Why Do You Get Tired So Quickly? How to Improve Stamina in Adults

Do you feel like your stamina is lacking? Do you find yourself getting tired quickly during the day or after exercising for only 15 minutes? If so, your body likely needs more oxygen. According to a study by Stanford University researchers published in the Journal of Applied Physiology, low oxygen levels could be the cause of fatigue and decreased performance. However, there are easy ways to increase oxygen levels in your body! Read on for several tips about how to improve stamina in adults.

What is Stamina and How to Evaluate It?

Stamina is defined as the ability to sustain an effort, activity, or process. According to Mayo Clinic, stamina in adults can be assessed by measuring your heart rate during physical exertion and how long you can keep it elevated. For example, if you were working out on a treadmill at 60% of your maximum heart rate for 15 minutes before feeling exhausted – your stamina would be considered low.

Factors That Affect Stamina Level in Adults

While you cannot control some factors that affect your stamina, such as genetics and age, there are many things you can do to improve it.

Medical Conditions

Several medical conditions may inhibit the ability of an adult’s body to process oxygen. These include asthma or emphysema (chronic obstructive pulmonary disease). Even if you don’t have any medical conditions, your doctor has told you that your heart is weak or decreased circulation could be to blame.


As you age, it’s natural for the body and its cells to function less efficiently than when we were younger – including our muscles. This means they need more oxygen to work correctly.

Aerobic Capacity

If you are not physically active, your aerobic capacity will be lower. Aerobic capacity is the maximum amount of oxygen circulating in a person’s body when doing physical exertion for long periods. To improve this, start by exercising three times per week and slowly working up from there.

Endurance vs. Stamina: is There any Difference?

What is Endurance?

When someone talks about their ability to “endure” something or how long they can endure, they usually talk about their endurance level. Endurance is the length of time an individual can strenuously perform a task without stopping or rest. While many tasks could be performed, endurance is usually associated with physical activities such as running, swimming, biking, and anything else where you’re using your muscles for an extended period. So, think about how long you’ll be able to run before it becomes too much.

What is stamina?

Stamina, on the other hand, is a term that describes your physical endurance in general. It might be used to describe your ability to perform physical activities or how well you’re able to handle a strenuous environment, such as a hot and humid climate. Being fatigued also leads to an individual having less stamina. So if you’re able to run for a long time, you have high stamina levels.

Ways to Improve Stamina in Adults and Seniors

Stress Management

Stress control is significant because stress can lead to many different heart diseases. Since the heart is a muscle, any stress means you’re working it harder. Also, chronic stress leads to adrenal gland fatigue, which will cause you not to be able to handle physical activity. You might find yourself out of breath or fatigued more easily.

Hormone Therapy

Growth hormone and HGH are essential for men and women as it helps increase muscle mass and strength. Also, cortisol levels need to be checked because these are the stress hormones that signal your body to release sugar and fat into your bloodstream so you can use them for energy. High cortisol levels will lead to adrenal fatigue and thus reduced stamina.

Benefits of HGH Hormone Injections for Patients with Chronic Fatigue Syndrome

Hormone replacement therapy with testosterone and estrogen is essential for seniors who have HGH deficiencies helps them remain active, healthy, and independent. The low levels of these hormones lead to decreased energy, increased fatigue, and inability to recover from physical activity or illness. Those who consider the possibility of undergoing the treatment and want to buy HGH in US, should know that official prescription and proved low Growth Hormone levels  are required.

Yoga and Meditation

Yoga has many positive effects on your body. It increases flexibility, which allows you to move more freely and reduces the risk of injuries. Yoga is also often characterized by controlled breathing, so it helps keep your respiratory system healthier as well. Meditation calms the mind and relieves stress, which leads to reduced cortisol levels. These are all good things if you need to improve your stamina levels.

How to Improve Stamina in Adults?

Below are several tips on how to improve stamina in adults and seniors:

  • Consume caffeine, such as coffee, before your workout. Caffeine is a natural stimulant and will help you perform better during physical activity by increasing endurance and decreasing fatigue. Consuming caffeine may also reduce your perception of pain.
  • Perform aerobic and anaerobic exercises that get you breathing heavily, such as running or cycling. These types of activities will help increase the amount of oxygen in your blood and improve stamina.
  • Eat foods with a high concentration of carbohydrates before exercise. Carbohydrates provide energy for physical activity by releasing glucose into your bloodstream while oxygen is breaking it down.
  • Choose exercises for seniors that require shorter periods of activity but are done at a more intense pace. For example, try interval training instead of spending hours on the treadmill to improve stamina while getting a great workout.


So, if your goal is simply to run for more extended periods before getting tired, start increasing the length of the activity gradually. If your goal is more general lifestyle improvement through improved health and fitness levels, consider the other suggestions you learned about.

Now that you have some ideas on improving stamina in adults and seniors, which excuse do you have not to get started?
