How Does Age Affect Physical Activity: An Overview

How Does Age Affect Physical Activity

Let’s admit it; we are all moving slowly in the direction of death from the minute we are born. Until a particular point in that timeline, when our fitness levels start to fall, we develop stronger and fitter. There is nothing we can do to change the fact that it exists. 

It’s true that as you age, there’s a lot of problems an older adult will be facing, fears, pains and your ability to exert yourself to the fullest extent will reduce. You will also lose your ability to recover rapidly from extended or strenuous physical activity, but you can still take action.

This article will explain how aging affects our level of physical exercise as part of old age problems, so read on!

How does your fitness change as you age?

Numerous research conducted over the years have revealed the following:

Between the ages of 20 and 35, you achieve your physical zenith. Early middle age is characterized by a drop in physical activity and increased body fat from 5 to 10 kg. As people age, their level of physical activity continues to diminish.

Your maximum heart rate decreases with a 1% annual decrease in your maximal oxygen intake. Oxygen uptake is crucial as most of your muscle energy is made by combining oxygen with the fuel in your body (carbs and fat). The faster you transport and use oxygen, the faster you can go and the longer you can keep going.

Fast-twitch muscle mass, essential for producing the force required for high-intensity exercise, decreases significantly between the ages of 31 and 40 (about 3% per year) and subsequently falls at a rate of roughly 1% per year beyond that.

Nevertheless, there’s no need to give up just yet. Since the majority of the studies that came to the conclusions mentioned above were based on declines in physical ability relative to an individual’s maximum exercise capacity, you have a pretty good chance of maintaining your mobility as you age or even outperforming previous results if you haven’t been exercising to your maximum capacity, which is true for the majority of people besides elite athletes.

Another way to look at it is that while there is no doubt that your maximum capacity will decline with age, you may maintain or even increase your current fitness level by working toward your maximum ability more and more each year. 

Must Read: Why Do Older Adults Lose Weight?

How much exercise do older people need?

Regular physical exercise is one of the most crucial things you can do for your health as an older adult. Several age-related health issues can be avoided or delayed by using it. Also, it supports muscular growth so that you may continue carrying out daily tasks independently.

Remember that even a little exercise is better than none at all. The more physical exercise you engage in, the more benefits there will be for your health.

Older adults whose age is 60 and above must have the following:

  • A minimum of 150 minutes per week—30 minutes per day, five days per week—of moderate-intensity exercise like brisk walking. 
  • At least two days each week should be dedicated to muscle-building exercises.
  • Around three days each week, engage in balance-enhancing exercises like standing on one foot.
  • Be as physically active as your skills and conditions permit if chronic problems prevent you from following these instructions.

What are the physical needs of adults?

Being able to support oneself and take care of one’s requirements, especially basic physical demands, is a necessary part of maturing into a young adult. Here’s a physical need that seniors must have.

  • Air Purity
  • Food
  • Water
  • Shelter
  • Physical exercise

What can you do to help enhance your physical well-being as you age?

Even though most research focuses on how exercise affects weight and BMI, studies have shown that exercise can improve your quality of life even if you are not losing weight. There are numerous ways to start. 

Try engaging in brief physical activity throughout the day or designating specified hours each week to work out. 

As you become more active, you will stop feeling weary after working out and feel rejuvenated and refreshed. The idea is to discover strategies for being motivated and acting. 

Taking good care of your body

While scientists are still actively investigating ways to decrease or stop the physical health impairments that come with aging, they have already found numerous techniques to increase the likelihood that one will live a long and healthy life.    

Maintaining and managing mobility, physical fitness is being physically active, eating well, getting enough sleep, avoiding alcohol, and taking charge of your health care. To encourage healthy aging, little adjustments in any of these areas can make a big difference.

Healthy Eating: Select nutritious foods

Making wise eating choices can help you avoid some health issues as you get older and may even aid with improving brain function. Eating healthy is not simply about your weight, like exercising is not. Choosing what to eat might be difficult because so many different diets are available.

Advantages of Exercise for Older Bodies

Regular exercise has a variety of advantages for seniors, including the following:

  • Age causes a reduction in muscle fiber quantity and size. The “quick twitch” (phasic) muscle fibers, which control the strength and rapid contraction, appear to be most affected. Evidence points away from age and toward a sedentary lifestyle as the cause of these alterations.
  • After 40, bone density starts to deteriorate; however, this loss quickens around 50. Older persons are more vulnerable to bone fractures due to this bone loss.
  • The best exercise for the heart and lungs is moderate intensity; for instance, exercising at roughly 70% of the person’s maximal heart rate (220 beats per minute minus your age).
  • Body joints must be regularly moved to stay flexible and healthy. Exercise regimens that combine aerobic activity with strength training benefit people with arthritis.
  • Body fat percentages—excessive body fat has been linked to diabetes and cardiovascular disease, among other disorders. Regular exercise builds muscle mass, burns calories, and quickens metabolism.

Aging’s Physical Decline

A lack of physical activity may account for around half of the physical decline of aging. People over 50 who don’t exercise regularly risk developing many health issues, such as:

  • diminished strength, physical stamina, and muscle mass
  • impaired balance and coordination
  • decreased joint mobility and flexibility
  • lowered heart and lungs and other systems’ performance
  • decreased bone density
  • increasing levels of body fat
  • higher blood pressure level
  • greater propensity for mental health issues like anxiety and despair
  • heightened potential for many illnesses

Misconceptions regarding older people and exercise

Numerous senior citizens think exercise is no longer appropriate. Common myths that lead elderly individuals to stop exercising include the following:

  • Physically feeble and frail
  • As we age, our bodies don’t require as much physical exertion.
  • Older folks should avoid exercising since they run the risk of getting hurt.
  • Only continuous, intense exercise has any benefit.

Getting active advice for seniors

Some suggestions are:

  • See your doctor before beginning a new fitness regimen if you are over 40, obese, have a chronic condition, or have been sedentary for a while.
  • Pick interests-based activities. If exercising is enjoyable rather than a chore, you are more likely to stick with it.
  • Exercise with pals. Make exercising pleasurable and a social event.
  • Walking, swimming, and cycling are secure, simple, and comfortable exercises.
  • Your muscle mass can improve with weight training; successful regimens can last as little as 6 to 8 weeks.
  • Aim for modest advancements as you begin.


Age-related declines in exercise capacity are correlated with an increase in the oxygen cost of exercise and a decline in exercise efficiency. Exercise training can revert these age-related changes, and it does so more effectively in older people than in younger people. 

Although older adults are more likely to increase their power and muscle mass through exercise, acquiring muscle as they age is difficult.
