Sprint Training and Skating Starts
In order to improve performance. all athletes should be focusing their training to specifically enhance motions utilized in their sport or competition. With regards to Short Track Speed Skating, race times are heavily affected by a skaters start. Ice skating sprints starts have a similar motion and acceleration as dry land sprint starts. It is therefore surmised that training dry land starts will benefit on ice starts. Researchers from Australia worked with nine elite and trained short track speed skaters utilizing a four week dry land starts training program to test on ice start improvement.
Athletes completed both dry land and on ice sprints to gain a control number followed by specific sprint start training and then re-doing the dry land and on ice sprints. Figure 3 below shows a comparison of an athlete’s dry land sprint time, to on ice sprint time. Both sprints were measured at time to cross 14.43m. The open circles and dashed line show the results during the control period and the black circles and solid line show the results after specific training.
The results showed a 2.6% increase in on ice sprint time after specific dry land start training.
This information can be extrapolated to all athletes. The results show that targeted training of a specific sport mechanic improve results in a game setting. An argument can be made that on ice start training will have equal or better results than dry land start training. While this is likely the case, training in the sport environment, with the right equipment, or having the right number of other athletes is not always possible. In the example of short track speed skating, the athletes likely don’t have ice access during every training session.
The take away for you as an athlete it to work with your coach or personal trainer and determine specific movements and motions you want to improve. Create a training program that you can do anywhere, especially days you don’t have access to play simulation, to target your goals.

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