Muscle-building ‘Exercise pill’ found to improve the markers of heart health without weight loss, reveals study.
Myostatin or muscle cell protein could be suppressed to enhance the muscle mass and improve markers of heart and kidney health, finds a recent study conducted in mice. The research work will be presented at the American Physiological Society’s annual meeting during the Experimental Biology 2017 meeting.
‘Suppressing a particular muscle protein through an ‘exercise pill’ could enhance muscle mass and reduce the risks associated with obese people.’
The researchers zeroed in on myostatin because it is known as a powerful inhibitor of skeletal muscle growth, meaning that people with more myostatin have less muscle mass and people with less myostatin have more muscle mass.Studies suggest obese people produce more myostatin, which makes it harder to exercise and harder to build muscle mass.
"Given that exercise is one of the most effective interventions for obesity, this creates a cycle by which a person becomes trapped in obesity," Butcher said.
Obesity is linked with a range of factors that increase the risk of heart disease and diabetes, including high blood pressure, high cholesterol, insulin resistance and kidney damage.
The researchers bred four groups of mice: lean and obese mice with uninhibited myostatin production and lean and obese mice that were unable to produce myostatin. As expected, mice that were unable to produce myostatin developed markedly higher muscle mass, though the obese mice remained obese even with more muscle.

"In our muscular obese mouse, despite full presentation of obesity, it appears that several of these key pathologies are prevented," Butcher said. "While much more research is needed, at this point myostatin appears to be a very promising pathway for protection against obesity-derived cardiometabolic dysfunction.
