Could obesity actually be a problem at the cellular level? Inside cells are tiny organelles called mitochondria that produce energy. Some research shows obese people have mitochondria that function differently. Does obesity begin at the level of the mitochondria?
Carbohydrates and fats are the macronutrients your body prefers to use as a fuel source for exercise. How does it “choose” which one to use during a workout? Here are five factors that impact fuel use and selection during a workout.
Are you too focused on how many calories you’re burning during a workout? Don’t be. This article discusses what determines how many calories you burn when you work out and why it shouldn’t be the focus of your workouts.
Mitochondria play are powerful energy producers inside cells. These tiny organelles are easily damaged by exposure to free radicals. This damage may play a role in aging. Until more is known, the best way to keep your mitochondria healthy is to do regular physical exercise, aerobic and a combination of aerobic and resistance training. Top it off with a healthy, antioxidant-rich diet that’s free of processed foods. Can’t go wrong with that!
How long should you rest between sets to maximize your results when resistance training? It all depends on what you’re trying to achieve. Find out how rest periods impact the results you get when you train and how to decide how long to rest between sets.
Your body responds to endurance training in a number of ways. It makes adaptations that give you greater exercise endurance and a more efficient cardiovascular system. Find out more about adaptations to endurance exercise and discover six things that exercise increases.
Fats, carbohydrates and proteins – your body can use them all to produce energy to fuel muscle contraction. How does it know which one to choose? Find out more about fuel usage during exercise – when your body uses carbs and when it turns more to fats – and what factors influence it.
How is your mitochondria health? There’s growing evidence that “dysfunctional mitochondria” inside cells plays a role in chronic diseases of aging and the aging process itself. Find out why and how exercise helps to keep mitochondria healthy.
The ATP molecule is the molecule that muscle cells use for energy transport and is made in two significant ways, aerobically and anaerobically. Understanding both of these methods will help you to target your workouts to match your fitness goals.
Do you know how your body generates energy to fuel exercise? Find out more about the ATP three-part energy system the body has for fueling your workout.
