Ground reaction force data were collected at a sampling rate of 250 Hz using two force platforms (9260AA Kistler Instruments, Hampshire, UK) embedded in the floor. Synchronously, an eight camera Oqus motion capture system (Qualisys, Sweden) was used to collect kinematic data at a sampling frequency of 250 Hz. Twenty one retro-reflective markers were placed on each subject prior to data collection27 (link). Moreover, FitLight Trainer lights were used (Fitlight Sports Corp., Canada) in order to simulate an attack and to determine if the block was high enough to be effective.
Eight camera oqus motion capture system
Manufactured by Qualisys
Sourced in Sweden
The Eight camera Oqus motion capture system is a high-precision motion tracking solution designed for laboratory and research applications. It utilizes eight cameras to capture and record the movement of markers or objects within a defined capture volume. The system provides accurate, real-time data on the position and orientation of the tracked elements, enabling detailed analysis of various types of motion.

Ground reaction force data were collected at a sampling rate of 250 Hz using two force plates (9260AA Kistler Instruments, Hampshire, UK) embedded in the floor. Synchronously, an eight camera Oqus motion capture system (Qualisys, Sweden) was used to collect kinematic data at a sampling frequency of 250 Hz. Twenty-one retro-reflective markers were placed on each subject prior to data collection [35] .
In order to create the unplanned jumps, participants performed a FitLight Trainer™ sequence programming protocol (Fitlight Sports Corp., Canada). This allowed a light sequence which was used as a target to create visual reaction information to the player, such as showing the blocking direction, whilst checking that the block has been made at the correct height.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
