  • Data are means ± SD unless otherwise indicated.

  • *

    * Logarithm taken for comparing of means.

  • Vigorous activity, >10 consecutive min with >5,724 counts/min; moderate activity, >10 consecutive min with 1,952–5,724 counts/min; sedentary, <100 counts/min; light activity, neither vigorous or moderate activity nor sedentary.

  • Some vigorous activity, some moderate activity during the period accelerometer was worn.
