Do Staff Members At Queen Margaret University Meet Current Daily Physical Activity Guidelines And Does A Relationship Exist Between These Activity Levels And Cardiovascular Fitness?
(2013) Do Staff Members At Queen Margaret University Meet Current Daily Physical Activity Guidelines And Does A Relationship Exist Between These Activity Levels And Cardiovascular Fitness?, no. 91.
Introduction: The UK department of health set guidelines in 2011 to complete 30 minutes of activity 5 days a week, with bouts lasting longer than 10 minutes at a time (Department of Health, 2011; NHS, 2008). Although individuals may be meeting daily activity requirements, prolonged sitting in a work environment can significantly impact an individual's health and increase metabolic risk factors (Hamilton et al. 2007). It is suggested that sedentary behavior is directly related to an increased risk of obesity, abnormal glucose metabolism and cardiovascular diseases (Owen et al. 2009; Wilmot et al. 2012). However, it is unclear how sedentary behavior may influence these risk factors and the length of sedentary time that is detrimental to health. The current research is to objectively quantify and analyze the amount of physical and sedentary activity staff at QMU partakes in during the work day and during non-work days. Methods: Cross-sectional study with 10 Queen Margaret University staff members participated in two data analysis sessions on top of wearing an accelerometer for 7 consecutive days to collect physical activity levels throughout work and non-work days. Anthropometric data, height, weight, blood pressure, fasting blood glucose and arterial stiffness were measured and analyzed with respect to subjects work day physical activity and sedentary behavior levels. Results: Time spent engaged in sedentary behavior during work days is significantly greater than sedentary behavior during non-work days, 75% and 59% of 8 hour/day wear time respectively. Results showing 11% and 15% of an 8 hour/day wear time attributed to moderate to vigorous activity on work and non-work days respectively. Significant findings show that subjects remain in sedentary behavior for greater time during working days than on non-work days, p=0.025. Results also show that with the majority of the day occupied by sedentary behavior trending correlations occurs with increases in body mass index, pulse wave velocity, and blood pressure measurements where as a trending negative correlation occurs with subject's blood glucose levels. Conclusion: Current research in daily sedentary behavior suggests that quantity of daily sedentary behavior alongside how sedentary time is accumulated has an impact on health functions and associated cardiovascular and metabolic risk factors. More specified research is required in this field to allow conclusions on sedentary physiology and its effects on cardiovascular and metabolic health, and recommendations with respect to simple strategies in the workplace to decrease the amount of sedentary time that occupies a work day.
