Anaerobic Exercise - Pushing Your Limits
Anaerobic Exercise - Pushing Your LimitsBy Greg McKenzie
Anaerobic exercise is where the body is exercising at such a rate that the blood stream cannot supply oxygen to muscles fast enough.
Anaerobic exercise is essentially exercise without oxygen. This happens during high intensity and cannot be held for long periods of time. A product of your muscle exercising in an oxygen deprived environment is large amounts of lactic Acid. Lactic acid begins building up inside the muscle at a rate faster than it can be cleared creating muscle failure.
Anaerobic exercise does not refer to respiration as a whole, however rather to anaerobic muscle respiration. The muscle will still get oxygen, however it will not be sufficient to meet the activity's demands. Anaerobic threshold or lactate threshold are terms for anaerobic capacity. It is the stage in anaerobic exercise where lactic acid forms in the muscle at a rate faster than the rate at which it can be shed by the muscle.
This is considered the greatest measure of an athlete's physical shape. An athlete that has a higher VO2Max is typically consider fitter, yet an athlete with a lower VO2Max and higher anaerobic threshold can gomuch further faster without muscle failure than an athlete with high VO2Max and a low anaerobic threshold.
One thing that can genuinely improve your anaerobic threshold is training. Great anaerobic sports include basketball, football, rugby, hockey and soccer. Anaerobic sport is when you do spurts of high intensity exercise. Weight lifting and interval training are examples of anaerobic workouts.
Exercises that bring and hold you above your anaerobic threshold for longer amounts of time can actually improve your anaerobic threshold. The High Intensity Interval training (HIIT) exercise routine can achieve this. HIIT allows you to spend a long cumulative time in an anaerobic state by alternating high intensity activities with periods of rest and recovery.

,What is the Difference Between Between Aerobic and Anaerobic Exercise
What is the Difference Between Aerobic and Anaerobic ExerciseBy Adrian Jenkinson
Literally, aerobic means "with oxygen" and anaerobic means "without oxygen." Immediately we're heading towards the realms of confusion; how is it possible to exercise without oxygen? It's not - the definition refers to the way in which your body gets its energy while exercising.
In the case of aerobic exercise, these are activities that can be performed over an extended period of time without muscles experiencing burn, examples are walking, slow swimming and sedate cycling. The fact that there is no significant muscle fatigue during the course of these exercises does not mean that they are useless in terms of increasing fitness and losing weight. Aerobic exercise is performed over extended time periods which means that the muscles endure a sustained workout, which in turn results in calorie burn and increased muscle tone.
By contrast, anaerobic exercises are explosive short term activities that result in muscle fatigue triggered by lactic acid. During the course of the exercise the body has no time to gain energy through the normal channel of absorbing oxygen, it goes for a quick hit of sugar-based energy directly from the bloodstream.
Again, anaerobic exercises are just as viable as aerobic exercises, because the muscles will grow in order to cope with the task better the next time it is performed. While they are growing they are absorbing energy, thus helping you to lose weight even while you sleep.
A sprint performed at top speed or an intensive set of crunches are both examples of anaerobic exercise, the explosive nature of the exercises means that you cannot sustain them for any significant duration, if you tried you would probably collapse through exhaustion.
Sometimes the line between aerobic and anaerobic exercise is blurred. Taking our earlier example of walking, which is clearly aerobic, what if you were to increase your pace and carry a heavy weight at the same time? It would not be long before you needed a rest, thus illustrating that the exercise has now crossed the line and become anaerobic.
Aerobic
With oxygen No muscle burn Walking Slow swimming Gentle cycling Yoga Anaerobic Without oxygen Uses blood sugar Quick muscle burn Sprint Bench press Pull ups Push ups Whether your chosen exercise is aerobic or anaerobic, as ever the key to successful exercise is to perform it regularly, daily if possible, incorporating it in to your lifestyle as a permanent feature. This is how the advantages of your exercise - whether it's weight loss, general fitness or both - will become permanent too.Visit our website to learn about Exercises To Lose Inches We're here to help!
,Anaerobic Exercise Vs Aerobic Exercise - Which is Better For You?
Anaerobic Exercise Vs Aerobic Exercise - Which is Better For You?By Shin Ohtake
When it comes to promoting weight loss and cardiovascular health, just about everyone thinks of aerobic exercise as being the solution. While it may be the more chic / stylish / trendy / hip / cool and obvious choice, it isn't necessarily the greatest solution. Anaerobic exercise on the other hand, has incredible benefits that are often overlooked.
Let's first clarify aerobic and anaerobic in terms of it's dependence on oxygen. We, as organisms, require oxygen at all times. Although aerobic is considered oxygen dependent and anaerobic non-oxygen dependent, this is only in molecular terms. Whether you're doing wind sprints or running a marathon, as an organism you are breathing and utilizing oxygen all the time.
Oxygen only becomes a variable among the different energy pathways. Therefore, exercises that are considered aerobic in nature such as running or biking at low to moderate intensities for long durations, get their energy predominantly from oxygen dependent energy pathways. Whereas exercises that are considered anaerobic in nature such as weight lifting and sprints that are shorter in duration and higher in intensity, get their energy predominantly from non-oxygen dependent pathways.
Since aerobic exercises are considered to be beneficial for cardiovascular health, people tend to pick activities that are low to moderate in intensity however longer in duration over doing activities that are higher in intensity however much shorter in duration. Hence the aerobic vs. anaerobic battle. In actuality, activities that are considered aerobic or anaerobic are not that different in terms of energy. Activities requiring different energy pathways are briefly explained as follows:
- Activities that are very high in intensity that require a lot of energy very quickly, utilize the phosphagen energy pathway. This energy pathway is not oxygen dependent. It provides energy very quickly, however only for a short duration. This is because it derives energy from an energy rich element called "phosphates" that are stored in the skeletal muscles in very limited quantity. Because of its limited supply, phosphate gets depleted very quickly (10 seconds or less). However, in about 5 min almost all of the phosphate will be replenished and stored back into the skeletal muscles.
- Activities that are high in intensity and longer in duration (up to 2 min), utilize the glycolytic energy pathway. The glycolytic energy pathway uses glucose stored as glycogen in our body as it's source of energy. This energy pathway operates in the absence of oxygen and converts glucose to energy, however also produces lactic acid as a nasty by-product. At this intensity the human body cannot metabolize or get rid of lactic acid as fast and as fast and as quickly as it's being produced. The lactic acid accumulates and wreaks havoc on skeletal muscles, deteriorating its ability to do work. This is known as the lactic threshold or the anaerobic threshold.
- Activities that are light to moderate in intensity and longer than 2 minutes in duration utilize the oxidative energy pathway. This energy pathway is oxygen dependent.Similar to the glycolytic energy pathway, it uses glucose in our bodies as it's source of energy. However, this pathway converts glucose into pyruvate which enters the Krebs cycle. The Krebs cycle is very efficient and yields more and greater energy from glucose without producing lactic acid as a by-products. Therefore, more and greater energy is produced as demanded by activities with longer durations. This energy pathway can also use fat or adipose tissue as an energy source at suitable low intensities. However, the process is very slow and inefficient, especially and particulary in terms of performance.
