Deception studies manipulating centrally acting performance modifiers: a review.

Area of Science:

• Exercise Physiology
• Sports Psychology
• Neuroscience

Background:

• Athletes use self-regulation to optimize performance by adjusting pacing strategies based on internal and external cues.
• The brain's performance modifiers, integrating feedforward and feedback, are crucial for regulating exercise intensity and duration.
• Deception research explores manipulating these modifiers to improve self-regulation and athletic output.

Purpose of the Study:

• To critically evaluate methods used in deception research to manipulate centrally controlled performance modifiers.
• To assess the effectiveness of various deception techniques in influencing self-regulation and exercise performance.
• To identify successful deception strategies and understand their role in exercise regulation.

Main Methods:

• Systematic review and critical evaluation of 31 deception studies in exercise science.
• Analysis of methods manipulating performance modifiers like perceived endpoint, feedback, self-belief, and prior experience.
• Assessment of study outcomes for positive, negative, or null effects on performance and pacing.

Main Results:

• Ten of the 31 reviewed studies reported significant positive effects on athletic performance.
• Inconsistent results were observed across studies due to variations in manipulation methods and outcome measures.
• Deception techniques show potential for influencing pacing and enhancing self-regulated exercise.

Conclusions:

• Deception strategies, particularly expectation manipulation, can be effective in facilitating athletic performance.
• Further research is needed to elucidate the precise mechanisms by which deception influences pacing and self-regulation.
• Integrating theoretical propositions with practical, ecologically valid deception methods is crucial for future studies.
