A new study presented by the American College of Sports Medicine shows that interactive video games can improve physical fitness in seniors.

According to the study, sedentary seniors from Stamford became more active once they got involved in the competition of games like Wii tennis, which require players to jump and move around.

The study also indicates that playing interactive video games not only boosts older adults' fitness by increasing their heart rate, but also lifts their spirits and makes them feel energized.

"People can gain strength and mobility when they're 90-95 years old," says Michael Morgan, of Darien Physical Therapy. "[The] problem is they get old and sedentary. It's the old adage, 'if you don't use it, you lose it.'"
