I’ve been seeing a lot of posts addressing this. My mom and I recently discussed this. I’m studying this in a masters program now so I’m not an expert yet but I’m working on it (all As have to count for something?)
This is something I’ve been confused on as well but now am slightly more educated. It’s changed opinions in the last 5 years because before it was stated that strength training wasn’t so effective in weight loss. Obviously, science goes on and we keep learning. So here are some facts:
- Cardio is good for wait loss. You burn more calories in 30min doing cardio v strength training.
- your BMR (basal metabolic rate) goes up more with strength training than with cardio in a 48hr time frame.
- when you run you aren’t really building much muscle, your loosing fat which is cells which have mitochondria that are responsible for burning fat. All cells have mitochondria but now you are reducing the number you have which drops bmr.
- building muscle increases total cells in the body. The more cardiovascular and muscular(not quite the right word) you are, the more dense the number of intramuscular mitochondria you have.
- the more mitochondria the more ability to do oxidative work. You start running with your new muscular body and those mitochondria are burning cho and fat and your loosing weight.
- a healthy workout routine is 5-6days of cardio and 2-3 of strength/resistance training
- Please do what is best for your body and what you and your pcp/trainer/etc suggest because no 2 bodies are the same
Please see ACSM guidelines for more info
As I said: I’m still learning, if you think I’m mistaken about something please correct me but come at me with research articles in links so I can learn. I hope to always still be learning, research is my passion.
