  • … plot according to minimum force on (not elastic) / minimum displacement (elastic).
  • Force/displacement repetition criteria is defined on exercise creation and have a default on preferences window.
  • can be zoomed clicking with mouse.
  • Repetition number is exported with the rest of the data.
  • All the force sensor mode now uses database

  • Encoder configuration can manage multiple configurations. Configurations can be easily changed, imported and exported.
  • Added rest time after each test. And has an option to highlight (red) persons with rest time higher than a value. Persons can be sorted by rest time.
  • Adjustable threshold on capture multitest (jump/races tests). Eg. solve problems with persons who loses pressure with the platform while going down previous to a CMJ or ABK jump. There are three different thresholds: jumps, races, other tests.
  • Global changes:
  • Main interface has separated simple/reactive jumps and simple/intervallic races.

  • Encoder:
  • New capture method. Faster and works in all systems (old method didn't work on XP and has some problems on MacOSX).
  • On capture now realtime data on inertial machines is dispayed. Repetitions are shown as concentric or concentric-eccentric.
  • But, after capture, repetitions will be shown as concentric or ecc-con. This happens because all the software parts are not prepared yet to manage the con-ecc repetitions.
  • Results on realtime capture are now very similar to the results obtained at the end of capture.
  • Inertial machines with too much friction can use now the inertial momentum calculation method because now it needs only half of the oscillations than before.

  • While capturing now is not possible to press buttons like weight, laterality, ... changing this button on capture produces problems in previous version.
  • Fixed some bugs on loosing information on serie recalculation (video got lost). All the lost data has been recuperated.
  • Fixed a problem on saving 1RM when it couldn't be calculated.

  • Comments can be added to signals and curves using the "load signal", and "select curve" buttons.
  • Updated English manual.
  • Added Neuromuscular Profile Analysis. Instructions:
  • Configure capture "end at n inactivity seconds" to be greater than 10 seconds, eg: 20 seconds.
  • Perform 6 CMJ jumps resting 10 seconds between each jump. 4 phases will be registered for each jump: eccentric, concentric (jump), eccentric (reception), concentric (return).

New in Chronojump 1.4.0 (Mar 11, 2014)

  • Encoder: Added configurations for different encoders: linear, rotary friction and rotary axis; and machines, like inertial machines.
  • Encoder: Added automatic inertia momentum calculation method.
  • Encoder: show realtime bars on capture on main window. Colors and sounds are also implemented.
  • Encoder: Added RDotNet to have realtime statistical calculations.
  • Encoder: CSV export can select latin: 2,3; 2,4 or non-latin 2.3, 2.4 (see preferences).
  • Encoder: lots of improvements on calculations: better, faster.
  • Encoder: capture ends automatically when no movement. Also fixed problems when pressing "Finish" button.
  • Contacts: Fixed some crashes on executing tests caused by database writing specially on runs.
  • Contacts: Added run interval tests: T Test, 3L3R.
  • Contacts: Better info on simulated tests.
  • If Chronojump is old for database, shows database folder.
  • Lots of improvements on graphical interface.
  • Translated more than 75% of strings to: Czech 99%, Spanish 98%, Slovenian 98%, Greek 98%, Deutsch 88%, French 85%, Gaelican 84%, Brazilian Portuguese 79%, Catalan 78%.
  • Translations work perfectly on Linux, and on most of the windows machines, we are working on fixing all transtations.
  • Updated authors file.

New in Chronojump 1.3.9 (Jun 21, 2013)

  • boot lot faster (deactivated server connection).
  • Encoder: 1RM prediction using speed/load on any exercise. Uses the speed 1RM values defined for any exercise. It's on analyze / cross variables / last option. 1RM is predicted using the values on preferences: The "^3" means that the right part of the graph (more load) are the most important values on the regression, while the "non-weighted" means that all the points have the same importance in the regression. We recommend the "^2".
  • Encoder: On selecting an extra load, it's shown the %1RM (if it has been calculated before for that person, exercise and session). Also it's shown the displaced mass: extra weight + (body weight * % body weight displaced on that exercise).
  • Encoder: the analysis data table shows the extra mass and the displaced mass.
  • Encoder: Improved the external capture to make it's data match with the data shown after on Chronojump. It was difficult because capture shows real time, and this makes the curves "cut" and smooth different than the consequent analysis that has all the curves and makes new cuts. Now the information on external capture is more accurate.
  • Encoder: Invert mode for capture is allowed. Have the encoder upside-down.
  • Encoder: The external capture records video.
  • Encoder: improvements on graphical interface. Some users after capture modify some controls to do another capture (eg: increase weight button), but before new capture, they remember to save curves (curves then got recorded with new controls (that were not the used in capture). It has been fixed, now a signal or curve is saved with the controls when it has been captures, recalculated or loaded. sorry for this fuzzy explanation but believe us: now is more difficult to have user errors with the interface.
  • Encoder: Graph on analysis window has some displacement controls that allows Chronojump to be resized down once graph is done for a certain resolution.
  • USB-Serial ports for MacOSX. Mac native version is coming.
  • Changed software logo: Kangaroo.
  • Translations. welcome to new Greek (98%) translation. Updated Spanish (100%) and Czech (99%). improved an script to compile Deutsch, Czech, Slovene, Gaelic and Greek.
