Recent research shows that exercise is effective in lowering blood pressure. All types of exercise including both cardiovascular and resistance training were beneficial. Blood pressure medication is more effective than exercise in creating a difference but this research is still very encouraging for people to keep up their exercise. Please make sure you check with your doctor before starting a new exercise program. See our Facebook post for further information.
You have probably heard that it isn't just exercising alone that helps you to lose weight, it is mainly what you eat. Research discussed in the New Scientist, January 19, 2019, shows that our bodies have a set amount of calories that it uses per day so extra exercise doesn't allow you to eat too much more food. There are several reasons for this:
1) if someone does a heavy work out, they often compensate for this by being less active or fidgety throughout the rest of the day because their body is recovering. This was shown in mice who were given running wheels and prompted to exercise, they were less active for the rest of the day.
2) People who are used to exercising become more efficient at using calories, therefore, they don't need as many calories for their daily life and exercise.
3) Our bodies have possibly evolved to use a certain amount of calories regardless of the activity we are doing. The Hadza people in Tanzania, are very active. The men walk at least 10km/day hunting for game and the woman gather food by digging for wild tubers and picking berries yet still only burn around 2000-2600 calories/day. This is only slightly more than people who drive to work and sit all day. It takes more energy and effort for a larger person to go about their daily life than an individual in a healthy weight range. When people start to lose weight, their metabolism slows down. If they start to put it back on, their metabolism stays at the slower rate as if their mass was smaller compared to their pre-weight loss state. This makes it easier to put weight back on, because our bodies have evolved to make sure we survive - smart, but kind of unfair given the abundance of food in this day and age!
If a person exercises like crazy, their metabolism also slows down because their body isn't spending enough time repairing their internal systems and can find themselves with injuries that don't heal, not being able to shake a cold or having disrupted menstrual cycles. However, there are good reasons to do moderate amounts of exercise as there are a myriad of other health benefits: improved cardiovascular health, better brain function and reduced risk of chronic conditions such as Alzheimer's.
