Short answer

When designing training protocols that involve cognitive challenges, consider a tiered approach to complexity, starting with lower demands for novices and progressively increasing them for those with higher baseline cognitive abilities to ensure optimal and sustained performance improvements.

Field: Human Factors

Method: Experimental study with repeated measures
Sample: 125 participants
Evidence: Strong effect

Training interventions that increase cognitive complexity can improve an athlete's ability to suppress unwanted responses and manage attention, particularly for individuals who already possess strong inhibitory control. This human factors research insight is drawn from a 2026 study published in Scientific Reports. Using Experimental study with repeated measures with 125 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing training protocols that involve cognitive challenges, consider a tiered approach to complexity, starting with lower demands for novices and progressively increasing them for those with higher baseline cognitive abilities to ensure optimal and sustained performance improvements.

Cognitive load in training enhances inhibitory control, but only for those with high baseline capacity.

Scientific Reports · 2026

Key Findings

01High-IC capacity athletes showed consistent improvements in IC accuracy and response time across all sessions.
02Low-IC capacity athletes initially improved under low executive demands, with improvements later appearing under high executive demands.
03After three months, performance generally declined, except for high-IC capacity athletes in high-demand conditions, where it was maintained.
04Cognitively demanding training was more effective for athletes with higher baseline IC capacity.

Application

Design takeaway

How to apply

When developing training simulations or skill-acquisition programs, implement adaptive algorithms that adjust the cognitive load based on user performance, ensuring that challenges are appropriate for each individual's current skill level.

Project actions

01When designing a training simulation, consider how to vary the cognitive load.
02Think about how to assess a user's baseline cognitive abilities before they start training.

Method & Evidence

AimTo investigate whether cognitive-motor complexity during training interventions leads to long-term adaptations in inhibitory capacity and how an athlete's baseline inhibitory capacity influences these outcomes.

MethodExperimental study with repeated measures

ProcedureParticipants were divided into high and low inhibitory control (IC) capacity groups and underwent one of four basketball dual-task interventions varying in executive demands and physical load. The study assessed the effects of 11 training sessions on IC and re-evaluated performance after a three-month period.

ContextSports training and cognitive performance

Variables

IV["Cognitive-motor complexity of the intervention (high vs. low executive demands, physical load)","Baseline inhibitory capacity (high vs. low)"]

DV["Inhibitory capacity (accuracy, response time)","Performance retention after three months"]

CV["Number of training sessions","Age and gender of participants","Type of sport (basketball)"]

Strengths & Limitations

Strengths

+Large sample size.
+Inclusion of both acute and chronic effects.
+Categorization of participants based on baseline cognitive capacity.

Limitations

It's hard to accurately measure someone's baseline cognitive capacity. Also, the specific sport context might influence how these findings apply to other domains.

Reliability & validity

The study likely employed standardized cognitive tests for IC assessment, contributing to reliability. The use of repeated measures and a control period (three months) enhances internal validity by allowing for within-subject comparisons and assessment of retention. However, external validity might be limited by the specific sport context.

Think critically

To what extent can these findings on inhibitory control in athletes be generalized to other domains requiring complex cognitive processing, such as air traffic control or surgery?

Design Principles

"Adaptive cognitive load: Training complexity should be adjusted based on the individual's current cognitive capabilities to foster effective learning and long-term retention."

Understanding how cognitive load impacts performance is crucial for designing effective training programs. This research suggests that the effectiveness of cognitively demanding training is not uniform across all individuals, highlighting the need for personalized approaches to optimize skill development and performance.

What This Means for Your Design

If you want to get better at focusing and ignoring distractions during a task, doing harder versions of that task can help, but it works best if you're already pretty good at focusing. For people who struggle to focus, easier versions of the task are more helpful at first.

Paragraph starter

The study by Gutiérrez-Capote et al. (2026) demonstrates that training interventions with varying cognitive-motor complexity can significantly impact athletes' inhibitory capacity. Their findings suggest that higher cognitive demands in training are particularly beneficial for individuals with a strong baseline inhibitory control, leading to sustained performance improvements. Conversely, less complex tasks were found to be more effective for those with lower baseline capacity, indicating a need for adaptive training approaches to optimize cognitive development and skill acquisition across diverse user groups.
