One of the most common excuses most people throw around when asked to include a workout in their schedule is the lack of time. True enough; most fitness regimens today often take at least an hour of one’s time.
But a team of researchers from the McMaster University claims on a study that the length of one’s exercise of fitness routine has nothing to do with its effectiveness. In fact, their findings show that one minute of specialized workout regimen offers the same health benefits as the typical exercise moves.
To determine whether the brief intense interval exercises offer the same benefits as the traditional and time-consuming ones, the group invited 27 men with sedentary lifestyles to participate in the 12-week research/workout program. The study was published in the journal PLOS ONE.
The group was later on divided into three. One group was asked to do sprint interval training (SIT), the other group was assigned to do moderate-intensity continuous training (MICT), and the third group was asked to do nothing for the 12-month period.
“Most people cite ‘lack of time’ as the main reason for not being active,” according to Martin Gibala, lead author of the study.
“Our study shows that an interval-based approach can be more efficient — you can get health and fitness benefits comparable to the traditional approach, in less time,” Gibala said in a statement.
Participants in the SIT group were asked to stick to a specific workout exercise that involves 20 seconds of all-out sprints. After which, participants were required to take two minutes of warm up, then another three minutes to cool down, then they were asked to do a two-minute low-intensity cycling, which they did in between sprints to recover. The MICT group basically followed the same routine, but the routines were five times more, and the participants needed to commit five folds the time in SIT.
At the end of the 12-month period, both the SIT and the MICT groups showed almost the same results. Endurance and insulin sensitivity has significantly improved in both groups by as much as 20 percent.
