One personal anecdote I’d like to add is that one time I accidentally left the string attached to my barbell after finishing my workout. I was startled when this happened and was afraid I might have damaged something. But the string and the encoder shell were completely fine. I noticed that there was a small rubber ball affixed to the start of the string, which is designed to absorb impact and prevent damage in this scenario.
The strength speed spectrum is determined by higher power outputs than the max strength zone, but majority of the contribution comes from the load on the bar and not the speed of the movement. Loads range from roughly below 80% – above 60% of one rep max with corresponding velocities of roughly above 0.6m/s and below 0.9m/s. The velocity zones provided athletes with a goal to focus on when additional weight on the bar was no longer desirable. Use improvements in velocity as an indicator for increases in strength. An improvement of 0.04m/s for your best rep on any given load above 70% of 1RM is equivalent to about a 5% increase in your 1RM.
In this article, mean velocities will be discussed. This is because mean velocities are more stable measures for most exercises due to the large amount of time that is actually spent decelerating the bar . Overall, the traits developed utilizing Velocity Based Training concentrically with average velocity can be categorised into different velocity zones.
Often, lifters will unknowingly perform more reps and/or sets than is necessary for their training goals. The extra volume doesn’t provide an additional benefit. Rather, it only adds fatigue, which increases recovery time within and between workouts. You can use Vitruve to manage fatigue by setting velocity loss thresholds within and between your sets.
Truth is the training process needs to be a science AND an art. First I want to point out that most explosive training naturally provides velocity feedback, which is used the same way as bar speed data, even if velocity is not the thing being measured. For example, if you time a sprint or an agility drill, you are vbt chart indirectly measuring velocity. That measurement can be used to regulate volume in a workout. And if you’re a speed athlete, I certainly hope that your speed performance is factored into your force-velocity profile. If you get feedback on the height or distance, you are indirectly getting feedback on velocity.

The key is to realize who the exceptions are and why they are occurring and not to disregard the rules. Video data overlay and easy sharing Metric now has a visualisation of your data placed on your lift video. This can help you understand how each rep looks and relate it back to your velocity. With the addition of a share button its now even easier to post your lifts to social, or quickly send them to your coach. Metric is now able to record sets reliably from a wider range of phone positions, including placing the phone lower down relative to the barbell. Metric now provides simple training context information that helps you determine how well you are lifting.
Increase your work set loads on days when your predicted performance level is higher. Any time we get feedback on the speed of a sprint or the height or distance of a jump or throw, that is velocity based testing. There are all kinds of options across the strength-speed spectrum, from top speed timing to max strength testing. Measuring velocity on a barbell is perfectly fine but not a necessity.
MINIMUM VELOCITY THRESHOLDS
You can use it for multiple workouts before having to charge it back up. However, you need to understand that the battery uses more juice during reps. So it will drain faster, the more reps and sets you do. The profiles for these lifts are based on averages from studies. Other exercises in the app have much less accurate default equations.
Bar speed is a consequence of our programming, not a lever to pull for chasing specific adaptations. Its products include e-transformation applications, energy and infrastructure applications, public applications, commercial applictaions, application modernization, and BMC software. The firm services also comprises outsource, education, consultancy, and modernization services. The company was founded by Ayten Ezentes and Ipek Canan Basaran on June 24, 1993 and is headquartered in Istanbul, Turkey.
Interestingly, every month and a half approximately we reevalue our velocity profile to adjust loads. The increase in fidelity with version 0.2.0 exposed a skew in Metric’s measurement of fast movements where bar speed exceeded ~0.8m/s mean velocity. This update removes this skew at faster velocity, further improving Metric’s validity and correlation to MOCAP reference data. Users may see notable change to their reported velocity for fast reps. Training with a focus on maximum intentional velocity (i.e. lifting as fast as possible). Once you complete each of the 4 records/test sets, it will show your estimated 1RM at the bottom.
“Strength Qualities”
Metric now holds onto your set data right up until you actually record your next set. Leaving the Set Review screen will not delete this data. When video was being reprocessed for accuracy, sometimes results would be wildly inaccurate. The culprit was memory handling; Metric now handles memory properly so more accurate results are in fact more accurate.
You can modify them if/as needed at any time while training. This is a completely legitimate reason to measure bar speed on strength exercises, but it should only be done with experienced lifters. For all of your deadlift sets in today’s workout, try to beat your best rep mean velocity from last session. This will encourage you to lift with more intent and compete with your former self.
You can activate the video mode after you enter your set weight and hit the “Start” button to begin your set. Once on the next screen, simply tap the camera icon in the top right corner. Once you select the exercise that you want to do , the next screen will allow you to input the amount of weight you’ll be lifting for your first set. Go to the training tab, which is represented by the icon of a lifter pressing a barbell overhead. Position the anchored encoder directly beneath where the bar path will be during the exercise.
- Most of us need maximum strength training to keep progressing over time.
- The ability to manage multiple athletes, which is a must for most coaches.
- This is an important distinction since there are some differences between the iOS version and the Android version.
- VBT is using velocity feedback to influence workouts.
Since velocity zones are variable given the exercise in question, and the training age of the athlete, among other factors, the following is to be taken with a grain of salt. It is not written in stone, and is subject to change within variables. The two charts do not necessarily agree either, which is why we wanted to give both. They are adapted from Bryan Mann’s book in addition to research cited below and will be a good starting point to help you with understanding percentages and VBT. The only true way to understand this is to try it yourself and with various teams to help you build your own profiles for athletes with more precision. For example, the fatigue is expressed in relative terms (i.e. as a percentage), whereas velocity zones are set using absolute velocities.
Is the Vitruve Encoder worth it?
If you don’t get a very high R² value, it’s probably because you weren’t warmed up, had bad technique, chose the wrong weights or didn’t lift as fast as possible for all sets. Once you’ve selected the metrics you want to be displayed, set up your phone or tablet so that you’re in the frame, or have someone else film you. Don’t forget to hit the record button before starting the exercise. All of your data will still go into the training overview table when you’re using the video recording feature.
If you drop below the lower limit before completing the desired number of repetitions, that’s a sign you should reduce the weight. Then tap the ‘plus’ (+) in the top right corner. This will give you a list of around 100 additional exercises to choose from .
In that case, you’ll get an additional bulk discount per unit depending on how many your order. You save $19.65 compared to if you bought the roller hook and magnetic phone mount separately. Velcro strap to connect the string to the barbell or your body. We have to train at all different velocities in order to “optimally develop force production abilities” or something like that. Returns OHLCVDFAccessor._metrics, which gets copied upon creation of each instance.
This gives you instant visual feedback for each rep when using the app. The Vitruve app tracks your progress over time for each lift. The Vitruve encoder can easily be transported in your gym bag. The time it takes to set it up – from taking it out of your gym bag to anchoring it and connecting the string to your bar – is just a few seconds. People have made up these “strength qualities” and convinced themselves that each one has to be trained individually, and that is just not the case. Train speed the best way possible and train strength the best way possible.

Of course, you won’t see this since you’ll be lifting. You can tap on any training session to see the workout history. It will show all of the sets, reps and velocity data for that session. Let’s say you’re still getting unrealistic 1RM estimates https://cryptolisting.org/ even when going very heavy and you have an “almost perfect equation” for your profile. In this case, you may need to re-do your profile – but this time, you’ll have to manually enter a minimum velocity after completing your 4 records/test sets.
This is not hard to do, I am working on an explainer article on this topic . And while generalised velocity based training has been shown to be a more effective programming strategy than % based training , the use of individualised velocity data is even more effective. Dorrell showed this in another of his 2020 studies when he compared autoregulated training using a group VBT approach vs individualised profiling and load adjustments. While the shape of each load velocity profile and slope of the lines are similar, the absolute velocities achieved at each load are hugely variable. He specifically comments that excluding the bench press from the data set had to be done to make the zones possible.
Speed-strength is the next trait and includes velocities ranging from about 1.0 to 1.3 meters per second, depending on the amplitude of motion (4-6). The Olympic lifts may have a much higher velocity as the bar has to move much farther. Speed-strength can be best defined as speed in conditions of strength, or speed being the first priority and strength being the second. In essence, it is utilizing lighter loads at very fast velocities. Over the past several years, Velocity Based Training has been coming to the forefront as an innovative way to determine load for strength training.
