Yes running can help you grow taller, so can swimming and cycling. Along with a balanced diet you can add on height. It has beens proven by scientists. It would also be a good idea to run with ankle weights on. Scientists have shown that running with weights on creates tiny fractures or gaps (called microfractures) in your bone. It's proven that if you stretch after creating the microfractures it can help the bone grow, but it's best to stretch immediately (5-20 minutes) after your workout because microfractures disappear after 20 minutes.
Inversion tables don't help you grow, but may help you stand a little taller.
