Countermovement jump performance assessment using a wearable 3D inertial measurement unit.
The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of...
متن کاملCountermovement Jump Performance
Post-activation potentiation (PAP) following a bout of high-intensity exercise of short duration is known to produce both a fatigued and a potentiated state. There has been much research in the effectiveness of various PAP protocols, yet the type of dynamic muscle action utilized has seldom been investigated. Therefore, the present study aimed to assess whether an accentuated eccentric load (AE...
متن کاملAn Inertial Measurement Unit for User Interfaces
We have developed a compact, six degree-of-freedom inertial measurement unit for user interfaces. The system uses three axes each of gyroscopes and accelerometers for full 6-axis inertial sensing, and transmits data wirelessly to an external basestation, providing full state updates at 75 Hz. Circuitry for proximity sensing and ID transmission through capacitive coupling was also constructed. W...
متن کاملInertial Measurement Unit Simulator
During the last few years microminiaturized inertial sensors were introduced in many applications. Their small size, low power consumption, rugged construction open doors to many areas of implementation. The main drawback of these sensors is the influence of different type of errors, leading to an unavoidable wrong position and orientation estimation. In the paper a simulator of Inertial Measur...
متن کاملIs the effect of a countermovement on jump height due to active state development?
PURPOSE To investigate whether the difference in jump height between countermovement jumps (CMJ) and squat jumps (SJ) could be explained by a difference in active state during propulsion. METHODS Simulations were performed with a model of the human musculoskeletal system comprising four body segments and six muscles. The model's only input was STIM, the stimulation of muscles, which could be ...
