Regular physical activity improves maximum aerobic power (cardiorespiratory fitness) by 10-20% in average urban city-dwellers, bringing their performance levels closer to those observed in circumpolar Scandinavian populations.

Engage in regular physical activity to boost your aerobic fitness. While specific protocols aren't detailed here, the goal is to improve your maximum oxygen intake by 10-20%. This brings your fitness closer to optimal levels seen in active populations. Start now, as the activity is likely beneficial and pleasant, rather than waiting for perfect scientific certainty.

there are good grounds for the belief that the average Canadian city-dweller could improve his aerobic power by 10-20% through a program of regular physical activity; his performance would then approach that reported from Scandinavia.

Why this rating

The paper is an editorial summarizing a symposium; it cites observational data and expert opinion rather than a single controlled trial, noting that 'rigorous scientific proof... may take another hundred years'.
