In 30 seconds
This systematic review and meta-analysis evaluated the effects of supervised versus unsupervised aerobic exercise on fitness and clinical outcomes in adult clinical populations. The analysis included 30 supervised and 12 unsupervised studies, revealing that supervised exercise significantly improved peak oxygen consumption (V˙ O 2peak) by 0.88 ml min -1 kg -1 and reduced postoperative complications (odds ratio 0.60).
Key findings
- Supervised exercise improved V˙ O 2peak by 0.88 ml min -1 kg -1 (P<0.001).
- Supervised exercise increased 6MWT distance by 0.39 m (P=0.025).
- Postoperative complications were reduced with supervised exercise (odds ratio 0.60, P=0.026).
- High-intensity supervised exercise further reduced complications (odds ratio 0.53, P=0.030).
Why it matters
Understanding the impact of exercise supervision on clinical outcomes is crucial for optimizing prehabilitation strategies. This evidence supports the implementation of supervised exercise programs to enhance patient fitness and reduce postoperative complications.
What to keep in mind
The review was limited by the absence of direct comparisons between supervised and unsupervised exercise groups.
