Biomechanics of Copenhagen Adduction Exercise and Eccentric Hip Adductor Exercises on a Novel Isokinetic Dynamometer With Within‐Session Repeatability

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 9, September 2026.
ABSTRACT This study biomechanically evaluated the eccentric phase of short and long lever Copenhagen adduction exercise (CAE) and compared them with unilateral and bilateral eccentric hip adductor exercises performed on a novel eccentric hip adductor dynamometer (EHAD). Fifteen participants completed two CAE variations and five EHAD exercises.

Movement Strategies During the Penultimate and Final Steps of a Change of Direction Following Arthroscopic Partial Meniscectomy

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 9, September 2026.
ABSTRACT Persistent knee offloading is well‐documented after arthroscopic partial meniscectomy (APM). Yet, it remains unclear if this extends to higher‐demanding change‐of‐direction (CoD) tasks and how step‐specific strategies influence joint loading.

Jumping on the moon as a potential exercise countermeasure

Experimental Physiology, Volume 111, Issue 9, Page 4073-4088, 1 September 2026.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...
