Is Cognitive-Motor Training with Unspecific Visual Stimuli Appropriate for Improving Neuromuscular Performance? A Study on Volleyball Athletes' Jumping Ability

New training methodologies for team sports emphasize the concurrent development of cognitive and neuromuscular abilities to enhance motor execution and decision-making. However, research on performing high-intensity motor-actions with unspecific visual stimuli for neuromuscular optimization remains limited This study evaluated the effects of four unspecific perceptual-cognitive dual tasks on countermovement jump (CMJ) performance—used as an indicator of force application ability—in federated volleyball players (n = 11) and examined how these effects evolved over five sessions. Results showed a significant reduction in jump height across all conditions, with the largest effect in the divided-attention simple reaction-time task (JD-A/SRT, p
