Becuase it will be gone forever as soon as you end the set. Click the right button to review the data for each subsequent rep in the set. Click the left button to review the data for each previous rep in the set.

Again this is something that all decent coaches have been doing for a long time. It should involve examining an athlete’s strength, power, athletic performance, flexibility, body type, explosive gifts, and mechanics, not just bar speed. And to be honest, the velocity at which you can bench or squat 20% of your max is not particularly valuable information; it’s not a good measure of explosiveness or strength. vbt chart You have to consider actual athletic movements and go beyond simply finding the slope of a load-velocity best fit line. Measuring bar speed offers a purely scientific, more formulaic method, but by itself it is inferior. Taken from Researchers González-Badillo and Sánchez-Medina paper Movement velocity as a measure of loading intensity in resistance training .Some more helpful charts/resources are below.

Absolute bar speed is not a programming lever

One particular shortcoming of VBT is that it does not address the quality of the movement. Mechanics are extremely important in strength training and must be taken into account in testing and workout regulation. With that in mind, if you are still in the process of mastering your lifts do not use VBT for your heavy strength training. Put a priority on perfecting the mechanics of your lift rather than bar speed.

That’s why I want to recommend a few beginner strategies that are easy to understand and will make a noticeable difference in your training. For your reference, I’ve included the in-app explanation of how to create a Force-Velocity Profile. Tap on the Tests tab, which is represented by the line chart icon. 1.) The circled items show the total fatigue endured for each set.

But if you run into a situation where you do experience ghost reps, just know that you can fix it by tweaking this filter accordingly. This will allow you to select which metrics you want to be overlaid on top of the video. Before you start recording, hit the plus icon (+) in the top right corner. In addition to that, it’s cool to post on your Instagram or other social media to share with your lifting friends.

Velocities on the bench differed so much from the squat and deadlift that the fixed velocity values did not apply. Everything stated above is based in the research, and is definitely a good place to start, but we encourage you to do more digging. We love sifting through data and research and providing educational content to you, but the best part of all of this is you can experiment with it too! You may notice there are general time assignments with each mesocycle. These are broken down further intomicrocycleswhich are shorter periods that can range from a few days to a few weeks and are the last major level of periodization.

It immediately gives you a concrete performance indicator for every rep so you can know how you’re doing and if you need to try to improve. Velocity – This is the feedback option I recommend for most people, most of the time. The strap is best if you’re attaching it to your body, such as around your wrist for a dumbbell exercise or securing it to a lifting belt or dip belt when doing pull ups or dips. The next step is to tether the encoder to the barbell with the string. You can do this with either the velcro strap or the roller hook. To do this, you’ll simply secure the Vitruve Encoder to a small metal weight plate using the built-in magnets on the bottom of the device.

Press the “End” button once you’ve finished your set. This will take you back to the training overview screen, which lays out all of the metrics for every rep within every set you perform for the current exercise. The main real-time metric shown by default is either mean propulsive velocity or mean velocity, depending on which one you set as your “Velocity Main Metric”. To change the “Velocity Main Metric”, go to the User tab. Then tap the settings icon on the top right and select either MPV or MV under the “Velocity Main Metric” option. I’ve kept my main real-time velocity metric as the default, which for me is the mean propulsive velocity; I find it’s generally the most meaningful metric.

For example, put a velocity requirement on an exercise/load and only count reps which meet the requirement. This ensures a level of quality, not just quantity of the repetitions. Put a velocity requirement on an exercise and continue increasing load until that requirement is not met. This is an alternative to percentage based loading that accounts for daily fluctuations in performance.

  • I’m sure there are times when you might only want to activate one or the other, there’s no issue with having both activated.
  • Powerlifters or other athletes who are serious about implementing VBT into their training and want a scientifically validated device to do it with.
  • The current trend is taking the concept of VBT and using it for strength and power training by measuring bar speed.
  • As I wrote in part one, speed-strength and strength-speed were never definitions of physical qualities or specific velocity zones.

It’s possible for your 1RM to change ≥10% higher or ≥10% lower than your “typical” 1RM. That’s a huge difference between your 1RM on your worst day vs on your best day. It wasn’t available when I first started using the Vitruve encoder. I find it to be a confusing name since there is also a “timer” feature, which functions more like a countdown – I’ll talk about the timer feature in the next section.

You can use the velcro strap to connect to the barbell, but it’s not nearly as convenient as the roller hook. Coaches can give the Vitruve Wellness Test to their athletes before a training session. Studies have shown that tests like this can provide accurate insights into the physical and mental state of athletes so adaptations can be made to their training ahead of time.

Even if you don’t use velocity tracking, lifters are always judging performance by how fast a lift felt. If you have a Vitruve device, it’s really very simple. During warm-up, which will be closely related to the exercise or movement that we want to measure, you will choose 4 loads, from a low load to a very high load. In this way, the application, through equations,will create your own personal curve and that when you perform ‘X’ exercise you will have your individual and exclusive percentage fully insured.

To view your progress, simply tap on the Progress tab, represented by the chart icon. The heavier the weight, the more accurate the 1RM estimation. For this reason, I recommend using your final warm up set to estimate your 1RM. The Force-Velocity Profile is an incredibly useful tool.

No problem, press the icon next the detected rep to remove it. Metric has thrown out the rulebook (again 😀) by using an all-new intelligent rep feature classifier that determines your actual rep start and end points. With this smart algorithm update your rep velocity and ROM data is more truthful and actionable than ever before, and Metric can now easily handle ballistic lifts. The Vitruve Encoder sports an impressive battery life of UP TO 25 hours.

Don’t lose sight of the training objective

It’s more efficient, since you achieve more with less volume and less time, although later we’ll delve into this concept.

This is where specific adaptations for a particular training cycle come into play. Think hypertrophy, strength, speed-strength etc. And this is where outfitting percentages or in our case, velocity, also comes into play in a big way . Also, since we have all spent plenty of time in the gym, we know that there are some days that you’ve got it and some days you don’t. Some days the weights feel light; some days they feel heavy.

Before this feature was implemented, there were several times when I performed a set that wasn’t recorded because I forgot to tap start. When I’m using the automations feature, this never happens. This feature makes it so you never have to tap start and/or end before and after every set. This gives you a big efficiency boost because you don’t have to fiddle with the app between sets.

So now there is a support card explaining why this happens. During every rep, the OLED screen on the encoder shows the Mean Propulsive Velocity, Peak Velocity, Range of Motion and rep count. It also shows the percentage of remaining battery life if you’re reviewing the reps after your set using the left and right physical buttons on the encoder.

By default, the ROM filter is set at 0.66 ft for every exercise. For most people and most exercises, this is a sufficient ROM filter. I’ve personally never had to modify it since I’ve never experienced any ghost reps. The range of motion filter lets you set the minimum amount of distance that the encoder string must travel before it records the movement as a rep. I haven’t had a real need to use it in my training. And I don’t recommend activating unless you have a reason.

Range of motion, limb length, coaching emphasis, training history, and genetics all impact the shape of an athlete’s profile at any given time. There is even the potential for a load velocity profile to change over time as an athlete becomes stronger, bigger or more powerful. Just like load velocity profiles will differ by movement pattern, no two athletes will have the same load velocity profile.
