Like several thousand other exercise researchers, I’ll be heading to San Francisco this week to attend the American College of Sports Medicine conference. This is my first ACSM, and so I am very excited.
I’m sure there is going to be plenty of awesome sessions to attend at the conference, but I wanted to let people know about two events in particular.
1. SBRN Lunch Meeting
As regular readers of the blog will know I am a proud member of the Sedentary Behaviour Research Network (SBRN), which is the only organization focused explicitly on sedentary behaviour. SBRN member Ernesto Ramirez has organized a lunch for anyone interested in sedentary behaviour, which will take place on May 31 at 11:30am at the Chieftan Pub (within walking distance of the conference). The event is free (although you do need to pay for your own lunch), and open to anyone interested in sedentary behaviour.
If you’re planning on coming, please RSVP here so that we can make sure we have enough tables reserved. So far we’ve got 13 folks signed up, and we’d love to have more. There is no fixed agenda, just a chance to network with other people who are interested in the health impact of sedentary behaviour.
There were similar SBRN meetups at the recent ICDAM conference in Italy and at ISBNPA in Austin, Texas, and we’re hoping it continues at other events down the road.
2. My poster session – come say hello!
For anyone who is interested, my presentation takes place from 9:30-11:00am at session G-30 on June 2 (Poster Board # 50) and is titled “Acute Sedentary Behavior and Markers of Cardiometabolic Risk: A Systematic Review of Intervention Studies”. As the title suggests, it will focus on our systematic review of the health impact of short bouts of sedentary behaviour. For those who are skeptical that a short bout of bed rest or sitting could have a measurable health impact, you may want to check out this recent post on the topic. The presentation will be based on this paper which is now in press at the Journal of Nutrition and Metabolism.
Here is the abstract from the paper itself (which is slightly updated from the presentation abstract):
North Americans spend half their waking hours engaging in sedentary behaviour. Although several recent interventions suggest that short bouts of uninterrupted sedentary behaviour may result in acute increases in cardiometabolic risk, this literature has not been reviewed systematically. This study performed a systematic review of the impact of uninterrupted sedentary behaviour lasting ≤7 days on markers of cardiometabolic risk (insulin sensitivity, glucose tolerance, and insulin, glucose and lipid levels) in humans. Interventions were identified through systematic searches of Medline and Embase, and screened by 2 independent reviewers. A total of 252 interventions were identified that examined the impact of imposed sedentary behaviour on biomarkers of interest. The majority of these studies focused on healthy young men, with very little identified research on females or other age groups. We found consistent, moderate quality evidence that uninterrupted sedentary behaviour ≤7 days results in moderate and deleterious changes in insulin sensitivity, glucose tolerance and plasma triglyceride levels. In contrast, there is inconsistent, very low quality evidence linking uninterrupted sedentary behaviour with changes in glucose tolerance, insulin, glucose, HDL- and LDL-Cholesterol levels. These findings suggest that uninterrupted bouts of sedentary behaviour should be avoided in order to prevent or attenuate transient increases in metabolic risk.
