Study Shows Building Lower Body Muscle Is Harder Than Building Upper Body Muscle

Researchers showed via MRI that building lower body muscles is harder than building upper body muscles.


A lot of guys who have actually been exercising with weight for a long time currently understand exactly what Japanese sports researcher found 15 years ago utilizing MRI scans: the muscles in the upper body grow faster than those in the lower body.

Research study
The scientists, who were connected with the Tokyo Metropolitan University, had 3 men exercise with weights for 16 weeks. The men trained 3 times a week, then did work with 5 basal workouts – the squat, leg-extension, leg-curl, bench press and lat-pulldown – the most essential muscle groups of the body. The men did 3 sets of each workout, and trained with a load with which 8-12 reps were possible.

Prior to and after the 16 weeks training duration, the scientists identified the body composition of the men utilizing MRI.

After the training duration the males were 2.3 kilos much heavier, however in accordance with the MRI scans the males added no less than 4.2 kilos of muscle mass.

If strength training newbies wish to know the number of muscle gains they have actually gotten just recently, they clearly can not count on a regular scale. It undervalues the variety of kilos of newly gotten muscle mass.

The MRI likewise showed which muscles had actually grown significantly, and which less. The best development had actually taken place in the muscles of the upper body. The big muscles in the lower body – the glutes and the quads – grew slower. That is exceptional, since 3 of the 5 workouts that the guys had actually done, promoted the muscles of the lower body.

Researchers Conclusion
"If changes in muscle hypertrophy were constant across every muscle, then a single anatomical cross sectional area would reflect changes in skeletal muscle mass", the researchers wrote. "However, our data show that muscle hypertrophy did not occur uniformly throughout each individual muscle or region – for example, trunk, arm, and leg – of the body."
