Results: Spike velocity correlated significantly with strength performance of the dominant shoulder (internal rotators) and of the dominant elbow (flexors and extensors) in the concentric mode. Negative correlations were established with the concentric external rotator on internal rotator ratio at 400 deg/s and with the mixed ratio (external rotator at 60 deg/s in the eccentric mode on internal rotator at 240 deg/s in the concentric mode).
Velocity is the speed of an object in a particular direction. I think the best example of velocity during volleyball is a spike, because every part of the spike is dependent upon velocity. Starting from the approach, to the arm swing, and even the follow through.
Spike and serve velocity performance showed high stability and reliability (CV ≤ 2.4%, ICC ≥ 0.99, respectively). The F 0 and P max obtained from jump FV profiling, the V 0 and P max obtained from sprint FV profiling, and the F 0 and P max obtained from bench press throw FV profiling showed a positive association with spike ball speed; this association had moderate ( r = 0.44; p <0.05) to very large effects ( r = 0.81; p <0.01).
Spike velocity correlated significantly with strength performance of the dominant shoulder (internal rotators) and of the dominant elbow (flexors and extensors) in the concentric mode.
The objective of this study was to investigate the relationship between movement characteristics and female' spike jump performance and to identify the most relevant aspects of jump height and ball velocity. Design: Single group correlation and regression.
This argument indicates the need to focus on horizontal velocity during vertical movement and strengthens the association between V 0 and ball speed since it is known that vertical force application becomes more important for spike performance as running velocity increases. During a spike jump, the stretch shortening cycle and stiffness play a key role in absorbing and producing force in the shortest time possible, especially in volleyball plyometric actions.
The average speed of a volleyball spike from men is most impressive at the Olympic beach or indoor level. Bulgaria’s Matey Kaziyski, for example, recorded a spike that reached 132 km/h, which is equivalent to 80.8 mph, in an international volleyball match in 2012. The average speed of an Olympic volleyball spike from men is roughly 70 to 80 mph.
Spikes, or attacks, are typically high-velocity shots (ball speeds can approach 28 m per second). 18 An elite volleyball athlete, practicing between 16 and 20 hours a week, may perform 40 000 (or more) spikes in a single season. 19 Not surprisingly, players who specialize in the attacking aspect of the game (eg, outside hitters, opposites, and middle blockers) are more likely to develop shoulder pain and dysfunction. 25
