About this study
Official title: Effects of Mental Fatigue and Different Nap Durations on Volleyball Performance and Brain Activity
Mental fatigue is known to impair cognitive and physical performance in athletes, but the effectiveness of different nap durations in counteracting these effects remains unclear. The purpose of this randomized crossover study is to investigate the effects of mental fatigue and different nap durations (20, 40, 60, and 90 minutes) on volleyball-specific performance and electroencephalographic (EEG) activity in trained male volleyball players. Mental fatigue is induced using a 15-minute Stroop task. Performance outcomes include the Volleyball Agility Test (VAT) and Countermovement Jump (CMJ), while cortical activity is assessed using resting-state EEG recordings. The findings are expected to improve understanding of the neurophysiological mechanisms underlying mental fatigue and recovery and to provide evidence-based recommendations regarding optimal nap duration for athletes.
Read the detailed description
Mental fatigue has emerged as an important factor influencing athletic performance by impairing attention, executive function, decision-making, and motor performance. Volleyball is a sport requiring rapid cognitive processing, agility, explosive power, and precise motor control, making athletes particularly vulnerable to the detrimental effects of mental fatigue. Although daytime napping has been proposed as an effective recovery strategy, the optimal nap duration for restoring sport performance and brain activity following mental fatigue remains uncertain.
This study employs a randomized crossover repeated-measures design in which each participant completes six experimental conditions: Control, Mental Fatigue, Mental Fatigue followed by a 20-minute nap, Mental Fatigue followed by a 40-minute nap, Mental Fatigue followed by a 60-minute nap, and Mental Fatigue followed by a 90-minute nap. Mental fatigue is induced using a standardized 15-minute computerized Stroop task. A 72-hour washout period is maintained between consecutive experimental sessions.
Primary assessments include volleyball-specific agility performance, countermovement jump performance, and resting-state electroencephalographic (EEG) recordings obtained before and after mental fatigue and following the nap intervention. EEG analyses focus on spectral power in the delta, theta, alpha, and beta frequency bands as well as Theta/Alpha and Theta/Beta ratios.
The study aims to determine whether different nap durations differentially improve volleyball-specific performance and cortical activity following mental fatigue. The results are expected to provide practical recommendations for coaches and athletes regarding evidence-based recovery strategies while contributing to a better understanding of the neurophysiological mechanisms underlying mental fatigue and post-nap recovery.

What is being measured
The primary outcome is the main question the study is designed to answer.
EEG Spectral Power
Resting-state electroencephalographic (EEG) activity was recorded from the Fz, Cz, Pz, O1, and O2 electrode sites. Power spectral density was analyzed for the delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), and beta (13-30 Hz) frequency bands. All frequency-band power values were expressed in microvolts squared per hertz (µV²/Hz).
Measured: At baseline, immediately after the mental fatigue task, and immediately after completion of the assigned intervention during each experimental session.
EEG Theta/Alpha Ratio
The theta-to-alpha power ratio was calculated from resting-state EEG recordings obtained from the Fz, Cz, Pz, O1, and O2 electrode sites by dividing theta-band power by alpha-band power. The outcome was expressed as a unitless ratio.
Measured: At baseline, immediately after the mental fatigue task, and immediately after completion of the assigned intervention during each experimental session.
EEG Theta/Beta Ratio
The theta-to-beta power ratio was calculated from resting-state EEG recordings obtained from the Fz, Cz, Pz, O1, and O2 electrode sites by dividing theta-band power by beta-band power. The outcome was expressed as a unitless ratio.
Measured: At baseline, immediately after the mental fatigue task, and immediately after completion of the assigned intervention during each experimental session.
Volleyball-Specific Agility Performance
Volleyball-specific agility performance was assessed using the Volleyball Agility Test (VAT). Performance was quantified as test completion time (seconds), with lower values indicating better agility performance.
Measured: Immediately after completion of each experimental protocol.
Countermovement Jump Height
Countermovement jump (CMJ) performance was assessed using the My Jump Lab application by measuring jump height in centimeters (cm), with higher values indicating better jump performance.
Measured: Immediately after completion of each experimental protocol.
Secondary outcomes (3)
Countermovement Jump-Derived Mechanical and Kinematic Parameters
Countermovement jump (CMJ)-derived mechanical and kinematic parameters were obtained using the My Jump Lab application from the CMJ assessment performed at the end of each experimental protocol. Participant jump height and body mass were entered into the application's manual data-entry module, which provided flight time (ms), average velocity (m/s), take-off velocity (m/s), and impulse (kg·m/s). These parameters were analyzed as complementary derived measures of CMJ performance.
Measured: Immediately after completion of each experimental protocol.
Pittsburgh Sleep Quality Index (PSQI) Score
Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), a validated self-reported questionnaire that evaluates sleep quality over the previous month. The PSQI consists of 19 self-rated items yielding a global score ranging from 0 to 21, with higher scores indicating poorer subjective sleep quality.
Measured: Baseline (before the first experimental session).
Visual Analog Scale (VAS) Score for Perceived Nap Quality
Perceived nap quality was assessed using a 100-mm Visual Analog Scale (VAS). Participants rated the overall quality of their daytime nap on a horizontal line ranging from 0 mm (very poor nap quality) to 100 mm (excellent nap quality). Higher scores indicate better perceived nap quality.
Measured: Immediately after each daytime nap intervention (20-, 40-, 60-, and 90-minute nap conditions).
