The desk jockey survival guide

TL:DR

  • Increased time spent sedentary has been correlated with health problems such as diabetes and obesity
  • Break up your sedentary time, take a break every hour
  • Sit less, move more, feel better

Introduction

Sedentary Behavior

Sedentary behaviors (from the Latin sedere, “to sit”) include sitting during commuting, in the workplace and the domestic environment, and during leisure time. Basically behaviors which involve sitting and low levels of energy expenditure roughly 1.0 to 1.5 METs (1MET = 1 kcal·kg−1·h−1).

Globally, the world’s population is moving less and less. Most of us, including the youth, spend an average 7 to 10 hours engaged in sedentary behaviors. Even those who exercise regularly are guilty of it. In fact, they may even be spending more time engaging in sedentary behavior than the average joe.

Why is sitting bad?

From a meta-analysis and systematic review published in in the medical journal Diabetologia, increased time spent sedentary has been associated with:

  • 112% increase in risk of diabetes
  • 147% increase in cardiovascular events
  • 90% increase in death due to cardiovascular events
  • 49% increase in death due to any cause

In addition, as Bret Contreras notes in his article “The Deleterious Effects of Sitting”, sitting;

  • reduces fat-burning enzymes by 50%.
  • decreases the HDL:LDL cholesterol ratio, increases the risk of diabetes, increases the risk of heart disease, increases the incidents of depression, increases the risk of acquiring metabolic syndrome
  • increases incidences of discomfort, chronic disorders, arthritis, inflamed tendons, chronic joint degeneration, impaired circulation, varicose veins, hypertension, obesity, cancer, high blood triglycerides, high blood sugar, osteoporosis, and herniated discs

In addition, too much sitting causes inhibited gluteal muscles (butt muscles) aka “Gluteal Amnesia”. Which means that the gluteal muscles atrophy and become weak. This results in other muscles having to compensate for it and cause your posture and movement patterns to erode. Leading to problems such as lower back pain, tight hamstrings and a higher probability of lower limb injuries.

Taking action

Due to the nature of our jobs, we have to be at our desks for the majority of our waking hours. And unless your company is nice enough to sponsor you a walking or standing desk, you’re dead in the water. So what can you do about it?

Be a “breaker”

From the AusDiab study taking breaks when sedentary were correlated with improved metabolic biomarkers compared to “prolongers” who spend large chunks of time sedentary, even when total accumulated time spent sedentary was the same. Breaks can be just standing up from sitting, taking a walk or just doing some stretching. Basically any activity that interrupts the sedentary behavior.

Another finding from the AusDiab study is that a higher frequency of breaks in sedentary time has a positive effect on waist circumference, body mass index, triglycerides and glucose levels. Even after taking into account total sedentary time and the amount and intensity of exercise the study participants took part in. As shown in the chart below, those who took the least breaks had a 6cm larger waist circumference than the most frequent breakers
