PMID 31220327WHAT IT FOUND
Patients with aneurysmal subarachnoid hemorrhage had low fitness one year after onset.
Those who were more physically active had higher oxygen uptake and leg strength. Patients treated with surgical clipping had significantly lower fitness than those treated with coiling.
Key findings
01Physical fitness remained low over the first year, with more than one-third of participants classified as having very poor cardiorespiratory fitness at both 6 and 12 months.
02Higher total physical activity was associated with better cardiorespiratory fitness and knee flexion strength, but sedentary behavior showed no relationship with fitness measures.
03Patients treated with surgical clipping had 22% lower cardiorespiratory fitness and 29% lower knee extensor strength compared to those treated with endovascular coiling.

What it does not show
Not all measurements were available for all participants, which might have led to selection bias. The study could not confirm causality between physical activity and fitness levels. Interaction terms could not be studied due to insufficient statistical power. A CPET practice trial was not implemented, so the observed improvement in fitness may be an overestimation due to practice effects. Physical activity was measured over only 3 consecutive weekdays, which may not be representative of routine activity.
Declared interests
The funders had no role in the design, analysis, write-up, or decision to submit for publication.
The easy way to misread this
Do not assume that reducing sedentary behavior alone will improve fitness. This study found no relationship between sedentary behavior and physical fitness, whereas higher total physical activity was associated with better fitness.
