The study looked at how aging affects walking, balance, and strength in people over 50. They tested grip and knee strength, balance on one leg, and how people walk. The results showed that as people get older, their knee and grip strength decrease, and their balance gets worse. However, walking speed doesn't change much with age. Men and women both experience these changes, but only strength is affected differently between the sexes. Overall, standing on one leg for a long time is the best way to see how well someone is aging, regardless of gender.
