Evidence from a 60 s Jump Protocol in National Wrestlers on Effects of Short-Term Plyometric Fatigue on Visual and Auditory Reaction Performance.

Visual reaction time was significantly delayed following the 60-second plyometric fatigue protocol across all measurement conditions.

• VRT for both sides: p=0.019, η²p=0.147
• VRT for right side: p=0.002, η²p=0.250
• VRT for left side: p<0.001, η²p=0.273
• Effect sizes ranged from moderate to large (η²p=0.147 to 0.273)
• Measurements were taken before and immediately after the fatigue protocol

Auditory reaction time showed no significant changes following the plyometric fatigue protocol under any measurement condition.

• All ART conditions showed p>0.19
• Effect sizes were negligible to trivial: η²p≤0.048 for all ART conditions
• ART was assessed separately for right, left, and both sides
• The absence of significant change contrasts with the significant VRT impairment observed in the same participants

The study enrolled 36 male U17 National Team Wrestlers who underwent a repeated-measures design with pre- and post-fatigue reaction time measurements.

• Participants: 36 male U17 National Team Wrestlers
• Mean age: 16.2 ± 0.77 years
• Mean training experience: 7.2 ± 1.8 years
• A 60-second continuous plyometric jump protocol was used to induce acute fatigue
• Data were analyzed using repeated-measures ANOVA with partial eta-squared (η²p) for effect sizes

Reaction times were assessed separately for the right side, left side, and both sides using a standardized computerized test.

• Both visual reaction time (VRT) and auditory reaction time (ART) were measured
• Testing occurred before and immediately after the fatigue protocol
• Measurements were taken for right, left, and bilateral conditions
• A standardized computerized reaction time test was employed

The authors concluded that acute plyometric fatigue primarily disrupts visual-motor pathways rather than auditory-motor pathways in competitive wrestlers.

• VRT impairment was observed across all laterality conditions while ART remained unaffected
• The authors suggest these findings have implications for training and match preparation in combat sports
• The differential effect implies that visual and auditory sensory-motor integration are not equally susceptible to acute high-intensity fatigue
• The study context was combat sports, where rapid visual and auditory responses are described as essential for offensive and defensive actions
