Reproducibility of trunk isoinertial dynamic performance in patients with low back pain.

Journal of Spinal Disorders, 1992
The purpose of this study was to assess consistency of response in repeated measurements of isoinertial trunk performance among patients with low back pain. An underlying assumption was that inconsistency can detect lack of effort.

Strong Proton-Phonon Coupling Drives Fast Ion Transport in Perovskites. [PDF]

Adv Sci (Weinh)
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

The physical determinants of maximal jumping time of flight in elite trampolining

European Journal of Sport Science, Volume 23, Issue 12, Page 2283-2290, December 2023., 2023
ABSTRACT Time of flight (ToF) is an objective scoring component of elite trampolining, assessed in training by maximal jump tests. The aim of this study was to assess the relationship between physical floor based performance meaures and 20‐maximum ToF. Thirty‐two elite level gymnasts (13 senior; 19 junior) performed a battery of floor based tests and a

Relative Isoinertial Performance Expressions for the Isostation B-200 [PDF]

Journal of Orthopaedic & Sports Physical Therapy, 1990
Low back internal loads are dependent, in part, upon the weight of the body segments and the lengths of their moment arms. Musculoskeletal performance appears to be influenced by anthropometric characteristics. The purpose of this investigation was to compare dynamic isoinertial performance values to selected individual and permutated anthropometric ...

Flywheel resistance training promotes unique muscle architectural and performance-related adaptations in young adults. [PDF]

Eur J Sport Sci
Abstract The purpose of this study was to examine the skeletal muscle hypertrophic, architectural, and performance‐related adaptations in response to volume‐matched, total‐body flywheel versus traditional resistance training in a randomized, non‐exercise controlled study in physically active young adults. Thirty‐one healthy young adults (24 ± 3 y) were
