Research shows just 40 seconds of high-intensity exercise can deliver tangible results
New research out of Waseda University in Japan has revealed that high-intensity intermittent exercise (HIIE) can be remarkably effective even in short durations.
Published in Medicine & Science in Sports & Exercise, the study found that just 40 seconds of HIIE – specifically two 20-second maximum-intensity sprints (emphasis on the maximum intensity) with a 160-second rest – significantly boosts whole-body oxygen consumption and major muscle activity in the femoral region.
The research highlights that two iterations of 20-second sprints are sufficient for increasing aerobic metabolism and muscle activity, offering a feasible exercise solution for those with tight schedules.
The study advocates for the integration of HIIE into regular routines, promising enhanced endurance and muscle strength with minimal time investment.
“The results of this study,” said Professor Yasuo Kawakami, “are expected to facilitate more efficient training of athletes and help the general public incorporate exercise into their daily lives.”
