EXERCISE
One of the biggest problems in Australia today is lack of activity. We know it's good for us but avoid it like the plague either because we're used to being sedentary or afraid that exercise has to be vigorous to be worth our time. The truth is, movement is movement and the more you do, the healthier you'll be. Even moderate activities like chores, gardening and walking can make a difference.
This can be especially true for people living with Lung Disease. The amount of air you need to breathe in depends on how active you are. When you are sitting down you only take in about 15 breaths a minute, giving you around 12 litres of air. From this your lungs will extract just one fifth of a litre of oxygen.
Through exercise – even moderate - you can train your body so that more oxygen is delivered to your muscles.
Unfortunately, many people with long-term lung problems are afraid to exercise. This is partly because they are worried that being breathless may be harming them. This isn't true. By gradually building up the exercise you take, you can help to improve your breathing and feel better.
People with severe lung problems benefit a lot from even small amounts of exercise, so it really is worth keeping as active as possible.
What happens when you exercise?
As you start to move about, the muscles in your body send messages to your brain that they need more oxygen. Your brain then sends signals to the muscles that control breathing - your diaphragm and the muscles between your ribs - so that they shorten and relax more often. This causes you to take more breaths.
More oxygen will be absorbed from your lungs and carried to the muscles you are using to exercise - mainly your arms and legs.
Why do muscles need more oxygen?
For you to become more active your muscles will need to produce more energy. They do this by breaking down glucose from your food, but to do this they need oxygen. If there is too little oxygen they will try to produce energy in a different way. But this can lead to a build-up of a chemical called lactic acid, which causes cramp - something that many athletes are all too familiar with.
Athletes train so that their lungs and muscles become more efficient and it takes longer for lactic acid to build up. This means that their muscles can work harder. In fact, everyone can benefit from exercise to strengthen their lungs and muscles.
What happens when your lungs don't work properly
People with long-term lung problems such as COPD may find their lungs unable to provide enough oxygen for their muscles to perform even simple activities. When walking short distances their lungs may struggle to keep up, causing breathlessness.
Physical training

Begin slowly by doing arm and leg movements while you are sitting down. Then set yourself targets for walking about: from room to room, going to the front door, the bottom of the garden, down the road and so on. It's surprising how quickly you'll be able to do more.
Some easy exercise tips
Turn off the TV. Once a week, turn off the TV and do something a little more physical with your family. Play games, take a walk...almost anything will be more active than sitting on the couch.
Walk more. Look for small ways to walk more. When you get the mail, take a walk around the street, take the dog for an extra outing each day or try walking around your home for 5 minutes at a time.
Do some chores. Working in the garden, raking leaves, sweeping the floor...these kinds of activities may not be 'vigorous' exercise, but they can keep you moving while getting your house in order.
Pace while you talk. When you're on the phone, pace around or even do some cleaning while gabbing. This is a great way to stay moving while doing something you enjoy.
Be aware. Make a list of all the physical activities you do on a typical day. If you find that the bulk of your time is spent sitting, make another list of all the ways you could move more - getting up each hour to stretch or walk a short distance, etc.
