Physical Activity

Defined as any bodily movement produced by skeletal muscles that results in energy expenditure, physical activity makes important contributions to a person’s health, sense of well being and the maintenance of a healthy weight.

Maintaining regular physical activity increases one’s ability of physical fitness, helping you to meet the demands of everyday tasks and work. People with higher levels of physical fitness also have a lower risk of developing chronic disease.
Leading a sedentary lifestyle increases the risk of developing issues with excess weight including obesity, and many chronic diseases such as coronary heart disease, high blood pressure, high cholesterol, type 2 diabetes, osteoporosis and certain types of cancer.

Mortality rates from all causes of death are lower in people who are physical active than those who live a sedentary life.

The following are recommendations to promote health and well being and a healthy weight.

· If you are new to exercise, engage in at least 30 minutes of moderate physical activity on most days of the week. · As you become fitter increase the intensity of your activity or the duration of your workout. Greater benefits can be obtained when exercising at a more vigorous intensity. · Monitor calorific intake each day. · Aim to build up to 60 minutes of physical activity on most days of the week to help sustain or maintain a healthy weight in adulthood.

Physical activity should include cardiovascular training, stretching exercises to improve flexibility and resistance exercises for developing strength and endurance.
In addition to physical activity helping in weight management and lowering the risk of chronic diseases, it has been proven to reduce the feelings of anxiety and depression.

It is also important to remember to reduce the amount of sedentary behaviours each day and week. Limit the time spent watching television and playing video games and replace with activities that require movement.

Prevention of weight gain is critical; as the more you weigh the more challenging it will become to change lifestyle habits. Since people gain weight slowly, small decreases in calories consumed can make a big difference, especially when combined with increases in physical activity.

Remember this number, 3,500 calories per pound of fat. If you reduce you calorie intake by 250 calories per day and increase your physical activity by 250 calories per day, then you will have a calorie deficit of 500 calories per day. Over 7 days that equally 3,500 calories and 1 pound of fat lost. Not bad for just making some small but smart changes each day.

Simple steps that can be implemented straight away are reducing the amount of sugar, fat and alcohol consumed each day. These foods provide calories but very few or no essential nutrients. Also portion control is another key in keeping calories down. Cutting back on the amount served per meal and understanding serving sizes can help reduce calories.
