Inspired by the generalized motor program (GMP) theory, this study presents a symbolic motion structure representation (SMSR) algorithm that identifies a basic spatial-temporal structure of a human motion. The algorithm resolves each joint angle-time trajectory of a multi-joint motion into a sequence of elemental motion segments and labels each motion segment with a symbol representing its shap...

The purpose of this study was to examine the influence of two different bar diameters on neuromuscular activation and strength. The bar diameters used reflected a standard Olympic bar (28 mm (1.1 inch); THIN) and a larger fat bar (51 mm [2 inch]; THICK). Eighteen healthy men (age 25.06 1 years) were assessed for their maximal voluntary contraction (MVC) during a unilateral isometric bench press...

Inertial measurement units (IMUs) increasingly function as a basic component of wearable sensor network (WSN). The IMU-based joint angle estimation (JAE) is typical usage IMUs for WSN, with extensive applications. However, the issue that move respect to their original placement during JAE still research gap and limits robustness deploying technique in real-world application scenarios. In this s...

We used a particular computational approach, the uncontrolled manifold hypothesis, to investigate joint angle covariation patterns during whole-body actions performed by standing persons. We hypothesized that two kinematic synergies accounted for the leg/trunk joint covariation across cycles during a rhythmic whole-body motion to stabilize two performance variables, the trunk orientation in the...
