G-Flight

The G-Flight is a portable jump performance measuring device. Using newtonian physics, machine processing and micro-sensor technology, we are able to provide coaches and athletes an easy to use device that allows for immediate, objective feedback.

The device can be purchased here

A detailed write up on the device can be accessed (internal validation) here

A user manual for the beta devices can be downloaded from  G-Flight User Manual (beta)

 

A review of why jump heights between devices may vary (reach versus displacement) can be downloaded here Time In Air (Pressure vs Beam)

Below are several images and videos of the device being used

Here is what the final version of the G-Flight will look like! It will be wireless and fit in the palm of your hand! It will display jump height in inches and centimeters, rsi and ground contact times! If you are interested in purchasing it, check out the link in my bio. For more info, shoot me a message! . Also wanted to use this post as a chance to thank everyone for all of the support. @exsurgo.us and I have set out on a mission to bring a new age of affordable and portable sports tech. Made by coaches for coaches, these devices are designed to be used day in and day not. We couldn't be where we are now without everyone's input, patience and willingness to hop on board. -Max and Greg @exsurgo.us @arcthirtyfour . . #trackandfield #sports performance #exercisescience #training #train #science #strengthandconditioning #strength #strengthtraining #strengthtrain #train #lift #weights #conjugate #powerlifting #weightlifting #cscs #exercisephysiology #squat #bench #deadlift #fitness #strengthcoach #strongbyscience #gflight

Things are really starting to come together for @elliotmunnelly This is another example of a lower body day emphasising force qualities. First little play about with the gFlight with barbell vertical jumps his highest jump of day was 25.15cm with 50% of his BW we’ll revisit it next week and try and beat that score 💪🏼 A lot of rain made it difficult to really project and attack the sprint from the start but we’ve been putting the focus on staying patient and gradually becoming upright. The sled helps him, but you can see things are starting to look smooth which is really nice to see 🤓 @primalhealthgym #teamprimal #primalgym #sledsprints #sprinting #jumping #broadjumps #verticaljumps #gFlight #force #velocity #athlete #power

A small chat with @strong_by_science prompted a Christmas Eve experiment after closing the gym. By placing the gFlight in between hurdles you can actually get a contact time if you go back and break the beam. So whats the value of this… You can get an idea of just how high a hurdle you could use to maintain a ‘plyometric contact’ like my video shows. If you had access to a couple of gFlights like some people will do, you could have one at the first contact and one at the end to measure fatigue through a rep/set. Finally, this isn’t just limited to hurdle hops. My last two videos show a broad jump variation and lateral hop variation where you could use the gFlight and a tape measure to see just how much difference it makes to a jump when you maintain a certain contact time. There’s jump variations there that ultimately every athlete should be exposed to but some might hold more value than others depending on the sport 🤓 @primalhealthgym @exsurgo.us @dg1_greg #primalgym #teamprimal #jumping #experiments #plyometrics #hurdles #gFlight #broadjumps #lateraljumps

Really enjoying putting the gFlight beta through its paces in the last week or so, thanks to @strong_by_science and @exsurgo.us for putting together a great bit of kit. Currently I am using it to monitor neuromuscular readiness on a daily basis. I have also been using it for biometric feedback providing percentage cutoffs for main lifts from monitoring jump height after every lift, as well jump pulls from the floor. Still collecting data at the moment but the results seem to be heading in the right direction. What makes this even better is the portability of the device as I can take it on flights so we can constantly monitor on the go. . . . . #strengthandconditioning #fitness #gym #strengthcoach #coach #mobility #stretching #weightlifting #squat #clean #jerk #snatch #sportscience #athlete #nofilter #athleticdevelopment #nutrition #exercise #motivation #muscle #power #speed #weights #tennis #rugby #sports #plyometrics #crossfit

I got this prototype yesterday and what better way to test it than with my strength and conditioning class for the seacoast United soccer team U11-12 boys and girls. This is only the 3rd session so we still learning proper body mechanics as you can see on the squat jump. We are learning how to land where we took off from. Now with the gflight I'm going to be able to asses every athlete and track their progress, now that we tested the timer for the first time since being built I can also start assessing distance. Amazing job @strong_by_science and @exsurgo.us for such an amazing product we are into something big here. • •highlights •26 tested athletes were tested • speed test, 40+- yard shuttle run • height tested with CMJ free arms •no errors with CMJ free arms •speed errors 6 due to foot position • fixed with cues • #ttraperformance #strengthandconditioning #soccer #winter #power #speed #squats #shuttlerun

We made the G-Flight so training can become more effective. We don't necessarily see it as a research tool, but more as a training tool! We want something that is easy to use and immediately actionable. How can it be used in training?? . . The video is an example of me using the G-Flight to help guide my power training session. I would perform an Olympic variant and then a jump. The G-Flight would provide Jump height and the decrease in jump height was used up determine whether or not I was fatigue. . . By doing this, I can get a better understanding of how the training loads are influencing my acute fatigue levels. At the same time, I get an objective measure to help motivate me and increase my intent. . . The G-Flight jump heights are shown on the right and I used a % drop in my jump height to determine if I was getting too fatigued. . . Not everyone has the money to afford a tendo unit, so having velocity and decrease in velocity % as a measure of fatigue is not possible. The G-Flight allows me to use it as a short cut for fatigue monitoring. Thanks to science, drop offs in jump height are related to lactate accumulation and fatigue. Measuring jump height lets me monitor my external and internal changes!

#Repost @exsurgo.us (@get_repost) ・・・ Working on finding a quick GCT. My jump is higher but the GCT was lower. When I focused on quicker GCT, my jump was not as high. Now the trick is keeping the GCT low and working on the jump height! Only way I could even begin to know and understand this is by talking with @strong_by_science and using the #gFlight to give me instant precise feedback. Just imagine what you could do?! #designer #producer #engineer #3dprinting #drones __________________________________________ #exsurgo #lacrosse #lax #soccer #futbol #trxtraining #trx #kettlebells #spartanrace #spartantraining #spartansgx #olympiclifts #usaweightlifting #uslacrosse #mls #nll #mll #nutrition #coachingkids #sportsnutrition #functionalmovement #loudouncounty __________________________________________
