*A bout of sedentary behaviour is a period of consecutive minutes where the accelerometer registers <100 cpm.
†Percentage of sedentary bouts, number of sedentary bouts of n min/number of sedentary bouts of 1 min.
‡Percentage of sedentary time, length of sedentary bouts of n min/length of sedentary bouts of 1 min.
