STAIRWAY TO HEALTH
US RESEARCHERS have found just a few minutes of vigorous stair climbing would be enough to improve cardiorespiratory fitness.
Previous studies had shown that short bouts of vigorous exercise (sprint interval training) are effective when performed as a single session, with a few minutes of recovery between the intense bursts.
For the study, a group of sedentary young adults vigorously climbed a three-flight stairwell three times a day, separated by one to four hours of recovery. They repeated the exercise three times each week over the course of six weeks.
Compared to a control group who did no exercise the stair climbers were fitter, stronger and also generated more power during a maximal cycling test.
