Zone 3 Aerobic Capacity
When you go into Zone 3, youre drawing on the maximum output of the fat/oxidative metabolism.
The benefits of Zone 3 are similar to Zone 2 except that they accrue to a larger pool of muscle fibers due to the increased power output and hence greater muscle-fiber recruitment.
If you are just starting aerobic training, you can do almost all your base training in Zone 3 because your pace at this intensity is going to be slow enough that your muscles will develop without suffering too much. However, if you have a higher aerobic threshold and run at a fast pace in Zone 3, you might risk overtraining from doing too much in this zone while not getting the adaptations from interval training in Zone 4 and 5. This is when you should be looking for recovery in Zones 1 and 2 and then Zones 4 and 5 for intervals of high-intensity work.
Hypothyroidism Symptoms And Signs In An Older Person
Some people over age 60 have few, if any, symptoms of an underactive thyroid gland , while others experience the same symptoms younger people do. Still others have hypothyroidism symptoms that are not typical at all, making the diagnosis even more difficult. Any of the following signs and symptoms can indicate hypothyroidism in an older person.
Unexplained high cholesterol. High cholesterol is sometimes the only evidence of an underactive thyroid in an older person. Because this sign may stand alone, high cholesterol warrants a thyroid evaluation.
Heart failure. Reduced blood volume, weaker contractions of the heart muscle, and a slower heart rateall caused by low thyroid hormone levelscan contribute to heart failure, when your heart can’t pump out blood as effectively as it should The ineffective pumping may cause subtle symptoms such as feeling less energetic or just walking more slowly. In more advanced stages, fluid can back up in the lungs and legs causing shortness of breath and leg swelling.
Bowel movement changes. An older person with hypothyroidism might have constipation because stool moves more slowly through the bowels.
Joint or muscle pain. Vague joint pain is a classic hypothyroidism symptom. It sometimes is the only symptom of hypothyroidism in an older person. Many people experience general muscle aches, particularly in large muscle groups like those in the legs.
Zone 2 Aerobic Development
This is the key zone to work on your aerobic conditioning. Your long sessions in Zone 2 build up your foundation to then push into the high-intensity development sessions. By training in Zone 2, adaptations include an increase in blood volume, mitochondrial mass, and capillary density and aerobic enzymes in the working muscles, all of which lead to an improvement in your aerobic metabolism. Furthermore, long workouts in Zone 2 will also improve your fat metabolism.
When youre just starting a training program, the added benefit of Zone 2 training is that it prepares you for the increased load in training which will follow. This can, in turn, help prevent injuries in the long run.
To get the most out of a Zone 2 session, you should be training for a minimum of 30 minutes at this intensity, but you can go on for several hours . In these sessions, you can work on your technique and economy/efficiency, you can practice your race hydration and nutrition strategies, and test out kit, thus taking advantage of your sessions for more than just aerobic development.

Heart Rate Tips To Keep In Mind
- Start at your beginning. Before getting overly concerned about your heart rate, Martin says, its best to simply get moving. If you havent exercised much before, start where youre comfortable and gradually exert yourself more over time.
- Listen to your body. Your body provides other indicators of how hard its working that you need to consider along with heart rate. Pay attention to how hard youre breathing or sweating, and stop if you feel very uncomfortable, Martin says. Devices recording your heart rate have been known to malfunction, for exampleanother reason listening to your body is important.
- Remember that target heart rate is just a guide. Dont get overly fixated on numbers, Martin says. Ideally, they just push you to work a little harder.

Activity Tracker Or Smartwatch
Activity trackers are easily the most convenient way to measure your heart rate. They’re relatively inexpensive, they don’t take up a lot of space and they have a substantial battery life. Best of all, activity trackers are comfortable enough to wear for long periods of time to get a very accurate measure of your heart rate.
Wearing a Fitbit, Apple Watch, Garmin or other tracker allows you to measure your heart rate at all times of day: when you’re sleeping, during typical daily activities and during exercise. They then present this data to you in an easy-to-digest way. Activity trackers and smartwatches use optical technology to read the pulse in your wrist. With optical technology, your tracker sends light into your skin and reads the light that bounces back.
The Apple Watch Series 5 can even generate a PDF of your heart rhythm that you can share with your doctor.

How To Find Your Real Maximum Heart Rate
by: Shin Ohtake, Fitness & Fat-Loss ExpertAuthor of MAX Workouts, The Ultimate Lean Body Fitness Program
Exercising within your target heart rate zone has long been accepted as a standard training protocol, but what if I told you that the formula for calculating your max heart rate is inaccurate? And that even the doctor that created the formula admits to being completely surprised at how the medical and fitness communities have made it the standard formula, without anyone actually doing any extended research.
Heres the real story on how the formula for calculating your max heart rate came about :
Can you imagine if your MHR was 160, but according to the formula your MHR was supposed to be 185? You could push your self until you passed out and still not reach your calculated MHR. Or, on the other hand, what if your MHR was actually 200, but the formula calculated it to be 180? You would always be training at sub-par intensities, wondering why the people around you were sweatin up a storm when you barely broke a sweat.
The truth is that the popularity of the formula was more about timing than about exact science. It was available at just the right time, when people wanted an easy way to objectively figure out an intensity that would satisfy filling the criteria for both the medical field as well as the fitness field.
So what is the best way to find out how hard you need to train, without going into the danger zone? Well, you have a couple of options.

Calculate Your Target Heart Rate Range
- Using the Heart Rate Reserve Method:
THR = [MHR RHR ) x % intensity + RHR
The intensity levels are:
- Moderate intensity 40-49% HRR
- Vigorous intensity 50-59% HRR
-
For example, for a vigorous-intensity workout, start with the lowest HRR percentage to calculate the lower limit of that intensity range:
THR = + 60 = + 60 = 138 bpm
- Next calculate the upper limit of that intensity range using the same formula, except use the higher percentage this time .
- The lower and upper limits form your THR Range.
- So using the example of a 25-year-old with a resting heart rate of 60 bpm who wants to do a vigorous workout, he or she should aim to achieve a heart rate range of 138176 bpm.

How Do I Track Heart Rate With My Fitbit Device
Learn how Fitbit tracks your heart rate day and night, and see tips to get a more accurate reading.
When your heart beats, your capillaries expand and contract based on blood volume changes. To determine your heart rate, the optical heart-rate sensor in your Fitbit device flashes its green LEDs many times per second and uses light-sensitive photodiodes to detect these volume changes in the capillaries above your wrist. Then your device calculates how many times your heart beats per minute . The optical heart-rate sensor detects a range of 30-220 bpm.*
We use green LEDS because they maximize the signal detected from the capillaries near the surface of the skin. The optical heart-rate sensor also uses infrared light to determine when the device is on your wrist to improve the accuracy of your heart-rate data.
*This range applies during sleep while youre awake, the range is 40-220 bpm. On Fitbit Versa 2, the range is 30-250 bpm.
Swipe up on your clock face to see your current heart rate and either your heart-rate zone or resting heart rate . To see heart rate details, tap or swipe .
If your device has an Exercise app, you can check your real-time heart rate and heart-rate zone during a workout. Note that your device doesn’t track your heart rate during swims.
What Happens When I Receive A Heart
When your Fitbit device detects your heart rate goes above or below your personal heart rate threshold while youre inactive, you receive a notification on your Fitbit device. Tap Open, and then tap the notification in the Fitbit app to learn more about your data and complete a survey where you log any potential factors, medications, and symptoms. You can use the info you log in the survey to track your heart health trends and share it with your healthcare provider.

Resting Heart Rate And Health
A relatively low resting heart rate is considered healthy, while a high resting heart rate may increase the risk of various conditions.
A lower heart rate allows the heart to maintain a healthful rhythm and respond to routine stressors efficiently. These may include exercise, illness, and day-to-day activities.
Having a relatively low heart rate is a significant contribution to overall health. An abnormally high heart rate can lead to a variety of health risks and conditions.
Complications associated with a high heart rate include:
- low energy levels
Stress may cause a high heart rate.
Each heartbeat arises from specialized muscle cells called myocytes.
When these cells need more oxygen, as during exercise, the brain sends messages to the heart, causing myocytes to make stronger, more frequent pulses.
Everyone experiences sudden, temporary changes in their heart rate. They may be caused by:
Having a chronically high or abnormal heart rate is often a sign of an unhealthy lifestyle or an underlying medical condition.
Common long-term causes of a high heart rate include:
- lack of exercise

A normal heart rate is believed to be between 60 and 100 beats per minute. But some experts tend to think that the ideal resting heart rate is 5070 beats. The causes that can provoke tachycardia can be dangerous or they just represent our reaction to the conditions we live in . If you notice that your heart works faster, the first thing you should do is to consult a doctor.

What Affects Heart Rate
Many biological factors can affect your heart rate including your age, body size and current body position. If you have a fever or slept poorly, you might notice a higher heart rate.
Your fitness level is another factor to consider. People who are more active may have lower resting heart rates. An athletes resting heart rate might even go below 50 BPM.
Psychological factors, such as your emotional state, can also influence your BPM. If youre feeling stressed out, youll notice your heart rate increase.
Smoking will also increase your heart rate. And thats just one of many ways smoking can have a negative effect on your overall health.
Some medications can influence how fast your heart beats. Substances with caffeine, including coffee and tea, can elevate your heart rate as well.

Is Resting Heart Rate Different By Age
For most of us , between 60 and 100 beats per minute is normal.1 The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now thats chill!
When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesnt have to work as hard to maintain a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness and higher blood pressure and body weight.2
