PMID 33570280WHAT IT FOUND
During haemodialysis, supervised resistance exercise showed significant pooled physical performance effects, but protein intake, energy intake, and quality of life did not change significantly.
It may be a low-cost addition to dialysis care.
Key findings
01Pooled physical performance outcomes showed significant standardized mean differences: 0.517 for the 6-minute walk test (p = 0.000), 0.422 for sit-to-stand 30 (p = 0.008), and 0.353 for grip strength (p = 0.003).
02Pooled nutrient intake analyses were not significant: dietary protein intake 0.138 (p = 0.328) and dietary energy intake 0.108 (p = 0.441).
03Pooled quality of life analyses were not significant: physical component score 0.226 (p = 0.055) and mental component score 0.129 (p = 0.082).

What it does not show
Only five studies used allocation concealment, and blinding was limited: two studies blinded participants and therapists, and three studies blinded assessors. The included trials were small, with sample sizes per trial ranging from 15 to 77 participants. Exercise prescriptions varied in frequency, intensity, duration, and type, so the optimal dose is unclear. The methods say English and Chinese studies were included, but the limitations say the review was restricted to English, so relevant literature may have been missed. The physical performance results are inconsistently worded: the results report significant decreases for the walk test and sit-to-stand and an increase for grip strength, while the conclusion says performance improved. Nutrient intake and quality of life outcomes were null, so the paper does not support using exercise primarily for those effects.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that intradialytic resistance exercise improves nutrient intake or quality of life. The pooled dietary protein, dietary energy, physical component, and mental component analyses were not significant.
