal simulation model, the study found that improvements in muscle properties or initial postures did not replicate expected training effects, highlighting the complexity of jump mechanics.
- The authors suggested that skill development plays a crucial role in achieving maximal jump heights, indicating that the effectiveness of these training approaches might not transfer to different tasks, and may not be more beneficial than traditional training methods.
Introduction: It is currently unknown how the central nervous system controls ballistic whole-body movements like vertical jumps. Here we set out to study the time frame of generating muscle activation patterns for maximum-effort jumps from different initial postures.
Methods: We had ten healthy male participants make a slow countermovement from an upright position and initiate a maximal vertical jump as soon as possible following an auditory trigger.
Introduction: Force-velocity profiling has been proposed in the literature as a method to identify the overall mechanical characteristics of lower extremities. A force-velocity profile is obtained by plotting for jumps at different loads the effective work as a function of the average push-off velocity, fitting a straight line to the results, and extrapolating this line to find the theoretical maximum isometric force and unloaded shortening velocity. Here we investigated whether the force-velocity profile and its characteristics can be related to the intrinsic force-velocity relationship.

The instantaneous mechanical power output equals the product of crank angular velocity, crank length, and the tangential pedal force. Radial pedal forces do not contribute to mechanical power.

It has been claimed that observers rely heavily on motion information for their judgment. Here, we studied, for the frontal plane, the added value of motion information over just form information.
