Different Forms of Exercise is Shown to Affect Hormones Differently
Study finds cardio produces different hormones than strength training specifically FGF21 a metabolic hormone.
I always tell my clients to find a form of exercise or activity that they enjoy, it will help them stay committed to movement if they want to do it. For some that means rock climbing or cross fit, for others it's bike riding or swimming. Whatever you do don't stop moving, that being said when we have certain goals we are trying to achieve some methods are more effective than others. Researchers set out to find out just how the body reacts to the different forms of exercise.
Researchers out of the University of Copenhagen have found that cardio training on an exercise bike produces 3 times as much of the hormone FFG21, as weight lifting. FGF21 is a metabolic hormone that has been shown to aid in weight loss in mice, and is thought to have a similar effect in the human body. The study consisted of 10 young male participants who were asked to perform 60 minutes of vigorous exercise 5 performing a cardio workout and 5 performing a strength training routine. Afterwards they took 8 blood samples over 4 hours to measure different hormones, lactic acid build up, and blood sugar, they not only found the difference in the hormone FGF21 but also FGF19 which has been shown to increase muscle growth. They found that FGF19 hormones actually decreased following a strength training routine. This study is a good start to understanding how our body reacts to exercise but this is only a picture for a small group of male participants for only a short time after an exercise session.
Regardless of what form of exercise done it is done to improve health, little is known about exactly how different forms of exercise training effects health. University of Copenhagen researchers have taken a step to understanding the diverse effects of different forms of training, showing that cardio training on a bike causes 3 times as large an increase in production of FGF21 hormone than strength training with weights does, and FGF21 has many positive effects on metabolism.
