Table 2.

Energy expenditure during sedentary bouts with and without an activity break (mean ± SE, N = 20).

	Bout 1	Bout 2	Bout 3	Bout 4
Gross EE (kcal/30 min)	43.9 ± 2.09^{b, c, d}	47.13 ± 2.2^{a, c, d}	51.49 ± 3.02^{a, b, d}	60.45 ± 3.51 ^{a, b, c}
Net EE (kcal/30 min)	7.49 ± 1.23 ^{b, c, d}	10.49 ± 1.38 ^{a, c, d}	14.85 ± 1.61 ^{a, b, d}	23.96 ± 2.04 ^{a, b, c}
Relative Net EE (kcal/30 min/kg lean body mass)	0.14 ± 0.03 ^{b, c, d}	0.20 ± 0.03 ^{a, c, d}	0.26 ± 0.03 ^{a, b, d}	0.42 ± 0.05^{a, b, c}

^asignificantly different than bout 1 (p < .05).

^bsignificantly different than bout 2 (p < .05).

^csignificantly different than bout 3 (p < .05).

^dsignificantly different than bout 4 (p < .05).

Note. Bout 1 consisted of 30 consecutive minutes of sitting. Bout 2 consisted of 14 minutes of sitting, 1 minute of walking, and 15 minutes of sitting. Bout 3 consisted of 13 minutes of sitting, 2 minutes of walking, and 15 minutes of sitting. Bout 4 consisted of 13 minutes of sitting, 5 minutes of walking, and 12 minutes of sitting.
