Exercise that is just above or below the anaerobic threshold (AT) is known as aerobic exercise. Athletes must transition from aerobic metabolism to anaerobic metabolism at this time. An anaerobic threshold is a valuable tool for determining exercise intensity during training and competition in endurance sports.
Your body uses oxygen to burn lipids and carbs for energy during aerobic metabolism. It also results in the production of CO2 and H2O as the byproducts (sweating and exhaling). Aerobic mechanism powers the majority of what we do daily.
When you dramatically raise the body’s need for energy during activity and the aerobic system cannot keep up, anaerobic metabolism begins to take over. We now cross the AT at this location. The body uses stored glucose to generate the extra energy required during anaerobic metabolism. There is a quick creation of lactic acid more than the body can break down. Anaerobic power consumption is difficult to maintain for more than some minutes due to muscle soreness, burning, and exhaustion.
How to measure anaerobic threshold?
- Use a treadmill, bike, or elliptical to get your heart rate up for 3 minutes before you begin your race. Before moving on to step 2, completely halt and exit the exercise equipment for 30 seconds.
- Over ten minutes, gradually raise your intensity while paying great attention to your feelings. Continue until you can only speak short bursts of words before your breathing becomes labored.
- Take a ten-second pulse check after stopping your exercise. That figure can be multiplied by six to get a rough idea of your AT. Take a 10-second counting example to find your AT’s rate of about 150 beats per minute (25 x 6).
Why is anaerobic threshold important?
One essential training change an athlete could make is utilizing lactate as muscle energy. It is essential for both cardiovascular and stamina performance. To the fullest extent possible, your anaerobic system must be powerful and robust.
Enhancing your body’s ability to eliminate lactate is a secondary goal after reaching your aerobic threshold and minimizing its production.
Imagine your circulatory system as a vacuum that collects all the lactate for the most accurate approach to understanding it. The vacuum increases in size as the aerobic threshold rises. The greater the vacuum’s holding power, the higher the body’s anaerobic system will be able to assist in the process of creating energy. It is the reason why irrespective of how intense the exercise you perform, you will never be able to fully utilize your cardiovascular capacity until you have fully developed your aerobic threshold.
Simply put, you cannot contain all the lactate your body creates in your vacuum. It’s comparable to installing a V8 engine in a smart vehicle. Pairing the growth of the anaerobic and aerobic thresholds is the secret to achieving maximum cardiovascular growth.
It is what distinguishes this sort of training as an art. It goes beyond science. It varies from athlete to athlete or person to person. While boosting the anaerobic threshold necessitates intense exercise, raising the aerobic threshold demands a significant amount of low-intensity activity.
The most important lesson is that you don’t need as much anaerobic threshold training as you might imagine. Common athletes over 30 should focus at least 90% of their annual training volume on aerobic threshold exercises. Maximizing your cardiovascular ability requires only 10% of your annual fitness regime to be anaerobic.
How to improve anaerobic threshold?
Any short, intense exercise session that calls for quick surges of power and effort will activate the anaerobic system and increase endurance. Ensure to introduce these exercises gradually to your beginner and intermediate customers. Anaerobic exercise is difficult and demanding. Make sure clients are in decent aerobic shape before starting these exercises as slowly as needed.
One need not be a 100-meter runner to sprint. Changing the composition of your muscles and improving your anaerobic fitness can be done in entertaining ways. Running at full speed without stopping for a breath is the only way to get a true anaerobic exercise. Consequently, sprint intervals will require relatively small distances.
An excellent anaerobic workout involves sprints of 50, 100, or 200 meters interspersed with walking or jogging recoveries if you’ve access to a track. It’s also a good idea to perform hill sprints outside to vary this type of exercise. Beginning customers should begin with fewer repetitions and shorter distances.
2. HIIT Workouts
High-intensity interval training is sprinting that you can do. Use any sort of cardiovascular activity in a HIIT style for an anaerobic exercise whenever your customers don’t like jogging or whenever you plan to provide more diversity.
Experts recommend that you perform each exercise for 10–15 seconds at 90% of maximal heart rate, then 30–60 seconds of recovery. Running, rowing and cycling are all effective HIIT workouts.
People do plyometric exercises to increase power. But, it could also be an excellent anaerobic exercise. High-intensity plyometric exercises that raise the heart rate to 80 or 90% of its maximum can also get classified as HIIT exercises.
Jump roping is an excellent way to introduce plyometric exercises to new customers. It is a fantastic technique to begin exercising the body. It is also great for training the bones for the landings and jumps required in plyometrics. It can help hone coordination to prevent injuries. You can use the following plyometric exercises in a challenging anaerobic workout:
- Jumping squats: Begin with a small number. Then, give the first-time customers a brief break between each jump. Do more jumps with a pause in between for more experienced customers.
- Lunge jumps: Lunge jumps are a little more challenging, but not much. You should introduce lunge jumps to your clients after jumping squats.
- Box jumps: Use the box for customers who are in the middle or advanced level. It’s possible to progress from lower to higher boxes by repeatedly leaping onto them, then off them, and back onto them. To advance, add one-leg hops.
- Low barriers: Jump over a succession of low hurdles, increasing the time between each jump until there is none. Additionally, you can perform lateral jumps using the low hurdles.
4. Weight Lifting
All of your customers should frequently engage in strength training. Although, there are several crucial things to consider to turn lifting into a more anaerobic exercise. Your customers need to lift more difficult weights to enter the anaerobic zones. Encourage people with many repetitions with light weights to perform fewer repetitions with heavier weights.
It doesn’t need much of your time to be successful. A fantastic anaerobic exercise that targets all important muscle groups for 30 minutes. Making use of heavy weights can help you build endurance with time.
Aerobic vs. anaerobic threshold
The aerobic threshold describes the initial point at which lactate levels rise during exercise. As one’s metabolic rate rises, so do their breathing rate. Since this aerobic system can’t provide enough energy for the activity level, there’s lactate production. It’s not all terrible. Lactate production enables anaerobic power sources to continue generating energy after this.
Triathletes, marathon runners, and cyclists are athletes who exercise for extended periods at lower intensities. They are particularly interested in the aerobic threshold. To prepare for the increased duration of these competitions, athletes may enjoy exercising just below their aerobic threshold. These athletes risk getting fatigued sooner and unable to keep up their pace the entire event if they participate at a speed that is too fast.
Anaerobic metabolic waste products raise blood acidity with increasing exercise intensity. It helps in accelerating the onset of muscle exhaustion. Among other things, hydrogen ion causes fatigue than lactic acid accumulation.
At intensities well over the aerobic threshold we’ve discussed, the body can adapt to rising blood acidity without significantly altering its respiratory rate. However, as you exert yourself, your blood becomes more acidic than the blood buffering mechanisms can handle, and your brain signals this.
Hyperventilation is a form of compensation on the part of the body. The body uses it to aid in the removal of waste. This moment is the anaerobic threshold. It generally corresponds to when blood lactate rises gradually with increased exercise intensity. In other words, at this stage, anaerobic byproducts that lead to muscular tiredness start to build up more quickly than they get eliminated from the bloodstream. Exercise beyond this point is unsustainable and will quickly wear you out.
The two types of metabolism, anaerobic and aerobic, let your body generate usable energy. Nearly all of our energy needs become fulfilled through aerobic metabolism. It is how you generate energy when consuming and utilizing enough oxygen to satisfy your body’s present energy needs. It is the mode you employ, for instance, when resting or going about your regular business.
When your body can’t take in and utilize enough oxygen to fulfill the demands at hand, it employs anaerobic metabolism to produce energy. When you exercise vigorously for brief periods, you expend anaerobic energy.
The anaerobic threshold is the level of exercise your metabolism starts transitioning from aerobic to anaerobic. At this point, breathing becomes noticeably faster. Also, the lactic acid buildup in the muscles becomes noticeable. You start to feel quite worn out. After a while, your muscles will fatigue, and you’ll have to ease up or stop altogether.
