The Biomechanics of Jumping

Comparative Analysis of Jumping and Landing Velocity of the Young Elite Spikers of the Iranian National Volleyball Team While Performing Block Jump

Objective: Accurate velocity analysis is essential when performing the block jumping technique on the net by various spikers because it will improve this performance and prevent injury. This study aimed to compare the jump and landing velocity of the Iranian national team’s young elite spikers when performing block jump skills.  Methods: A total of 21 young elite male volleyball players of the...

Neuromuscular adaptations to 4 weeks of intensive drop jump training in well-trained athletes

This study examined the effects of 4 weeks of intensive drop jump training in well-trained athletes on jumping performance and underlying changes in biomechanics and neuromuscular adaptations. Nine well-trained athletes at high national competition level within sprinting and jumping disciplines participated in the study. The training was supervised and augmented feedback on performance was used...

Optimizing segmental movement in the jumping header in soccer.

This study looks at segmental movements in the jumping header from an optimization viewpoint. Investigations on the header so far have focused on head restriction in the movement but have not clarified how and to what extent body segments influence the performance of the skill. In the present study a biomechanical model was used to analyze the jumping header in simulated competition to give a c...

Application of a tri-axial accelerometer to estimate jump frequency in volleyball.

Patellar tendinopathy is prevalent among athletes, and most likely associated with a high jumping load. If methods for estimating jump frequency were available, this could potentially assist in understanding and preventing this condition. The objective of this study was to explore the possibility of using peak vertical acceleration (PVA) or peak resultant acceleration (PRA) measured by an accel...

The influence of the biarticularity of the gastrocnemius muscle on vertical-jumping achievement.

Hypotheses concerning the influence of changes in the design of the human musculoskeletal system on performance cannot be tested experimentally. Computer modelling and simulation provide a research methodology that does allow manipulation of the system's design. In the present study this methodology was used to test a recently formulated hypothesis concerning the role of the biarticularity of t...
