How can interval training be used

DO incorporate this type of training at least three times a week. DO warm-up before and cool down after your workout to allow your muscles to adjust accordingly and prevent any injuries.

This type of training is intense and requires an adequate recovery period. Try eating a banana an hour before. Fitness About Us. All Rights Reserved. Privacy Policy. COVID club capacity real-time tracker.

You'll be more time efficient. Many people don't exercise because they say they don't have time. The Department of Health and Human Services recommends minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or a combination of moderate and vigorous activity.

Interval training enables you to complete an effective workout in less time than a standard cardiovascular workout. For example, you might complete a workout in about 15 to 20 minutes or less instead of 40 minutes. You'll improve your aerobic capacity.

As your cardiovascular fitness improves, you'll be able to exercise longer or with more intensity. Imagine finishing your minute walk in 45 minutes — or the additional calories you'll burn by keeping up the pace for the full 60 minutes. Improving your cardiovascular fitness can also help reduce your risk of heart disease, high blood pressure and diabetes.

Yes — but you can take interval training to many levels. If you simply want to vary your exercise routine, you can determine the length and speed of each high-intensity interval based on how you feel that day. After warming up for a few minutes, you might increase the intensity for 30 seconds and then resume your normal pace. Finish with a cool-down. How much you pick up the pace, how often and for how long is up to you.

If you're working toward a specific fitness goal, you may want to take a more scientific approach. A personal trainer or other expert can help you time the intensity and duration of your intervals — which may include movement patterns similar to those you'll use during your sport or activity. The trainer may time the intervals based on factors such as your target heart rate and the ability of your heart and lungs to deliver oxygen to your muscles peak oxygen intake.

Interval training isn't appropriate for everyone. If you have a chronic health condition or haven't been exercising regularly, consult your doctor before trying any type of interval training. But it may be appropriate for people who are older, less active or overweight.

Studies suggest that interval training can be safe and beneficial even in people with heart disease and type 2 diabetes. Also keep the risk of overuse injury in mind. If you rush into a strenuous workout before your body is ready, you may injure your muscles, tendons or bones. Select personalised content. Create a personalised content profile.

Interval training combines short, high-intensity bursts of speed, with slow, recovery phases, repeated during one exercise session. An early form of interval training, fartlek a Swedish term meaning "speed play" was casual and unstructured.

A runner would simply increase and decrease pace at will. Today, athletes use more structured interval training workouts and high-intensity interval training HIIT to build speed and endurance.

This variation of interval training and speed work can be a simple or sophisticated routine, but the basics are still the same as the original fartlek training.

Interval training is built upon alternating short, high-intensity bursts of speed with slower, recovery phases throughout a single workout. Interval workouts can be highly sophisticated and structured training that is designed for an athlete based on their sport, event, and current level of conditioning.

An interval training workout may even be designed based upon the results of anaerobic threshold testing AT that includes measuring the blood lactate of an athlete during intense exercise. But less formal interval training is still beneficial for average people who aren't competitive athletes. Interval training works both the aerobic and the anaerobic system. During the high-intensity efforts, the anaerobic system uses the energy stored in the muscles glycogen for short bursts of activity.

Breaking into a jog, we use more still. As exercise intensity increases, so does the use of oxygen, and the relationship between the two has been shown to be linear. At fairly high intensities, fast running, for example, energy will also be produced anaerobically, but the oxygen use will still increase until it reaches its limit at the VO2max.

From then on, any further increases in exercise intensity will be fuelled by anaerobic sources. However, it is possible to predict a theoretical amount of oxygen required to work higher than the VO2max by extrapolating from the linear relationship between intensity and oxygen to intensity levels about the VO2max.

The difference between the theoretical level and the actual maximum must represent the anaerobic energy demands. This anaerobic demand is expressed as an oxygen equivalent. This is the method Tabata and colleagues used to measure the anaerobic demands of exercise. They are among the first researchers to employ this technique, so their findings from this study are very useful and informative.

Tabata and his team used nine undergraduate sportsmen as their subjects. The exercise was performed on a a static bike, which enabled the exercise intensity, in Watts, to be easily controlled. This was done so they could predict the theoretical oxygen demands at intensities above VO2max. The anaerobic capacity was obtained from the accumulated oxygen deficit during a high-intensity minute exhaustive exercise bout. The accumulated oxygen deficit in one bout is the difference between the predicted oxygen demand in ml of O2 per kg and the actual ml of O2 per kg used.

On a different day the subjects performed two different kinds of interval workout. The subjects performed six or seven bouts each until reaching exhaustion, ie, they could no longer continue at the prescribed intensity. The subjects managed four or five of these bouts. The oxygen used was measured directly as usual to give the aerobic demands of the interval sessions. The anaerobic demands were calculated as the accumulated oxygen deficit.

The accumulated oxygen deficit for bouts with rest intervals is the difference between the theoretical oxygen demand of the bouts and the actual oxygen used during both the bouts and the rest periods.

This means that on the I1 workout the subjects had reached their anaerobic capacity.
