One Minute of Exercise per Day May Improve Bone Health
As we age, our bones become more brittle, increasing the risk of dangerous and debilitating breaks. A recent study suggests that doing even one minute of high-intensity, weight-bearing exercise equivalent to a medium-paced run for pre-menopausal women or a slow jog for post-menopausal women was associated with better bone health.
Participants in the study included more than 2,500 women. The women wore activity-tracking monitors for one week and their bone health was measured by an ultrasound scan of their heel bone.
At the conclusion of the study, the researchers found that the women who did an average of 60 to 120 seconds of high-intensity, weight-bearing activity per day had 4% better bone health than those who did less than a minute. They also found 6% better bone health in women who did more than two minutes per day of that type of exercise.
Researchers from the University of Exeter conducted the study. It was published on June 29, 2017, in the International Journal of Epidemiology.
The exercise in this study is an example of extremely short high-intensity interval training. High-intensity interval training is a type of exercise that involves rotations of strenuous exercise with less strenuous exercise. Studies suggest that it is an effective way to both lose weight and build muscle.
