In sport, is there a limitation for human physical and biological capabilities?

Question

In sport, will the human in future keep breaking the records of their counterparts in the past? Or, will us reach a limit for our physical biological limit? Let imagine, if there is no limitation, it means the physical capabilities can be improved and do something the past generations can't.

Answer 1

The record will be broken from time to time - due to nutrition control and technologies (especially for track and field). Unless extreme mutation happens, evolution of human body will not exceed what our skeleton and muscle system can hold (which is why Mothra can only be a fiction). We will eventually reach a limit, or even begin to regress.

I also don't think the future human can jump 30 meters, or run 100 meters in 3 seconds based on our body strength.

Answer 2

In the short term, one would assume that we'll reach a limit. People continue to improve because we keep learning more about training and nutrition. At some point we'll now what the optimum training regimen is, and what the ideal nutrition is, and athletes will be on such regimens from a very young age until they retire. They will achieve the maximum that a human can achieve at that time.

Over a (very much) longer period of time, man could get better at some events due to changes in the species. This would be a much slower change, of course.
