Summary
This study introduces a complex stop signal task for lower limb movements, demonstrating its feasibility and reliability. Findings support its use in developing advanced sports performance tests.
Area of Science:
- Sports Science
- Motor Control
- Human Movement Analysis
Background:
- The stop signal task (SST) is crucial for measuring inhibitory control.
- Existing SSTs often lack effector-specificity and complexity for applied contexts like sports.
Purpose of the Study:
- To develop and validate a proof-of-concept for a complex, effector-specific stop signal task for lower extremities.
- To assess the impact of varying delays and sessions on performance metrics.
- To evaluate the reliability of the developed task.
Main Methods:
- Sixteen participants completed a novel lower extremity SST using the Fitlight System™.
- Data on response time, stop signal reaction time, and accuracy were collected.
- Two-way repeated-measures ANOVA and intraclass correlation coefficients were used for analysis.
Main Results:
- A significant main effect of delay was observed across all measured outcomes.
- An interaction between delay and session significantly affected accuracy.
- The task demonstrated substantial reliability, influenced by specific delays.
Conclusions:
- The developed stop signal task is feasible for complex lower extremity movements.
- This work provides a foundation for creating new inhibitory control tests in sports.
- The findings highlight the importance of task complexity and effector-specificity in motor control research.

01:19Contact-dependent Signaling
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

01:30Assembly of Signaling Complexes
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.

01:22Amplifying Signals via Enzymatic Cascade
When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
