Sedentary Lifestyle

Regularly interrupting sitting with standing, walking, or simple resistance exercises can improve cardiometabolic biomarkers over a single day in people with type 2 diabetes or impaired glycaemia. Weekday sitting time was underestimated by the cIPAQ-SF by a mean of 3.5 hours per day. Sedentary behaviour is defined as low-energy waking activity while sitting, reclining, or lying. The cIPAQ-SF showed moderate correlation with activPAL for both weekday (r = 0.577) and weekend (r = 0.444) sitting time. Social constraints outside work, such as entertaining visitors and social norms that encourage sitting, have rarely been studied as barriers to sedentary behaviour change but may be powerful influences. Previous sedentary behaviour interventions have predominantly focused on workplace sitting, especially computer-based work, limiting their relevance to non-work settings and people with long-term conditions. Sedentary behaviour is formally defined as sitting or lying during waking hours with low energy expenditure. Exercise builds cardiovascular reserve, allowing the heart and lungs to cope with physiological stress; without this buffer, moderate stressors can become life-threatening. Th…
