Impact of elbow stiffness on running economy in trained athletes.

AI Article Synopsis

Article Abstract

Background: Elbow injuries are likely to generate a decreased range of motion (ROM), which might negatively affect athletic performance. To date, the effect of elbow stiffness on endurance running performance has never been studied. We conducted an observational, prospective, cross-over study to examine the impact of elbow stiffness on running economy.

Methods: Twenty trained athletes performed running economy tests at 12 km·h, with and without a limited elbow ROM (flexion: 90°, extension: 45°), imposed by a dynamic brace mimicking a severe elbow stiffness. Relative intensity and performance indexes were measured during a subsequent maximal incremental exercise test.

Results: Running economy was measured at 180 ± 10.6 mlO·km·kg with a full ROM, and 180.2 ± 12.3 mlO·km·kg with the limited ROM showing a non-significant 0.1% difference ( = 0.871).

Discussion: Athletes experiencing post-traumatic elbow stiffness can find reassurance in knowing that it does not seem to impact a crucial metric of endurance running performance, namely running economy. Further research could explore elbow movement at different intensities of running, from higher aerobic speeds to sprinting.

Background: Literature assessing elasticity in rotator cuff (RC) muscles with shear wave elastography (SWE) is growing but little is known about the overall measurement properties. However, this information is crucial before implementation in research or practice. The objective of this review was first, to systematically investigate the evidence regarding reliability and validity of rotator cuff (RC) muscles shear wave elastography (SWE).

Background: The present study aimed to compare the functional outcomes of hinged external fixators and non-external fixation in open elbow arthrolysis (OEA) for post-traumatic elbow stiffness (PTES) and to evaluate their applicability and limitations in patients with posttraumatic elbow stiffness.

Methods: The clinical data of patients with PTES treated with OEA at our hospital between March 2015 and June 2022 were retrospectively analyzed. The assessed variables were the operation time, intraoperative blood loss volume, duration of hospitalization, and treatment costs.

Purpose: Varus posteromedial rotatory instability (VPMRI) involves anteromedial coronoid fracture (AMCF), lateral ulnar collateral ligament (LUCL), and medial collateral ligament (MCL) injury. There is no general consensus regarding the surgical treatment, but most surgeons recommend internal fixation of the coronoid along with primary ligament repair. This methodology involves postoperative immobilization to allow ligament healing, occasionally associated with stiffness.

Hypothesis And Background: Reverse shoulder arthroplasty (RSA) exhibits favorable outcomes in managing rotator cuff arthropathy, primary glenohumeral arthritis, and complex proximal humeral fractures. Despite its success and reliability, certain patients experience persistent pain and stiffness. The clinical utility of therapeutic arthroscopy in RSA patients remains an area for investigation.
