ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

Experimental Physiology, Volume 111, Issue 9, Page 4153-4165, 1 September 2026.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

Reliability of the Unilateral Countermovement Jump and Bilateral Countermovement Jump in detecting Interlimb Asymmetries within Collegiate Dancers

, 2023
There has been a growing body of research looking into the assessment of interlimb asymmetries. Interlimb asymmetries refers to the differences in strength from one limb compared to the other.

NEX4EX – A novel exercise device enabling resistive, plyometric and sensorimotor training during deep‐space missions: A case report

Experimental Physiology, Volume 111, Issue 9, Page 3936-3943, 1 September 2026.
Abstract During weightlessness, the human neuro–muscular–skeletal system undergoes maladaptation to the microgravity environment. The European Space Agency (ESA) project NEX4EX, ‘Novel Exercise Hardware for Exploration’, developed an advanced multipurpose exerciser offering resistive (RES), plyometric (PLYO) and sensorimotor (SENSO) exercises.

Why is countermovement jump height greater than squat jump height?

, 1996
In the literature, it is well established that subjects are able to jump higher in a countermovement jump (CMJ) than in a squat jump (SJ). The purpose of this study was to estimate the relative contribution of the time available for force development and

Dryland Performance Tests Are Not Good Predictors of World Aquatics Points in Elite Male and Female Swimmers

Sports
Background: Swim performance can be reliant on strength and power. Standardisation of swim performance in different events, distances, and sexes can be completed using World Aquatics points, allowing for ranking of swimmers. The aim of this retrospective

Influence of weighted squat jumps on countermovement jump in high level basketball players. [PDF]

, 2018
The objects of the study: Influence of squat jumps with different additional weight to countermovement jump height and variability after stimulus. Is it possible to make a hypothesis that squat jumps with additional weight of 50% body mass have more ...
