New Research Reveals How Often You Need to Exercise to Make It Worth It: The Magic Number
According to recent studies, performing eccentric bicep contractions for three seconds at maximal effort three times per week considerably increases muscle strength. Even while exercising three days per week has advantages, exercising five days per week results in greater gains, emphasizing the significance of consistent, brief exercise.
A recent study sheds light on how frequently exercise must be done in order to gain its effects
Not eager to hit the road or lift weights every day but curious about the health benefits of exercise?
How frequently you should exercise each week to make it useful may be clarified by new Edith Cowan University (ECU) research.
In a recent study, participants made a single, three-second eccentric biceps contraction at their full effort, which is comparable to gradually lowering a heavy dumbbell from a bent arm to a straight arm.
This can considerably increase muscle strength when done everyday for five days a week (Monday through Friday), for four weeks, according to earlier ECU research.
In the new study, participants were divided into two groups, one of which performed a single, three-second contraction twice a week and the other of which did the identical exercise three times a week.
Researchers compared the subjects' bicep strength after four weeks.
The concentric strength (2.5%) and eccentric strength (3.9%) of those who did the exercise three days a week increased somewhat but significantly compared to those who did it two days a week.
The study's principal investigator, Professor Ken Nosaka, said the findings contributed to our growing understanding of how our bodies react to exercise and how people might use that information to their advantage.
Professor Nosaka stated that "our prior work has shown that frequent, brief exercise is more beneficial than one or two big training sessions in a week." We now have a better understanding of the threshold at which such a straightforward activity begins to yield considerable effects. These new findings imply that at least three days per week are necessary, at least for eccentric contraction training for one repetition of three seconds.
Three is decent, but five is superior
While the results indicated that exercising three days per week will have an effect, more activity on a few additional days per week will yield superior outcomes.
Participants in the prior trial who did the exercise five days a week experienced bigger strength gains — more than 10% increases — than the three-day group.
Professor Nosaka emphasized that this did not imply that daily exercise would further enhance outcomes.
"Muscles need rest to improve their strength and their muscle mass," he stated. "Muscle adaptations occur when we are resting." It should be emphasized that while the exercise only lasted three seconds, the study's rest period was about 28,800 times longer than the exercise period. But despite the minimal volume of exercise for muscular building, muscles do seem to prefer to be stimulated more frequently.
Making use of it in real life
More investigation is required, according to Professor Nosaka, to determine whether the study's conclusions hold true for other forms and durations of exercise.
