Let’s say you are in a gym. Now you are deadlifting and doing bench press all you can to bulk up your muscles so you get stronger afterward. But, does muscle hypertrophy really increase your strength? Not necessarily.
According to study at the University of Mississippi, an increase in muscle size with hypertrophic exercises may not be directly related to an increase in muscle strength. The study is based on existing evidence and researchers have concluded that size and muscle strength may actually be separate phenomena. The findings, however, challenges many assumptions upon which exercise programs have been based.
The researchers come to this conclusion after they see people who abandon the gym can still maintain their strength they have built up for months even if there is a loss of muscle mass. Similar muscle growth can occur with low load or high load resistance training, yet there are divergent results in strength, the team noted.
“As the story goes with exercise-induced changes in strength, neural adaptations are contributing first with muscle growth playing a more prominent role in the latter portion of a training program: however, there is little direct evidence that this is actually true in an adult partaking in a resistance training program,” explains Dr. Jeremy Loenneke, senior author of the Muscle & Nerve article, in a news release. “Our paper highlights many potential issues with how we think about changes in strength following exercise.”
