How a dollar-and-a-half injection can help your body pump out the hormones it needs to rebuild after a hard workout, while a $100,000 drug injection can give you more energy and make you feel more rested and ready for a tough workout.
The new research published in the journal Nature suggests that the body can use a little extra energy to restore energy levels, as well as keep your muscles and muscles tendons and ligaments from falling apart.
And while the study doesn’t provide any evidence to suggest that the injections are effective for boosting strength, it does suggest that they can help people build muscle and endurance and even improve recovery time after injury.
“We found that these injections did work,” said lead researcher Dr. David S. Hwang, a professor of internal medicine at the University of Illinois at Chicago.
“But they did not increase muscle mass or strength.”
The study included 40 people who participated in the National Strength and Conditioning Association (NSCA) bodybuilding drug trial.
The participants were given injections of a drug called dexamethasone, the equivalent of a single pill of insulin.
Some of the injections were given as a placebo and others were given in a form that mimicked insulin injection.
After four weeks, all of the participants were back in the strength and conditioning program.
The researchers then took a look at how those people performed after a period of recovery, comparing the time it took to recover from the injection vs. when the subjects were back to their normal weight and activity level.
For the first time, they looked at the effects of the injection on recovery time.
And they found that, compared to when the injections lasted, recovery time for the injected subjects was faster after the injection.
In other words, when the injected participants returned to their previous weight and activities, they were able to recover more quickly.
“These results suggest that these drug injections can be used to increase muscle strength and endurance during recovery,” the researchers wrote.
“They also suggest that dexametasone may have a greater effect than other injection regimens on restoring muscle strength during recovery, potentially improving the ability to recover after injury.”
In other words: injecting a small amount of insulin into your muscles might not have a huge effect on your body.
The researchers suggest that more research is needed to test the injections against other types of muscle stimulation.
