Aging and Muscle Fatigability in the Upper Extremity [PDF]

, 2017
Aging is accompanied by reductions in strength and contraction velocity, and increased fatigability of limb muscles during high-velocity dynamic contractions.

Canonical decomposition of a tetrablock contraction and operator model

, 2016
A triple of commuting operators for which the closed tetrablock $\overline{\mathbb E}$ is a spectral set is called a tetrablock contraction or an $\mathbb E$-contraction. The set $\mathbb E$ is defined as \[ \mathbb E = \{ (x_1,x_2,x_3)\in\mathbb C^3\,:\,

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Tissue‐specific and spatially dependent metabolic signatures perturbed by injury in male and female mice

Arthritis &Rheumatology, Accepted Article.
Objective Osteoarthritis—the leading cause of disability worldwide—disproportionately affects females, yet sex remains an overlooked determinant. This disparity stems from sex‐specific differences in injury susceptibility—a major risk factor for disease.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Microfracture for full‐thickness chondral lesions of the knee in elite athletes leads to high return‐to‐play rates

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Injuries to the knee are common in elite athletes and often involve damage to the articular cartilage. Given the high demands of elite sport, full‐thickness articular cartilage defects in the knee can be career‐limiting or threatening.

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Similar dynamic tibiofemoral movements during jump‐landing and walking but distinct hamstrings strength across ACL reconstruction autograft types at mid‐term follow‐up

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Dynamic tibiofemoral movements following anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autografts have not yet been compared to other autografts. We aimed to compare dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing and walking among patients with QT, bone ...

Impact of hamstring versus quadriceps tendon graft on thigh muscle strength and surface electromyography activity after anterior cruciate ligament reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare quadriceps tendon (QT) and hamstring tendon (HT) autografts regarding isometric thigh muscle strength, surface electromyography (sEMG) activity and clinical outcomes following anterior cruciate ligament reconstruction (ACLR).

Muscle fiber conduction velocity is more affected after eccentric than concentric exercise

, 2011
It has been shown that mean muscle fiber conduction velocity (CV) can be acutely impaired after eccentric exercise. However, it is not known whether this applies to other exercise modes.
