AB  - The purposes of this study were to (a) examine the stability and consistency of 
      the Caltrac accelerometer (Hemokinetics, Madison, WI) and an activity record to 
      assess physical activity in children and adults (Experiment 1), and (b) to 
      determine if there is a relationship between parents and their children in 
      physical activity level (Experiment 2). Thirty 5-9-year-old children and their 
      biological parents wore Caltrac accelerometers for three consecutive days 
      (including one weekend day). At the same time, parents completed a Caltrac 
      Activity Record (CAL REC) for themselves and their child. Dependent variables 
      were counts per day for the Caltrac and minutes of light activity and activity 
      for the CAL REC. Between-day correlations for the Caltrac ranged from r = .73 to 
      .87 for the parents (p less than .001) and from r = .38 (p less than .04) to .79 
      (p less than .001) for the children. An analysis of variance with repeated 
      measures indicated no significant differences for the Caltrac between days for 
      parents and children. Between-day correlations for CAL REC ranged from r = .67 to 
      .91 (p less than .05) for parents and r = .36 to .72 (p less than .05) for 
      children, and there were no significant differences between days. In Experiment 
      2, chi 2 analyses were used to examine familial resemblance in physical activity. 
      Using the Caltrac, familial resemblance occurred in 67% (father and child) and 
      73% (mother and child) of the families. Using the CAL REC, familial aggregation 
      was present in 70% (father and child) and 66% (mother and child) of the 
      families.(ABSTRACT TRUNCATED AT 250 WORDS)
