Maybe catch-up sleep doesn't work to fully repair the damage if you're totally wrecking your body during workdays, but it definitely helps if you're on the borderline. I usually sleep more on the weekends. If I don't, I usually start to manifest cold-like symptoms, indicating that my immune system is struggling. To me, this suggest that catch-up sleep definitely helps in some regards. I can't speak about long-term effects, but I don't think having a malfunctioning immune system would be good for me in the long run either. This is one of those cases where the effect is so clearly pronounced, I utterly don't care what "the medical science" says on the subject. Maybe it's different for different people. (I generally do get 6-7 hours of sleep on any day, though. No idea how people sleep less than 6 hours a day without collapsing at the end of the week.)
