Why Intensity Matters for Preserving VO2 Max as You Age
Researchers behind Norway's Generation 100 project followed adults aged 70 to 77 in Trondheim, randomising them to standard public health activity guidelines or to twice-weekly supervised sessions at either 70 percent or 80 percent of max heart rate. The programme ran for five years, and a new analysis from the team, led by Sindre Midttun, tackles the question of how hard older exercisers should push. The coverage's answer is that intensity plays a real part in preserving VO2 max as the years stack up. The excerpt does not spell out how large that advantage is, so treat the direction as the story rather than any particular number.
For you: If you exercise in your 70s, this is a reason to think about how hard your sessions are, not just how often they happen.
