In a recent research that was conducted to analyse the diverse effects of different forms of training on the body, it was proven that cardiovascular exercises and strength training have positive effects on metabolism. Cardio and strength training gives overall fitness and healthy living is a known fact. But they do have different implications.
While some fitness aficionados will happily endure hour-long slogs on the treadmill, others will turn their noses up at anything cardiovascular, choosing instead to spend their workout time lifting heavy weights and ‘getting their pump on’.
However, despite claims that strength training burns more calories than its cardio counterpart, a new study has revealed that cardio training may offer more benefits in terms of metabolism.
It has been conducted at the University of Copenhagen to prove that these different forms of exercises have the ability to affect the hormones that have positive effect on your metabolism.
Boosting one's metabolic rate can be beneficial because the higher your metabolism, the more calories you burn at rest, which can help promote weight loss.
“Of course it is very exciting for us researchers to see how different forms of physical activity actually affect the body differently. We have known about the effects of various forms of training on more well-known hormones like adrenalin and insulin for a long time, but the fact that strength training and cardio exercise affect FGF hormones differently is new to us”, reportedly said Associate Professor from the Novo Nordisk Foundation Center for Basic Metabolic Research Christoffer Clemmensen, who is one of the researchers behind the study.
The researchers, however, pointed out that the results were limited by the fact that the blood samples were not taken more than four hours after the training, and that they could not conclude about the effects of a full training programme on the hormones.
Cardio boosts metabolism more than strength training, Study Claims.
The study from the faculty of health and medical sciences of the University of Copenhagen, showed that cardio training on a bicycle causes three times more increase in the production of the hormone FGF21 than strength training with weights.
Published in the Journal of Clinical Investigation Insight, the study involved 10 healthy young men who were divided into two groups, completing either strength or weight training once a week.
Both training forms lasted for 60 minutes. The cardio exercise consisted of cycling at a level of 70 percent maximum oxygen intake, while the strength training consisted of five exercises repeated 5 x 10 times and involved the important muscle groups of the body like chest, biceps, triceps, quads and the like.
After the period, eight blood samples were taken from the participants over a period of four hours to measure blood sugar, lactic acid, different hormones and bile acid in the body.
The analysis revealed that those who had been cycling experienced a significant increase in the production of the hormone FGF21, which offers numerous positive effects on one’s metabolism, the process by which our body converts food into energy.
