The purpose of this study is to examine whether breaking up prolonged sitting with short regular bouts of walking can reduce blood sugar and cholesterol levels after eating, which are risk markers for Type 2 diabetes and heart disease. This study will compare these responses in normal-weight versus overweight/obese South Asian adults.
Participants will attend a preliminary testing session where height, weight, body fat and waist circumference will be measured. They will be familiarised with a motorised treadmill that will be used during the experimental visit below and will take part in an exercise test to determine a light-intensity walking speed for the experimental visit.
Participants will then attend two experimental visits in a random order:
During each visit, blood pressure will be taken 11 times and blood samples will be taken 10 times. Participants will be given a breakfast and lunch meal to consume.

| Prolonged sitting (SIT), then breaking up sitting with walking breaks (INT-SIT) | Experimental | Firstly, participants will remain seated for 5 h and instructed to reduce excessive movement, only rising from the chair to void. After a washout period of at least 3 days, they then performed the INT-SIT condition. Prolonged sitting (SIT): See SIT arm description Breaking up sitting with walking breaks (INT-SIT): See INT-SIT arm description |
|
| Breaking up sitting with walking breaks (INT-SIT), then prolonged sitting (SIT) | Experimental | Firstly, participants will rise from the seated position every 30 min throughout the experimental period to walk on a motorised treadmill at a light intensity walking (as determined during the preliminary test) for 5 min. Participants will start walk on a treadmill at 30 min (so physical activity would be at 30-35 min), 60 min (physical activity will be at 60-65 min), 90 min (physical activity will be at 90-95 min), 120 min (physical activity will be 120-125 min), 150 min (physical activity will be at 150-155 min ), and 180 min (physical activity will be at 180-185 min) in the breakfast postprandial period and 30 min (physical activity will be 30-35 min), 60 min (physical activity will be at 60-65 min), and 90 min (physical activity will be at 90-95 min) in the lunch postprandial period. After performing a walking activity, they will return to the seated position. After a washout period of at least 3 days, they then performed the SIT condition. SIT : See SIT arm description |

Due to an acute bout of physical activity enhancing insulin sensitivity for up to 72 h, each condition was separated by a minimum of three days to eliminate potential carryover effects of the activity conditions. Female participants were asked to indicate the expected date of their menstruation. Based on the information, they were tested between 1 and 10 days in their follicular phase only to minimise the influence of hormonal fluctuations on blood glucose concentrations.
A total of 54 South Asians (BMI>18.0 kg.m^2) aged between 18 and 75 years who were able to walk and perform LPA were recruited; data collection was performed between April 2019 and March 2020.
