Summary

The main purposes of this randomized cross-over trial are to test if a 3h/day reduction of time spent in sedentary behaviour (SB) through breaking up hourly and shifting it for standing and walking behaviours would substantially increase total (TEE) and PA energy expenditure (PAEE) compared to a week of habitual prolonged SB, in male and female overweight/obese inactive (which do not attained MVPA recommendations) and sedentary desk workers. Specifically using an experiment design our main aims are: a) to determine the impact of reducing SB on TEE and PAEE; b) to analyse the independent effects of interrupting SB through breaks and the overall reduction in SB on TEE and PAEE; c) To analyse the determinants for the overall reduction in SB; d) If the changes occurred in TEE and PAEE were dependent on specific covariates.

Conditions

  • Risk Reduction Behavior

Interventions

BEHAVIORAL

Reduction of sedentary time by breaking it with low intensity physical activity

One 5-10 minute break per hour during the work day using a software that alert the participant, and perform 6000 steps above the baseline number of steps/day (previously evaluated), by adopting several domain specific strategies, during 7 days.
