1 INTRODUCTION
OptoJump Next is an innovative system of analysis and measurement that brings a new philosophy
of performance assessment and optimization to the world of competitive sport. By acquiring the
fundamental parameters that characterize the level of an individual’s performance and physical
condition, OptoJump Next allows coaches, trainers and researchers to constantly test and monitor
their athletes. This makes it possible to ascertain the abilities or physical fitness of an athlete in a
simple and instantaneous way, creating even over a period of time a database that allows to
compare values for that athlete or different athletes (even at a distance of months or years).
Quick Start: Online Video Tutorial
For a brief introduction to the software for OptoJump Next, we strongly recommend you watch the
introductory webcast available on the official site:
http://www.optojump.com/support/software-tutorial.aspx
The software modules will be illustrated in about ten minutes. After watching it, you will be able to
perform the most common operations, which can be summarized as follows:
Graphic and surfing interface
Checking of general parameters
Checking of status of bars and webcams
Insertion of athletes’ data
Performance of tests
Viewing results
Comparison of tests and statistics
Printing and exporting of data to other programs
Figure 1 – Webcast Tutorial
Version 1.10 Page 8 of 203
1.1 SINGLE METER
In this configuration OptoJump Next allows already to carry out various test types:
1.1.1 JUMP TEST
A series of exercises (squat jump, counter movement jump, drop jump, continuous jumps, jumps on
one leg, etc.) and protocols ('Drift' for dynamic stability, '5 Dot Drill' for reactivity and endurance,
'Single Leg Three Hops' to verify the bending capacity and stability of the knee) are pre-configured.
At the same time, the user can easily create customized tests or protocols.
1.1.2 TAPPING/FREQUENCY TEST
This type of test is ideal for exercises where separate results are required for the left and right foot
(e.g. tapping/frequency test, side movement, walking on the spot, etc.)
1.1.3 REACTION TEST
This test detects the time between one optical/acoustic impulse and the patient's movement. It can
be used to measure simple reactions or more complex movements
Version 1.10 Page 9 of 203
1.2 SINGLE METER ON TREADMILL
1.2.1 GAIT ANALYSIS, RUN ANALYSIS
Positioned on the side bars of a treadmill, OptoJump Next becomes a real portable lab for small
spaces and with reduced costs. The system is compatible with the wide majority of treadmills and
no synchronization is necessary to start and carry out a test.
Version 1.10 Page 10 of 203
1.3 THE MODULAR SYSTEM
In this configuration, OptoJump Next allows to carry out:
1.3.1 GAIT TEST
Gait tests can consist of simple exercises (moving from A to B), but also of more complex ones, such
as 'roundtrip' or walking backwards. They can be more complex, if needed, adding obstacles (e.g.
plastic cones) or actions to be carried out between the various gait phases (sitting down and getting
up before coming back, for example) or simultaneously.
1.3.2 RUNNING TEST
Running tests, just like gait tests, can be carried out either starting from a stand or running, to
analyze the various phases, how the incremental weariness acts on the patient at each round
installing the system on a track, measuring the time of a change of direction and the following
acceleration, and so on…
Thanks to the practical and innovative assembling system using caps, the modular system is
assembled in a few minutes and does not require cables to connect the bars or further net adapters.
The length goes from a minimum of 2 meters to a maximum of more than 100 meters.
Version 1.10 Page 11 of 203
1.4 THE TWO-DIMENSIONAL SYSTEM
Starting from version 1.8 of the OptoJump Next software it is possible to use a particular bar
configuration for obtaining a two-dimensional measurement area. To the classic bars (which we will
call X) more bars (Y) can be added to form a rectangle.
MAX 6 mt. (Eg. 5mt + 0,5mt. x 2 of space)
MAX 6 mt.
TX bar(s)
RX bars
TX bars
X
Y
The regular closing Y TX bar is usually a bar WITHOUT interface drum. Updating the firmware of the
TX bar with drum (already included with all articles having a serial number higher than 00500) this
last hardware type can also be used. Therefore with a 5-meter modular system it is for example
possible to use the complete hardware building a 4-meter-long linear gait system. For serial
numbers lower than 00500 it is possible to ship the bar to Microgate or a distributor and receive a
free update (shipping costs for sending and receiving are excluded). It is also possible to buy one or
more additional single TX bars.
Version 1.10 Page 12 of 203
If using a Y-bar with drum, make sure that the power supply is SWITCHED OFF (power off).
TX bar with interface

The bars situated on the perpendicular sides are connected using a variable-length cable (eg.
$CAB155, 1.5m long); this allows to distance the actual measurement area (the rectangle formed
by the regular bars and highlighted in gray in the following picture) of the Y bars; this area allows
the patient to leave the test area without having to jump over the bars or, more frequently, turn
around by 180° and go back. In fact, the software allows to carry out an undefined number of
back/forth courses recording a sufficient number of steps also in case of linear systems of only a few
meters.
Version 1.10 Page 13 of 203
1.5 THE GYKO INERTIAL SYSTEM
Gyko is a new tool, developed by Microgate, which enables obtaining information on the kinematics
of any body segment while making a movement.
Gyko contains the latest generation components that are used for making accurate and repeatable
measurements of acceleration, angular velocity and magnetic field in three dimensions.
3D accelerometer, to measure the linear accelerations to which the device is subjected.
3D gyroscope, to measure the angular velocities of the device.
3D magnetometer, to measure the magnetic field to which the device is subjected.
Gyko is able to provide the measured data up to 1000 times per second guaranteeing an extremely
high temporal resolution of the data. The data can be transmitted to the PC via a Bluetooth
connection or be stored on a MicroSD card.
From the measured data, through advanced software algorithms, it is possible to describe the
kinematics of the body segment to which Gyko is fastened so as to provide the user with summary
information about the quality of the analyzed movement.
Gyko can be used in combination with the OptoGait systems or independently.
Version 1.10 Page 14 of 203
1.5.1 GYKO TO ANALYZE WALKING, RUNNING AND MARCHING IN PLACE
Gait analysis is one of the most widely used methods to determine any disorders of the nervous
and/or musculoskeletal system. With OptoGait you can estimate the space-time parameters of the
gait and isolate individual phases of the step, then accurately describe the behaviour of the lower
body.
Gyko, placed in the area beneath the shoulder blade by using a special bib with a comfortable 3button fastening, enables naturally integrating the information measured on the ground with the
kinematics of the trunk in order to provide accurate information on the stability and coordination
of the upper body.
The movement of the trunk is analyzed in each phase of the step and, through advanced algorithms,
specific parameters of the analyzed test are estimated such as:
Antero-posterior and medio-lateral imbalance.
Main directions and breadth of the movement of the trunk.
Upper Phase Coordination Index (UPCI) that describes coordination in the rotation of the
trunk.
Phase difference between the lower body and the upper body.
RMS, Harmonic Ratio and Harmonicity index describing gait stability.
For details on the various columns see Sect.
0
Version 1.10 Page 15 of 203
1.5.1.1 DYNAMIC STABILITY
In addition to graphics for Step, Stride, flight/contact times, etc. with Gyko there is another one
called Dynamic Stability that can be activated from the legend on the left.
The graphic is an ellipse whose size represents:
how far the trunk rotates along the Antero-Posterior (AP) and Medio-Lateral (ML)
directions; the larger the area of the ellipse the more the trunk rotates.
in which direction the movement is prevalent. If the ellipse is stretched towards AP or ML
the movement of the trunk is prevalent in that direction.
The two horizontal and vertical bars below and to the right of the ellipse represent respectively the
offset of the ML/AP movement. The green/orange/red colour depends on the Bad and Warning
thresholds set in the Configuration panel (Area Threshold affects the colours of the ellipse and the
shades above for the gauges)
Set the Mode to "Dynamic Stability", the number of data on which to calculate the averages and the
two pairs of thresholds (the first pair for the two gauges and the second pair for the ellipse).
Version 1.10 Page 16 of 203
1.5.2 GYKO FOR JUMP ANALYSIS
Using field tests and in particular vertical jump analysis has always been a widely used method for
evaluating lower limb muscle strength. OptoGait is the instrument used to measure and objectify
the main features of a jump such as flight and contact time.
Gyko placed near the centre of mass with a special belt enables enriching the temporal data with a
variety of information regarding the dynamics of the jump. It is then possible to measure lower limb
strength directly and, using appropriate algorithms, accurately and repeatably provide data relating
both to the eccentric loading phase and to the concentric thrust phase.
The movement of the trunk during the flight and contact phase is analyzed and provides, among
other things, the following additional parameters (for all the others see Sect. 5.1.2.1):
Eccentric and concentric work and duration.
Force, Velocity and Maximum Power.
Rate of Force Development and Landing Rate.
Version 1.10 Page 17 of 203
1.5.3 GYKO FOR POSTURE ANALYSIS
Postural analysis is frequently used to evaluate the stability and balance of a quiet standing subject.
Gyko, placed on the trunk or at the level of the centre of mass, provides important information
about the body sway of the subject and through appropriate protocols it enables evaluating the
relative contribution made by the various components of the postural system (visual, proprioceptive
of different origin, labyrinthine, etc.).
Gyko lets you simply and quickly obtain the best known indexes concerning the projection of the
body's centre of gravity on the ground.
The main indexes returned are:
Projection length and area.
Projection travel speed.
Sway frequency
In this case the graphic is a "projection" showing all the movements (the red dot indicates the
position at the end of the test) and an overlay of the ellipse already seen in Sect.
1.5.1.1
. To the right
there are two graphs, one for the antero-posterior movements and the other for the medio-lateral
movements with the time being the abscissa and the movement in mm the ordinate.
The test can be done with a custom "Static Test" (Sect. 5.1.6) or with the default Body Sway protocol
(Sect. 6.8) For all the details shown in the Summary Data please see Sect. 5.1.6
Version 1.10 Page 18 of 203
1.6 ENVIRONMENTAL CONDITIONS AND DISCLAIMERS

2.1 DESCRIPTION
The welcome screen of the OptoJump Next software shows a horizontal bar with the most
important menu items and an area with News and Events, automatically updated from the web site
www.optojump.com in the appropriate language. If a network connection is not present, the
information will not be downloaded; it is also possible to deactivate the Internet connection with a
configuration parameter (see chap. 4.4.1.7). Click on a news title or an event to open the complete
description in a browser window.
Figure 9 – First page
The interface with which the OptoJump Next system is managed is divided into three main sections:
Athletes, Tests and Results.
Version 1.10 Page 25 of 203
2.2 ATHLETES
In this section the profiles of the athletes or patients are created and catalogued. Each profile can
contain many items of information (personal data, notes, athlete’s photo, etc.). Membership Groups
can be created to improve subdivision into different categories when the tests are to be performed.
For example, a group “Football” can be created with its subgroups ‘Attackers’, “Midfielders” and
‘Defenders’.
2.3 TEST
This section is the software’s nerve center. It is accessed to devise and configure new tests (jump,
reaction, running, etc.) and to perform tests by choosing from the pre-defined tests or those created
by the user. It is then possible to program sequences of tests in order to make one or more athletes
perform a number of tests.
During performance the user sees the evolution of the test in real time by means of numerical,
graphical and video data. This data can be saved and stored for immediate review or future
consultation. Depending on the user’s requirements, information not of interest can be temporarily
hidden in order to highlight other information. For example, the charts and tables can be hidden to
show only the videos in larger size.
2.4 RESULTS AND VIDEO ANALYSIS
In this section it is possible at any time to call up previously performed tests. By displaying the
results, it is possible to compare the images with the numerical and graphical data. The video images
are synchronized with the athletes’ movements. This makes it possible to accurately establish what
happened when a certain piece of data was acquired. For example, if a contact time is too long, it is
possible to find out why by observing the images at the time that value was recorded.
The speed of the video can be reduced down to ‘frame by frame’ or still picture. There is also a video
analysis utility that makes it possible to draw on the still picture, thanks to various graphical tools
(lines, arcs, circles, ruler, goniometer, etc.).
In the Results section, it is also possible to compare two or more tests without the assistance of
additional software: for example, it is possible to ascertain the performance of an individual over a
period of time or compare the results of tests performed by two or more different athletes.
All the data, numerical as well as graphical, can be printed or exported in the most common formats
(PDF, Excel, Word and HTML).

3 OPTOJUMP NEXT DRIVER AND HARDWARE INSTALLATION
3.1 DRIVER INSTALLATION
For correct functioning of the program, the respective drivers for the OptoJump Next hardware and
the webcam must be installed.
The OptoJump Next software installation file already contains the required drivers.
In the case of the Vista operating system it has been found that if the installation program is not run
as ‘Administrator’, the drivers are not installed. In this case install the two drivers separately. These
are available on the Microgate USB key supplied with the hardware or on the site
www.optojump.com in the 'Support' section.
To check that the drivers have in fact been installed, connect the two devices (OptoJump Next
hardware and webcam). If installation has not taken place, the operating system will signal an error.
In this case disconnect the hardware, install the drivers again and reconnect the hardware.
3.2 OPTOJUMP NEXT HARDWARE INSTALLATION
Attention must be paid when installing the OptoJump Next bars, particularly when inserting the caps
for connecting the bars.
The distinctions to be made between the bars are between Tx and Rx and additionally between bars
with interface (silver drum at start of bar) and without interface. Only the interfaces have an OFF
switch.

Version 1.10 Page 27 of 203
Below is the step-by-step procedure for bar installation:
Switch off the OptoJump Next device
Place the two OptoJump Rx and Tx bars facing each other at a minimum distance of one
meter (maximum 6 meters)
Figure 11 – Maximum distance
If a number of bars connected together are used, pay attention to the insertion of the
caps (see figures below). Check that the caps are firmly inserted. If insertion is incorrect,
the software may not function correctly.
Figure 12
Figure 13
Figure 14
Figure 15
Version 1.10 Page 28 of 203
To mount the connection cap just insert the cap in the dedicated slots and apply light pressure on
