Abstract
End-stage kidney disease (ESKD) patients receiving hemodialysis experience
substantial physical and psychological burdens that negatively affect their quality
of life (QoL). Frequent hospitalizations, treatment-related fatigue, and functional
limitations commonly restrict daily activities and reduce overall well-being.
Physical inactivity is particularly prevalent among dialysis patients and has been
identified as an independent predictor of increased mortality and poor clinical
outcomes. Furthermore,
complications such as anemia, muscle fatigue, muscle atrophy, and reduced aerobic
capacity further limit physical activity, increase the risk of falls, and contribute
to diminished QoL. Consequently, physical fitness has emerged as an important
determinant of survival and functional status in individuals with ESKD. QoL among dialysis patients varies
significantly across regions due to differences in socioeconomic conditions,
healthcare infrastructure, and access to dialysis services. In the Middle East, individuals
undergoing dialysis often experience poorer overall health outcomes compared with
global averages. In Qatar
specifically, factors such as sleep disorders and depression have been shown to
further reduce QoL and increase the perceived burden of treatment. Although exercise interventions have
been explored as a potential strategy to improve physical and psychosocial outcomes,
the evidence remains inconsistent. For example, a randomized controlled trial
involving 87 participants found no significant improvement in physical QoL after a
3-week exercise intervention, although important social and environmental domains
were not assessed. Intradialytic resistance exercise (IRE) has been increasingly recognized as a
beneficial intervention for hemodialysis patients. Previous studies have
demonstrated that medium- to high-intensity intradialytic resistance training
(IRE) can safely improve muscle strength, muscle mass, and dialysis efficiency in
patients with sarcopenia.
Similarly, a 6-month resistance training program significantly improved muscle
strength and physical performance in a multicenter retrospective study of
hemodialysis patients. Despite
these benefits, the integration of structured exercise programs within dialysis care
remains limited. Another common complication affecting dialysis patients is muscle
cramping, which occurs in up to 79% of individuals undergoing hemodialysis
and frequently develops during the final hour of treatment. Preliminary evidence suggests that
resistance-based interventions, including stretching exercises, may reduce muscle
cramps by lowering electromyography (EMG) activity through stimulation of the Golgi
tendon organs. However,
empirical evidence specifically examining the effects of IRE on muscle cramps
remains scarce. In addition to physical symptoms, dialysis adequacy plays a crucial role in
determining patients’ QoL. Inadequate dialysis has been associated with
poorer physical and psychological outcomes, whereas improved dialysis adequacy may
enhance patient well-being.
While intradialytic exercise has been suggested as a potential strategy to improve
dialysis efficiency and physical function, its implementation in routine clinical
practice remains limited. Nevertheless, international guidelines such as the 2016
Kidney Disease Outcomes Quality Initiative (KDOQI) and national recommendations in Qatar advocate the
incorporation of physical exercise into dialysis care.
