It lasts about 20 to 30 minutes, inducing both aerobic and anaerobic physiological adaptations 9. At this same intensity, an interval training approach may be utilized that consists of a series of short working episodes separated by brief recovery bouts.
For example, a cyclist may choose to sprint a distance the length of one city block and coast the next block, continuing in a cyclical fashion. Interval training has become very popular as a time-efficient training strategy for aerobic endurance athletes. Interval training involves intensities at or above VO 2 max, typically lasting between 30 seconds and 5 minutes For an aerobic endurance athlete, the rest times between intervals are typically equal to or less than the work time itself, which keeps the work-to-rest ratio at or The primary benefit of interval training comes from the increased volume of training at intensities that otherwise could not be sustained for prolonged periods of time.
Much research has been devoted to the short-term and chronic benefits of interval training 15, Similar to traditional aerobic endurance training, interval training can result in improvements in cardiorespiratory and cardiovascular fitness, blood volume, LT, and muscle-buffering capacity These factors are necessary for improving performance and are similar to those adaptations seen with LSD training.
Therefore, if similar adaptations in aerobic endurance performance can be achieved using interval training for 20 minutes versus LSD training for 45 to 60 minutes, then interval training is clearly more efficient.
It also results in less stress on the body Research supporting the implementation of resistance training in an aerobic endurance training program has expanded as an efficacious strategy for preventing injury and increasing strength, power i. At a certain point, you can't breathe any faster and your body starts to slow down. Read more: Definition of Aerobic Fitness. Distinct from your aerobic energy system is the anaerobic system. As your workout gets more intense your aerobic energy system simply can't power your muscles.
The aerobic system is good for slow and steady exercises like long-distance jogging or swimming, but when you need short, fast and intense effort — such as sprinting to first base or squatting a super heavy weight — the aerobic system can't keep up.
The anaerobic energy system is what you use during intense activities like a sprint or vertical jump. It's more powerful and lets your muscles work faster, but you run out of this type of energy much faster.
It might seem like the best aerobic workout would be slow and steady, since that's when you're primarily using your aerobic energy system. However, the best aerobic workouts may actually be interval workouts that alternate between aerobic and anaerobic work, such as sprints. Interval workouts can give you the same benefits as aerobic exercise. A research review from the Gatorade Sports Science Institute found that over two weeks, three interval workouts per week showed benefits that you would typically see from endurance training.
Similar to endurance training, interval training makes your heart more efficient. You increase the amount of blood that you can pump, which provides your body with more oxygen.
Your muscles also become more efficient. They can process more glucose and fat to create energy. And finally, cardiorespiratory training improves the ability to both move oxygen and nutrients to working muscles and to remove metabolic waste, which allows muscles to continue to perform a particular activity.
Every person starting a workout program will have a unique goal, but each goal requires a different level of focus on each of these components. A well-designed exercise program includes all three components. And if your client is participating in a race or wants to lose weight, you would emphasize cardiorespiratory training. While cardio training is most often associated with fat loss, it is also the best way to improve aerobic capacity, which is the ability to use oxygen to fuel exercise activity.
During low- to moderate-intensity exercise, muscles rely on energy from a combination of oxygen and the substrates of carbohydrates in the form of glycogen , and fats called free fatty acids. The more oxygen that can be consumed, the more physical work an individual will be able to do.
And, because the body burns about 5 calories of energy to consume 1 liter of oxygen, increasing aerobic capacity can help the body become more efficient at using oxygen. This, in turn, helps burn calories, which an important component of weight loss. For strength-related goals, enhancing aerobic capacity can improve blood, oxygen and nutrient flow to working muscles and help with recovery between sets of resistance-training exercises. Improving the flow of blood to muscles can also help improve flexibility.
For weight-loss or endurance-training goals, improving aerobic capacity is essential for achieving them. Master the science of nutrition and the art of behavior change coaching.

Even small levels of dehydration can make it harder to push yourself. The NHS recommend drinking a minimum of 1. Taking hydration drinks before and during exercise will ensure you stay hydrated and replace lost electrolytes to fight off fatigue for optimal endurance performance. Read more about hydration strategies for running and cycling here. To improve your aerobic endurance and cardiorespiratory fitness, aim for between three and five sessions of aerobic exercise per week.
Mix up your training so hard days are followed by easier workouts to avoid placing too much stress on your system and give your body that crucial time to adapt. Limit harder sessions and HIIT workouts to one or two a week. The duration of your workouts also depends on your goals, current level of fitness, type of workout and other factors such as genetics. But there are some handy benchmarks.
Most studies show that cardiovascular training requires a minimum of 30 minutes, three times a week to guarantee increased aerobic capacity and you should see results within about eight to 12 weeks.
Consistency is the real key to seeing progress so follow a training plan that builds up your workouts sensibly, or work with a coach to devise a schedule specifically for you. This gives your heart, lungs, muscles and joints time to grow in strength and get used to the stress being placed on them. Think of it like building a wall.
