Relationship between impulse and kinetic variables during jumping and landing in volleyball players

Abstract

Background This study examined the relationships between impulse and kinetic variables during jumping and landing in elite young male volleyball players. Methodology Eighteen players were recruited and asked to jump on a force plate, which allowed for the direct extraction of jump and landing kinetic data. The data was then analysed using stepwise regression to explore the relationship between landing impulse and various kinetic variables. Results Our findings revealed a significant positive relationship between the peak rate of force development concentric (PRFD CON) and impulse at landing (β = 0.537, p = 0.02). In a secondary analysis, we found that PRFD CON (β = 0.497, p = 0.01) and time to peak power concentric (TPPC) (β = 0.424, p = 0.04) were also positively correlated with landing impulse. Importantly, PRFD CON and TPPC were the variables that had the most muscular predictive power for impulse at landing. Conclusion These findings offer crucial insights into the biomechanics of jumping and landing in elite young male volleyball players, informing the development of more effective training programs. Our study identifies PRFD CON and TPPC as critical factors for improving landing impulse, emphasizing the need to consider multiple kinetic variables when designing training programs for explosive skills. These insights can help optimize performance and reduce the risk of injury in elite young male volleyball players.

“…When the slope presents a centripetal force output curve that is steep (a pointy kurtosis), it indicates that an excellent RFD can be produced [15]. The so-called duration of passage refers to the total time that an athlete spends in the air during a jump, which is the process from leaving the ground to the first time that they touch the ground when they land [16]. Lower limb power affects the duration of passage because of the eccentric and concentric phases of the stretch-shortening cycle of the lower limb, muscle extension, and stretch reflexes that generate force [17].…”
