Jordan et. al. (2016)
30 people were recruited for this research – they are called the ‘participants’. They were all healthy, but ‘sedentary’ – this means they did not do any regular exercise during the day.
The researchers got them to take part in three different ‘conditions’ on different days:
- In the first condition the participants had to sit for 6 hours. During this time they were allowed to read, use a computer and watch TV.
- The second condition was the same as above except that the participants were instructed to carry out 30 minutes of moderate-intensity walking in the morning.
- In the third condition, the participants were instructed to take six ‘exercise snacks’ to break up the six-hour sitting period. These were five-minute walks every hour across the six hours.
Results:
- Both the 30-minute walk and the 5-minute exercise-snack walks resulted in participants reporting increased energy levels at the end of the day
- However, unlike the other conditions, the 5-minute exercise snack walks also improved mood and reduced food cravings at the end of the day
Conclusions:
- Short bursts of activity during the workday is a promising approach to improve overall wellbeing
