What Do We Really Know about Exercising with Complications?
As a clinical exercise researcher, I frequently have found it difficult to study exercise effects in people with health complications, even though this is critical information to know in order to make appropriate exercise guidelines. Try convincing your university Institutional Research Board, or IRB, that it is advisable to exercise people with eye issues like unstable proliferative retinopathy to find out if breath-holding, jumping, jarring, or head-down activities cause them to experience retinal hemorrhages. Understandably, that is not going to happen, nor should it.
In some cases, I have not even been allowed to study relevant populations—like when we wanted to study older adults with type 2 diabetes and balance or gait issues related to peripheral neuropathy. Our IRB required so many exclusionary criteria that we were only able to recruit healthy, older subjects with diabetes, not the ones for whom an exercise training intervention to improve balance would be most relevant (i.e., those with actual balance issues).
It is still worth revisiting the latest recommendations for exercising safely and effectively with a variety of diabetes-related health complications. Most of these are derived from clinical observations and practical experience rather than clinical studies, though. The table that follows is a compilation of all these recommendations.
