Physical activity is considered beneficial for recovery of physical fitness, symptoms of fatigue and distress, and quality of life following lung resection. However, till now there is insufficient insight in the recovery and relevance of physical activity in this process as most studies so far rely on subjective information from questionnaires to capture level of physical activity. Our results show that on average patients experience a complete recovery of health status at six months post surgery to pre-surgery levels. Next to that, higher levels of daily activity were associated with better health status. Interestingly, part of NSCLC patients deploy below-average physical activity. A next step would be to investigate whether ambulant monitoring of both symptoms and daily activity optimizes recovery of health status after lung resection.
