Pedometers Accelerometers and Observational Methods: A Comparison of Measurements of Physical Activity in Fourth-Grade Students.
<p>In recent years physical inactivity among students has become a matter of great concern. Nearly 65% of students do not meet the daily recommended level of physical activity, which is 60 minutes or more of moderate to vigorous physical activity each day, with 50% of that time being spent in …
