Exercise in Dialysis: Ready for Prime Time?

Area of Science:

• Nephrology
• Exercise Physiology
• Public Health

Background:

• Patients with end-stage kidney disease on maintenance hemodialysis (HD) often experience physical inactivity and dysfunction.
• Despite extensive research demonstrating health and quality-of-life improvements, exercise interventions are rarely implemented in dialysis clinics.

Purpose of the Study:

• To review recent large randomized clinical trials on exercise in HD patients.
• To discuss novel strategies for implementing and evaluating exercise interventions in HD.
• To identify policy needs for enhancing exercise prescriptions in this population.

Main Methods:

• Critical review of data from recent large randomized clinical trials.
• Discussion of global novel approaches to exercise prescription and evaluation.
• Analysis of policy implications for exercise in HD.

Main Results:

• Exercise interventions, particularly intradialytic cycling, have shown benefits in strength, physical function, and cardiovascular risk factors.
• Emerging approaches focus on diverse exercise options and motivational tools, with increasing emphasis on patient-reported outcome measures (PROMs).

Conclusions:

• Significant advances have been made in exercise interventions for HD patients, but widespread implementation and optimal efficacy require further research and policy support.
• While promising, exercise in dialysis is not yet fully optimized, necessitating continued innovation and integration into standard care.
