It is widely assumed that exercise is a key part of controlling one’s weight. However, there are many people who find that exercise alone has very little impact on their weight while others seem able to exercise and lose weight easily. What is going on? Well, people all respond slightly differently to exercise due to age, sex and their genetic inheritance. However, despite any difficulty in losing weight that you may have inherited, there are different forms of exercise that will definitely be able to help you lose weight. The different forms of exercise all have different effects on weight loss. Below I look at:
- Easy/medium intensity cardiovascular exercise – aerobic.
- Hard, high intensity cardiovascular exercise – anaerobic.
- Weight training and other resistance exercise.
1 Aerobic exercise
What is aerobic exercise? Aerobic exercise is exercise which most people can sustain for hours if properly conditioned. Heart rates are typically 55-85% of the maximum heart rate. You breathe in oxygen through your lungs at a rate which generally allows you to talk. Your heart then pumps blood containing the oxygen to your muscle fibres. As your muscle fibres contract to produce movement, they use up oxygen. The harder and faster you go, the more oxygen that you need, and as a consequence you breathe faster. As you increase your effort your muscle fibres burn up more sugars and fats to produce the energy required to make them contract. The result? You burn calories faster.
