Aerobic exercise interventions improve cognitive function in older adults with cognitive frailty

This systematic review of 16 RCTs found that 87.5% of studies reported significant cognitive benefits from aerobic exercise interventions in older adults. Pure aerobic and dual-task interventions consistently improved cognition, while intrinsic/embedded interventions enhanced both cognitive and physical outcomes.

Result: Improved cognitive function and physical outcomes

Limitations

  • ⚠Heterogeneous intensity monitoring across studies
  • ⚠Only 6.3% of studies used a double-blind design, increasing potential for bias
  • ⚠Limited to systematic review without meta-analysis

Frequently Asked Questions

What types of aerobic exercise were most effective?▼

Pure aerobic and simultaneous dual-task interventions consistently improved cognition, with dual-task exercises potentially yielding larger executive and memory gains.

How many studies showed cognitive benefits?▼

14 out of 16 studies (87.5%) reported significant cognitive benefits from aerobic exercise interventions.

Were there any negative results?▼

Yes, two studies found no overall cognitive improvement, and one sequential trial showed no cognitive gain. However, one of the negative studies reported improvements in male patients.

What cognitive domains were improved?▼

The review found benefits in verbal fluency, attention, executive function, flanker task reaction time, and sleep quality.
