 Fitness Fact #1:
The only place fat is “burned” in your body is in the mitochondria The mitochondria, which is the “powerhouse” of each cell that helps your body produce energy is the only place where fat is burned in your body (are you getting flashbacks to high school biology?). Assuming you’re following the tips on BuiltLean.com, fatty acids in your body will be transported to your mitochondria to undergo oxidation, which is a process where two-carbon molecules are repeatedly split apart from the fatty acid in a chemical reaction. Fitness Fact #2: Muscles can only “Pull” When I first learned this interesting factoid, I was confused as to how the heck this is possible. I mean, if you do pushups, aren’t your muscles pushing? Well, not really. Even during a pressing motion, your muscles contract, which pulls against a lever that ends up pushing. Muscle can contract and relax. That’s about it. Fitness Fact #3: Exercise can be as effective as medication for relieving short-term anxiety 3 There are many reasons to exercise, but for one benefit in particular – reducing anxiety – exercise is shown by research to be as effective as taking anti-anxiety medications. It is believed exercise helps reduce anxiety for a few reasons (1) it causes your body to release endorphins, which are pain-relieving chemicals that can create feelings of well-being, (2) it takes your mind of stress, and (3) gives you a feeling of accomplishment. Fitness Fact #4 People who are physically inactive can lose as much as 3% to 5% of their muscle mass per decade after age 30 4 Sarcopenia is a term which describes muscle loss in adults as they age. Without regular exercise, muscle loss can lead to deterioration in strength and quality of life. Exercise and proper nutrition can help stave off sarcopenia. So if you are exercising consistently, you don’t have too much to worry about; just make sure you are lifting weights! Fitness Fact #5 Lactic acid does NOT cause the burn in your muscles, but helps the burn decrease 5 That burning sensation you feel in your muscles during intense exercise, referred to as “acidosis” is not caused by lactic acid build up. In fact, recent research has conclusively shown that lactic acid does not exist as an acid in the body, but exists in another form called “lactate”, which decreases the burning sensation, or acidosis in the muscles. Not only does lactate help decrease the burn in your muscles, but it’s an important fuel that can be converted in the liver to glucose, which is then used as an energy source. Lactic Acid. Did you know any of these facts, or find any particularly interesting? Source: https://www.builtlean.com/2010/08/31/5-fitness-facts-you-dont-know/ Comments are closed.
