What is the maintenance stage intensity, frequency, and duration for aerobic exercise in older adults?

The maintenance stage for aerobic exercise in older adults typically emphasizes a moderate intensity level that supports continued improvements in cardiovascular fitness and overall health. The correct answer reflects an intensity range of 70-85%, which is effective for maintaining fitness gains and promoting health benefits without leading to overexertion, particularly in older populations who may have varying levels of physical resilience.

The frequency of 3-5 days a week is conducive to ensuring that older adults remain active while allowing for recovery days, which are crucial for reducing the risk of injury and fatigue. The duration of 20-60 minutes fits well within the recommended guidelines, as it allows for flexibility based on individual fitness levels and preferences while ensuring adequate time to derive benefits from exercise.

Engaging in this regimen helps older adults sustain their functional abilities, enhance cardiovascular health, and maintain a higher quality of life.
