Key result
Compared with prolonged sitting, 30 minutes of continuous moderate walking reduced mean 18.7-h glucose (5.1 vs 5.6 mmol/L, P<0.001) and systolic blood pressure (119 vs 122 mm Hg, P<0.05).
Why the study?
Does interrupting prolonged sitting with walking breaks or continuous walking improve glucose control and ambulatory blood pressure in overweight/obese, physically inactive adults?
Population
10 overweight/obese, physically inactive participants (5 men; mean age 32 ± 5 yr; BMI 30.3 ± 4.6 kg/m2)
Comparison
30 min continuous moderate-intensity walking, or… vs 9 h of prolonged sitting
Design
RCT, randomized four-trial crossover study
Follow-up
18.7 hours

May support walking breaks for glucose control in overweight adults; leaves open optimal protocols and BP effects in larger trials.

Does interrupting prolonged sitting with walking breaks or continuous walking improve glucose control and ambulatory blood pressure in overweight/obese, physically inactive adults?
Absolute Event Rate: 5.1% vs 5.6%
p-value: p=<0.001
Continuous 30-minute moderate-intensity walking is more effective than short walking breaks for improving both glucose control and systolic blood pressure in overweight/obese inactive adults.
Bhammar et al. (2017) conducted an RCT in Overweight/obese, physically inactive (n=10). Walking breaks or continuous walking vs. Prolonged sitting (9 h) was evaluated on Mean 18.7-h glucose (p=<0.001). Compared with prolonged sitting, 30 minutes of continuous moderate walking reduced mean 18.7-h glucose (5.1 vs 5.6 mmol/L, P<0.001) and systolic blood pressure (119 vs 122 mm Hg, P<0.05).
