The Benifits of Movement and Exercise and what happens if we dont ?- By Melanie Gabbi

with No Comments

The exercise industry has been around since the 70’s. Since we saw the film Flash Dance, a whole range of fitness classes have been introduced. But here’s a clip of Flashdance. A film that encapsulated the trend at the time, and skyrocketed sales in the fitness industry.

(see dance for a full review. This film inspired a whole generation to get some leg warmers and try a step class.
Since then we’ve been sold the idea that step classes, gym membership, swim passes and lately boot camps, are the way to get fit. but what is the attraction? what is it we are trying to do?
I mean why do we exercise,or even move? and what are the consequences if we don’t ? lack of mobility, movement or exercise can have some serious consequences .
A lot of people assume that we only exercise to help us lose weight. For others, it’s a fun activity that will also give them a range of results. For those who do regular activities, it can mean they get to feel the thrill, of getting their pulse racing. There is something about beating the previous score. You can leave the gym or studio feeling the buzz in your body for hours afterwards. Some exercise early in the morning as it can set them up for the day. Doing so can help them feel alert and get their mind and body working.
We get bombarded by a range of different ideas about how to get fit, healthy and what we should be doing. So it can feel all to much of a mine field.
Movement can mean simply doing some additional activities during each day . Sometimes, even just five or ten minutes of movement, can make a difference within a few days . Longer term these extra daily activities can add up. Movement needs to become a part of developing and maintaining a healthy lifestyle. One that is free of aches, pains or even disease.
Movement just means not staying static. It can mean doing housework, gardening or taking the dog for a walk. It means doing something every few hours to get the body moving. It doesn’t matter what you do to move-you just need to do it. Enjoying your activitys means its much easier to stick to something you enjoy.
Start today, do something more than you usually do, even if its ten minutes.
Below is a research article I’ve included and an extract of some work done on the impact of too much sitting.
Research on sitting and the impact of movement 
Jaclyn Chow a Senior Physiotherapist with Tan Tock Seng Hospital- writes about “To Much Sitting, and the impact of too Little Exercise.
The importance of physical activity
Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy. According to the World Health Organisation, physical inactivity has been identified as the fourth leading risk factor for global mortality, causing an estimated 3.2 million deaths worldwide. Physical activity is a modifiable risk factor for cardiovascular disease. There is strong evidence to show that moderate to vigorously intense physical activities plays a key role in preventing cardiovascular disease by targeting risk factors such as type 2 diabetes, hypertension and obesity.
The benefits of physical activity also extend to patients with existing cardiovascular disease. In the past, rest and reduced activity have been recommended for patients with heart disease. However, this is no longer advocated.
How sitting is bad
• People with sitting jobs have twice the risk of cardiovascular disease compared to those with standing jobs
• Fat burning drops drastically to 1 calorie per min the moment we sit
• Every 2 hours spent just sitting reduces blood flow, raises blood glucose and drops good cholesterol by 20%
• Watching television for 6 hours a day takes away 5 years off your life
• Walking burns 3-5 times more calories that sitting does. Take every opportunity to walk around the office
• Interrupt sitting whenever you can
In recent studies, strong evidence has shown the importance of engaging in regular exercise to slow down or reverse the disease process. Slowing down the progression of coronary artery disease.
The recent health recommendations from the American College of Sports Medicine and the American Heart Association continue to stress the importance of participating in at least 30 minutes of moderate intensity physical activity or 20 minutes of vigorous-intensity physical activity for at least 5 days a week,. Accumulating a minimum of 150 minutes a week. In addition to the activities of daily living- such as standing, walking slowly and lifting objects.
With advances made in the modern world, the need to be active is significantly reduced. People can now spend the majority of their waking day in a chair watching television, working at a desk, ordering and receiving items in the comfort of their homes such as take-out and online shopping etc.
A study by the Singapore Heart Foundation in 2010 revealed that only 19% of adults aged 18 to 69 years exercise regularly and more than half of Singapore residents do not exercise during their leisure time. Although the human body is made to be in frequent motion, people can sit for many hours at a time, day after day.
Sedentary behaviour has been the new focus for research in physical activity and health. This phrase ‘sedentary behaviour’, originates with the Latin word “sedere” which means “to sit”. Sedentary behaviour is defined by their posture (sitting or reclining) and their low energy expenditure .
Recent studies have shown that time spent in sitting have an independent impact on increasing cardiovascular risk factors . This highlights that physical activity does not cancel out the ill effects of too much sitting during the day. These effects are further magnified in people who do not exercise and remain sedentary for most of their day. The highest mortality risk is seen with people who are obese.
So how much sitting, is ‘too much’?
According to a US survey, at least half, and up to two thirds of an adult’s waking hours are spent sedentary which range from 6-10 hours a day. Prolonged sitting has an impact on mortality and life expectancy. Too much sitting impairs the body’s ability to deposit fat from the blood stream into the body. In addition, too much sitting during the day impairs the functioning of the body’s good cholesterol. In a nutshell, the more you sit, the higher the risk of increasing your systolic blood pressure, waist circumference, blood glucose.
All studies are indicating that moving more during the day, in addition to getting the daily 30 minutes of moderate activity on a daily basis, is necessary to lower one’s risk of cardiovascular disease and other causes of mortality.
The Remedy: Stand up, sit less, move more, more often
Now that we know that sitting increases cardiovascular disease risk, how can we turn things around?
This is especially important for people who are in occupations which involve prolonged sitting. For example: office workers, transport drivers and those who have to sit due to musculoskeletal disorders like osteoarthritis. The key here is breaking up sedentary time with light activities such as standing and normal paced walking.
Studies have shown that insulin action improves with more standing time and stepping time. The effects of light activity compared to moderate activity is shown in another study. Sitting, interrupted by a short 2-minute bout of walking showed similar, significant reductions in post-meal glucose and insulin. Light activity plays a beneficial role in reducing the adverse effects of prolonged sitting.
The importance of regular exercise should continue to be emphasised. Everyone is encouraged to create opportunities to limit your sitting time at home, at work. Break-up long periods of sitting through frequent walks as much as possible throughout the day. The key to minimising cardiovascular disease is: ‘stand up, sit less, move more, more often’.
The following information may be useful in offering you practical suggestions in reducing sitting time throughout the day, as well as through a 5-minute desk workout.
If you are above the age of 40, or have any existing medical conditions, or recently been inactive or concerned about your health, it is advisable for you to consult a doctor before starting on any moderate-vigorous intensity physical activity.
Not all exercise programmes are suitable for everyone, and some programmes may result in injury. Activities should be carried out at a pace that is comfortable for the user. Discontinue participation in any exercise activity that causes pain or discomfort. In such event, please seek medical consultation immediately.
