Time for Anaerobics
As we said before, anaerobic means "without oxygen," meaning that the muscle cells convert their stored energy, or fuel, into movement by a chemical process that doesn't involve oxygen. This is necessary because it takes the heart and lungs time to catch up and trigger the aerobic process to take over the fuel delivery process. But in some sports, such as sprinting or weight lifting, the event is already over by the time that process kicks in.
In the past 30 years or so, aerobic exercise has been promoted heavily because of the way it protects the cardiovascular system from disease. All the publicity surrounding aerobic exercise may make it seem that anaerobic exercise is somehow not as beneficial, when in fact a good fitness program incorporates both kinds of exercise.
A lot of really fun sports are anaerobic exercise, or a mix of both anaerobic and aerobic exercise. We will now take some time to go over the variety of anaerobic exercises and sports available to you, so get ready. It might take more than the two minutes your muscles need before they switch to aerobic, but we promise it's worth it.
1. What is anaerobic ?
2. What's the advantage of sprinting or weigh lifting ?
3. Why the increase in popularity of anaerobic ?
4. Research a sport you would be interested in that is anaeobic- which sport and why did you choose it ?
In hockey, as in other anaerobic sports, quick bursts of energy are followed by brief rests.
Anaerobic exercise asks the body to put out its maximum effort for a fairly brief period of time. How brief, you may ask? In most sports, it's from 30 seconds to around 2 minutes. During that burst of exercise, your heart rate should hit 90–100% of its maximum heart rate. Then, after a brief rest — sometimes as little as two minutes — we ask the body to do it again.
People whose sports put them through repeated, high-intensity bursts of exercise need to be in great anaerobic shape. This means that their bodies have to be able to recover quickly and be ready to put out maximum effort again in short order.
When anaerobic athletes practice or work out, they spend most of their time working as hard as they can for a short stretch, then resting. By gradually increasing muscle strength, anaerobic athletes can put even more intensity into each burst of exercise. They can also train their bodies to recover more quickly and be ready to perform again.
Examples of Anaerobic Exercise
- Weight lifting
- Push-ups and sit-ups

Benefits of Anaerobic Exercise
It takes muscle to swing a bat.
The chief benefit of anaerobic exercise is strength. Each of the various forms of anaerobic exercise strengthens the muscles to one degree or another, although the muscles that get the strongest are the ones targeted by a specific exercise. Think of the bulging arms of some baseball players or the huge thigh muscles of hockey players.
However, that kind of muscle strength isn't the only or even the most desirable outcome of anaerobic training. Strong muscles — even if they aren't "bulging" — are one of the most important factors in good health and weight control. They also are a key component of looking and feeling your very best.
Anaerobic exercise promotes good health by:
- Improving posture and flexibility
- Strengthening bones
- Reducing blood pressure
- Boosting metabolism

Safe to Get Buff
Many people associate weight training with hugely muscular people, the kind we see on television participating in strength competitions. In recent history, however, weight training has passed into the arena of commonly performed exercises for people of all shapes and sizes, not just for those with bulging muscles. How do you feel about this type of exercise? Respond to at least one of the following questions.
- Is weight training for everyone? Why or why not?
- How can weight training enhance fitness and performance in other sports?
