NCT02453204

Brief Summary

Research has shown that reducing the time spent sitting can reduce the risk of many diseases, such as diabetes and heart disease, and improve health. It is estimated that many older adults typically spend 70% of their waking day sitting, but little is known about whether reducing sitting promotes health and well-being in this age group. The aim of this research is to investigate the health effects of reducing sitting time by replacing it with short periods of standing or walking in adults over the age of 65.

Outcome Measures

Primary Outcomes (1)

  • Insulin area under the curve

    Samples will be batched and analysed at the end of the study within a certified research laboratory at the Institute of Cardiovascular and Medical Sciences (ICAMS), University of Glasgow. Samples collected at the Leicester Diabetes Centre will be sent by courier in specialist containers and packed with dry ice.

    3 experimental intervention study visits over an estimated period of 1 month

Secondary Outcomes (12)

  • Glucose area under the curve

    3 experimental intervention study visits over an estimated period of 1 month

  • Triglyceride area under the curve

    3 experimental intervention study visits over an estimated period of 1 month

  • 1H NMR Metabolomics spectroscopy

    3 experimental intervention study visits over an estimated period of 1 month

  • Blood pressure

    3 experimental intervention study visits over an estimated period of 1 month

  • Felt Arousal Scale (0-5)

    3 experimental intervention study visits over an estimated period of 1 month

  • +7 more secondary outcomes

Study Arms (3)

Sitting

EXPERIMENTAL

Participants will remain sitting throughout the test period whilst undertaking typical sedentary behaviours such as watching TV, using a computer, reading and writing. Walking and standing will be restricted.

Behavioral: Sitting

Standing

EXPERIMENTAL

Participants will be asked to break their sitting time by standing for five minutes every 30 minutes. Participants will be asked to stand in the same position with no further instructions provided. In total, individuals will accumulate 12 bouts (60 minutes) of standing throughout the test period.

Behavioral: Standing

Walking

EXPERIMENTAL

The walking condition will be identical to standing, but the breaks in sitting time will be punctuated with five minute bouts of self-paced walking rather than standing.

Behavioral: Walking
