Own Typology of Body Posture Based on Research Using the Diers Formetric III 4D System.
J Clin Med
January 2025
Laboratory of Posturology, Collegium Medicum, Jan Kochanowski University, Al. IX Wieków Kielc 19, 25-317 Kielce, Poland.
: Body posture is developmentally variable and individually diversified. As a chain of numerous unconditioned and conditioned reflexes, it is, in its essence, a psychomotor habit. The aim of the study was to create an original typology of body posture based on measurements using the Diers Formetric III 4D system.

Soccer players must react quickly and execute complex mental processes to adapt to competitive scenarios while maintaining peak physical performance. Perceptual-cognitive training methods integrate reaction tasks using nonspecific visual stimuli with game-like motor actions, but the impact on explosive strength responses is unclear. This study investigates the effect of nonspecific visual stimuli with varying perceptual-cognitive constraints on jump performance, including countermovement jump height, reactive strength index modified, action time, and reaction time.

Exp Brain Res

Department of Kinesiology, Michigan State University, 308 W Circle Dr, East Lansing, USA.
A characteristic feature of redundancy in the motor system is the ability to compensate for the failure of individual motor elements without affecting task performance. In this study, we examined the pattern and variability in error compensation between motor elements during a virtual task. Participants performed a redundant cursor control task with finger movements.

Sci Robot
January 2025
Sony Computer Science Laboratories Inc. (Sony CSL), Tokyo, Japan.
For trained individuals such as athletes and musicians, learning often plateaus after extensive training, known as the "ceiling effect." One bottleneck to overcome it is having no prior physical experience with the skill to be learned. Here, we challenge this issue by exposing expert pianists to fast and complex finger movements that cannot be performed voluntarily, using a hand exoskeleton robot that can move individual fingers quickly and independently.

Sci Rep
January 2025
Department of Psychology, University of Konstanz, Konstanz, Germany.
Two approaches to movement selection, if-then rules versus prospective planning, were investigated. Studies have shown that the rule-based approach leads to more efficient movement selection than the plan-based approach, though the resulting movements are the same. This dual-tasking study investigates two hypotheses explaining this discrepancy: The efficiency hypothesis states that the rule-based approach to movement selection is more efficient, and its advantage over the plan-based approach increases under any kind of enhanced task demands.
