EE: Physical Activity (2013-2014)

Assessment
How long should a healthy and non-critically ill individual refrain from light intensity physical activity prior to an RMR measurement?
- Conclusion
  There were no studies identified to address how long a healthy or non-critically ill individual should refrain from light intensity physical activity prior to an RMR measurement.
- Grade: V
  - Grade I means there is Good/Strong evidence supporting the statement;
  - Grade II is Fair;
  - Grade III is Limited/Weak;
  - Grade IV is Expert Opinion Only;
  - Grade V is Not Assignable.
  - High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
  - Moderate (B) means we are moderately confident in the effect estimate;
  - Low (C) means our confidence in the effect estimate is limited;
  - Very Low (D) means we have very little confidence in the effect estimate.
  - Ungraded means a grade is not assignable.

How long should a healthy and non-critically ill individual refrain from moderate or vigorous intensity physical activity prior to an RMR measurement?

How long should a healthy and non-critically ill individual refrain from resistance exercise prior to an RMR measurement?
- Conclusion
  Based on one study in healthy, untrained older men performing a single bout of resistance exercise, BMR was reported to be elevated by 3% (57kcal) at 48 hours post-exercise. Therefore, at least 48 hours may be required after 90 minutes of resistance exercise.
- Grade: III
  - Grade I means there is Good/Strong evidence supporting the statement;
  - Grade II is Fair;
  - Grade III is Limited/Weak;
  - Grade IV is Expert Opinion Only;
  - Grade V is Not Assignable.
  - High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
  - Moderate (B) means we are moderately confident in the effect estimate;
  - Low (C) means our confidence in the effect estimate is limited;
  - Very Low (D) means we have very little confidence in the effect estimate.
  - Ungraded means a grade is not assignable.

How long should a healthy and non-critically ill individual refrain from very light intensity physical activity prior to an RMR measurement?
- Conclusion
  Based on the limited evidence reviewed, 30 minutes of rest is required for resting metabolic rate (RMR) to return to baseline after very light intensity physical activity (i.e. less than five minutes of activity) in healthy adults.

  - Grade I means there is Good/Strong evidence supporting the statement;
  - Grade II is Fair;
  - Grade III is Limited/Weak;
  - Grade IV is Expert Opinion Only;
  - Grade V is Not Assignable.
