The Claim

In individuals with stage-3 chronic kidney disease, resistance training performed once or three times per week for 12 weeks results in similar increases in leg press strength (57%), knee extension strength (30%), physical function (as measured by sit-to-stand tests), and reduction in uraemic symptoms.

In plain English

For people with stage-3 chronic kidney disease, doing resistance training once or three times a week for 12 weeks leads to the same improvements in leg strength, physical function, and reduction of uraemic symptoms.

See the scientific wording

In individuals with stage-3 chronic kidney disease, resistance training performed either once or three times per week for 12 weeks produces similar improvements in leg press and knee extension strength (57% and 30% increases, respectively), physical function (sit-to-stand tests), and reduction in uraemic symptoms, indicating that lower training frequency is sufficient for these outcomes.

Why this might work

When a person with kidney disease performs resistance exercises, their nervous system becomes more efficient at activating muscles, allowing them to produce more force without needing larger muscles. This improved nerve signaling also makes everyday movements like standing up from a chair easier. At the same time, the muscles work better at clearing waste products and reducing inflammation, which lessens symptoms like fatigue and muscle stiffness.

  1. Study: Resistance Exercise in People With Stage-3 Chronic Kidney Disease: Effects of Training Frequency (Weekly Volume) on Measures of Muscle Wasting and Function

    For people with moderate kidney disease, doing leg workouts once a week improves strength, walking ability, and how they feel just as much as doing them three times a week — even though muscles get a bit bigger with more workouts, the real benefits are the same.
