Velocity Based Training

Resistance training is a key part of every workout program, regardless of your goals. It is important in weight loss, muscle gain, and explosive strength. The two main focuses of resistance training are Intensity and Volume.

Intensity is the amount of weight you are lifting, or your load, whereas volume is the number of repetitions and sets you complete. The balance between the intensity and the volume of your resistance training will depend on your goal. I have already covered weight training and reps in this Blog Post.
For any regime, you need to determine the proper intensity for that volume. Typically, this is down by determining your One Repetition Maximum (1RM). 1RM is the maximum weight you can lift properly once. Your 1RM should be tested for multiple lifts, since the weight will be different for each major muscle group. Once you’ve determined your 1RM, your program design will be based on a percentage of that weight, matched to that volume.
Science for Sport has an article explaining how to the 1RM test.

Downsides to keep in mind with the 1RM test method are:

• First time lifters may not have proper form to complete the test
• It is time consuming
• Your 1RM changes as you grow stronger, requiring frequent re-testing
• You 1RM can change on a daily basis depending on your fatigue and hormonal balance that day

An alternative to the 1RM method of resistance training is Velocity Based Training (VBT). Velocity based training uses technology to measure the movement velocity of a lift. For example, you could measure the speed it takes to press a bar from your chest to fully extended (a bench press). The resulting data would give you the movement velocity is m/s. Your maximum movement velocity is known as movement velocity threshold (MVT). In order to determine your MVT you should complete the same test as the 1RM but with your VBT gadget.

The benefits of VBT immediately counter the downsides of 1RM.

• You don’t need to complete the VBT test as often as the 1RM. You’ll notice the MVT is given in meters per second, not as a weight like the 1RM. What this means is that as you grow stronger and increase your weight, the speed at which you complete your maximum weight lift should remain the same.
• The MVT is easily adjustable for your daily training readiness (i.e. fatigue and other changes that affect your strength). When using the %1RM method, you are scheduled to lift 80% of your 1RM for that day. You load on the selected weight and complete your workout, but maybe don’t get as many repetitions before failure. With the %MVT method you can immediately see the inability to reach the desired velocity and adjust the weights to make your repetitions for that workout.

The downsides to MVT training are

• It is individual and exercise dependent, so more initial tests may be required
• The technology is pricey

Velocity based training paired with the improvements in technology is making it a more viable resistance training tool. It is a great tool to maximize workouts while allowing for day-to-day training fluctuations. Before jumping on the latest technology train make sure you check out the different devices and choose the one that is right for your workout. As always, make sure you have the basic movements of your workout down before adding in new technology, VBT is useless if you aren’t doing the lift correctly to begin with.
