Physical Characteristics of Fast Roping in British Elite Law Enforcement Officers

European Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT Elite law enforcement and special forces operators around the world have a unique skill set, including some risky methods of entry into a scene of operation. With fast roping being actively utilized by this population, it is important to gain an understanding of the physical demands of the task.

Biodegradation Behavior of Neat PLA Fibers Under Controlled Industrial Composting Conditions: Fiber Characterization and Physical Changes During the Composting Process

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Poly(lactic) acid (PLA) biodegradability in fiber form is relatively unexplored. This study shows that the drawing of the fibers during production affects the mechanical properties but slows down the biodegradation of the PLA. Biodegraded undrawn fibers showed peeling whereas drawn fibers showed crack formation on the surface.

The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.

Static Stretching Acutely Reduces the Ergogenic Effects of Caffeine on Sprint Performance but Not Maximal Ball Velocity in Football Players

European Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the independent and combined effects of caffeine and static stretching (SS) on maximal ball velocity and 30‐m sprint performance. Sixteen male amateur football players performed 30‐m sprint and an instep kicking ball velocity test under six conditions.
